The foreign exchange market is the market in which foreign currency—such as the yen or euro or pound—is traded for domestic currency—for example, the U.S. dollar. This “market” is not in a centralized location; instead, it is a decentralized network that is nevertheless highly integrated via modern information and telecommunications technology. According to a triennial […]
The Library of Economics and Liberty carries the popular Concise Encyclopedia of Economics, edited by David R. Henderson.
This highly acclaimed economics encyclopedia was first published in 1993 under the title The Fortune Encyclopedia of Economics. It features easy-to-read articles by over 150 top economists, including Nobel Prize winners, over 80 biographies of famous economists, and many tables and charts illustrating economics in action. With David R. Henderson’s permission and encouragement, the Econlib edition of this work includes links, additions, and corrections.
Investment is one of the most important variables in economics. On its back, humans have ridden from caves to skyscrapers. Its surges and collapses are still a primary cause of recessions. Indeed, as can be seen in Figure 1, investment has dropped sharply during almost every postwar U.S. recession. As the graph suggests, one cannot […]
Economic competition takes place in markets—meeting grounds of intending suppliers and buyers.1 Typically, a few sellers compete to attract favorable offers from prospective buyers. Similarly, intending buyers compete to obtain good offers from suppliers. When a contract is concluded, the buyer and seller exchange property rights in a good, service, or asset. Everyone interacts voluntarily, […]
Positive externalities are benefits that are infeasible to charge to provide; negative externalities are costs that are infeasible to charge to not provide. Ordinarily, as Adam Smith explained, selfishness leads markets to produce whatever people want; to get rich, you have to sell what the public is eager to buy. Externalities undermine the social benefits […]
Until the so-called Keynesian revolution of the late 1930s and 1940s, the two main parts of economic theory were typically labeled “monetary theory” and “price theory.” Today, the corresponding dichotomy is between “macroeconomics” and “microeconomics.” The motivating force for the change came from the macro side, with modern macroeconomics being far more explicit than old-fashioned […]
This category ranges widely over various government policies, but mainly covers economy-wide policies on taxes, government spending, government debt and deficits, redistribution, welfare, and monetary policy.
With the decline in transportation costs, especially across oceans, and the recent increase in trade barriers, topics in international trade has become even more important.
Sometimes defined as the theory of the economy as a whole, macroeconomics includes issues such as economic growth, fiscal policy, monetary policy, national income accounts, and unemployment.
Partly because of the economy-wide effects of money and banking, and partly because of the specific government policies that regulate the money supply and banking, there is a separate category to cover those issues. The entries include bank runs, the Federal Reserve system, and the Savings and Loan crisis.
More than any other economist, Paul Samuelson raised the level of mathematical analysis in the profession. Until the late 1930s, when Samuelson started his stunning and steady stream of articles, economics was typically understood in terms of verbal explanations and diagrammatic models. Samuelson wrote his first published article, “A Note on the Measurement of […]
In 2003, econometrician Clive Granger, along with econometrician Robert Engle, received the Nobel Prize in economics. Granger’s award was “for methods of analyzing economic time series with common trends (cointegration).” Trained in statistics, Granger specializes in the behavior of time-series data (i.e., data that are recorded in calendar sequence, annually or at shorter or longer […]
