Economics

Begin with choices, markets, and incentives, then study firms, strategic behavior, and market failures. Move into macroeconomics and international trade before finance, development, institutions, and economic thought.

Markets, Production, and Strategic Choice

Build from scarcity and incentives to markets, production, and strategic choice.

Economic Questions

• economics — Economics is the social science that studies production, consumption, prices, markets, and incentives, and is often divided into microeconomics and macroeconomics. Its history includes the Physiocrats, Adam Smith, John Maynard Keynes, Milton Friedman, and the Chicago School, and it is sometimes called the dismal science.

Core Microeconomics

• Markets, Prices, and Elasticity

  • Scarcity and opportunity cost — limited resources force choices among competing uses. The opportunity cost of a choice is the value of the best alternative forgone, including uses of time as well as money. Marginal analysis compares the additional benefit and additional cost of a small change; sunk costs are already irrecoverable.¹

  • Supply and demand — the core model: quantity supplied rises with price; quantity demanded falls with price. Equilibrium is where supply and demand curves intersect. The relationship is often traced to Adam Smith and is commonly presented in introductory economics graphs.

    • cobweb model — The cobweb model is an economic model of cyclical price fluctuations when supply is produced before price is observed. It is associated with Nicholas Kaldor and with stability or instability depending on the relative slopes of supply and demand.

    • Law of Supply — The law of supply states that, other things being equal, a higher price tends to lead producers to offer more of a good for sale. It expresses a generally direct relationship between price and quantity supplied.

    • market equilibrium — Market equilibrium is the point at which supply and demand balance so that neither price nor quantity is under pressure to change. It is often discussed in terms of efficiency and the effects of externalities.

    • supply — Supply is the amount of a good producers are willing and able to offer at a given price. In standard graphs it slopes upward in the short run, and in macroeconomics aggregate supply is often contrasted with demand and with long-run verticality.

    • supply curve — The supply curve shows how much producers are willing to sell at different prices, and it slopes upward in the usual market model. Market equilibrium occurs where it intersects the demand curve. In economics and monetary policy, the idea also appears in discussions of the supply of money and related shifts in market conditions. The same curve is used in elasticity and equilibrium problems.

  • Consumer surplus / producer surplus — consumer surplus: the difference between willingness-to-pay and market price; producer surplus: the difference between market price and minimum willingness-to-sell. Together they compose total welfare.
    • consumer surplus — Consumer surplus is the benefit buyers receive when they pay less than the maximum they would be willing to pay. It is represented by the area under the demand curve and above the market price, and it is central to welfare analysis in microeconomics.

  • Price ceiling / price floor — a ceiling (set below equilibrium) causes shortages; a floor (set above equilibrium) causes surpluses. Classic examples: rent control (ceiling), minimum wage (floor).

  • Elasticity of demand — percentage change in quantity demanded divided by percentage change in price. Demand is elastic when

    E

    > 1, inelastic when

    E

    < 1, and unit elastic when

    E

    = 1. Along a demand curve, a price rise reduces revenue in the elastic region and increases it in the inelastic region; unit elasticity gives no first-order revenue change. Revenue maximization is distinct from profit maximization.2

    • income elasticity of demand — Income elasticity of demand measures how the quantity demanded of a good changes when consumer income changes. A value above one indicates a luxury good, a value between zero and one indicates a necessity, and a negative value indicates an inferior good.

  • Income elasticity — positive for normal goods; negative for inferior goods (e.g., bus travel for high-income consumers). Luxury goods have income elasticity > 1.

  • Cross-price elasticity — positive for substitutes; negative for complements.

  • Demand and supply
    • demand curve — The demand curve graphs how much of a good consumers want to buy at a given price, usually sloping downward as price rises. It is central to supply-and-demand analysis, with special cases such as kinked demand in oligopoly and exceptions like Veblen or Giffen goods.
  • markets — Places where buyers and sellers exchange goods and services. They include street bazaars, floating markets, souks, tianguis, neighborhood stalls, national markets, foreign-exchange markets, and historic urban market complexes such as Trajan’s Market. They are central to economics and everyday commercial life as systems of price formation and trade.
    • market — A market is the economic setting in which goods and services are bought and sold. It can appear in literature as a human-made place of trade, such as a goblin market or a Saturday market.

  • price — The quantity a buyer pays for a good or service, and the money cost plotted against supply and demand in elementary economics. It is the choice variable in the Bertrand model of oligopoly, and economists discuss price stickiness, menu costs, price takers, market power, rent ceilings, floors, and price discrimination by monopolies in relation to it.

  • pricing
    • prices — Prices are the amounts sellers ask for goods and services, shown on the vertical axis of standard supply-and-demand graphs. They rise during inflation, and economists discuss rigidities like menu costs, floors and ceilings, and price discrimination when they do not adjust smoothly.
  • Price ceilings
    • rent control — Rent control is a price ceiling on housing that limits what landlords may charge tenants. It is especially associated with New York City and is often criticized by economists for reducing supply, maintenance, and mobility.
  • price controls

    • Price Ceiling — A price ceiling is a legal maximum on the price of a good or service, usually set to keep essential items affordable. Governments from Diocletian to Nixon have tried versions of this policy.

    • Price floor — A price floor is a legal minimum price set for a good, usually above equilibrium. It is a form of price control; examples include the minimum wage and agricultural support prices. When binding, it can transfer surplus toward producers but creates deadweight loss.

  • Elasticity

    • perfectly inelastic — Perfectly inelastic describes a quantity that does not respond to changes in price, so elasticity is zero. The term is also used in simple models of labor supply when workers are assumed to supply the same amount of labor regardless of wage.

    • price elasticity — Price elasticity describes how responsive a good’s price or quantity demanded is to changes in supply or demand. For demand, it tends to rise when substitutes are available, when the good takes a larger share of income, and when the consumer has more time to adjust.

  • Demand theory
    • normal good — A normal good is a good for which demand rises when income rises and falls when income falls, so it has positive income elasticity of demand. Economists contrast it with an inferior good, whose consumption tends to fall as income increases. In consumer theory, a normal good is often described as having a positive wealth effect, and for a necessity-like normal good the income elasticity is usually between zero and one.
  • wage floors
    • minimum wages — Minimum wages are legal wage floors that set the lowest hourly compensation an employer may pay. They are often discussed in debates over monopsony, employment effects, and policies such as the Fight for $15.
• Consumer Choice and Welfare
  • Marginal utility — additional utility from consuming one more unit; diminishing marginal utility is the standard assumption. Rational consumers equalize marginal utility per dollar across goods. It is a central idea in consumer theory, where consumers compare marginal utility against price; expected utility theory and prospect theory are common related frameworks.
    • Marginalism — Marginalism is an economic theory that emphasizes utility and demand in determining price, especially under conditions of competition. It holds that people allocate resources by comparing the usefulness of successive units, a principle known as marginal utility. The farmer-and-parrots example illustrates this idea: when faced with a loss, one cuts the least important use first rather than reducing all uses proportionally. It is associated with Stanley Jevons, Carl Menger, and Alfred Marshall.

  • Indifference curves — combinations of two goods giving equal utility; convex to the origin. Budget constraint defines affordable combinations; utility-maximizing choice is at the tangency. The marginal rate of substitution is the slope of an indifference curve in consumer theory.

  • Giffen good — a (rare) inferior good whose demand rises when its price rises, because the negative income effect dominates the substitution effect. It is often illustrated by staple foods such as potatoes, bread, or rice when they take up a large share of a consumer’s income; potatoes during the Irish Famine are the standard example.

  • Veblen good — demand rises with price due to status signaling; not Giffen (different mechanism). Luxury goods like diamond-tipped canes are classic examples used to contrast Veblen goods with ordinary demand curves.

  • Edgeworth box — a diagram placing two consumers’ (or countries’) indifference curves in a shared rectangular space; the contract curve traces all Pareto-efficient allocations within it; developed by Francis Ysidro Edgeworth. It is used to show how two consumers can divide a fixed set of goods and reach Pareto-efficient allocations.
    • contract curves — Contract curves are the loci of Pareto-efficient allocations in an Edgeworth box. They mark points where two agents’ indifference curves are tangent and their marginal rates of substitution are equal.

  • Pareto efficiency (Pareto optimum) — an allocation is Pareto efficient if no reallocation can make any agent better off without making at least one worse off; a minimal welfare standard, not an equity criterion.

  • Revealed preference — Paul Samuelson’s approach: infer consumer preferences from observed choices rather than introspective utility; foundational to modern demand theory. It is associated with axioms such as WARP, SARP, and the strong axiom of revealed preference.

  • Substitution effect vs income effect — a price change has two components: a substitution effect (relative price shift) and an income effect (change in real purchasing power); their interaction determines the slope of demand curves and distinguishes normal from inferior and Giffen goods.

  • expected utility — Expected utility is the quantity that rational agents try to maximize when outcomes are uncertain. It is central to consumer choice and lottery behavior, and it underlies standard models of risk aversion.
    • risk aversion — Risk aversion is the preference for safer payoffs over riskier ones with the same expected value. It is measured by the Arrow-Pratt coefficient and appears in ideas like diversification, precautionary saving, and prospect theory.
      • Arrow-Pratt measure — Risk aversion is the microeconomic preference for safer outcomes over risky ones with the same expected value. Typical clues include concave utility, the Arrow-Pratt measure, diversification, and the Allais and Ellsberg paradoxes.
  • marginal analysis
    • Marginal Benefit — Marginal benefit is the added value or willingness to pay from consuming one more unit of a good or service. It is the benefit side of marginal analysis, often compared directly with marginal cost in economics.
  • Value theory
    • Paradox of value — The paradox of value asks why scarce goods like diamonds are more expensive than useful goods like water. Adam Smith popularized the problem, and the standard explanation contrasts marginal utility with total utility.
      • diamonds and water — Adam Smith’s paradox of value is often illustrated by diamonds and water. The puzzle contrasts use value with exchange value and is later explained by marginal utility.
  • Consumer choice theory
    • budget constraint — A budget constraint is the limit on consumer spending imposed by income and prices. In consumer choice theory, utility maximization is modeled subject to this constraint.
  • consumer theory

    • inferior good — An inferior good is a good whose demand falls as consumer income rises, often because buyers substitute toward higher-quality alternatives. It is contrasted with a normal, or superior, good. Cheap cars are a standard example used in economics classes.

    • Budget constraints
      • budget — A budget is the set of affordable bundles or spending possibilities available to a consumer. In economics, a budget constraint limits choices by available money and helps determine the consumption optimum.

    • complementary goods — Complementary goods are products consumed together, such as bicycles and helmets, so demand for one rises when the price of the other falls. Their indifference curves form right angles, which makes them the opposite of substitutes.

    • complements — Goods consumed together, so demand for one rises when the price of the other falls. Examples include ketchup and french fries. Their indifference curves are typically convex to the origin because the goods work together in consumption.

    • Giffen goods — Giffen goods are inferior goods for which demand rises as price rises, because the income effect outweighs the substitution effect. They are named for the classic bread-and-potatoes examples from economic theory, and experiments on rice, rats, and quinine water are often cited in clues about their existence.

    • Hicksian demand — Hicksian demand is the compensated demand function in consumer theory, defined by minimizing expenditure subject to a fixed utility level. It is contrasted with Marshallian demand, because it removes the income effect, and is tied to the Slutsky equation and the expenditure function by Shephard’s lemma.

    • homotheticity — Homotheticity is a preference property in which expenditure shares do not depend on income, so demand expands proportionally as consumers become wealthier. It is associated with linear Engel curves and with utility representations that are homogeneous of degree one.

    • income effect — The income effect is the change in demand caused by a change in real purchasing power or effective real income. It is one component of the Slutsky decomposition, separated from the substitution effect by the Slutsky equation, and helps explain phenomena such as Giffen goods and the backward-bending labor supply curve.

    • marginal rate of substitution — The marginal rate of substitution is the slope of an indifference curve and measures how much of one good a consumer will give up for another while keeping utility constant. In standard microeconomics it helps describe Hicksian demand and equilibrium behavior against the budget line.

    • perfect complements — Perfect complements are goods consumed in fixed proportions, so the consumer gets no extra benefit from one without the other. Their indifference curves are L-shaped, reflecting an infinite or zero marginal rate of substitution.

    • Shephard’s Lemma — Shephard’s lemma states that Hicksian demand equals the partial derivative of the expenditure function with respect to a good’s price. It is a standard result in consumer theory and cost minimization.

    • utility — Utility is the economic measure of satisfaction or benefit from consuming a good or service. It appears in consumer theory through indifference curves, marginal utility, revealed preference, expected-utility models under risk, and the Hicksian dual demand problem, where utility is held fixed.

      • Diminishing Marginal Utility — Diminishing marginal utility is the principle that each additional unit of a good yields less extra satisfaction than the previous one. It helps explain convex indifference curves and why the added pleasure from another unit of consumption eventually falls.

      • Law of diminishing marginal utility — The law of diminishing marginal utility says that each additional unit of a good usually gives less satisfaction than the previous one. It is a standard microeconomic idea used to explain downward-sloping demand and the shape of indifference curves.

    • utility functions — Utility functions are economic or mathematical representations of preferences that consumers try to maximize. They are often discussed with indifference curves, the von Neumann–Morgenstern axioms, and the classic Cobb-Douglas or Bernoulli examples.
      • Cobb-Douglas preferences — Cobb-Douglas preferences are a homothetic functional form used in economics and are a special case of CES preferences. They are often written as products of variables raised to exponents such as alpha and one minus alpha.
    • Utility maximization — This is the utility-maximization step in consumer theory, where a person chooses the bundle that gives the highest satisfaction subject to a budget constraint. It is the standard optimization problem used to derive demand from preferences and prices.
  • Luxury goods
    • Veblen goods — Veblen goods are luxury goods for which demand rises as price rises because the higher price itself makes them seem more exclusive. The idea is named for Thorstein Veblen and is tied to conspicuous consumption.

  • allocative efficiency — Allocative efficiency occurs when resources are distributed so consumer wants are maximally satisfied, often at the point where price equals marginal cost. It is the welfare side of an optimal market outcome, paired with productive efficiency on the production frontier.

  • welfare economics — Welfare economics studies efficiency, equity, and Pareto optimality in markets and public policy. It is associated with Pigou, Rawls, Sen, the fundamental theorems of welfare economics, and the analysis of externalities and redistribution.

    • Amartya Kumar Sen — Amartya Sen is an Indian economist, philosopher, welfare economist, and social choice theorist known for the capability approach. His work on poverty, famine, welfare economics, and development emphasizes entitlements, freedoms, justice, and the real opportunities people have to live the lives they value, and includes the Liberal Paradox.

    • Dead Weight Loss — Dead weight loss is the loss of total surplus caused by a market distortion such as a tax. It represents unrealized gains from trade that no one captures.

    • deadweight losses — Deadweight losses are inefficiencies created when a market distortion, such as a tariff, prevents mutually beneficial trade from occurring. They are losses in total welfare that are not offset by anyone’s gain.

    • economic efficiency — Economic efficiency is the condition in which resources are allocated or used so that output or welfare cannot be improved without creating some tradeoff. It includes Pareto efficiency, Kaldor-Hicks efficiency, and the related idea of fuel economy in applied settings.

    • economic surplus — Economic surplus is the value created in exchange or production, including consumer surplus, producer surplus, and total surplus. It is central to deadweight loss analysis, welfare economics, and Marxist discussions of surplus value.

    • First Fundamental Theorem of Welfare Economics — The First Fundamental Theorem of Welfare Economics says that competitive markets can produce a Pareto efficient allocation in a private-ownership economy. It is often used as a formal statement of the efficiency of free trade and the invisible-hand result.

    • Kaldor-Hicks efficiency — Kaldor-Hicks efficiency is a welfare-economics standard in which an outcome is efficient if the winners could in theory compensate the losers. It is a weaker criterion than Pareto efficiency because some people may be worse off so long as total gains are large enough to cover the harm.

    • Kaldorian criterion — The Kaldor criterion says a policy improves social welfare if the winners could hypothetically compensate the losers and still be better off. It is a standard potential-compensation test in welfare economics.

    • negative income tax — A negative income tax is a proposed welfare device that supplements the earnings of low-income workers through the tax system. Milton Friedman advocated it as a poverty policy, and Nixon’s administration considered but did not enact it.

    • Pareto efficiency — Pareto efficiency, or Pareto optimality, is the welfare-economics condition in which no alternative allocation or reallocation can make one person better off without making someone else worse off. It is named for the Italian economist and sociologist Vilfredo Pareto, appears in competitive equilibrium and Edgeworth box analysis, often as tangency of indifference curves on the contract curve, and is central to the first welfare theorem. The concept is commonly contrasted with Kaldor-Hicks efficiency and is used in social-choice discussions such as Arrow’s impossibility theorem and Sen’s liberal paradox; deadweight loss is commonly taken as evidence that an allocation is not Pareto efficient.

    • Pareto efficient — A Pareto efficient allocation is one in which no one can be made better off without making someone else worse off. The term is also called Pareto optimum. It is the welfare-economics criterion associated with competitive equilibrium and the edge of the production possibility frontier.

    • Pareto optimum — A Pareto optimum is an allocation in which no one can be made better off without making someone else worse off. The concept is named for the Italian economist Vilfredo Pareto.

    • second best — Second best is the welfare-economics idea that when one Pareto condition fails, the remaining optimality conditions must be revised as well. It underlies the general theory of the second best and the idea of second-best institutions in development economics.

    • universal basic income — Universal basic income is a welfare policy that gives people regular cash payments without means testing. Common clues include Andrew Yang’s Freedom Dividend, Alaska’s Permanent Fund dividend, Milton Friedman’s negative income tax, and pilot programs in Finland and Ontario.
      • Andrew Yang — This businessman and former presidential candidate became known for advocating universal basic income through a proposed monthly “freedom dividend.” He also founded Venture for America and popularized the slogan MATH, short for “Make America Think Harder.”

    • Utilitarian justice — Utilitarian justice is the redistributive economic theory grounded in the utilitarian ideas of Bentham and Mill. It treats marginal utility as the reason money is worth less to the rich than to the poor.

    • welfare — Welfare refers to well-being and is the focus of welfare economics and the welfare state. Clues include Kaldor-Hicks compensation, Amartya Sen’s work, and government programs such as health care and food stamps.
  • Decision theory

    • Allais’ Paradox — Allais’ Paradox is a decision-theory paradox named for Maurice Allais. It concerns people’s inconsistent preferences between certain and uncertain outcomes when probabilities and utilities are framed differently.

    • Rational Choice Theory — Rational choice theory models decision-makers as choosing actions that maximize expected utility from ranked, transitive preferences. It is widely used in economics and political science, though critics have challenged its empirical reach and sociological applications.
      • Rationality — Rationality is the idea of making choices according to reason and a utility-maximizing preference ordering, using available information. In economics it appears in homo economicus, rational choice theory, bounded rationality, satisficing, rational expectations, and market models such as the efficient-market hypothesis; it is also distinguished into procedural and substantive forms of rationality.
        • satisficing — Satisficing is Herbert Simon’s term for choosing the first option that meets an acceptable threshold rather than seeking an optimum. It is a standard idea in bounded rationality and appears in decision theory and game-theoretic approximations.
    • utility theory
      • von Neumann-Morgenstern utility — Von Neumann-Morgenstern utility is the expected-utility framework in decision theory, named for John von Neumann and Oskar Morgenstern. Its axiomatic form is associated with completeness, transitivity, continuity, and independence.
  • consumption theory
    • life-cycle hypothesis — The life-cycle hypothesis says people smooth consumption over time by saving during their working years and spending later. Franco Modigliani is the economist most associated with this model, which is often discussed alongside the permanent income hypothesis.
  • substitution effects
    • Decreases — If the price of tortilla chips rises, the price of salsa decreases in this setup. In the short run, higher interest rates also decrease total consumption.
  • consumption — Consumption is spending on goods and services, the opposite of saving. In economics it is tied to Keynes’s marginal propensity to consume, Friedman’s permanent income hypothesis, and Hall’s random-walk model. Social science clues also point to conspicuous consumption and consumer culture.
    • conspicuous consumption — Conspicuous consumption is the use of luxury goods and spending to display wealth or status. Thorstein Veblen coined the idea in The Theory of the Leisure Class, where he connected it to pecuniary emulation and vicarious leisure.
  • General equilibrium — Léon Walras: all markets in an economy reach equilibrium simultaneously; formalized rigorously by Arrow and Gérard Debreu in the 1950s (Arrow-Debreu model). This is the condition in which supply and demand balance across all markets at once, and it also underlies later dynamic stochastic models in macroeconomics.
    • general equilibrium theory — General equilibrium theory is the economic framework that studies how all markets interact at once, rather than in isolation. It is associated with Walras and Debreu, and with results such as the Sonnenschein-Mantel-Debreu theorem and the welfare theorems.
      • Arrow-Debreu model — The Arrow-Debreu model is a foundational general-equilibrium framework in economics. It treats commodities as distinct by time and place, or other delivery conditions, and is associated with proving existence of Walrasian equilibrium.

    • Leon Walras’s law — Leon Walras’s law says that if all but one market in an economy are in equilibrium, then the remaining market must also be in equilibrium. It is used in macroeconomics as a bookkeeping result about the interdependence of markets.

    • market clearing — Market clearing is the condition in which supply and demand balance so that there is no excess demand or supply. In rational expectations and Walrasian models, equilibrium is often described as markets clearing.

    • Walras’ law — Walras’ law states that the value of excess demand across all markets must sum to zero at positive prices. In general-equilibrium terms, if every market but one is in balance, the remaining market must also be in equilibrium.
  • Invisible hand — Smith’s metaphor: individuals pursuing self-interest are guided, as if by an invisible hand, to promote the public good through market prices. It appears in The Wealth of Nations and The Theory of Moral Sentiments, where Smith describes an unintended social outcome produced by private motives. R. H. Tawney linked it to a providential plan, and Timothy Frye and Andrei Shleifer used it in a Cold War comparison of Warsaw and Moscow.

Production and Costs

• Production and Cost

  • Production function — relates inputs (labor, capital) to output. Marginal product of labor (MPL) diminishes as labor is added to fixed capital (short run).

  • Short run vs long run — in the short run, at least one input (usually capital) is fixed. In the long run, all inputs are variable.

  • Fixed cost / variable cost / total cost — average total cost (ATC) = TC / Q; marginal cost (MC) = dTC/dQ. A firm produces where MC = MR.

  • Economies of scale — ATC falls as output grows (increasing returns to scale). Diseconomies of scale: ATC rises.
    • increasing returns to scale — Increasing returns to scale is the economic idea that expanding production lowers average cost and can create firm-level market power. It is central to models of monopolistic competition, trade, and economic geography. Questions often describe Cobb-Douglas functions whose exponents sum to more than one or mention thick markets and agglomeration. Krugman’s economic geography work is a standard clue.

  • Sunk cost — an already-incurred, irrecoverable cost; should not influence forward-looking decisions (though behaviorally it often does).

  • Shutdown rule — in the short run, a firm shuts down if price < AVC; in the long run, exits if price < ATC.

    • business firms — Business firms are economic organizations that produce and sell goods or services and are central objects of analysis in economics and strategic management. They enter markets when profits are available, and Ronald Coase’s work on the nature of the firm explains their existence as institutions that arise to reduce transaction costs compared with using the market. Later theories examine their internal organization and boundaries.

    • firm — A firm is a business organization that makes production decisions and coordinates economic activity internally. Ronald Coase used the theory of the firm to explain why organizations exist by reducing transaction costs in the market.
  • producer theory
    • Hotelling’s Lemma — Hotelling’s lemma says that differentiating a firm’s profit function with respect to output price gives supply, while differentiation with respect to an input price gives the negative input demand. It is the profit-function analogue of Shephard’s lemma and is named for Harold Hotelling.
  • Production economics

    • Economies of scale — Cost advantages that arise when a firm increases output and lowers average cost per unit. Per-unit cost falls as production volume rises because fixed costs are spread over more output and efficiency improves. The concept is central to natural monopoly and to discussions of increasing returns to scale in microeconomics and urban economics.

    • elasticity of substitution — Elasticity of substitution measures how easily one input can replace another in production, commonly between capital and labor. It is central to Cobb-Douglas, Leontief, CES, and related growth or trade models.

    • Intermediate good — An intermediate good is a product used by one firm to produce another good rather than being sold directly for final consumption. Examples include components and raw materials used in multi-stage production.

    • Marginal Product of Labor — Marginal product of labor is the extra output created by adding one more unit of labor to production. It is the slope of the production function at a point and is often described as the output produced by the last worker.

    • value added — Value added is the economic measure of a firm’s output minus the intermediate goods it purchases from other firms. The same phrase appears in the term value-added tax, common in Canada and much of Europe.

  • Production theory
    • diminishing returns
      • Law of Diminishing Returns — The law of diminishing returns says that in the short run, if one input rises while other inputs are held fixed, output eventually increases by smaller and smaller amounts. It is also called the law of diminishing marginal returns, the law of diminishing marginal productivity, or the law of variable proportions. Economists use it to describe declining marginal gains from additional effort or resources, and it underlies upward-sloping marginal cost curves and the convex shape of the production possibilities frontier. It is associated with Ricardo, Turgot, and Malthus, and also appears in computing as Amdahl’s law.
    • factors of production — Factors of production are the economic inputs used to create output, classically land, labor, and capital. Trade and distribution models treat their endowments as central, and entrepreneurship is sometimes added as a fourth factor.

      • capital — Capital is a factor of production: money or assets that can be invested to generate more wealth. The term also appears in economics and sociology in forms such as human capital, social capital, and cultural capital.

      • capital goods — Capital goods are durable productive assets such as machinery used to make other goods and services. They are central to growth theory and to Austrian economics, where Böhm-Bawerk’s roundaboutness is a standard clue.

      • Capital stock — Capital stock is the accumulated stock of productive equipment, structures, and related assets used in production. It is one of the traditional factors of production alongside land and labor.

      • labor — In economics, labor is the human input to production and one of the classic factors alongside land and capital. Clues about wages, the labor market, matching theory, the backward-bending supply curve, and the tradeoff between work and leisure all point to this term.

      • labor and capital — Labor and capital are the two classic factors of production in neoclassical growth and trade models. They appear together in Cobb-Douglas production functions and in the Solow model of long-run growth.

      • land — Land is a recurring answer in questions about agrarian reform, feudalism, Irish land agitation, and colonial land transfers. Clues may mention the Irish Land League, the Plan of Campaign, the Walking Purchase, patroonships, or feudal fiefs.

      • Resources — Resources are scarce inputs used to accomplish tasks, including land, labor, capital, and other factors of production. Economists study how limited resources are allocated, and Ostrom’s work on commons management addresses how they are governed.

    • isoquants — Isoquants are contour curves showing all combinations of inputs that produce the same level of output. They are used in production theory alongside isocost lines and are often discussed with Cobb-Douglas functions.

    • production functions — Production functions relate inputs such as labor and capital to output, and they are central to models of firm behavior and growth. Common examples include Cobb-Douglas, Leontief, and CES forms, while the Solow model uses them to connect technology and returns to scale.

      • Cobb-Douglas — The Cobb-Douglas form is a doubly eponymous utility and production function used in economics. Its exponents sum to one in the constant-returns version, making output depend on factor inputs raised to fixed elasticities.

      • Cobb-Douglas function — The Cobb-Douglas function is a production function widely used in growth theory and microeconomics. In its constant-returns form, its exponents sum to one and represent output elasticities or expenditure shares.

      • Cobb-Douglas production function — The Cobb-Douglas production function models output as a power product of capital and labor, usually written with parameters for technology and output elasticities. It is a standard tool in microeconomics and growth theory because it often implies constant returns to scale and well-behaved factor shares.

      • constant returns to scale — Constant returns to scale means that multiplying all inputs by a factor multiplies output by the same factor. In Cobb-Douglas production functions, this occurs when the input exponents add to one.

    • production — Production is the economic process of creating goods or services, modeled by tools such as the Cobb-Douglas and Leontief functions. The production possibilities frontier illustrates efficient output combinations given land, labor, capital, and technology.

    • production function — A production function in economics relates inputs such as labor and capital to the output a firm or economy can produce. Common examples include the Cobb-Douglas form and Leontief’s fixed-proportions model.
  • cost curves

    • average total cost curve — The average total cost curve shows total cost per unit of output and is U-shaped in standard introductory economics. Its minimum occurs at the firm’s long-run efficient output, where it is intersected by marginal cost.

    • average variable cost — Average variable cost is the cost of producing each unit after fixed costs are removed. In perfect competition, firms shut down in the short run when price falls below this curve.

    • marginal cost — Marginal cost is the cost of producing one additional unit of output. It is the curve firms compare to marginal revenue when deciding how much to produce, and it intersects average total cost at the minimum of that curve. In microeconomics it also helps explain monopoly pricing, shutdown conditions, and Bertrand competition.

  • Costs

    • average total cost — Average total cost, or ATC, is the cost curve whose minimum is reached at the minimum efficient scale in the long run. In perfect competition, price tends toward the minimum point of this curve as entry drives profits to zero.

    • fixed — A fixed cost is one that does not vary with output, such as rent, salaries, or equipment costs. The same word also describes a currency tied to another currency by a set exchange rate.

    • fixed costs — Fixed costs are business expenses that stay the same regardless of how much is produced. Examples include rent and loan payments, and they can act as a barrier to entry in saturated markets.

    • variable costs — Variable costs are production costs that change with the amount produced. They are contrasted with fixed costs, and their average form is the curve that intersects marginal cost at its minimum.

  • profit — Profit is the surplus a firm earns when total revenue exceeds total cost, and it is maximized where marginal revenue equals marginal cost. In economics it can be discussed as accounting profit or economic profit, with the latter subtracting opportunity cost and often falling to zero in long-run perfect competition.
    • Economic profit — Economic profit is the return above normal profit after accounting for opportunity cost. It equals total revenue minus total cost and can persist only when market power or other distortions are present.
  • cost concepts
    • sunk costs — Sunk costs are expenses that cannot be recovered once incurred. They are central to the sunk cost fallacy, the tendency to keep investing in a failing course of action because of past commitments.
  • Cost theory
    • cost — Cost is the economic quantity that includes fixed, variable, sunk, and opportunity forms. In economics, it appears in shutdown conditions, production choice, and the value of the next-best alternative.
  • cost analysis
    • Break-even point — The break-even point is the sales level where total revenue equals total cost. It marks the threshold at which losses stop and profit begins.
  • income and rent
    • economic rent — Economic rent is income earned from control of a factor of production beyond the cost needed to keep it in use. The term also underlies rent-seeking, a strategy of gaining wealth without creating new wealth, and it appears in Ricardo’s law of rent and Hotelling-style resource models.
  • resource rents
    • rents — Rents are payments for the use of land, capital, or other scarce resources, and public choice theory also uses the word for unearned gains sought through regulation or privilege. In modern political debate, rent control refers to laws that cap how quickly apartment rents can rise.
• principal-agent theory
  • Agent — An agent is a decision-maker who acts on behalf of or in relation to another party in a principal-agent setting. In economics and contract theory, the term is central to signaling problems and information asymmetry.

Related Concepts and Applications

• Factor markets
  • labor markets — Labor markets are the factor markets in which workers supply labor and firms demand it. They are analyzed with search-and-matching models, monopsony theory, and compensating differentials.
• Fees and charges
  • tolls — Tolls are charges collected for travel or passage, especially on roads, bridges, ferries, or waterways. They were a major grievance against medieval robber barons and also appeared in the Danish Sound Dues.
• goods and services
  • commodity — A commodity is a good produced by human labor for the market and satisfying human wants. In older literary usage, the word can also mean an acquisitive bias or appetite for gain.
• microeconomics — Microeconomics studies the choices of individuals and firms, along with prices, incentives, utility, and market structure. It contrasts with macroeconomics and is central to topics like elasticity and consumer behavior.
  • Consumer behavior
    • substitute — A substitute is a good that can replace another good in consumption. In economics, substitute goods move in the same direction in demand when relative prices change, and they help define cross-price elasticity.
  • consumer choice theory
    • substitution effect — The substitution effect is the change in consumption caused by a price change that makes a consumer switch from one good to a relatively cheaper alternative. It is separated from the income effect in the Slutsky decomposition and is central to discussions of Hicksian demand and Giffen goods.
  • Consumer goods
    • Durable good — A durable good is a consumer product that lasts for more than one use, such as a car or a piano. Economists watch demand for durable goods closely because purchases of them are often delayed during recessions.
  • Consumer theory
    • Slutsky equation — The Slutsky equation is the microeconomic formula that separates a price change’s total effect on demand into substitution and income effects. It connects compensated, or Hicksian, demand with uncompensated, or Marshallian, demand and is used in consumer theory to analyze how consumers respond to price changes.
      • Eugen Slutsky — Eugen Slutsky was a Russian economist and statistician known for the Slutsky equation. His work connected price changes to income and substitution effects in consumer demand theory.
    • Utility function — A utility function in economics represents a consumer’s preferences over bundles of goods. It is central to choice theory and expected utility, and it is maximized by rational agents under budget constraints.

  • contract curve — The contract curve is the set of Pareto-efficient allocations in an Edgeworth box, where the indifference curves of two parties are tangent. It marks the outcomes from which no further mutually beneficial trade is possible.

  • Cross price elasticity of demand — Cross-price elasticity of demand measures how the quantity demanded of one good changes when the price of another good changes. It is typically negative for complements and positive for substitutes.

  • Demand — Demand describes consumers’ willingness to purchase a good at different prices. The ordinary demand curve slopes downward, and income changes can alter purchasing behavior through the income effect. In labor markets, firms supply the demand for workers, reversing the household-as-buyer pattern of many product markets.

    • A Giffen good — A Giffen good is a type of inferior good whose demand can rise when its price rises, producing an upward-sloping demand curve. It is a standard economics example used to show an exception to the usual law of demand.

    • demand decreases — Demand decreases when the quantity demanded falls in response to a change such as a higher price for a complement or a drop in consumer demand. It is one side of the basic supply-and-demand framework used in economics.

    • Hicksian demand curve — The Hicksian demand curve shows the relationship between price and quantity demanded at a fixed utility level. It isolates the substitution effect and is always downward-sloping.

    • Law of Demand — The law of demand states that quantity demanded generally falls when price rises and rises when price falls. Veblen goods are a standard exception because higher prices can increase their desirability.

    • Perfect inelasticity — Perfectly inelastic demand does not change when price changes, giving it a vertical demand curve. Economists use the term for goods whose quantity demanded stays fixed no matter the price.

  • demand curves
    • Engel curve — An Engel curve plots the amount of a good consumed against income, showing how spending changes as households get richer or poorer. It is used in microeconomics to study normal and inferior goods and household budget allocation.
  • Demand theory

    • Giffen paradox — A purported exception to the law of demand in which quantity demanded rises as price rises. It is usually explained by staple goods for very poor consumers, where a price increase can force them to spend more on the staple and less on substitutes; examples include bread or potatoes.

    • price elasticity of demand — Price elasticity of demand measures how responsive quantity demanded is to a change in price. It is central to topics like the Marshall-Lerner condition, the Lerner index, and the distinction between elastic and inelastic demand.

  • diamond-water paradox — The diamond-water paradox is the apparent contradiction that water is more useful while diamonds are more valuable in exchange. It is explained by marginal utility rather than total utility.

  • envelope theorem — The envelope theorem says that the derivative of a maximized value function can be found by evaluating the partial derivative at the optimum. It is used in microeconomics and in results such as Hotelling’s lemma.

  • Equilibrium Point — The equilibrium point is the market price at which supply and demand intersect. It is also used more broadly in economics and chemistry to describe a balanced state where opposing forces or curves meet.

  • Expected utility theory
    • Maurice Allais — Maurice Allais was a French economist and Nobel laureate known for the Allais paradox, which challenges expected-utility theory. He also worked on overlapping generations models and is associated with the Allais effect in physics.
  • firm production
    • shutdown point — A shutdown point is the output level at which a firm should stop producing in the short run because price has fallen to the minimum of average variable cost. Below this point, continuing production would not cover variable costs.
  • income — Income is the money earned over a period of time, and in economics it appears in demand theory, Engel curves, and the income effect. It also matters in inequality discussions, including the Great Gatsby curve and studies of labor versus capital income.
    • Disposable income — Disposable income is the amount of income left after taxes and payroll deductions, often called take-home pay. Economists use it to describe what households can spend or save after government claims have been removed.

  • indifference curve — An indifference curve shows combinations of goods that yield the same level of utility to a consumer. In microeconomics it is usually downward-sloping and convex, reflecting bundles over which the consumer has no preference.

  • Information economics
    • The Market for Lemons — The Market for Lemons is George Akerlof’s classic paper on adverse selection, using the used-car market to show how information asymmetry can drive good goods from the market. Its title refers to “lemons,” the slang term for defective used cars.
  • Marginal analysis
    • marginal — Marginal describes a small incremental change, especially in economics and game theory. Common uses include marginal cost, marginal revenue, marginal utility, and the marginal rate of substitution or technical substitution. Quizbowl clues often point to the marginal revolution in economics and to the idea of reasoning at the margin. The adjective also appears in phrases for incremental analysis of cost, benefit, and contribution.
  • Market structure
    • bilateral monopoly — A bilateral monopoly is a market in which one seller faces one buyer, combining monopoly power on the selling side with monopsony power on the buying side. The term is also used by analogy for situations such as labor bargaining between a union and an employer.
  • Opportunity cost — Opportunity cost is the value of the next-best alternative foregone when a choice is made. It underlies comparative advantage and the idea that even a free lunch is not truly free, because scarce resources could have been used elsewhere.

    • Free lunch — Free lunch is the idea that even when something looks costless, the next-best alternative still has an economic cost. Economists use it to illustrate opportunity cost, especially in comparisons to accounting profit, comparative advantage, and the broken window fallacy. The phrase is what the slogan TANSTAAFL, or “There ain’t no such thing as a free lunch,” denies, emphasizing that benefits come with some price.

    • Opportunity — Opportunity can mean a chance or advantageous possibility, and in economics it appears in the phrase opportunity cost. It is also the name of NASA’s Mars rover, the twin of Spirit, which explored craters such as Victoria and Endeavour.

    • opportunity costs — Opportunity costs are the value of the next best alternative forgone when a choice is made. They are central to comparative advantage, economic trade-offs, and the distinction between accounting and economic profit.

  • production possibilities frontier — The production possibilities frontier is the curve showing the maximum feasible output combinations of two goods an economy can produce with fixed resources and technology. Its slope reflects opportunity cost, often described as the marginal rate of transformation, and its concave shape reflects increasing opportunity costs. Points on the curve are efficient, points inside it indicate underutilized resources, and points outside it are unattainable. It is often illustrated with the classic guns-versus-butter tradeoff.
    • marginal rate of transformation — The marginal rate of transformation is the slope of the production possibilities frontier, showing how much of one output must be given up to produce more of another. The curve is used to model tradeoffs such as guns versus butter and to distinguish feasible from unattainable output combinations.
  • Production theory

    • expansion path — The expansion path is the locus of tangency points between isoquants and isocost lines in production theory. It traces the cost-minimizing input combinations as output changes, and is the production-side analogue of the income-consumption curve.

    • isoquant — An isoquant is a curve showing combinations of inputs, such as labor and capital, that produce the same level of output. It is the producer’s analogue of an indifference curve; its slope reflects the marginal rate of technical substitution, and its tangency with an isocost line gives the cost-minimizing input bundle.

  • profit maximization
    • marginal revenue and marginal cost — Firms maximize profit by producing where marginal revenue equals marginal cost. That condition is central to both perfect competition and monopoly, though monopoly pricing can create deadweight loss.

  • Substitutes — Substitute goods are goods that can be used in place of one another, so demand for one rises when the price of the other rises; they have positive cross-price elasticity. Examples include butter and margarine or CDs and MP3s. In microeconomics, the substitution effect describes how consumers shift toward relatively cheaper alternatives when prices change, in contrast to complements. The term also appears in business strategy, where Porter’s five forces includes the threat posed by substitutes.

  • surplus — A surplus is a situation in which revenue exceeds spending, or more generally when supply or income exceeds demand or cost. In government finance it contrasts with a deficit, and in economics it can refer to consumer or economic surplus.

  • x-inefficiency — X-inefficiency is the gap in a firm between actual production costs and the lowest possible costs for that output. It is usually associated with monopolies and other settings with weak competitive pressure.
• Core economics concepts
  • scarcity — Scarcity is the basic economic problem created by unlimited wants and limited resources. It is central to discussions of post-scarcity economics and steady-state theory.
    • There Ain’t No Such Thing As A Free Lunch — TANSTAAFL is the acronym for ‘There Ain’t No Such Thing As A Free Lunch,’ a phrase popularized by Robert Heinlein. It is often used to express the idea that every benefit has a cost, even when that cost is hidden or indirect.
• economic goods
  • goods — Goods are products or services that provide utility or satisfaction in economics. Examples include public goods such as national defense, private goods such as clothing and cars, and substitutes that can replace each other when prices change.
    • inferior goods — Inferior goods are goods whose demand falls as income rises, giving them negative income elasticity. A Giffen good is a special kind of inferior good whose demand can rise when its price rises, and examples often include cheap substitutes like instant noodles or bus travel.

• endowments — Endowments are the initial resources, assets, or factor supplies with which a person or economy begins. In Mormon usage, the word can also refer to a ceremonial rite described as a gift from God.

• Exchange
  • barter system — This is the direct exchange of goods for goods, usually requiring a coincidence of wants. Economists such as Adam Smith, William Stanley Jevons, and Caroline Humphrey are cited in debates over whether it ever existed as a general pre-monetary system.
• scarcity management
  • rationing — Rationing is a system of limiting purchases and distributing scarce goods during shortages. It was used for food, fuel, and other commodities in wartime Britain, the United States, Israel, and elsewhere.
• consumers — Consumers are the buyers of goods and services, and the National Consumers League was founded to expose abuses that harmed them. The clue set also gestures toward Consumer Reports and Consumers Union, organizations aimed at informing shoppers.

Market Structures

• Competition, Monopoly, and Oligopoly

  • Perfect competition — homogeneous product, free entry/exit, perfect information. Equilibrium: P = MC = ATC (long run). It also assumes many buyers and sellers, firms as price-takers, and no single seller’s power over price; long-run economic profit disappears.

  • Duopoly — a market structure in which exactly two sellers (or buyers, in a duopsony) dominate the market; a special case of oligopoly; analyzed using Cournot, Bertrand, and Stackelberg models; real-world examples include commercial aircraft (Airbus/Boeing) and some regional telecommunications markets.

  • Monopoly — sets MR = MC, then charges the demand curve price; produces less at higher price than competitive market. Deadweight loss quantifies inefficiency. A monopoly is a market structure with a single seller and high barriers to entry. It is associated with pricing above marginal cost, deadweight loss, and measures such as the Herfindahl-Hirschman Index reaching its maximum value.
    • Pure monopoly — A pure monopoly is a market structure with a single seller of a product that has no close substitutes. It is the starkest form of monopoly in standard market-structure classification.

  • Natural monopoly — ATC declines over the entire relevant output range; a single firm serves the market more cheaply than multiple firms. Regulated via average-cost pricing or marginal-cost pricing.

  • Oligopoly — strategic interdependence; analyzed with game theory. Models include Cournot (quantity competition), Bertrand (price competition), and Stackelberg (sequential leadership). An oligopoly is a market structure dominated by a small number of firms. Firms are interdependent, often face high barriers to entry, and may collude as a cartel; a duopoly is a limiting case.

    • Cournot competition — Cournot competition is an oligopoly model, named after Antoine Augustin Cournot, in which firms choose output independently and simultaneously rather than setting prices. In the duopoly version, each firm chooses a quantity while assuming rivals keep output fixed; the model is associated with reaction functions and residual demand, is a standard example of strategic competition among firms producing homogeneous goods with market power, and approaches perfect competition as the number of firms grows large. It is contrasted with Stackelberg competition, where a leader moves first.

    • Cournot Duopoly — A Cournot duopoly is a model in which two firms choose quantities simultaneously while each anticipating the other’s best response. The outcome lies between perfect competition and monopoly in both price and output. The model is named for the French economist Augustin Cournot.

    • kinked demand curve — A kinked demand curve is the oligopoly model in which firms are expected to match price decreases but not price increases. It is often described as having a bend that creates a discontinuity in marginal revenue and helps explain price rigidity.

    • oligopolies — An oligopoly is a market structure dominated by a small number of firms or sellers. Models of oligopoly include Cournot and Stackelberg competition, and the field often studies strategic interaction among firms.

    • price wars
      • Price war — A price war occurs when competing firms repeatedly undercut one another, causing prices to fall across an oligopoly. It is usually a temporary escalation of competitive discounting rather than a stable long-term equilibrium.
    • Stackelberg Duopoly — The Stackelberg duopoly is an oligopoly model with sequential moves, unlike simultaneous-choice Cournot competition. In the usual version, one firm acts first and the other responds after observing that decision.

  • Monopolistic competition — many firms sell differentiated products; entry drives economic profit to zero; firms operate on the downward-sloping part of ATC (excess capacity).

  • Market structure

    • cartel — A cartel is a group of firms or organizations that collude, often to keep prices high in an oligopoly. The word is also used for drug-trafficking syndicates such as the Sinaloa cartel and for associations like OPEC.

    • market power — Market power is a firm’s ability to influence price rather than simply accept the market price. It is associated with monopoly behavior, the Lerner index, and the ability to raise markups in concentrated markets.

    • monopolies — Monopolies are market structures with a single producer or supplier, often associated with high prices, restricted output, and market power. They are a classic target of antitrust policy, and related clues may mention natural monopolies, price discrimination, or firms such as Standard Oil and utilities.

    • monopolistic competition — Monopolistic competition is a market structure with many firms selling differentiated products and facing downward-sloping demand. Entry drives long-run profits to zero, so firms retain only limited market power; restaurant markets and the Dixit-Stiglitz model are standard examples.

    • monopsony — Monopsony is a market structure with one buyer and many sellers, often used in economics to model labor markets and employer power. It is associated with upward-sloping labor supply, marginal expenditure, and cases where minimum wages can raise employment.

      • Monopsony power — Monopsony power is the bargaining power a single buyer can exert in a market. It is associated with upward-sloping factor supply curves, such as wage-setting by dominant employers.

      • There are many sellers and one buyer. An example is the diamond — The market system described as having many sellers and one buyer is monopsony. A diamond market is a classic example of this buyer-side market structure.

  • industrial organization

    • Bertrand model — The Bertrand model describes price competition in a duopoly, where firms choose prices rather than quantities. Its standard result is a competitive equilibrium at marginal cost, with Edgeworth’s extension and Hotelling’s critique appearing in related discussions.

    • Antitrust
      • the consumer welfare standard — The consumer welfare standard is the antitrust principle associated with Robert Bork that judges mergers by their effects on consumer prices, output, quality, or allocative efficiency. Critics argue that it lets too many anticompetitive mergers survive, especially in cases involving large technology firms.

    • barriers to entry — Barriers to entry are obstacles that make it hard for new firms to enter a market, such as capital requirements or economies of scale. Economists distinguish structural barriers from strategic ones, and Porter’s five forces uses the threat of new entrants to describe their effect.

    • Cartels — Cartels are collusive groups of firms or producers that coordinate prices, output, or wages to increase profits and gain market control. They are often associated with oligopoly power. OPEC is the standard example, and other coordinated producer groups are also cited as examples.
      • a pool — A pool is a body of water, but it can also refer to a cartel-style arrangement in which competitors fix prices or divide markets. The term also fits the elaborate water setting used in Busby Berkeley’s Footlight Parade.
    • Collusion — Collusion is a secret agreement among rivals, often used in law and economics for practices like price fixing or cartel behavior. Quizbowl clues may point to Major League Baseball salary suppression disputes in the 1980s.
      • Price fixing — Price fixing is an illegal form of collusion in which firms agree to raise, lower, or stabilize prices rather than compete. Related forms include resale price maintenance and bid rigging, which distort consumer surplus and market competition.
    • Monopoly power
      • Lerner index — The Lerner index measures monopoly power by comparing price and marginal cost relative to price. It is zero under perfect competition and rises as a firm gains more market power.
    • network effects — Network effects are situations in which a product or service becomes more valuable as more people use it. They are central to platforms, standards, and communication networks, and their negative form is congestion. These effects also appear in new trade theory and in two-sided markets such as ride-sharing, social media, and software ecosystems. Economists often contrast direct and indirect network effects when discussing lock-in and adoption.
  • Monopolies and trusts
    • Standard Oil Company — Standard Oil Company was John D. Rockefeller’s petroleum monopoly, later broken up under antitrust law. Ida Tarbell’s muckraking history exposed its practices, and it became a symbol of trusts, rebates, and early corporate consolidation.
  • monopoly contracts
    • asiento — An asiento was a Spanish monopoly contract, often granted for importing goods or slaves into colonial markets. The Treaty of Utrecht gave Britain the lucrative asiento to supply enslaved Africans to Spanish America.
  • Pricing strategy
    • predatory pricing — Predatory pricing is the practice of selling below cost to drive rivals out of the market. It is often discussed in antitrust contexts and can be associated with the idea of using a large financial reserve to outlast competitors.
  • Market concentration

    • concentration ratio — The concentration ratio measures how much of an industry’s output is controlled by its largest firms. It is a standard way to describe market concentration in economics, with the Herfindahl index often mentioned as a related measure.

    • Herfindahl-Hirschman Index — The Herfindahl-Hirschman Index measures market concentration by summing the squares of firms’ market shares. It is widely used in antitrust and merger analysis, with higher values indicating more concentrated markets and helping regulators distinguish competitive markets from concentrated ones or monopolies.

  • Oligopoly models
    • Bertrand duopoly — A Bertrand duopoly is a model in which competing firms choose prices simultaneously. It is associated with the prediction that price competition can drive profits down, especially when products are similar and customers buy from the cheaper seller.
  • Price discrimination — first degree: charge each consumer their exact willingness to pay. Second degree: quantity discounts, versioning. Third degree: different prices to different market segments (e.g., student discounts). Commonly described by Pigou’s three degrees: first-degree price discrimination charges each consumer their exact willingness to pay, second-degree uses quantity discounts and versioning, and third-degree charges different market segments different prices, such as student discounts. Joan Robinson also classified market forms by price discrimination, and the Robinson-Patman Act is associated with regulating it.

    • First-degree price discrimination — First-degree price discrimination is the case where a seller charges each buyer the highest price that buyer is willing to pay. By capturing all consumer surplus, it lets a monopolist maximize profit.

    • Second-degree price discrimination — Second-degree price discrimination occurs when a firm offers different prices based on the quantity or contract terms chosen by the buyer. Airline advance-purchase fares and bulk discounts like a cheaper six-pack than six individual cans are standard examples.

Game Theory

• Game theory

  • Bayesian games — Bayesian games are games of incomplete information in which players are uncertain about others’ types, payoffs, or strategies. They are analyzed using probability beliefs, a framework developed in part by John Harsanyi.

  • focal points — Focal points, or Schelling points, are salient solutions people gravitate toward when they must coordinate without communication. Thomas Schelling popularized the idea with examples like meeting at Grand Central Station in New York City.

  • folk theorem — The folk theorem in game theory says many payoff outcomes can be sustained as equilibria in infinitely repeated games. It characterizes feasible, individually rational outcomes that can be enforced by threat of punishment or trigger strategies.

  • incomplete information — Incomplete information is the game-theory property in which players do not know one another’s payoffs or types. It is associated with Bayesian games and with the Harsanyi transformation.

  • Reinhard Selten — Reinhard Selten was a German game theorist who shared the 1994 Nobel Prize in Economics with John Nash and John Harsanyi. He is also known for work on subgame perfection and for the chain store paradox.

  • Bayesian game — A Bayesian game is a game-theory model in which players have incomplete information about one another’s types or actions and update beliefs as the game proceeds. It is named for Thomas Bayes.

  • Bayesian-Nash equilibrium — A Bayesian-Nash equilibrium is a game-theory solution concept for situations with incomplete information. It extends Nash equilibrium by incorporating beliefs about other players’ types, and the revelation principle is often used to analyze it.

  • beauty contest — A beauty contest is a nonviolent competition, mythically exemplified by the Judgment of Paris and other contests judged by appearance. In economics, the term also appears in Keynes’s beauty-contest analogy, where success depends on guessing what others will choose.

  • burning money — Burning money is the deliberate destruction of currency, most famously associated with the K Foundation’s 1994 performance at a boathouse in the Inner Hebrides. It also appears in game theory as a commitment device because destroying resources can change strategic incentives.

  • cooperation — Cooperation is collective behavior in which agents work together rather than defect, as in the prisoner’s dilemma and coalition-building games. It titles Robert Axelrod’s study of tit-for-tat and Peter Kropotkin’s Mutual Aid, and it is often analyzed in game theory and institutionalism.

  • dictator game — The dictator game is a behavioral economics experiment in which one participant chooses how much of an endowment to give another participant, who must accept the result. It is used to study fairness and altruism because the sender faces no punishment for keeping everything.

  • Dollar auction — The dollar auction is Martin Shubik’s escalation game in which the highest bidder wins but the second-highest bidder still pays. It is often used to illustrate how rational players can trap themselves in a loss-minimizing bidding war.

  • iterated games
    • iterated — Iterated, or repeated, games are played over multiple rounds rather than once. In game theory, this setting allows strategies such as tit-for-tat and grim trigger, and it also appears in iterated elimination of dominated strategies.

  • John Harsanyi — John Harsanyi was a Hungarian-American game theorist and Nobel laureate who helped analyze bargaining, equilibrium selection, and expected utility under uncertainty. His work on the original position influenced later ideas about bargaining and Rawls’s veil of ignorance.

  • Mechanism design — Mechanism design is a field of economics and game theory devoted to designing rules and incentives so that agents reveal private information truthfully. Its core results include the revelation principle, the Myerson-Satterthwaite theorem, and work by Hurwicz, Maskin, and Myerson.
    • auctions — Auctions are sales mechanisms in which buyers compete by bidding for goods or services. They are studied in mechanism design for how auction rules shape outcomes and include English, Dutch, blind, sealed-bid, Vickrey, and VCG formats. The winner’s curse describes how the winning bidder may overpay.

      • Dutch auction — A Dutch auction is a descending-price sale in which the seller starts high and lowers the price until a buyer accepts. It is used in some IPOs and stock buybacks, and it is also associated with flower auctions such as Aalsmeer.

      • English auction — An English auction is an ascending, open auction in which bidders successively raise the price until only one bidder remains. The highest bidder wins and pays the final bid, making this the most common auction format in practice.

      • truthful bid — In a Vickrey auction, the optimal bid is to state exactly your true valuation of the item. This strategy is optimal because the winner pays the second-highest bid rather than their own bid.

    • Myerson-Satterthwaite theorem — The Myerson-Satterthwaite theorem shows that two parties with private valuations cannot always be made to trade efficiently under asymmetric information. It is a foundational impossibility result in mechanism design and bilateral bargaining.

  • mixed strategies — Mixed strategies are game-theoretic strategies in which players randomize among pure strategies using probabilities. They are essential when no pure-strategy Nash equilibrium exists. They are especially common in zero-sum games, where each player chooses a randomized mix to keep the opponent indifferent.

  • multiple equilibria — Multiple equilibria occur when a game or economic model has more than one stable outcome consistent with everyone’s best responses. The concept is central to coordination problems, bank-run models, and Thomas Schelling’s discussion of focal points.

  • Nash equilibrium — A game-theoretic outcome in which no player can improve by changing strategy alone. Existence results are associated with fixed-point theorems, and refinements include subgame-perfect equilibria for dynamic games. It also appears in discussions of general equilibrium and Pareto optimality in economics.

  • perfect information — Perfect information is the property of a game in which all players know the current state and the full sequence of prior moves. It applies to combinatorial games such as chess and tic-tac-toe.
    • perfect — In game theory and economics, perfect describes equilibrium and information concepts such as subgame perfection, perfect information, and perfect competition. These ideas appear in discussions of sequential rationality, backward induction, and market efficiency.

  • risk dominance — Risk dominance is a refinement of Nash equilibrium introduced by John Harsanyi and Reinhard Selten. A strategy is risk-dominant when it has the larger basin of attraction and performs better against mutations or irrational opponents.

  • Shapley value — The Shapley value is a cooperative game theory solution concept that assigns each player a share based on marginal contribution across all coalition orders. It is characterized by axioms and was introduced by Lloyd Shapley in 1953.

  • strategies
    • tit-for-tat — Tit-for-tat is the iterated prisoner’s dilemma strategy that begins by cooperating and then copies the opponent’s previous move. Anatol Rapoport developed it, and Robert Axelrod’s tournaments made it famous as a simple, nice, and forgiving strategy.

  • subgame perfect Nash equilibrium — A subgame perfect Nash equilibrium is a strategy profile that remains a Nash equilibrium in every subgame of an extensive-form game. It is typically found by backward induction and rules out noncredible threats in perfect-information settings.

  • tit for tat strategy — Tit for tat is the classic iterated prisoner’s dilemma strategy that begins by cooperating and then simply copies the opponent’s previous move. It was associated with Anatol Rapoport and is often discussed alongside grim trigger as a simple reciprocity rule.

  • zero-sum — A zero-sum game is one in which one participant’s gain is exactly balanced by another’s loss. In such games, the total payoff at the end is zero.

  • Zero-sum game — A zero-sum game is one in which one player’s gain is exactly balanced by another player’s loss. Game theory’s minimax theorem and the prisoner’s dilemma are often discussed against this background, though the latter is not actually zero-sum.

  • zero-sum games — Zero-sum games are strategic situations in which one player’s gain is exactly another player’s loss. They include examples such as Matching Pennies and other constant-sum contests where the total payoff stays fixed.
• Games, Strategy, and Equilibrium

  • Prisoner’s dilemma — two players each have a dominant strategy that leads to a mutually worse outcome than cooperation. The Nash equilibrium is (defect, defect). It is commonly framed as two suspects deciding whether to stay silent or betray each other, and is a standard non-zero-sum game used to study cooperation and conflict. Its payoff ordering is typically T > R > P > S, and the iterated version is often analyzed with strategies such as tit-for-tat, associated with Robert Axelrod. The game was formalized by Merrill Flood, Melvin Dresher, and Albert Tucker.

  • Nash equilibrium — a strategy profile in which no player can improve their payoff by unilaterally changing strategy. Named for John Nash; formalized 1950.

  • Dominant strategy — a strategy that is best regardless of the other player’s action. In prisoner’s dilemma examples, defection is the classic dominant strategy, and in Vickrey-Clarke-Groves settings truth-telling can also be dominant.

  • Repeated games — repeated interaction can sustain cooperation that a one-shot game cannot; tit-for-tat is a notable cooperative strategy in iterated prisoner’s dilemmas (Axelrod tournaments).

    • grim trigger — The grim trigger is a game-theoretic strategy in repeated prisoner’s dilemma play. It begins with cooperation but switches permanently to defection after the other player defects once.

    • iterated prisoner’s dilemma — The iterated prisoner’s dilemma is the repeated game in which players choose whether to cooperate or defect over many rounds. It is associated with Axelrod’s tournament, Rapaport’s tit-for-tat, and other strategies designed to encourage cooperation.

  • Coordination game — players prefer to choose the same strategy; multiple Nash equilibria possible. Example: driving on the left vs right. Classic examples include battle of the sexes and Schelling-point reasoning, and failures of coordination can leave everyone stuck at a worse equilibrium.

  • Minimax theorem — John von Neumann (1928): in zero-sum two-player games, the strategy that minimizes the maximum loss (minimax) equals the strategy that maximizes the minimum gain (maximin); foundational result of game theory. It is John von Neumann’s foundational result in game theory for two-player zero-sum games. It says that an optimal strategy exists in which minimizing the maximum loss is equivalent to maximizing the minimum gain.

  • Backward induction — in extensive-form games, solving from the last move backward to determine the subgame perfect Nash equilibrium; central to sequential game analysis. It is used for finite extensive-form games, yielding subgame perfect Nash equilibria, and appears in analyses such as the centipede game and Stackelberg competition.

  • bargaining theory
    • bargaining — Bargaining is the process of negotiating agreement over prices, wages, or other terms, and it underlies collective bargaining in labor relations. It is also the basis of the Nash bargaining problem and appears in arguments about how low transaction costs can reduce conflict.
• Auctions and Market Design
  • Auction theory — studies optimal bidding and auction design; key results include the revenue equivalence theorem (standard auctions yield equal expected revenue under symmetric conditions); associated with William Vickrey and Roger Myerson.

    • Vickrey auction — A Vickrey auction is a sealed-bid mechanism in which the highest bidder wins but pays the second-highest bid. It is a truthful auction design associated with William Vickrey and often generalized to multi-item settings such as the VCG mechanism.

    • William Spencer Vickrey — William Spencer Vickrey was an economist known for auction theory, including the sealed-bid second-price auction that bears his name. He also worked on congestion pricing. His name appears in the Vickrey-Clarke-Groves mechanism, which is designed to be dominant-strategy incentive compatible.

    • Winner’s curse — The winner’s curse is the situation in which the highest bidder in an auction tends to pay more than an item is worth. It is often discussed in microeconomics as a problem that arises when bidders’ estimates are roughly accurate but competitive bidding pushes the price above value.

  • Vickrey auction (second-price sealed-bid) — bidders submit sealed bids; the highest bidder wins but pays the second-highest bid; the dominant strategy is to bid one’s true valuation (strategy-proof).

  • Market design
    • matching — Matching is the general economics and market-design process of pairing agents with jobs, schools, spouses, or other partners under rules like the Gale-Shapley algorithm. The topic also includes stable matching, residency assignment, and other mechanisms studied by Roth, Shapley, and related search-and-matching models.

Information, Incentives, and Social Choice

Build from markets and strategic interaction to asymmetric information, incentive design, and collective choice.

• Lemons problem — George Akerlof’s 1970 model: in a used-car market, sellers know quality but buyers don’t; adverse selection can collapse markets entirely when only “lemons” (low-quality goods) remain; foundational to information economics.

• Signaling (Spence) — Michael Spence: high-type workers obtain costly credentials (education) to credibly signal unobservable quality to employers, even if the credential adds no productive skill.

• Principal-agent problem — the agent (employee, manager) has different interests and private information compared to the principal (employer, shareholder); mitigated by incentive contracts, monitoring, and bonding. The same model is used in political science and other social-science settings where authority is delegated to an agent whose information or incentives differ from the principal’s, creating moral hazard and asymmetric-information problems in firms, law, politics, and committees. Monitoring, transparency, professional norms, and overlapping oversight can reduce but not eliminate the gap.
  • principal
    • The Principal — In economics, the principal is the party that delegates authority to an agent, as in the principal-agent problem. The concept is used to model situations where a manager acts on behalf of shareholders. The same term also names the law of superposition in archaeology, which says lower layers are generally older than layers above them. That principle underlies stratigraphy and relative dating. The Principal is also the title of a 1987 film about a teacher named Rick Latimer, played by James Belushi.

• Moral hazard — a party takes greater risks because someone else bears the cost (e.g., insured driver; bailed-out bank). It is a principal-agent problem often discussed in insurance and corporate incentives, and it is distinct from adverse selection.

• Adverse selection — before a transaction, one party has private information leading to a skewed pool (e.g., “lemons” in used-car markets; Akerlof 1970). It commonly arises in insurance and labor markets; related responses include signaling by informed parties and screening by uninformed ones.

• Arrow impossibility theorem — Kenneth Arrow (1951): no ranked voting system can simultaneously satisfy unanimity, independence of irrelevant alternatives, and non-dictatorship when there are three or more options; foundational result in social choice theory.

• Asymmetric information — Akerlof (lemons), Spence (signaling), Stiglitz (screening) shared the 2001 Nobel for foundational work. It is a market failure in which one side of a transaction knows more than the other, as in George Akerlof’s used-car example in The Market for Lemons. It underlies adverse selection, moral hazard, signaling, and screening in economics.

• Moral hazard / adverse selection — post-contract and pre-contract information problems, respectively (see Market Failures above).

• Social choice theory — Social choice theory studies how individual preferences are aggregated into collective decisions. It is associated with Kenneth Arrow and with attempts to give economics a rigorous account of voting, welfare, and social welfare functions.

• Information economics

  • credence goods — Credence goods are products whose quality cannot be easily evaluated by consumers even after purchase. Classic examples include prescription medicine and mechanic-recommended repairs, where information asymmetry makes the seller or expert especially important.

  • signaling — Signaling is the strategy of sending costly or credible information to reduce problems caused by information asymmetry. In economics it appears in job-market education credentials, while in biology and cell biology it also names the communication process by which cells transmit information.
    • Andrew Michael Spence — Andrew Michael Spence is the economist best known for labor-market signaling, especially the idea that education can function as a signal of worker ability rather than pure productive skill. His work won the 2001 Nobel Prize in Economics alongside George Akerlof and Joseph Stiglitz.

  • asymmetrical information — Asymmetrical information describes situations in which one side of a transaction knows more than the other. George Akerlof’s used-car example, along with the work of Spence and Stiglitz, is a standard illustration of the idea.

  • information — Information is the commodity whose asymmetries create problems like adverse selection and moral hazard in economics, and it is also the quantity central to Shannon’s information theory. Quizbowl clues often mention asymmetric information, signaling, the market for lemons, and entropy measured in bits.

  • market for lemons
    • lemons — A lemon is a fruit whose name is also slang for a defective car, a meaning made famous by George Akerlof’s paper on the market for lemons. Quiz clues may also invoke Felicity Lemon from Hercule Poirot or Liz Lemon from 30 Rock. The fruit name can also turn up in jokes about sour or disappointing things.

  • signalling — Signalling in economics is the transmission of information through observable actions or investments when information is incomplete. Michael Spence’s job-market model explains education as a signal, and the idea also appears in international relations and market design.

  • signals — Signals are actions or messages used to convey information, especially in game theory and economics. They can be used to reveal type, reduce information asymmetry, and distinguish separating from pooling equilibria.

  • used cars — George Akerlof’s Market for Lemons uses used cars as a classic example of how information asymmetry can create adverse selection. Robert Cialdini’s work on persuasion also draws on used-car sales and related tactics such as the low-ball technique and anchoring.

Behavioral Economics and Decision-Making

Compare standard choice models with loss aversion, framing, discounting, and choice architecture.

• Endowment effect — Richard Thaler: people demand more to give up an object than they would pay to acquire it; a form of loss aversion that violates standard preference theory.

• Loss aversion — Kahneman-Tversky finding: the pain of a loss is roughly twice the pleasure of an equivalent gain; cornerstone of prospect theory.

• Hyperbolic discounting — people discount the near future more steeply than the far future, leading to time-inconsistent preferences and present bias; explains procrastination and undersaving.

• Nudge — Thaler and Sunstein: a choice architecture intervention that steers behavior toward better outcomes without coercion or financial incentives (e.g., default enrollment in pension plans). The concept is developed by Richard Thaler and Cass Sunstein in Nudge: Improving Decisions about Health, Wealth, and Happiness, where it is tied to choice architecture and libertarian paternalism. The book argues that small policy design changes can steer decisions about health, wealth, and happiness without coercion, often by using opt-out defaults.

• Behavioral economics — Thaler, Kahneman, Tversky; systematic cognitive biases (loss aversion, anchoring, hyperbolic discounting) cause deviations from rational choice. Nudge theory (Thaler/Sunstein). It studies how psychology shapes economic decision-making instead of assuming perfectly rational agents, and is associated with ideas such as bounded rationality, heuristics, framing, and libertarian paternalism.

  • behavior — Behavior here means the choices and actions studied by economics and psychology, especially in decision theory and behavioral economics. Clues include Simon’s satisficing, Kahneman and Tversky-style heuristics, and Thaler’s nudges and critiques of homo economicus.

  • choice architecture
    • Nudge: Improving Decisions about Health, Wealth, and Happiness — Nudge: Improving Decisions About Health, Wealth, and Happiness is Richard Thaler and Cass Sunstein’s book on libertarian paternalism. It argues that choice architecture can steer people toward better defaults without eliminating freedom of choice.

  • choices — Choices are the options presented to decision-makers, and choice architecture is the arrangement of those options to influence behavior. Cass Sunstein and Richard Thaler’s Nudge popularized the idea that better framing can guide decisions without coercion.

  • Dan Ariely — Dan Ariely is a Duke economist known for behavioral work in books such as Predictably Irrational and The Honest Truth About Dishonesty. He is also the founder of the Center for Advanced Hindsight and a prominent critic of dishonest behavior.

  • Homo economicus — Homo economicus is the idealized perfectly rational agent of neoclassical economics. It has been criticized by behavioral and feminist economists and by cross-cultural experiments that failed to find it in practice.

  • libertarian paternalism — Libertarian paternalism is the policy idea associated with Richard Thaler and Cass Sunstein in Nudge and in their paper “Libertarian Paternalism Is Not an Oxymoron.” It aims to preserve free choice while using nudges, such as opt-out defaults, to steer decisions.

  • time discounting
    • discounting — Discounting is the tendency to value a reward less when it is delayed, a key idea in behavioral economics and decision theory. Its hyperbolic form is often used to explain procrastination and addiction, while exponential discounting uses a constant factor across time periods.
  • ultimatum game — The ultimatum game is a two-player bargaining game in which one player proposes how to split a sum of money and the other accepts or rejects the offer. If the offer is rejected, both players get nothing, even though a purely rational chooser would accept any positive amount. It is a standard experiment in behavioral economics because real players often reject unfair offers, and it is contrasted with the dictator game, where the second player has no veto power. Researchers use it to study fairness, culture, and decision-making.
• Consumer behavior
  • wealth effect — The wealth effect is the idea that a rise in wealth or income can increase consumer spending and confidence. In labor economics, it can also reduce hours worked when people feel richer.
• risk preference
  • risk averse — Risk averse describes someone who prefers avoiding losses over taking a fair gamble, even when the expected return is the same. In economics, the term is used for investors or decision-makers who choose the safer option when faced with uncertainty.
• Cass Sunstein — Harvard Law professor and legal scholar known for work on behavioral economics, especially coauthoring Nudge with Richard Thaler. He is associated with the ideas of libertarian paternalism and choice architecture, wrote Infotopia on collaborative knowledge production, served as the Obama administration’s regulatory czar, and argued for an anticaste principle in discussions of structural racism.

Market Failures and Public Finance

Explain market failures before comparing public responses.

Externalities and Market Failures

• Externalities, Shared Resources, and Public Goods

  • Externality — a cost or benefit falling on parties not involved in a transaction; negative (pollution) leads to overproduction; positive (vaccination) to underproduction relative to the social optimum. Common examples include pollution and environmental damage as negative externalities, and education, vaccination/herd immunity, parks, and other public goods as positive ones. Related concepts include Pigouvian taxes, Coase’s theorem, and network externalities from phones or fax machines.

  • Negative externality — cost imposed on third parties (e.g., pollution); market overproduces; corrected by a Pigouvian tax (Pigou, 1920). Economists treat it as a case where private incentives ignore social costs; it can arise from either a producer or a consumer, with pollution harming nearby residents or workers as a common example.

  • Positive externality — benefit to third parties (e.g., vaccination, education); market underproduces; corrected by subsidies.

  • Coase theorem — if property rights are well-defined and transaction costs are negligible, private bargaining leads to the efficient outcome regardless of initial assignment (Coase, 1960). Stigler later named the idea, which Coase developed in “The Problem of Social Cost” as an answer to externalities and Pigouvian taxation.

  • Public goods — non-excludable and non-rival; susceptible to the free-rider problem; government typically provides them. Examples: national defense, lighthouses. Public goods are nonrival and nonexcludable goods such as lighthouses and national defense that are vulnerable to the free-rider problem. They are central to Samuelson’s condition for efficient provision and to mechanisms like Groves-Ledyard and Lindahl taxation. These goods are usually provided by the government because private markets tend to underprovide them.

    • Congestible goods — Congestible goods are goods that are neither strictly public nor strictly private. They are characterized by moderate rivalry in consumption, with roads and subways serving as common examples.

    • free rider — A free rider is someone who benefits from a public good or cooperative arrangement without paying the cost of participation. Free riding is the behavior of benefiting from a public good without contributing to its cost. The term is often used in economics and political science to describe incentives that can undermine collective action, and it is closely associated with the tragedy of the commons.

    • free rider problem — Economic and public-choice problem in which people benefit from a public good without paying their fair share, leading to underprovision. Because nonpayers cannot easily be excluded, it creates a strong incentive to underprovide goods and services with shared benefits. It appears in discussions of collective action, climate mitigation, and local-government competition.

  • Common-pool resources — rival but non-excludable; susceptible to tragedy of the commons (overuse, Hardin 1968). Elinor Ostrom showed communities can self-govern commons (Nobel 2009). Common-pool resources are rival but non-excludable resources, making them susceptible to overuse and the tragedy of the commons (Hardin, 1968). Elinor Ostrom showed that communities can self-govern such resources, work recognized with the 2009 Nobel Prize in Economics.

  • Tragedy of the commons — Garrett Hardin (1968 Science article): unregulated shared resources are overexploited because each individual gains all the benefit of use but shares the cost with everyone; countered by Elinor Ostrom’s empirical work on successful community governance.

  • environmental economics

    • social cost of carbon — The social cost of carbon estimates the economic damage caused by emitting one additional ton of carbon dioxide. It is estimated with integrated assessment models such as Nordhaus’s DICE and RICE.

    • cap and trade — Cap and trade is a pollution-control policy that sets a cap on emissions and lets firms buy and sell permits. It is often discussed as a market-based response to climate change and other externalities, including acid rain regulation.

    • E. F. Schumacher — E. F. Schumacher was a German-British or British-German economist and environmental thinker who ran the British Coal Board. He is best known for Small Is Beautiful, which defended appropriate technology and decentralized, local-scale economics and influenced environmentalist thought.

    • The Limits to Growth — This 1972 Club of Rome report by Donella and Denis Meadows, Jorgen Randers, and William Behrens used computer modeling to study the limits of world resources. It became famous for projecting possible global collapse from unchecked growth in population, industry, and resource consumption.

  • Pigouvian taxes
    • Congestion pricing — Congestion pricing is a Pigouvian-style charge on driving in crowded urban areas. It has been used in cities like London, Stockholm, and Singapore to reduce traffic and pollution.
  • Property rights
    • private property — Private property is the institution of exclusive ownership that philosophers from Locke to Hegel defended in different ways. It is the target of Proudhon’s famous claim that “property is theft,” and it is central to debates over labor, ownership, and civil society.
  • Environmental taxes
    • Carbon tax — A carbon tax is a policy that prices greenhouse-gas emissions, and it is often discussed alongside cap-and-trade and other forms of carbon pricing. Australia briefly adopted such a tax before the Abbott government repealed it.
  • externalities

    • Coase’s Theorem — Coase’s theorem says that if property rights are clear and transaction costs are negligible, bargaining over externalities can reach an efficient outcome regardless of the initial allocation. It is associated with The Problem of Social Cost and often appears in discussions of pollution, Pigouvian taxes, and the limits of market bargaining.

    • Network externality — A network externality, or network effect, is an economic effect in which the value of a product rises as more people adopt it. It is especially important in communications, transportation, and standards-based markets.

    • Pigouvian tax — A levy designed to correct a negative externality by making harmful activities bear their social cost, often by charging producers the marginal damage they impose. It is named for economist Arthur Pigou and is commonly discussed as a policy response to pollution and other market failures; related debates contrast this approach with Ronald Coase’s analysis of externalities.

  • Government intervention
    • subsidy — A subsidy is financial aid given by a government or another body to support an activity, industry, or product. In political economy, the word often refers to state money used to bolster businesses or lower costs.
  • market failures
    • negative externalities — Negative externalities are costs imposed on third parties by economic activity, as in pollution or other spillover harms. Pigovian taxes are designed to correct them by making private costs closer to social costs.
  • Deadweight loss — welfare lost due to market inefficiency (monopoly pricing, taxes, externalities); the area of the triangle between supply and demand curves between competitive and distorted quantities. It can arise from taxes, monopoly pricing, price controls, and other distortions, and is often illustrated as the triangle between supply and demand showing lost surplus rather than revenue transferred to the government.
    • Deadweight welfare loss — Deadweight welfare loss is the reduction in total surplus caused by producing below the efficient level of output. In monopolistic competition, it appears as the gap between demand and marginal cost over the relevant quantity range.

  • Rent-seeking — using resources to obtain transfers (e.g., lobbying for monopoly privileges) rather than creating wealth. Lobbying, regulatory capture, and the pursuit of monopoly rents are classic examples, and Tullock’s paradox asks why such behavior is often so cheap relative to the gains it can produce.

  • transaction costs — Transaction costs are the costs of using the market, including bargaining, search, and information expenses. Coase’s theory of the firm and Coase’s theorem both use them to explain why firms exist and why efficient bargaining can occur when those costs are absent.
    • Ronald H. Coase — Ronald H. Coase was an economist whose work focused on transaction costs, property rights, and the organization of firms. He is best known for the Coase theorem and for articles such as The Nature of the Firm and The Problem of Social Cost.
• Economic analysis of law
  • Law and economics — Law and economics is the school that applies economic reasoning to legal rules, especially through efficiency, wealth maximization, and incentive analysis. Richard Posner is one of its best-known figures, and the field is closely associated with his Economic Analysis of Law and other Chicago School writing.

    • Frank Easterbrook — Frank Easterbrook is a judge on the Seventh Circuit and a major figure in law and economics. He coauthored The Economic Structure of Corporate Law with Daniel Fischel and is often paired with Richard Posner as part of that movement.

    • The Problem of Social Cost — “The Problem of Social Cost” is Ronald Coase’s classic 1960 essay on externalities, property rights, and transaction costs. It gives rise to the Coase theorem, arguing that efficient outcomes depend less on the initial allocation of legal rights than on bargaining when transaction costs are low.

• Economic goods
  • public good — A public good is nonrival and nonexcludable, so one person’s consumption does not reduce another’s and no one can easily be kept from using it. Because of the free rider problem, private markets tend to underprovide it, so these goods are often supplied by governments. Common examples include law enforcement, streetlights, tornado sirens, national defense, lighthouses, information, and fireworks.
• public economics
  • public — Public refers to the government-owned or non-private side of the economy, including public goods, public finance, and the public sector. The term also appears in public choice theory and in discussions of public administration and the public sphere. It is used for goods that are non-excludable and non-rivalrous, such as clean air.
• public finance
  • national debt — National debt is the total money owed by a government, often measured relative to GDP and discussed through debt ceilings and fiscal crises. Clues may reference the Euro convergence criteria, Ricardian equivalence, and sovereign debt restructuring.
    • National Debt Clock — The National Debt Clock is the Times Square electronic display created by Seymour Durst in 1989 to track the U.S. government debt. It became famous for racing upward too quickly for its computer to calculate and was dismantled in 2000 after serving as a fiscal warning sign.
  • Tax credits
    • Earned Income Tax Credit — The Earned Income Tax Credit is a U.S. tax benefit for low-wage workers that can produce a refund larger than their withholding. It is often praised for encouraging work rather than replacing wages with lump-sum welfare payments.
  • Taxation — Taxation is the government’s raising of revenue through taxes such as excises, tariffs, income taxes, poll taxes, and sales taxes. Economic discussions of taxation often mention Henry George, David Ricardo, and Pigovian taxes.

    • capital gains — Capital gains are the profits realized when an asset is sold for more than its purchase price, including assets such as stocks, bonds, and property. They are commonly discussed in tax policy and are often taxed at preferential rates, especially in contexts involving short-term versus long-term gains and in cases involving stocks or real estate.

    • deductions — Deductions are amounts subtracted from gross income to determine taxable income. Taxpayers may take the standard deduction or itemize eligible expenses such as charitable contributions and certain business-related items.

    • estate tax — An estate tax is a levy on property transferred at death, often called a death tax by its critics. It is imposed on large inheritances and is often discussed alongside state and federal inheritance rules.

    • flat tax — A flat tax is a tax system in which everyone pays the same percentage rate regardless of income. It is often discussed alongside the Laffer curve in debates over tax policy.

    • Hauser’s Law — Hauser’s Law is the claim that postwar U.S. federal tax revenues have hovered at about 19.5 percent of GDP despite changes in tax rates. It is named for economist Kurt Hauser.

    • Luxury Tax — A luxury tax is an excise tax on nonessential goods or services. It is often discussed as a levy on expensive purchases such as premium real estate or other high-end consumer items.

    • progressive tax — A progressive tax is one in which the tax rate rises as income rises. This makes higher-income taxpayers pay a larger share of their income than lower-income taxpayers.

    • regressive — A regressive tax takes a larger share of income from poorer taxpayers than from richer ones. Sales taxes and payroll taxes are common examples because of their disproportionate effect on lower-income people.

    • regressive taxes
      • regressive tax — A regressive tax is one whose burden falls more heavily on lower-income people because the effective rate takes a larger share of their income. Sales taxes are a standard example, since the same rate consumes a greater fraction of a poor person’s resources than a rich person’s.
    • tax — A tax is a compulsory payment to a government, and economists distinguish forms such as income, sales, progressive, and regressive taxes. Tax policy is often analyzed with ideas like deadweight loss, the Laffer curve, Pigouvian taxation, and historical levies such as jizya and Danegeld.
      • excise tax — An excise tax is a levy on a specific good or activity, often one considered harmful such as alcohol or tobacco. Britain relied on excise taxes to strengthen its fiscal-military state, and the Whiskey Rebellion in the United States protested one such tax.

    • tax farming — Tax farming was a system in which a ruler auctioned off the right to collect taxes to private agents who paid a fixed sum in advance. It is associated with the French Ferme générale and with Ottoman financial arrangements such as iltizām and malikâne.

    • tax rate — A tax rate is the percentage or fraction of income or a transaction owed to the government, whether described in marginal, effective, or statutory form. It appears in the Laffer curve, progressive brackets, and deadweight-loss analyses of taxation.

    • Taxes — Taxes are payments levied by governments on income, sales, property, and other bases, and are central to fiscal policy and public finance. Common forms include income, ad valorem, proportional, progressive, and regressive taxes. In economics, Pigouvian taxes are used to internalize negative externalities. Related clues may involve the Sixteenth Amendment, the Laffer curve, withholding, tariffs, and economists such as Pigou, Tobin, Lindahl, and Ramsey, as well as colonial protest against taxation without representation.

      • ad valorem tax — An ad valorem tax is a tax assessed as a percentage of value rather than a fixed amount. Sales taxes, property taxes, and value-added taxes are common examples.

      • capital gains tax — Capital gains tax is the tax on profit from selling an asset such as stocks, bonds, or other investments. It is often contrasted between short-term and long-term rates, with the long-term rate used to encourage investment over speculation.

      • Income tax — A levy on earnings that became a major federal revenue source in the United States after the Sixteenth Amendment, which made it a permanent federal power. It had earlier been adopted during the Civil War era and later reinstated after being ruled unconstitutional. Related ideas include marginal tax rates, negative income tax, and the distinction between federal and state taxation.

        • alternative minimum tax — The alternative minimum tax is a parallel U.S. income tax designed to make sure high earners cannot eliminate their liability through deductions. Taxpayers owe it only when the tentative AMT exceeds their regular income tax.

        • progressive income tax — A progressive income tax charges higher percentages of income to higher earners through graduated brackets. It is the opposite of a flat tax.

    • ad valorem — Ad valorem is the Latin phrase meaning “according to the value.” It describes taxes or duties calculated as a percentage of the value of goods or property rather than as a flat amount.
• Fraud schemes
  • pyramid scheme — A pyramid scheme is a fraud that depends on recruiting new investors or members, with money from later participants used to sustain earlier ones. It differs from ordinary multi-level marketing because the sale of goods is not the main source of revenue, and it collapses once new recruits stop coming in.
• insurance — Insurance is the financial service that protects against risk in exchange for premiums. It is a standard economics clue through adverse selection and moral hazard, and it also appears in architecture questions through company-named buildings.
  • cost sharing
    • deductible — A deductible is the amount an insured person must pay out of pocket before an insurance plan begins paying benefits. It is a standard form of cost sharing and may be described in flat or percentage terms.
  • health insurance — Health insurance is the service sold during open enrollment on marketplaces created under the Affordable Care Act. It is also the industry associated with companies like Aetna and Blue Cross Blue Shield, and with laws and acronyms such as HIPAA, COBRA, and ACA. The clues point to the general insurance product rather than a specific company or government program.

    • Blue Cross — Blue Cross is a major American hospital-insurance program that began as a prepaid hospital care plan. It became closely associated with Blue Shield and was adopted and organized nationally through the American Hospital Association.

    • health insurance claims — Health insurance claims are the bills submitted to insurers for reimbursement after medical care. They are often encoded electronically in the 837 format and reviewed by clearinghouses or scrubbers for errors, missing authorizations, and improper coding.

    • Blue Shield — Blue Shield began in Tacoma, Washington, as an employer-backed medical care plan for workers in the Pacific Northwest. It later became one of the associated plans that merged with Blue Cross to form the Blue Cross Blue Shield system.

    • managed care
      • Preferred Provider Organization — A preferred provider organization is a type of health insurance arrangement and managed care plan that contracts with independent doctors and hospitals to offer reduced rates. It combines fee-for-service and HMO-style networks: patients can see non-affiliated providers, but they usually pay more out of pocket than they would inside the network.
    • Medicare — Medicare is the U.S. federal health insurance program for people age 65 and older and for some people with disabilities. It includes Part C, or Medicare Advantage, and often appears in single-payer proposals such as ‘Medicare for All.’ Clues also mention drug-price negotiation, catastrophic coverage changes, and anti-fraud efforts.
  • Whole life insurance — Whole life insurance is a policy with fixed premiums and a guaranteed death benefit for the policyholder’s entire life. It also builds cash value that can be borrowed against or redeemed.
• Economics of child care
  • daycares — Daycares are childcare centers whose behavior can be studied as markets and social norms interact. The prompts point to classic examples about fines for late pickup and debates over whether monetary incentives reduce altruistic behavior.

Public Finance and Taxation

• Laffer curve — at tax rates of 0% and 100%, revenue is zero; somewhere in between is the revenue-maximizing rate. Theoretical basis for supply-side tax-cut arguments. It is associated with Arthur Laffer, the napkin sketch story, and tax-cut politics under Reagan and the Kemp-Roth Act.
  • Arthur Laffer — Arthur Laffer is the economist associated with the Laffer curve, which argues that very high tax rates can reduce revenue. His work is tied to supply-side economics and the famous restaurant-napkin sketch.
• Thomas Paine
  • Agrarian Justice — Agrarian Justice is Thomas Paine’s 1797 pamphlet proposing taxes on landownership and inheritance to fund payments for the poor and elderly. It is often cited as an early precursor to basic income ideas.
• consumption taxes
  • sales tax — A sales tax is an indirect consumption tax collected on the purchase of goods or services. It is often contrasted with value-added tax systems and is commonly regressive because it applies at a flat rate.

• cost-benefit analysis — Cost-benefit analysis is a quantitative method for weighing the social advantages of a policy or project against its costs. It was developed by Arsène Dupuit and later became important in evaluating public works such as flood control.

• Housing Act
  • Section 8 — Section 8 is the Housing Act program that subsidizes rent for low-income tenants. The name also refers to Article I, Section 8 of the U.S. Constitution, which grants Congress powers including the patent system.
• lotteries — A lottery is a drawing or game of chance in which a random selection decides the outcome. In literature, it appears in works such as Shirley Jackson’s “The Lottery” and as the source of Babette’s fortune in “Babette’s Feast.”

  • The National Lottery — The National Lottery is the British lottery event whose weekly draws include games such as Lotto and Thunderball. It has been broadcast with a distinctive on-air role for the “voice of the balls,” and its televised draws have occasionally drawn protests.

  • the state lottery — The state lottery is a government-run lottery, a form of gambling often debated for its social effects and public revenue. One historical controversy around it involved Louisiana, where opponents denounced the lottery as the ‘golden octopus.’

• lottery
  • winning the lottery — Winning the lottery is the central event in stories such as “The Lottery” and “Babette’s Feast,” where sudden wealth or chance selection changes a character’s fate. The clue set also links it to Borges’s “The Lottery in Babylon” and to questions about windfalls and post-lottery life.
• lottery winners
  • Frank and Shirley Capaci — Frank and Shirley Capaci were the couple who won a large Powerball jackpot and chose a lump-sum payout. The clues identify them as the 1998 winners of a $194 million prize.
• pensions — Pensions are retirement payments or funds set aside for old age, including public systems such as Social Security and state-run retirement schemes. The clues also point to political disputes over pension reform and retirement-age changes.
  • Dr. Francis Townsend — Dr. Francis Townsend was a Depression-era physician who proposed old-age pensions to stimulate spending. His Townsend Plan promised monthly payments for the elderly and influenced later Social Security debates.
• Poverty measurement
  • Poverty Line — This U.S. statistic marks the income threshold below which a household is considered poor, often computed from basic food budgets. It was formalized in the 1960s after attention to Michael Harrington’s The Other America and later rose for a family of four.
• retirement accounts

  • Individual Retirement Account — An Individual Retirement Account is a tax-advantaged savings account for retirement. Traditional and Roth accounts are the main types, and early withdrawals are penalized under the usual rules described in the clue.

  • Roth IRA — A Roth IRA is a retirement account funded with after-tax dollars that can grow and be withdrawn tax-free if the eligibility rules are met. It was created by the Taxpayer Relief Act of 1997 and named for Senator William Roth.

• Retirement plans

  • 401(k) plans — 401(k) plans are employer-based retirement accounts named for the section of the tax code that authorizes them. They allow workers to defer salary into tax-advantaged savings, often with employer matching contributions.

  • Defined-contribution plans

    • 401(k) plan — A U.S. employer-sponsored defined-contribution retirement plan named for section 401(k) of the tax code. It lets workers defer part of their pay on a tax-advantaged basis, and employers may make deductible contributions or matching deposits; taxes are generally deferred until withdrawal. It is used as a substitute for the older pension model.
• tax compliance
  • paying your taxes — The action is paying your taxes, especially the income taxes due around April 15 in the United States. The clues reference songs and cartoons that satirize tax payment, from popular music to wartime propaganda.
• Tax incidence
  • Arnold Harberger — Arnold Harberger was an economist known for work on tax incidence and for the Harberger triangle, a diagram used to estimate deadweight loss from market distortions. His name often appears in questions about excess burden and the cost of taxation.
• treasuries
  • Exchequer — An exchequer is a national treasury, especially the British treasury. In Britain, the Exchequer was originally the room where royal treasure was stored and later came to mean the department that receives and spends revenue.
• Treasury secretaries
  • Robert Rubin — Robert Rubin was the Clinton Treasury Secretary who remained influential in economic policy after leaving office. He later became a senior figure at Citigroup, where he was hired as a chairman after the company’s merger.
• United States economic policy
  • Council of Economic Advisers — The Council of Economic Advisers is the three-member White House body that summarizes its recommendations in the Economic Report of the President. Created by the Employment Act of 1946, it has included figures such as Alan Greenspan and several later chairs.
• United States fiscal policy
  • Raising the debt ceiling — Raising the debt ceiling is the legislative action that increases the amount the federal government may legally borrow. It became a major political fight in 2011, when the Budget Control Act and the prospect of a default dominated debate.
• United States Secretary of the Treasury
  • Henry Paulson — Henry Paulson was a former CEO of Goldman Sachs before becoming U.S. Secretary of the Treasury. He is often associated with the 2008 financial crisis and the push to stabilize Fannie Mae and Freddie Mac.
• War economy
  • War Industries Board — Led by Bernard Baruch during World War I, the War Industries Board coordinated industrial production for wartime needs. Its efforts to manage the wartime economy later drew scrutiny from the Nye Committee.
• Land value taxation
  • Georgism — Georgism is the economic philosophy associated with Henry George and the single-tax movement. It inspired communities such as Arden and Fairhope, and it influenced Elizabeth Magie’s game that became Monopoly.
• Sales taxes
  • Value-added tax — A tax on goods and services collected at each stage of production and distribution rather than only at the final sale. It is a major source of revenue in many European countries, is often contrasted with a standard sales tax, and Japan’s introduction of it contributed to the fall of Prime Minister Noboru Takeshita’s government in 1989.

Macroeconomics, Money, and Growth

Connect aggregate output, prices, money, employment, and growth.

Macroeconomics

• macroeconomics — Macroeconomics studies economy-wide phenomena such as inflation, unemployment, growth, and the effects of fiscal and monetary policy. It is the branch of economics contrasted with microeconomics, and its models include Keynesian IS-LM analysis and DSGE frameworks.

  • aggregate demand — Aggregate demand is the total demand for goods and services in an economy, usually written as consumption plus investment plus government spending plus net exports. In the AD-AS model, it slopes downward with respect to the price level and is a standard focus of Keynesian macroeconomics.

  • aggregate demand curve — The aggregate demand curve is the downward-sloping macroeconomic curve showing total planned spending at different price levels. Its shape is explained by the real balances effect, the interest-rate effect, and the international substitution effect.

  • aggregate supply — Aggregate supply is the total quantity of goods and services firms are willing to produce at a given price level. In macroeconomics it is graphed against aggregate demand, and the long-run aggregate supply curve is vertical. Its upward-sloping short-run form shifts right when input costs fall, lowering the market-clearing price. The term is often contrasted with demand and is distinguished from simple supply by the economy-wide price level.

  • Aggregate supply and aggregate demand — Aggregate supply and aggregate demand are the two main Keynesian macroeconomic curves used to relate output and the price level. Aggregate demand slopes downward, while aggregate supply slopes upward and is used in discussions of fiscal policy and the multiplier.

  • aggregate supply curve — The aggregate supply curve relates the price level to the total output firms are willing to produce. Models by Friedman, Lucas, and others are used to explain shifts or slopes in this macroeconomic relationship.

  • aggregate variables
    • aggregate — Aggregate is the economic adjective used for totals such as aggregate demand and aggregate supply. It also appears in discussions of aggregation bias, representative-agent modeling, and macroeconomic total expenditure.
  • business cycle theory
    • real business cycle theory — Real business cycle theory explains recessions as efficient responses to real shocks, especially technology or productivity shocks, rather than to nominal disturbances. The theory is associated with Kydland and Prescott and with the use of calibration and detrending methods such as the HP filter.
  • Capital depreciation
    • depreciation — Depreciation is the loss of value of tangible assets over time, and in economics it can also mean a currency losing value relative to others. It is often contrasted with amortization for intangible assets.

  • consumption function — The consumption function relates total consumer spending to disposable income, often written with consumption as C. In Keynesian models its slope is the marginal propensity to consume, and Friedman’s permanent income hypothesis was an important attempt to explain its shape. It is also central to work on poverty and welfare in modern economics.

  • Gross domestic product — Gross domestic product is the total market value of final goods and services produced within a country, territory, or economy in a given period. It is commonly calculated by the expenditure approach as consumption plus investment plus government spending plus net exports (C + I + G + (X - M)). It is used to measure economic output and growth, including growth rates and per-capita comparisons. Real versus nominal GDP is compared using the GDP deflator. It differs from gross national product because ownership is not the deciding factor.
    • real GDP — Real GDP is the value of output measured using prices from a fixed base year rather than current prices. Because it holds prices constant, it is used to compare economic growth while removing the effect of inflation.

  • investment — Investment is the economic decision to spend money now in hopes of greater future return, whether by buying assets or adding productive capital. In macroeconomics it appears in the GDP identity and is often linked to savings, growth, and capital formation.

  • LM curve — The LM curve is the money-market curve in the IS-LM model, showing equilibrium between liquidity preference and the money supply. It is tied to income and interest rates, so monetary policy shifts it and a very flat or steep version has different implications for fiscal policy.

  • long run — The long run is the economic time horizon in which Keynes said that “we are all dead.” It is also the frame used for models of accumulation and for value-investing arguments that markets eventually behave like weighing machines rather than voting machines.

  • menu costs — Menu costs are the expenses firms incur when changing posted prices, especially in discussions of inflation and price stickiness. New Keynesian economics treats these costs as a microfoundation for short-run non-neutrality of money.

  • Monetary economics

    • Fisher equation — The Fisher equation relates nominal interest, real interest, and inflation. It is a standard economics identity used to approximate how expected inflation changes the nominal rate.

    • Modern Monetary Theory — Modern Monetary Theory is a heterodox macroeconomic view that argues sovereign governments can finance spending by issuing currency and are constrained mainly by inflation rather than revenue. It is associated with Stephanie Kelton and William Mitchell, and often appears in debates over taxes, deficits, and full-employment policy.

  • multiplier — The multiplier is the macroeconomic factor that measures how a change in investment or government spending produces a larger change in equilibrium output. It appears in Keynesian models, the fiscal multiplier, and the multiplier-accelerator business-cycle framework.

  • National income — National income is the total income earned by a country’s residents and firms, often summarized as the sum of wages, interest, rent, and profit. It is closely related to GDP and GNP and is used as a broad measure of economic output and welfare.

  • Output gap — The output gap is the difference between actual GDP and potential GDP. It is often discussed in macroeconomics because it helps describe slack in an economy and can be related to inflation stabilization.

  • rational expectations theory — Rational expectations theory holds that economic agents form expectations consistent with the model’s predictions on average. It is associated with John Muth and later with Robert Lucas, and it underlies ideas such as the efficient markets hypothesis.

  • Robert Barro — Robert Barro is an economist associated with the Ricardian equivalence idea and with work on economic growth and rare disasters. His name is tied to the Barro variables and to textbooks and papers on macroeconomics, growth, and fiscal policy.

  • Saving — Saving is the economic activity of setting aside income instead of spending it; in macroeconomics, it is the portion of income not consumed and equals investment in the standard closed-economy accounting identity. It is central to the Solow model, the Ramsey-Cass-Koopmans model, discussions of thrift and deferred consumption, the paradox of thrift, savings gluts, and commitment devices such as ROSCAs and 401(k) plans.

  • supply shocks
    • supply shock — A supply shock is a sudden disruption of aggregate supply caused by a change in a supply determinant. It can raise prices and contribute to stagflation, as with droughts, cartels, or new regulation.

National Accounts

• GDP (Gross Domestic Product) — the market value of all final goods and services produced within a country in a period. Expenditure approach: GDP = C + I + G + (X - M).

• Nominal vs real GDP — nominal uses current prices; real adjusts for inflation using a base-year price level. GDP deflator = (nominal/real) × 100.

• GNP / GNI — Gross National Product / Income counts production by residents regardless of location; differs from GDP by net factor income from abroad.

• GDP per capita — common (imperfect) measure of living standards; does not capture inequality or non-market activity.

• National income accounting

  • Gross National Product — Gross national product is the market value of the final goods and services produced by a nation’s residents or citizens, regardless of where production occurs. It includes income earned abroad and is often contrasted with GDP, which counts output within a country’s borders instead. Some descriptions also note that it differs from national income by including depreciation and indirect business taxes.

  • Nominal GDP — Nominal GDP is gross domestic product measured at current prices without adjusting for inflation. It values output using the prices that existed in the year the goods and services were produced.

• nominal and real
  • nominal — Nominal values are measured in current dollars and have not been adjusted for inflation. Economists contrast nominal GDP with real GDP to remove the effect of price changes over time.

Inflation and Unemployment

• Prices, Inflation, and Purchasing Power
  • Inflation — sustained rise in the general price level. Measured by the CPI (consumer price index) or PCE (personal consumption expenditures, the Fed’s preferred measure). Economists link it to monetary expansion, demand-pull and cost-push pressures, and tradeoffs with unemployment such as the Phillips curve.

    • cost-push inflation — Cost-push inflation is inflation caused by rising input costs such as wages and raw materials. It occurs when prices rise because firms must cover higher expenses and preserve profits, and it is distinguished from demand-pull inflation because prices rise from reduced aggregate supply rather than excess demand or spending.

    • demand-pull inflation — Demand-pull inflation occurs when aggregate demand rises faster than the economy’s ability to produce goods and services. It is driven by too much spending chasing too few goods, and can often be restrained by contractionary fiscal policy.

    • Disinflation — Disinflation is a slowdown in inflation: prices are still rising, but the rate of increase is lower than before. It is the opposite of deflation and is often treated as a goal of central banks.

    • inflation rate — The inflation rate measures how fast prices rise and money loses purchasing power, usually tracked with the CPI. It is linked to the Phillips curve and to ideas like the unemployment tradeoff, the Taylor rule, and 1970s stagflation.

    • price index — A price index measures changes in the cost of a fixed basket of goods over time, making it a standard tool for tracking inflation. Common examples include consumer price indices and related government measures.

    • Whip Inflation Now — Whip Inflation Now was Gerald Ford’s anti-inflation campaign slogan during the economic turmoil of the 1970s. It is associated with campaign buttons, public appeals against stagflation, and Ford’s broader response to the post-Nixon presidency.

  • CPI vs GDP deflator — CPI uses a fixed basket (Laspeyres); GDP deflator covers all domestically produced goods with a changing basket.

  • Types of inflation — demand-pull: excess aggregate demand; cost-push: supply-side cost increases; built-in (wage-price spiral).

  • Hyperinflation — extremely rapid inflation; classic cases: Germany 1921–23, Zimbabwe 2007–09. In Weimar Germany in 1923, reparations, money printing, and the Ruhr crisis helped make the mark nearly worthless.

  • Deflation — falling price levels; dangerous when it induces delayed spending and debt deflation spirals. It is the opposite of inflation and can make debt burdens harder to repay. Irving Fisher’s debt-deflation theory links deflation to liquidation, distress selling, and a downward spiral in asset prices. It is a standard topic in monetary policy and macroeconomics.

  • Price indices

    • Consumer Price Index — The Consumer Price Index is a standard measure of changes in the cost of a market basket of goods and services. It is used as an inflation indicator and for cost-of-living adjustments, poverty thresholds, and similar comparisons. The index is computed by the Bureau of Labor Statistics in several variants and is based on a fixed-basket Laspeyres approach; its categories include food, shelter, clothing, transportation, and medical expenses, and it is often discussed in connection with substitution bias.

    • GDP deflator — The GDP deflator is a measure of the overall price level defined by comparing nominal GDP to real GDP. It is commonly used as an inflation index, much like the consumer price index. Equivalently, it is nominal GDP divided by real GDP, multiplied by 100. This makes it a standard way to infer changes in the economy’s general price level.

    • Gross Domestic Product implicit price deflator — The GDP implicit price deflator is a current-weight price index based on the ratio of nominal domestic production to the same output valued at base-period prices. It is used to measure changes in the price level of all domestically produced final goods and services.

    • Paasche index — The Paasche index compares current prices or quantities against a base period using current-year weights. Because it uses present buying patterns, it tends to understate price increases.

    • Paasche price index — The Paasche price index weights each item by current-period consumption rather than by a fixed base-year bundle. That makes it prone to understating price increases relative to the Laspeyres index.

    • price indices or price indexes — Price indices or price indexes measure changes in the overall cost of a basket of goods and services over time. The consumer price index is the most familiar example, and variants like Laspeyres, Paasche, and Case-Shiller appear in economics questions.

      • Laspeyres index — A price index named for the French economist Étienne Laspeyres. It measures changes using base-period quantities as weights, valuing the current period with an earlier market basket. Because it fixes the basket from the base period and assumes consumers do not substitute away from relatively more expensive goods, it is often said to overstate inflation or price increases relative to the Paasche index, which uses current-period weighting.

  • shoeleather costs — These are the wasted resources created by inflation when people try to reduce cash holdings, such as the inconvenience and time spent making more frequent trips to the bank.

  • nominal rigidity — The tendency of prices or wages to adjust slowly, making them relatively inflexible in the short run; it is used in economics to explain unemployment and the kinked demand curve. In New Keynesian models it is often modeled with menu costs, Calvo pricing, and staggered contracts.
• Employment, Wages, and Inflation Tradeoffs
  • Unemployment — being without employment while available for work and seeking it; the unemployment rate is unemployed ÷ labor force, not unemployed ÷ total population. In the U.S. Current Population Survey, active job search within the preceding four weeks normally determines eligibility, with an exception for workers awaiting recall from temporary layoff. The labor force is employed plus unemployed people.³ Economists distinguish frictional, structural, and cyclical unemployment, and the concept is often modeled with the Phillips curve and Beveridge curve. Theories by Friedman, Phelps, Shimer, and others address its relationship to inflation and output.
    • cyclical unemployment — Cyclical unemployment is unemployment caused by downturns in the business cycle or a decline in aggregate demand. It is often discussed as a recessionary form of unemployment, distinct from frictional unemployment.
      • Cyclical — Cyclical unemployment is caused by recessions and booms in the business cycle rather than by a worker’s skills or job search. It rises when the economy slows and falls when demand recovers.

    • Cyclical, structural, and frictional unemployment — Cyclical, structural, and frictional unemployment are the three basic types of unemployment. They are associated respectively with the business cycle, long-term industrial change, and ordinary job turnover in a dynamic economy.

    • frictional unemployment — Frictional unemployment is the temporary unemployment that occurs when workers are between jobs or moving from one job to another, including while searching for new jobs. It reflects normal labor-market turnover rather than a deeper structural mismatch and is often associated with labor-market search theory and the Beveridge curve.

    • Seasonal unemployment — Seasonal unemployment is unemployment caused by changes in labor demand at different times of year. It is the kind of unemployment that can affect lifeguards when their work is needed only during part of the year.

    • structural unemployment — Structural unemployment is unemployment caused by a mismatch between workers’ skills and the available jobs in the labor market. It reflects longer-term economic change rather than business-cycle fluctuations and is one of the forms of unemployment that can contribute to the natural rate of unemployment.

    • Underemployment — Underemployment is the condition in which workers are employed in jobs below their skill, training, or desired level. It is often discussed alongside labor hoarding and was especially visible during the 2008 financial crisis.

    • unemployed — Unemployed describes the status of people without work, including the kind of short-term joblessness economists call frictional unemployment. The clue about matching functions refers to search-and-matching models of labor market unemployment.

  • Discouraged workers — people who want work but have stopped searching because they believe suitable jobs are unavailable. Under U.S. survey definitions they are outside the labor force, so they are excluded from the headline unemployment rate. This makes a fall in unemployment different from proof that everyone who wants a job has found one.³

  • Unemployment types — frictional unemployment arises during job search and matching; structural unemployment reflects persistent mismatches between workers and available jobs; cyclical unemployment rises with weak aggregate demand. These explain different mechanisms, while NAIRU describes an estimated inflation-related reference rate.⁴⁵

  • Natural rate of unemployment — the reference unemployment rate associated with underlying labor-market conditions when cyclical forces have abated. It can change as matching, institutions, and workforce composition change. The term is often used alongside NAIRU, but the natural-rate hypothesis and an empirical rate consistent with non-accelerating inflation are not identical concepts.⁵

  • NAIRU — the non-accelerating inflation rate of unemployment, an estimated unemployment rate at which inflation has no tendency to rise or fall in the specified model. It is not zero unemployment or a directly observed fixed number. Inflation expectations and supply shocks matter, and shocks can make NAIRU differ from the natural rate.⁵
    • Non-Accelerating Inflation Rate of Unemployment — The Non-Accelerating Inflation Rate of Unemployment, or NAIRU, is the unemployment level consistent with stable inflation. Economists use it in discussions of the Phillips curve and the natural rate of unemployment.

  • Okun’s law — an empirical negative association between unemployment and output, often expressed using the unemployment gap and GDP relative to potential, or changes in unemployment and GDP growth. A roughly two-to-one output-gap rule is a common shorthand, but estimates vary by period, country, and specification. It is not a universal exact coefficient.⁶ It is associated with economist Arthur Okun.

  • Beveridge curve — the usually downward-sloping relationship between the job-vacancy rate and unemployment rate. Weak demand tends to bring fewer vacancies and more unemployment. Shifts in the curve can indicate changes in matching and recruitment, so movement along a curve and movement of the curve convey different information. This pairs unemployment with vacancies; the Phillips curve pairs it with wage or price inflation.⁷ It is used in labor economics to show how matching frictions and labor-market slack move the economy along or shift the curve. It is commonly discussed alongside other macroeconomic relationships such as Okun’s law and measures of frictional unemployment.

  • Shapiro–Stiglitz model / efficiency wages — a model in which employers cannot perfectly monitor effort and pay wages that make keeping a job valuable. The threat of dismissal discourages shirking because finding another job takes time; involuntary unemployment can persist in equilibrium. This is one explanation for efficiency wages and unemployment, not a claim that every unemployed person was dismissed for shirking.⁸

  • Phillips curve — Phillips’s 1958 paper studied unemployment and the rate of change of money wages in the United Kingdom. Later versions relate unemployment or economic slack to price inflation. Expectations and supply shocks affect the relationship; it is not a fixed policy menu valid across all periods.⁹ Named after A. W. H. Phillips, whose 1958 work underlies it. The relation was later popularized by Solow and Samuelson, and long-run critiques by Friedman and Phelps led to extensions such as the NAIRU.

  • inflation-unemployment
    • stagflation — Stagflation is the economic condition in which inflation stays high while unemployment also remains high. It is often discussed in connection with the Phillips curve and the economic troubles of the 1970s.
  • Labor statistics
    • labor force participation rate — The labor force participation rate is the share of the working-age population that is employed or actively seeking work. It differs from the unemployment rate because it measures attachment to the labor market, not just joblessness. Claudia Goldin used historical evidence to show that women’s labor force participation often follows a U-shaped pattern over time. The statistic is central to labor-market analysis and demographic comparisons.
  • search and matching theory — Search and matching theory studies how workers and firms, or other market participants, find each other and form matches when frictions are present. It is associated with the Diamond-Mortensen-Pissarides framework and with models of labor-market unemployment and equilibrium search.
    • Coordination failure
      • Diamond coconut model — The Diamond coconut model is a search-theoretic model that explains coordination failure in markets. It is named for Peter Diamond and the classic coconut economy setup. The model is used to show how expectations can create inefficient equilibria and multiple unemployment rates. It is a favorite New Keynesian illustration of labor-market search frictions.
  • Efficiency wage theory
    • Shapiro–Stiglitz model — The Shapiro–Stiglitz model explains efficiency wages by showing that firms may pay above-market wages to discourage shirking. Because wages stay above the market-clearing level, the model implies persistent unemployment.
• Economic indicators

  • Consumer confidence index — The consumer confidence index measures how optimistic the public is about the economy and future spending conditions. It is commonly built from surveys of current and expected business conditions, jobs, and income prospects.

  • misery index — The misery index is an economic indicator that combines inflation and unemployment as a rough measure of public unhappiness. It is often contrasted with broader well-being measures and has been adapted in different political and regional contexts.

• Government agencies
  • Bureau of Labor Statistics — The Bureau of Labor Statistics is a U.S. Department of Labor agency that compiles employment and wage data for the federal statistical system, including official employment numbers and the Consumer Price Index. Its monthly jobs reports and payroll-based labor statistics are widely tracked in finance and government, and it is also known for keeping pre-release data in a secured lock-up room.

Business Cycles and Policy

• Business Cycles and Aggregate Demand

  • Business cycle phases — expansion, peak, contraction (recession), trough. A recession is conventionally two consecutive quarters of negative real GDP growth.

  • Business cycles — Business cycles are recurring fluctuations in economic activity, moving through expansion and recession. They are tracked and dated by economists and institutions like the NBER, and associated with the Great Moderation, recession and depression, Kondratieff and Kuznets waves, and real business cycle theory from Kydland and Prescott.

    • business cycle — The business cycle is the recurring pattern of expansion, stagnation, contraction, and recession in economic activity over time. Economists such as Schumpeter and Hayek discussed its phases and causes, including credit conditions and long-term cycles; Hayek explained it as a consequence of distorted credit expansion and malinvestment.

    • Juglar Cycle — The Juglar cycle is a business cycle of roughly eight years associated with Clément Juglar. It describes recurring booms and busts in economic activity.

    • Kondratieff Long Wave Cycle — The Kondratieff long wave cycle is an economic theory proposing recurring roughly fifty-to-sixty-year capitalist cycles of expansion and stagnation. It is named for the Soviet economist Nikolai Kondratiev.

    • Kondratiev waves — Kondratiev waves are long economic cycles, usually said to last about half a century. They are named for Nikolai Kondratiev and were later linked by Schumpeter to waves of technological innovation.

    • Nikolai Kondratieff — Nikolai Kondratieff was the Soviet economist who proposed long-wave business cycles, arguing that capitalism moved through extended periods of expansion and stagnation. His work on trend cycles made him a major name in economic history before he was sent to Siberia.

    • recession — A recession is an economic downturn usually defined by two consecutive quarters of negative growth, and unemployment often rises during it. The Great Recession followed the 2008 housing crash and is commonly paired with discussions of the paradox of thrift and fiscal stimulus.

    • recessions — Recessions are periods of broad economic decline within the business cycle, often dated by the NBER as contractions in real activity. The Great Recession of 2007 to 2009 is the best-known recent example.

  • Aggregate demand / aggregate supply (AD-AS) model — AD slopes down; short-run AS (SRAS) slopes up; long-run AS (LRAS) is vertical at potential output.

  • IS-LM model — John Hicks’s formalization of Keynes: the IS curve (investment-saving equilibrium in goods market) and LM curve (liquidity preference-money supply equilibrium) jointly determine interest rates and output in the short run. It is also called the investment-saving/liquidity preference-money supply model; it plots income against interest rates. The Mundell-Fleming model extends it to an open economy.
    • the IS curve — This curve shows the negative relationship between interest rates and income in the goods market. It is commonly paired with the LM curve in the IS-LM model.

  • Keynesian cross — a simple model where output is determined by planned expenditure; equilibrium where the 45° line (output = income) intersects the aggregate expenditure function; illustrates the multiplier.

  • Multiplier effect — an initial change in spending is magnified through successive rounds of consumption; the multiplier = 1 / (1 − MPC), where MPC is the marginal propensity to consume. In macroeconomics, the related money-supply multiplier depends on banks’ reserve requirements.

  • Marginal propensity to consume (MPC) — the fraction of an additional dollar of income that is spent on consumption (the remainder is the marginal propensity to save, MPS); central to Keynesian multiplier analysis.
    • marginal propensity to consume — The marginal propensity to consume is the fraction of additional disposable income that is spent rather than saved. In Keynesian economics it is the slope of the consumption function and a key part of the spending multiplier.

  • Permanent income hypothesis — Milton Friedman: consumption is determined by permanent (long-run average) income, not current income; transitory income shocks are largely saved.

  • Macroeconomic models
    • open economy macroeconomics
      • Mundell-Fleming model — The Mundell-Fleming model extends IS-LM to open economies and is used to analyze output, interest rates, exchange-rate policy, and capital mobility. It is often presented with the impossible trinity of fixed exchange rates, free capital movement, and independent monetary policy.
• Stabilization, Expectations, and Policy Debates
  • Fiscal policy — government spending and taxation. Expansionary: increase G or cut T; contractionary: cut G or raise T. Subject to lags (recognition, legislative, implementation). It is often discussed in Keynesian terms, including fiscal stimulus during recessions, debates over Ricardian equivalence, and stimulus packages such as the ARRA.

    • Austerity — Austerity is contractionary fiscal policy that lowers deficits through spending cuts, tax increases, or both. It is especially associated with European debt-crisis bailouts and with arguments about reducing debt-to-GDP ratios.

    • crowding-out effect — The crowding-out effect is the tendency for government borrowing to push up interest rates and reduce private investment. It is often used to argue that expansionary fiscal policy may have less impact on total demand than expected.

    • deficit spending — Deficit spending is government spending in excess of revenue, a Keynesian response to downturns such as the Great Depression. It appears in economic debates over how states can stimulate demand when private consumption falls.

    • government spending — Government spending is the G in GDP and a central tool of Keynesian fiscal policy. It is associated with stimulus, crowding out, and debates over deficits, multipliers, and aggregate demand.

    • Tax cuts — Tax cuts are a fiscal policy tool often justified by supply-side arguments that claim lower taxes encourage investment and growth.

  • Fiscal multiplier — the change in output associated with a change in government spending or taxation; a government-purchases multiplier of 1 means one additional dollar of output per dollar of purchases. It need not exceed 1: its size depends on economic slack, monetary policy, financing, timing, and household or business responses.¹⁰ It is often discussed in the context of fiscal stimulus and recession policy, especially in Keynesian economics, where its size depends on monetary conditions, household behavior, and the state of the economy.

  • Automatic stabilizers — fiscal mechanisms that automatically dampen business cycles without new legislation: unemployment insurance, progressive income taxes.

  • Monetary policy — central bank actions to influence money supply and interest rates. Common tools include open market operations, reserve requirements, and the discount rate; it is contrasted with fiscal policy and is often discussed in connection with inflation, liquidity traps, and the Federal Reserve.
    • central banks — Central banks are the institutions that conduct monetary policy, control interest rates, and act as lenders of last resort. Examples include the Federal Reserve and the ECB, which use tools such as open-market operations, forward guidance, and dual mandates.

      • Bank of England — The central bank of the United Kingdom, associated with Threadneedle Street and nicknamed the “Old Lady of Threadneedle Street.” Its history includes the Restriction Act, the 1992 ERM crisis and George Soros’s currency speculation during Black Wednesday, and later operational independence in monetary policy.

      • European Central Bank — This Frankfurt-based institution sets monetary policy for the eurozone and is charged with maintaining price stability. It became fully operational in 1999 and is associated with the euro, HICP inflation targeting, and Mario Draghi’s “whatever it takes” pledge.

    • expansionary monetary policy — Expansionary monetary policy is a policy stance meant to increase aggregate demand. Central banks use it by lowering interest rates or otherwise making credit easier to spur spending and investment.

    • Friedman’s k-percent rule — Friedman’s k-percent rule is Milton Friedman’s proposal that a central bank should increase the money supply by a fixed percentage each year. The rule is designed to avoid procyclical monetary policy during business-cycle fluctuations.

    • Open market operations — Open market operations are the Federal Reserve’s purchases and sales of government securities to influence bank reserves and interest rates. They are a standard tool of monetary policy used to expand or contract the money supply.

    • Paul Volcker — Paul Volcker was the Federal Reserve chairman whose disinflation policy helped break the stagflation of the 1970s and early 1980s. The Volcker Rule later took his name as part of post-2008 banking regulation limiting proprietary trading.

    • quantitative easing — Quantitative easing is a central-bank policy that expands money supply by buying financial assets, especially government bonds, when interest rates are near zero. It is used to stimulate economies in liquidity traps by lowering long-term yields and supporting lending.

    • reserve requirement — The reserve requirement is the minimum amount of cash or reserves a bank must hold against deposits, or the fraction of deposits/assets it must keep on hand rather than lend out. It is set by a central bank such as the Federal Reserve as a monetary-policy tool to regulate liquidity and lending, help prevent bank runs, and restrain lending. Its reciprocal determines the money multiplier.

    • Seignorage — Seignorage is the profit a government or issuer earns from producing money. It is the gap between the face value of currency and the cost of making it.

    • Taylor rule — The Taylor rule is a monetary-policy guideline named for Stanford economist John Taylor. It advises central banks to set nominal interest rates in response to inflation and the output gap, especially by raising rates more than one-for-one when inflation rises.

  • Quantity theory of money — MV = PQ (Fisher equation of exchange): money supply (M) times velocity (V) equals price level (P) times real output (Q); if V and Q are stable, money growth drives inflation.

  • Lucas critique — Robert Lucas (1976): econometric models that ignore how agents adjust their behavior when policy changes are structurally invalid for policy evaluation; foundational to rational expectations macroeconomics.

  • Rational expectations — John Muth (1961), extended by Lucas and Sargent: agents form expectations using all available information and the correct model of the economy; on average, they are not systematically wrong. It underlies the Lucas critique and the policy ineffectiveness proposition in New Classical macroeconomics. In this view, consumers and firms anticipate fiscal and monetary policy changes and adjust their behavior accordingly, so policy surprises are often blunted by private decisions.

  • Real business cycle (RBC) theory — Kydland and Prescott (Nobel 2004): business cycles are efficient responses to real technology shocks; monetary policy is largely irrelevant; agents optimize intertemporally.

  • Natural rate of interest — the real interest rate consistent with potential output and stable inflation; a key concept in central bank policy (the “r-star”).

  • economic policies
    • Abenomics — Abenomics is the economic program associated with Shinzō Abe and his Liberal Democratic Party. Its “three arrows” combine monetary easing, fiscal stimulus, and structural reform, with later versions aiming at higher inflation, stronger growth, and broader social policy goals.
  • economic policy

    • laissez-faire — The economic doctrine favoring minimal or no government interference in markets, trade, and private business. The phrase comes from French, meaning “let it be,” and was popularized by physiocrats such as Vincent de Gournay. It is associated with classical economists such as Adam Smith and was later championed in politics by the Manchester school and its support for free trade. It is often contrasted with interventionist economic policy and the visible hand of the state.

    • mercantilism — Mercantilism is the early modern economic theory that treats trade as a zero-sum contest and urges states to accumulate bullion through regulation and favorable trade balances. Adam Smith and the Physiocrats criticized it as an obstacle to free trade and economic liberalism.
      • Thomas Mun — Thomas Mun was an English mercantilist writer who helped make balance-of-trade analysis central to economic thought. He wrote A Discourse of Trade and England’s Treasure by Forraign Trade, defending the export of specie and the East India Company’s trade.
    • Washington Consensus — The Washington Consensus is the label for the neoliberal policy package promoted by Washington-based institutions and economists like John Williamson. Its standard reforms include privatization, liberalization, austerity, and fiscal discipline, and it became a major target of Latin American critics in the 1990s.
  • economic reforms
    • Rogernomics — Rogernomics was the market-oriented reform program associated with New Zealand politician Roger Douglas in the 1980s. It cut subsidies, deregulated finance, and helped define the economic upheaval that followed the country’s turn away from heavy protectionism.
  • government budget deficits
    • U.S. budget deficit — The U.S. budget deficit is the amount the federal government spends above what it takes in through taxes. Its size has varied dramatically over time, including wartime peaks and a brief surplus period in the late 1990s and early 2000s.
  • Expectations

    • Adaptive expectations — Adaptive expectations are a model of forecasting in which people form beliefs about the future from past outcomes. In economics they appear in the Phillips curve and in cobweb models, where agents adjust behavior by extrapolating earlier prices or inflation.

    • inflation expectations — Inflation expectations are beliefs about how prices will change in the future, and they matter in models of the Phillips curve and monetary policy. Economists often measure them with surveys or compare nominal and real bond yields such as TIPS spreads.

  • fiscal — Fiscal is the adjective for government spending and taxation policy, as in fiscal policy, and it also describes a 12-month accounting year. The term appears in ideas like the fiscal multiplier and fiscal dominance in macroeconomics.

  • Ricardian equivalence — Barro: if consumers anticipate future taxes to repay deficit spending, they save the stimulus rather than spend it, neutralizing fiscal policy.
    • Ricardo’s theorem — Ricardo’s theorem is a claim associated with Ricardo-style reasoning about deficits and hidden future taxes. It is presented as an economic theorem asserting that current deficits are offset by future tax burdens.

  • Fiscal cliff — the simultaneous expiration of tax cuts and onset of spending cuts that would sharply tighten fiscal policy; a policy concept popularized during the U.S. 2012–2013 debate.

  • Liquidity trap — Keynes: when interest rates are near zero, monetary policy becomes ineffective because people hoard cash rather than invest; associated with Japan’s “lost decade” and post-2008 advanced economies. A Keynesian condition in which interest rates are so low that people prefer holding cash to investing, making monetary policy ineffective. It is associated with Japan’s lost decades and with proposals such as quantitative easing or commitments to future price-level or nominal GDP targets.

  • Animal spirits — Keynes’s term for the spontaneous urge to action that drives investment decisions, beyond purely rational calculation; revived by Akerlof and Shiller in Animal Spirits (2009). Akerlof and Shiller used the phrase in their 2009 work to explain confidence, fairness, and corruption as forces in markets.

  • Crowding out — government borrowing raises interest rates, reducing private investment; the offset reduces the net effect of fiscal stimulus. It is often discussed as a limit on expansionary fiscal policy when money demand is high or the LM curve is steep.

  • Supply-side economics — emphasizes cutting taxes (especially on high earners and capital) to stimulate investment and growth; associated with the Laffer curve and Reaganomics in the 1980s. It argues that lower marginal tax rates can expand the tax base by increasing work, saving, and investment, and that tax cuts can sometimes raise tax revenue as well as growth.

    • Jude Wanniski — Jude Wanniski was a journalist and author who coined the term supply-side economics and helped popularize the Laffer curve. He wrote The Way the World Works and argued for freer trade and a return to the gold standard.

    • Trickle-down — Trickle-down is a pejorative term for supply-side economics, especially the claim that tax cuts for the rich will eventually benefit everyone else. The phrase is closely associated with Reagan-era economic policy debates.

    • Trickle-down Economics — Trickle-down economics is the idea that tax breaks or benefits for the wealthy will eventually stimulate spending and help people lower down the social ladder. It is a pejorative label for supply-side policy.

    • Voodoo economics — Voodoo economics is the dismissive phrase George H. W. Bush used for Ronald Reagan’s supply-side tax-cut program. It is remembered as a political jab at trickle-down economics during the 1980 presidential campaign.

    • Panic of 1907 — The Panic of 1907 was a major American financial crisis triggered by the collapse of the Knickerbocker Trust Company and failed attempts to corner the copper market. J. P. Morgan and other financiers helped stem the panic, and the episode pushed reforms that eventually contributed to the Federal Reserve.
  • panics — Panics are sudden financial collapses often tied to bank runs, and they are commonly named for the year in which they occurred. Examples include the Panic of 1819, the Panic of 1837, the Panic of 1893, and the Panic of 1907, the last of which J.P. Morgan helped stabilize.
    • The Panic of 1819 — The Panic of 1819 was the first major economic crisis in United States history and a defining downturn of the Era of Good Feelings. It was tied to credit tightening, land speculation, and criticism of the Second Bank of the United States.

• Economic crises
  • Panics and depressions
    • Panic of 1893 — The Panic of 1893 was a severe American economic depression and major crisis during Grover Cleveland’s second term. It was tied to railroad failures, gold-reserve instability, and the Sherman Silver Purchase Act, and it produced severe unemployment and public agitation, including Coxey’s Army marching on Washington. Its political fallout helped shape the 1896 election.
• economic bubbles — Economic bubbles are speculative manias in which prices rise far above an asset’s intrinsic value. Famous examples include the South Sea Bubble, the Mississippi Bubble, the dot-com bubble, and the housing bubble that preceded the Great Recession.

  • irrational exuberance — Irrational exuberance is Alan Greenspan’s phrase for the speculative optimism that can drive stock prices far beyond underlying earnings or revenue. The term entered common usage after Greenspan used it in a 1996 speech about asset values that had seemingly risen too far.

  • Mississippi Company — The Mississippi Company was a French joint-stock company tied to John Law’s speculative bubble and the collapse of his financial system. Also called the Company of the West or Company of the Indies, it became notorious through the Mississippi Bubble.

  • The South Sea Bubble — The South Sea Bubble was the 1720 crash caused by speculation in the South Sea Company and its handling of British government debt. The bubble ruined many investors and ended the career of figures such as John Aislabie while helping shape the politics of Robert Walpole’s era.

Money and Central Banking

• Money supply measures (United States) — under the Federal Reserve definition used from May 2020, M1 includes currency held outside banks, demand deposits, and other liquid deposits, including savings deposits. M2 adds small-denomination time deposits and retail money-market fund balances, with specified retirement-account exclusions. Historical series must be read with their definitions: savings deposits were formerly outside M1.¹¹

• Federal Reserve (Fed) — U.S. central bank; primary tools: federal funds rate target, open market operations (buying/selling Treasuries), reserve requirements, discount rate, and (since 2008) interest on reserves.

• Fractional reserve banking — banks hold only a fraction of deposits as reserves; the rest is lent out, creating money. Money multiplier = 1 / reserve ratio (theoretical maximum). By expanding credit this way, it can increase the money supply, with reserve requirements setting the minimum cash cushion.

• Quantitative easing (QE) — large-scale asset purchases by central banks to expand reserves and lower long-term yields; used extensively after 2008 and in 2020.

• Zero lower bound — the constraint that nominal interest rates cannot fall much below zero; requires unconventional tools like QE or forward guidance.

• Lender of last resort — the central bank’s function of providing emergency liquidity to prevent bank runs; theorized by Bagehot. The IMF is described as playing this role internationally, while Hyman Minsky argued the Federal Reserve should act this way to limit financial crises.

• Gresham’s law — “bad money drives out good”: when two forms of currency are in circulation and one is undervalued, people hoard the better currency and spend the worse; attributed to Tudor financier Thomas Gresham. The principle was associated with Thomas Gresham and later used to explain the effects of debasement, bimetallism, and currency substitution, especially when both forms are legal tender.
  • Sir Thomas Gresham — An English Tudor/Elizabethan merchant and financier who served as a royal financial agent, helping manage royal debt and the currency of England. He founded the Royal Exchange and is best known for Gresham’s law: the idea that bad money drives good money out of circulation.

  • interest rate — Interest rates are the cost or price of borrowing money, usually discussed in nominal and real terms. They are central to monetary policy and finance models such as IS-LM and the Fisher equation, and are affected by central-bank policy and money demand. Related contexts include LIBOR, the federal funds rate, the TED spread, APR, liquidity traps, and the zero lower bound. A common rule of thumb for doubling time is the Rule of 72, which divides 72 by the rate.

    • Federal funds rate — The federal funds rate is the overnight interbank interest rate used by American banks to meet reserve requirements. It is one of the Federal Open Market Committee’s key policy targets and appears in Taylor rule discussions of monetary policy.

    • Fisher effect — The Fisher effect says that nominal interest rates move one-for-one with expected inflation. A related international version links exchange rates to the nominal interest rates of two countries.

    • interest — Interest is the fee or rate charged for borrowing money, usually expressed as a percentage of the principal. It appears in simple and compound forms, and central banks use related rates such as the federal funds rate to influence the economy.
      • Compound interest — Compound interest is interest earned on both the original principal and the accumulated interest from previous periods. Its exponential growth is often contrasted with simple interest, which is calculated only on principal.

    • London Interbank Offered Rate — The London Interbank Offered Rate (LIBOR) was a London benchmark interest rate for interbank lending, widely used as a reference point for short-term borrowing costs. It was commonly used to price adjustable-rate mortgages and other loans tied to dollar deposits between banks. LIBOR was also central to a major manipulation scandal and could be used in economic forecasting.

  • neutrality of money — The neutrality of money is the idea that changes in the money supply affect only nominal variables, not real output in the long run. It is a central claim of neoclassical monetary theory and is associated with economists such as Milton Friedman and Robert Lucas.

  • Quantity Theory of Money — The quantity theory of money links the money supply to price levels through the equation MV = PY, or related transaction-based forms. If velocity is stable, increases in money lead to proportional increases in the price level. It is associated with Simon Newcomb and Irving Fisher; the Fisher equation is often used to summarize it. Milton Friedman later revived this older monetary theory in modern macroeconomic debate.

  • transaction velocity of money — Transaction velocity of money is the rate at which money changes hands in an economy. It appears in the quantity equation and is often treated as a factor affecting price levels and monetary policy.

  • Velocity of money — The velocity of money is the rate at which money changes hands in an economy over a given period, usually measured as the average number of times a unit of currency is used in a year to purchase final goods and services. In the quantity theory of money it is written as V and appears in the equation MV = PY, often expressed as the ratio of nominal GDP to the money supply. The concept is associated with Irving Fisher’s monetary theory and later discussions by Keynes and monetarists.
• Monetary standards
  • free silver — Free silver was the late-19th-century demand that the United States coin silver freely rather than stay on a gold standard, a cause pushed by bimetallists and farmers and mocked in the gold-silver ratio slogan “16 to 1.” It appeared in the Populist and Democratic movements, was associated with the Bland-Allison and Sherman Silver Purchase Acts, and was effectively ended by the Gold Standard Act.

Related forms include historical media such as cowrie shells and rai stones, and topics like Gresham’s law, seigniorage, and foreign exchange markets.

    • Fiat money — Fiat money is currency with no intrinsic commodity value, whose worth rests on government backing, legal-tender status, and public trust. It is usually paper money rather than a commodity-backed standard, and is contrasted with commodity money. It is often discussed in relation to Gresham’s law and paper currency.

    • historical currencies

      • dinar — The dinar is a currency name used in several countries, including Jordan, Iraq, Libya, Algeria, North Macedonia, Sudan, and Kuwait. The name ultimately comes from the Latin denarius, a Roman silver coin, and in the Islamic world it also denoted a gold coin.

Magnitogorsk is often cited as a symbol of the first plan.
• Simon–Ehrlich wager
  • Julian Simon and Paul Ehrlich — Julian Simon and Paul Ehrlich are linked by the famous wager over whether the price of a basket of natural resources would rise or fall over the 1980s. Simon won the bet, which became a classic contrast between optimistic resource economics and population alarmism.

Its troubles drew takeover interest from Ford, GM, Fiat, DaimlerChrysler, and Hyundai. The group’s labor and restructuring crises included factory layoffs and the loss of most of its business units, leaving only a few divisions intact.
• Soviet economics
  • Scissors crisis — The scissors crisis was a Soviet economic imbalance in which industrial prices rose while agricultural prices fell, producing a graph shaped like open blades. It became a major problem under the New Economic Policy and pushed many peasants back toward subsistence farming.

• sustainability — Sustainability is the idea of meeting present needs without preventing future generations from meeting their own. It is associated with the Brundtland Report, triple bottom line accounting, and debates over development, conservation, and environmental policy.

• Well-being economics
  • Gross National Happiness — Gross National Happiness is Bhutan’s state-promoted measure of national well-being and quality of life, coined under Jigme Singye Wangchuck as an alternative to judging success by GNP alone. It tries to account for social and environmental wellbeing rather than focusing only on economic output, and its framework is associated with pillars such as economic self-reliance, democratic governance, environmental conservation, and cultural preservation.
• Economic growth models
  • Harrod-Domar model — The Harrod-Domar model is an early growth theory that links economic expansion to savings, investment, and the capital-output ratio. Independently developed by Harrod and Domar, it predicts that higher saving can produce faster GDP growth, unlike the later Solow-Swan approach.
• economic growth theory
  • Solow model — The Solow model is the standard neoclassical growth model used to discuss savings, capital accumulation, and steady-state output. It is especially associated with the golden-rule level of savings and with comparisons to Ramsey-Cass-Koopmans and IS-LM style macroeconomics.
• Growth accounting
  • Solow residual — The Solow residual is the portion of economic growth left unexplained by measured capital and labor inputs, often treated as total factor productivity. It is named for Robert Solow and is sometimes described as a measure of our ignorance in growth accounting.
• Growth economics
  • Technological growth — Technological growth is the increase in productivity driven by improvements in technology. In the Solow model, it is the long-run source of rising output per worker and can raise steady-state productivity permanently.
• growth models
  • Solow-Swan growth model — The Solow-Swan growth model is a neoclassical model of economic growth built around capital accumulation, labor, and exogenous technological progress. It predicts convergence to a balanced growth path and is associated with the golden rule and the Cobb-Douglas production function.
• Growth theory
  • endogenous growth theory — Endogenous growth theory explains long-run economic growth by treating technological progress and human capital as internal to the economy. It contrasts with the Solow model by emphasizing ideas, knowledge spillovers, and innovation as sources of sustained expansion.
    • New growth theory — New growth theory is a school of economics associated with Paul Romer that argues ideas and innovation, not just physical inputs, can sustain long-run growth. It treats knowledge creation as a key driver of growth that may persist indefinitely despite diminishing returns to material production.
  • Solow-Swan model — The Solow-Swan model is the standard neoclassical exogenous growth model in economics. It uses a Cobb-Douglas production function, emphasizes capital accumulation and technological change, and yields the golden-rule savings concept.
• productivity — Productivity is the economic measure of output per input, often discussed in total factor form as a residual after labor and capital are accounted for. It also appears in ecological uses such as gross and net primary productivity.
  • total factor productivity — Total factor productivity measures how efficiently an economy turns capital and labor into output. It is often written as a capital A in the Solow model and is approximated by growth-accounting residuals.
• Real economic growth — Real economic growth is the rise in real GDP per capita over time, meaning output increases after adjusting for inflation. It is associated with outward shifts of the production possibility curve, productivity gains, capital accumulation, technology, and endogenous-growth ideas tied to R&D and innovation. Solow-Swan and endogenous growth models explain it through capital accumulation, technology, and productivity, while Kaldor’s facts and Piketty’s work frame long-run patterns and inequality.

  • Economic growth rate — The economic growth rate measures the change in real GDP over time. It is the quantity that turns positive in expansions and negative during recessions, and it appears in models from Solow-Swan to Ramsey-Cass-Koopmans.

  • golden rule savings rate — The golden rule savings rate is the saving rate in the Solow model that maximizes steady-state consumption. Edmund Phelps associated it with the level of capital accumulation that gives the highest sustainable consumption.

  • savings rate — The savings rate is the share of income not spent on current consumption, a key variable in growth models from Harrod-Domar to Solow and Ramsey-Cass-Koopmans. It is also the object of the “golden rule” saving rate, which maximizes steady-state consumption.

• distribution of income
  • income inequality — Income inequality is the uneven distribution of money or wealth across a population, often summarized by the Gini coefficient and Lorenz curve. It is central to Kuznets-curve discussions of development and to arguments by Thomas Piketty and Joseph Stiglitz about capitalism and rent-seeking, and is sometimes described as the gap between the highest and lowest earners in a society.
• Inequality — Inequality can refer either to the mathematical relation using greater-than and less-than signs or to the uneven distribution of wealth in economics. Quizbowl clues often point to the Gini coefficient, the Lorenz curve, the Kuznets curve, and Thomas Piketty’s argument that returns on capital can widen wealth gaps.
  • Winner-Take-All Politics: How Washington Made the Rich Richer—and Turned Its Back on the Middle Class — Winner-Take-All Politics argues that rising U.S. inequality since the 1970s came largely from political choices rather than only market forces. The book contends that business influence turned Washington into a system of organized combat that concentrated gains among the wealthy.
• Inequality measures
  • Gini Coefficient or Gini Index — The Gini coefficient is a measure of income inequality based on the Lorenz curve. It ranges from 0 for perfect equality to 1 for perfect inequality and is widely used in economics and comparative politics.
• inequality metrics
  • Lorenz curve — This economics graph plots cumulative population share on the x-axis against cumulative income or wealth share on the y-axis, usually ordered from the poorest households upward. Perfect equality is shown by the line y = x, and the area between that line and the curve is used to compute the Gini coefficient. It is a standard way to visualize inequality in income distribution.
• ecological economics
  • steady-state economy — A steady-state economy is Herman Daly’s model of a green economy with a constant stock of wealth and a stable population. Nicholas Georgescu-Roegen argued that such an economy should even accept negative growth in order to conserve finite mineral resources.
• population economics

  • Malthusian trap — The Malthusian trap is a demographic and economic scenario in which population growth outpaces food supply or technological gains, keeping living standards or per-capita income near subsistence. The idea comes from Thomas Malthus’s theory of positive and preventive checks and is often discussed in relation to fertility, diminishing returns, overpopulation, stagnation, and long-run development.

  • Paul (Ralph) Ehrlich — Paul Ehrlich is a biologist and population writer best known for The Population Bomb, a controversial warning about an impending Malthusian catastrophe. He also appears in steady-state economics discussions and later coauthored Humanity on a Tightrope.

International Economics

• international economics

  • exchange rate — The ratio at which one currency can be exchanged for another, or the price of one currency in terms of another. It may be fixed, floating, or managed through regimes such as crawling pegs.

  • customs unions
    • Benelux Customs Union — The Benelux Customs Union was a wartime agreement among Belgium, the Netherlands, and Luxembourg. It was signed in London by governments in exile and later provided the basis for deeper economic cooperation among the three countries.
  • exchange rate regimes
    • fixed exchange rate — A fixed exchange rate is a currency regime in which a government pegs its currency to another currency or commodity such as gold. In the Mundell-Fleming model, it cannot coexist with both free capital mobility and an independent monetary policy.

  • foreign direct investment — Foreign direct investment is cross-border investment that gives the investor managerial control over a foreign company. It is often contrasted with portfolio flows and is encouraged through policy tools such as tax changes and bilateral investment treaties.

  • international trade — International trade is the exchange of goods and services across national borders. Clues may mention comparative advantage, the gravity model, Heckscher-Ohlin theory, Leontief’s paradox, or Paul Krugman’s new trade theory.

    • balance of trade — The balance of trade is a country’s exports minus its imports, also called net exports (NX). It is a component of the current account and is often discussed with the Marshall-Lerner condition, the J-curve, and mercantilist policy. As net exports, it measures the value of a nation’s exports minus its imports and is negative when the country runs a trade deficit.

    • comparative advantage — Comparative advantage is the economic principle that countries benefit from specializing in goods they can produce at lower opportunity cost and then trading for others. It is classically associated with David Ricardo and the example of English cloth and Portuguese wine.
      • Competitive Advantage — Competitive advantage is the condition in which a producer can make a good more efficiently or at a lower opportunity cost than a rival. The India-and-Pakistan willow example illustrates specialization based on differing relative efficiencies.

    • Dumping — Dumping is the practice of selling goods in a foreign market at below the home-market price, often described as predatory or unfair trade. In other contexts, the term can also mean disposing of large quantities of waste.

    • Eli Heckscher — Eli Heckscher was a Swedish economist best known for co-developing the Heckscher-Ohlin model of international trade with Bertil Ohlin. His work emphasized how differences in factor endowments shape comparative advantage and trade patterns.

    • exporting — Exporting is the activity of selling goods and services to other countries. It is the opposite of importing and is central to concepts such as trade balances, comparative advantage, and export-led growth.

    • Free trade — Free trade is the policy of reducing tariffs and other barriers to commerce. It is associated with the Cobden-Chevalier Treaty and with regional schemes such as CARIFTA and free-trade zones.
      • the Anti-Corn Law League — The Anti-Corn Law League was a British free-trade organization led by John Bright and Richard Cobden. It campaigned to repeal the Corn Laws, which imposed duties on imported grain.

    • law of comparative advantage — The law of comparative advantage says that countries should specialize in goods they can produce at lower opportunity cost, even if another country is absolutely more efficient. David Ricardo popularized the idea with examples such as England and Portugal trading cloth and wine.

    • Leontief paradox — The Leontief paradox is the empirical finding that the United States exported labor-intensive goods despite having a high capital-to-labor ratio. It challenged the Heckscher-Ohlin model of international trade.

    • maquiladoras — Maquiladoras are foreign-owned factories in Mexico that import parts or raw materials and export finished goods, especially along the U.S. border. They expanded under the Border Industrialization Program and grew rapidly after NAFTA.

    • Rybczynski theorem — The Rybczynski theorem says that increasing a factor endowment raises output in the good intensive in that factor. It is a standard result in Heckscher-Ohlin trade theory.

    • trade — Trade is the exchange of goods, services, or currency between parties, including international commerce governed by tariffs, comparative advantage, and organizations like the WTO. In historical clues it can refer to long-distance commercial networks such as the Hanseatic League or Mediterranean and spice trade routes. Economic questions often pair it with import, export, free trade, and comparative advantage.

    • trade deficit — A trade deficit occurs when a country imports more value than it exports. It is the opposite of a trade surplus and is often discussed in arguments over tariffs, mercantilism, and international trade balances.

    • Zollverein — The Zollverein was the German customs union founded in 1834 under Prussian leadership. It was inspired by Friedrich List and later became a key step toward German economic unification.
• Trade Models, Payments, and Exchange Rates

  • Absolute vs comparative advantage — absolute: can produce more with the same inputs. Comparative: can produce at lower opportunity cost. Countries gain from trade based on comparative advantage even if one has absolute advantage in all goods (Ricardo).

  • Heckscher-Ohlin model — countries export goods intensive in their abundant factors. Stolper-Samuelson theorem: trade benefits the abundant factor, harms the scarce factor. It explains comparative advantage through differences in countries’ factor endowments, especially labor and capital. It is associated with the Rybczynski result and the Leontief paradox.

    • Bertil Ohlin — Bertil Ohlin was a Swedish economist who shared the Nobel Prize with James Meade for work on international trade and finance. He is especially known for the Heckscher-Ohlin model and for writings on trade theory and stabilization policy.

    • Heckscher–Ohlin trade theory — Eli Heckscher developed the factor-endowment approach, which Bertil Ohlin extended in Interregional and International Trade (1933). In the standard model, countries export goods intensive in their relatively abundant factors. Ohlin shared the 1977 economics prize with James Meade.¹²

  • Terms of trade — the ratio at which a country’s exports exchange for imports; a deterioration means more exports needed per unit of imports.

  • Balance of payments — records all international transactions: current account (trade in goods/services, income transfers) + capital account + financial account = 0.

  • Current account deficit — imports exceed exports + net income; must be financed by capital inflows. The U.S. has run a persistent deficit since the 1980s.

  • Exchange rates — fixed (pegged): government holds rate via intervention. Floating: determined by market. Purchasing power parity (PPP): exchange rates equalize price levels; used for cross-country GDP comparisons. Exchange rates give the value of one currency in terms of another. Economists also relate them to interest rate parity and policy tools such as crawling pegs and Tobin taxes.

    • foreign exchange rates — Foreign exchange rates measure the value of one currency in terms of another and are central to questions of fixed pegs, capital mobility, and monetary policy trilemmas. They are also the target of uncovered interest parity arguments and carry-trade strategies, and real exchange rates are used in purchasing power parity calculations.

    • J-curve effect — The J-curve effect is the pattern in which a currency devaluation first worsens and then improves a country’s current account balance. It is commonly discussed in international economics as a lagged response to exchange-rate changes.

    • Purchasing power parity — Purchasing power parity is the economic idea that exchange rates should reflect relative price levels between countries. It compares currencies by asking how much of the same basket of goods each can buy in different countries, is tied to the Law of One Price, and is used to compare GDP across countries without distortions from exchange-rate swings. Purchasing power parity theory says exchange rates should move toward a long-run equilibrium when the same basket of goods costs the same in different countries; it is associated with Gustav Cassel and the idea that real exchange rates tend toward a constant over time. It is often illustrated with the Big Mac Index.
      • Big Mac Index — The Economist’s tongue-in-cheek measure of purchasing-power parity between currencies. It compares the price of a Big Mac in different countries and has been published annually since 1986. The index is named for McDonald’s Big Mac, the flagship burger used as the reference price.
    • real foreign exchange rate — The real foreign exchange rate measures how much one currency costs in terms of another. It is central to debates over pegs, floating regimes, sterilized intervention, and the impossible trinity in open-economy macroeconomics.

  • Stolper-Samuelson theorem — in the Heckscher-Ohlin framework, trade raises the real return to the abundant factor and lowers the real return to the scarce factor; explains why trade creates distributional winners and losers within countries.

  • Factor price equalization theorem — corollary of Heckscher-Ohlin: under idealized conditions, free trade equalizes factor prices (wages, capital returns) across countries.

  • Marshall-Lerner condition — a devaluation improves the current account only if the sum of import and export price elasticities exceeds 1. It says a currency devaluation improves the balance of payments only if the price elasticities of exports and imports sum to more than one. It is a standard result in exchange-rate economics and appears in discussions of fixed exchange-rate regimes and the Mundell-Fleming model.

  • J-curve — after devaluation, the trade balance initially worsens (existing contracts) before improving; traces a J shape.

In U.S. central banking, the term also refers to the interest rate the Federal Reserve charges member banks for short-term borrowing.

It is commonly divided into weak, semi-strong, and strong forms depending on what information is assumed to be reflected in prices; its semi-strong form says that no trading strategy using public information can reliably earn excess returns. It is associated with Eugene Fama and is often contrasted with behavioral finance and technical analysis.

  • option pricing models
    • Black-Scholes model — The Black-Scholes model is the standard formula for pricing European options and other derivatives under geometric Brownian motion, with no-arbitrage assumptions, constant volatility, and a known risk-free rate. It uses the underlying stock price, strike price, time to expiration, and related inputs to value stock options; the 1973 Black-Scholes formula was named for Fischer Black and Myron Scholes, with related work by Robert Merton. The model is associated with the volatility smile problem, which shows where the constant-volatility assumption breaks down, and it helped earn two of its creators the 1997 Nobel Prize in Economics. It also appears in applications ranging from insurance to corporate valuation.

  • risk — This economic quantity represents the possibility of loss or uncontrolled downside, and it appears in ideas like risk aversion, moral hazard, and liquidity risk. In finance it helps distinguish assets by volatility and by beta in the capital asset pricing model, and it is often reduced by diversification or hedging.

  • risk management
    • hedging — Hedging is a financial risk-management strategy that offsets potential losses by taking an opposite or protective position, such as buying a put option. It is the practice of taking offsetting positions so gains and losses cancel out if prices move.

Evidence, Economic Thought, and Key Economists

Connect economic claims and thinkers to evidence and models.

Empirical Methods and Causal Inference

Economic theory proposes mechanisms; empirical economics asks what the data identify about them. A correlation, a forecast, and a causal effect answer different questions.

• Identification — the assumptions and research design that connect an observed comparison to a quantity of interest, such as the effect of a policy. More observations can improve precision without removing confounding or selection bias.

• Randomized experiments — random assignment creates comparable treatment groups in expectation. The intention-to-treat effect concerns assignment; estimating the effect of treatment actually received requires addressing noncompliance. Random assignment does not itself guarantee generalization to other populations.

• Natural experiments — use circumstances that generate plausibly exogenous variation. Credibility depends on how exposure was assigned and which alternative explanations the design excludes. Card, Angrist, and Imbens were recognized by the 2021 economics prize for empirical and methodological work in this tradition.

• Difference-in-differences — compares changes over time between exposed and comparison groups. A central identifying assumption is that their untreated outcomes would have followed parallel trends; similar pre-intervention trends are useful evidence but cannot prove that counterfactual assumption.

• Instrumental variables — uses a variable that changes exposure while satisfying independence and exclusion assumptions. Under additional conditions, including monotonicity in the standard binary-instrument setting, the estimate can identify an effect for people whose exposure changes with the instrument; it need not equal the population-average effect. Instrumental variables are exogenous variables used to identify causal effects when a regressor is endogenous. They are common in two-stage least squares and natural-experiment designs, where validity depends on relevance and exclusion.

• Prediction and policy — a model that forecasts well within one setting may not identify the effects of an intervention. Report effect sizes and uncertainty, justify the comparison group, and distinguish local evidence from claims about different institutions or populations.¹³

• econometrics — Econometrics applies statistics and mathematics to economic data, often using regression, time-series methods, and OLS. It is associated with Ragnar Frisch, Trygve Haavelmo, the Cowles Commission, and tools like vector autoregression.

• economic methodology

  • Normative economics — Normative economics is the branch of economics concerned with value judgments about what the economy should be like. It contrasts with positive economics, which describes what is, rather than what ought to be.

  • Ceteris paribus — Ceteris paribus is the Latin phrase meaning “all else equal” or “all other things being equal.” Economics uses it to isolate the effect of one variable while holding other factors constant.

  • ex ante — Ex ante is a Latin phrase meaning “beforehand.” It is used for estimates or evaluations made before uncertain outcomes are resolved, especially in economics and policy analysis.

• Economics methodology
  • Positive economics — Positive economics studies how the economy actually works, using observation and analysis rather than prescription. It is contrasted with normative economics, which asks how the economy ought to be.

Schools of Thought

• Classical economics — Adam Smith, Ricardo, Mill; markets self-correct via price flexibility; laissez-faire; supply creates its own demand (Say’s law).

  • Iron Law of Wages — The classical economic claim that wages tend in the long run to fall to bare subsistence levels. It is associated with David Ricardo and later Ferdinand Lassalle, and was also used by Marx and by critics of capitalism and labor reform. It is often linked to Malthusian population pressure and was originally deployed against poor relief in Britain.

  • value — Value is the classical economic concept used in labor theory, exchange theory, and discussions of surplus value. In economics and linguistics alike, it can be treated as a relation defined by context, whether for prices in Marxian theory or for signs in Saussure’s system.

• Say’s law — “supply creates its own demand”: production generates sufficient income to purchase all output; implies no sustained general gluts; contested by Keynes, who argued demand deficiencies are possible. It is commonly attributed to Jean-Baptiste Say and is also called Say’s law of markets.

• Marxian economics — Marx; labor theory of value; surplus value extracted by capitalists; capitalism contains internal contradictions leading to crisis and eventual collapse. Key works: Das Kapital (vol. 1, 1867).

  • commodity fetishism — Commodity fetishism is Marx’s critique of capitalist exchange, in which social relations between people appear as relations between things. It is closely tied to reification and to the claim that commodities seem to have value in themselves rather than through labor.

  • surplus value — Surplus value, in Marxian economics, is the excess value produced by labor over the wage paid to the worker. Marx treats it as the source of capitalist profit and a key mechanism of exploitation in Das Kapital.

• Labor theory of value — the view (classical and Marxian) that the value of a commodity is determined by the socially necessary labor time required to produce it; Marx used it to analyze exploitation and surplus value. It appears in the writings of Adam Smith, David Ricardo, and Karl Marx. In Marxist versions, it is tied to the relation between exchange value and labor power, and later marginal productivity theory displaced it in economics.

• Keynesian economics — Keynes; aggregate demand drives output; markets can get stuck at below-full-employment equilibria; government spending can stimulate recovery. Key work: The General Theory (1936).

  • Keynesian school — The Keynesian school of economics argues that government policy should respond actively to stabilize recessions and fluctuations in demand. Its theorists include economists such as James Tobin, Robert Solow, and Franco Modigliani.

It is central to The General Theory of Employment, Interest, and Money, along with concepts like the multiplier, liquidity preference, and deficit spending.

  • interest-rate effect
    • Keynes’ interest-rate effect — The Keynesian interest-rate effect is the claim that a lower price level reduces interest rates, which encourages investment spending. That higher investment then raises aggregate demand for goods and services.

  • Keynesian — Keynesian economics argues that government fiscal policy can manage the business cycle by affecting aggregate demand. It is associated with sticky wages and prices and with public works spending to reduce unemployment.

  • paradox of thrift — The paradox of thrift is the idea that when everyone becomes more frugal at once, aggregate income can fall even though individual saving intentions rise. It is associated with Keynes and appears in examples such as the Capital Hill Babysitting Co-op and Mandeville’s The Fable of the Bees.

• Neoclassical synthesis — post-WWII merging of Keynesian macro with neoclassical micro (Samuelson, Hicks, Modigliani).

• Monetarism — Milton Friedman; money supply growth is the primary determinant of nominal GDP and inflation; stable money-growth rules preferred over discretionary policy. Key work: A Monetary History of the United States (1963, with Anna Schwartz). It is associated with Milton Friedman and Anna Schwartz and is often summarized as holding that steady control of the money supply is the key to inflation and business cycles; it also argues against activist fiscal policy in favor of predictable monetary growth.

• Rational expectations / New Classical — Lucas, Sargent; agents use all available information to form expectations; anticipated policy is ineffective (policy ineffectiveness proposition).

• New Keynesian — Mankiw, Romer; incorporates rational expectations but retains price stickiness and market failures; provides microfoundations for Keynesian results.
