Take the 100-question quizIn a market economy, what primarily determines the price of goods and services?
The interaction of supply and demand sets prices: when buyers want more than sellers offer, prices climb; when goods pile up unsold, they fall. No planner needs to set them.
Which of the following is a fundamental characteristic of a capitalist economic system?
Capitalism is an economic system defined by private individuals or businesses owning and controlling the means of production, with the primary goal of generating profits. Free markets and competition are also key aspects.
What does Gross Domestic Product (GDP) measure?
Gross Domestic Product (GDP) is a monetary measure of the total market value of all the final goods and services produced within a country's borders during a specific time period, usually a year or a quarter. It is a key indicator of economic activity and health.
In economics, what is the 'opportunity cost' of a decision?
The value of the best alternative forgone is the opportunity cost: the true price of a choice is the next-best thing you gave up to make it.
John Maynard Keynes's 'The General Theory of Employment, Interest and Money' was published in which year?
The General Theory appeared in February 1936, in the shadow of the Great Depression; it denied that an economy automatically returns to full employment and gave macroeconomics much of its vocabulary.
Who completed and published volumes II and III of Marx's 'Das Kapital' from his manuscripts?
Friedrich Engels assembled volumes II and III from Marx's manuscripts and published them in 1885 and 1894, more than a decade after his collaborator's death; volume I had appeared in 1867.
Which institution created the economics prize awarded with the Nobels in 1968, marking its 300th anniversary?
Founded in 1668, the Riksbank is the world's oldest surviving institution of its kind; the prize was first awarded in 1969 to Jan Tinbergen and Ragnar Frisch.
Which economic system blends private enterprise with government intervention?
A mixed economy is what almost every modern country runs: markets do most of the allocating while the state regulates, provides public services and redistributes income.
What financial metric is the cost of borrowing money, usually expressed as a percentage?
Interest rates are a fundamental component of financial markets, influencing everything from mortgages and loans to savings accounts and investments.
What occurs when a government's total expenditures exceed its total revenues over a specific period?
A budget deficit means the government spent more than it took in that year; the national debt is the pile of past deficits it still owes.
In trade theory, what describes a country producing a good more efficiently than another country?
The idea was first set out in the context of international trade in 1776, using labor as the only input, and it explains trade only when each side is outright better at making something.
What principle says countries should specialise where their opportunity cost is lowest, even if less efficient overall?
Comparative advantage, set out by David Ricardo in 1817, says a country gains by specialising where its opportunity cost is lowest even if it is worse at everything; it is often called economics' most counter-intuitive insight.
Which market structure has a single seller, high barriers to entry and strong pricing power?
A monopoly is one seller with no close substitutes, so it sets prices rather than accepting them; the board game of the same name began as a lesson in its dangers.
What is a downturn of two consecutive quarters of falling GDP commonly called?
A recession is a broad decline in economic activity; the popular rule of thumb is two consecutive quarters of falling real GDP, though the US NBER dates recessions using a wider set of indicators.
Which publication has published the tongue-in-cheek Big Mac Index since 1986?
The Economist introduced the Big Mac Index in September 1986 as a light-hearted test of purchasing power parity: if exchange rates were right, the same burger would cost the same everywhere.
Which economic school advocates minimal government intervention, holding that free markets naturally yield efficiency?
Classical economics emphasizes the self-regulating nature of markets and advocates for 'laissez-faire' policies, with limited government interference.
What term describes average cost per unit falling as production of a good increases?
Economies of scale are cost advantages reaped by companies when production becomes efficient, meaning the cost per unit of output decreases with increasing scale.
What do economists call something both non-excludable and non-rivalrous?
Public goods are characterized by non-excludability (it's hard to prevent people from using them) and non-rivalry (one person's use doesn't reduce availability for others).
Which institution is typically responsible for setting a country's monetary policy, chiefly through interest rates?
The central bank manages the money supply and interest rates, and is usually kept at arm's length from politicians so it can make unpopular decisions.

The arrangement ended on 15 August 1971, when the United States suspended the dollar's convertibility to gold, and the Jamaica Accords formally ratified its demise in 1976.
Which graph rests on the idea that a 0% or 100% tax rate raises no revenue?
The Laffer curve, named by Jude Wanniski in 1978 after economist Arthur Laffer, holds that tax revenue is zero at both 0% and 100% rates and peaks in between, so raising rates past the peak shrinks the take.
Which graph plots the income share of the bottom x percent of households against x?
It was devised by Max O. Lorenz in 1905; the further it sags below the 45-degree line of perfect equality, the more unequal the distribution.
When a government increases spending or cuts taxes to stimulate the economy, what is it doing?
Expansionary fiscal policy means spending more or taxing less to lift demand; the monetary version is the central bank's job, done through interest rates.
What is a staple called when people buy more of it as it gets dearer, because they can no longer afford alternatives?
A Giffen good is a staple whose demand rises with its price; Alfred Marshall's example, credited to Robert Giffen, was bread among the very poor, who drop meat and buy even more bread when bread gets dearer.
Which behavioral-economics concept describes preferring to avoid losses over acquiring equivalent gains?
Loss aversion makes a loss feel roughly twice as painful as an equal gain feels good, which is why streaks and sunk deposits are such effective motivators.
What type of unemployment comes from a mismatch between workers' skills and available jobs?
Structural unemployment arises when workers' skills do not match the jobs on offer, as when laid-off miners cannot fill local software vacancies; unlike cyclical unemployment it persists through recoveries.
What shows the combinations of two goods that give a consumer the same utility?
An indifference curve is a graph showing various combinations of two goods or commodities that give the consumer equal satisfaction or utility.
Which curve says that in the short run, lower unemployment comes with higher inflation?
The Phillips curve, drawn by A. W. Phillips in 1958 from a century of UK wage and unemployment data, pairs low unemployment with high inflation; the 1970s, when both rose together, broke the short-run pattern.
What is a luxury item called when raising its price increases demand for it?
A Veblen good sells better the dearer it gets, because the price is the point; Thorstein Veblen called the motive conspicuous consumption, and the demand curve slopes upward.
What is the term for a tax imposed on imported goods and services?
A tariff is a tax levied on imported goods or services, typically to protect domestic industries or generate revenue.

The Federal Reserve Act of 1913 followed the severe banking panic of 1907; the Fed's mandate is maximum employment, stable prices and moderate long-term interest rates.
What is it called when producing or consuming a good imposes a cost or benefit on an uninvolved third party?
Externalities are costs or benefits landing on people who never agreed to them, like factory smoke or a neighbour's beehives, which is why markets left alone misprice them.
What game-theory term describes each player's strategy being the best response to all the others'?
A Nash equilibrium is a standoff where nobody gains by changing strategy alone; John Nash's 1950 idea won him a Nobel and a biopic, A Beautiful Mind.
Which of the following is considered one of the four main factors of production?
The four main factors of production in economics are land, labor, capital, and entrepreneurship, which are the resources used to produce goods and services.
What coefficient, ranging from 0 to 1, is commonly used to measure income inequality within a nation?
The Gini coefficient is a measure of statistical dispersion intended to represent the income or wealth distribution of a nation's residents, with 0 representing perfect equality and 1 representing perfect inequality.
Which theory says economic agents decide using the best forecasts from all available information?

Rising prices plus rising unemployment, a pairing theory ruled out: what's the term?
Slow growth, high unemployment and rising prices at once. The Phillips Curve, which trades unemployment off against inflation, said the last two shouldn't rise together.
What term describes taking on more risk because someone else, such as an insurer, will bear the cost?
Moral hazard is extra risk-taking when someone else bears the cost: an insured firm may act more recklessly knowing its policy will pay, and banks rescued in 2008 were accused of it after their bailouts.
Which measure gives the percentage change in quantity demanded when a good's cost rises 1%?
Price elasticity of demand is the percentage change in quantity demanded divided by the percentage change in price; insulin, with few substitutes, is inelastic, while goods with many alternatives see demand swing sharply.
What type of cost does not vary with the level of output in the short run?
Fixed cost stays put whatever you produce, like rent or insurance; variable cost rises with every extra unit made.
Which principle says adding more of a variable input to a fixed input eventually lowers its marginal product?
The law of diminishing returns states that in a production process, adding more of one factor of production, while holding others constant, will eventually lead to smaller increases in output.
What concept is the total goods and services demanded across an economy at a given price level?
Aggregate demand represents the total demand for all finished goods and services produced in an economy at a given overall price level and in a given time period.
Who developed the theory of 'creative destruction', where innovation kills old industries?
Schumpeter developed the idea in 'Capitalism, Socialism and Democracy' (1942) out of a close reading of Marx, and it is sometimes called Schumpeter's gale.
What economic concept refers to the knowledge, skills and attributes embodied in individuals?
Human capital refers to the economic value of a worker's experience and skills. This includes assets like education, training, intelligence, and other abilities.
The 'tragedy of the commons' is the classic failure associated with which category of good?
Common-pool resources such as fisheries, forests and groundwater basins are hard to fence off yet rivalrous, so each catch leaves less for others; Garrett Hardin's 1968 essay named their overuse the tragedy of the commons.
Adam Smith's The Wealth of Nations was first published in which year?
The Wealth of Nations appeared on 9 March 1776, a few months before the American Declaration of Independence; David Hume wrote that he had feared it required too much thought to be popular.
Thomas Malthus's 1798 essay warned that what would outgrow a nation's food supply?
