Michael Spence, along with george akerlof and joseph stiglitz, received the 2001 Nobel Prize “for their analyses of markets with asymmetric information.” Spence’s particular focus was on information about workers’ productivity. Assuming that a worker knows more about his productivity than a potential employer knows, Spence showed how it can make sense for highly […]| Econlib
New Keynesian economics is the school of thought in modern macroeconomics that evolved from the ideas of John Maynard Keynes. Keynes wrote The General Theory of Employment, Interest, and Money in the 1930s, and his influence among academics and policymakers increased through the 1960s. In the 1970s, however, new classical economists such as Robert Lucas, […]| Econlib
Paul Volcker, while chairman of the Board of Governors of the federal reserve system (1979–1987), was often called the second most powerful person in the United States. Volcker and company triggered the “double-dip” recessions of 1980 and 1981–1982, vanquishing the double-digit inflation of 1979–1980 and bringing the unemployment rate into double digits for the first […]| Econlib
The Birth of the “Blues” In the 1930s and 1940s, a competitive market for health insurance developed in many places in the United States. Typically, premiums tended to reflect risks, and insurers aggressively monitored claims to keep costs down and prevent abuses. Following World War II, however, the market changed radically. Hospitals had created Blue […]| Econlib
Few economic indicators are of more concern to Americans than unemployment statistics. Reports that unemployment rates are dropping make us happy; reports to the contrary make us anxious. But just what do unemployment figures tell us? Are they reliable measures? What influences joblessness? How Is Unemployment Defined and Measured? Each month, the federal government’s Bureau […]| Econlib
In recent years, taxation has been one of the most prominent and controversial topics in economic policy. Taxation has been a principal issue in every presidential election since 1980—with a large tax cut as a winning issue in 1980, a pledge of “Read my lips: no new taxes” in the 1988 campaign, and a statement […]| Econlib
The rate of interest measures the percentage reward a lender receives for deferring the consumption of resources until a future date. Correspondingly, it measures the price a borrower pays to have resources now. Suppose I have $100 today that I am willing to lend for one year at an annual interest rate of 5 percent. […]| Econlib
Saving means different things to different people. To some, it means putting money in the bank. To others, it means buying stocks or contributing to a pension plan. But to economists, saving means only one thing—consuming less out of a given amount of resources in the present in order to consume more in the future. […]| Econlib
Insurance plays a central role in the functioning of modern economies. Life insurance offers protection against the economic impact of an untimely death; health insurance covers the sometimes extraordinary costs of medical care; and bank deposits are insured by the federal government (see financial regulation). In each case, the insured pays a small premium in […]| Econlib
“ Free market” is a summary term for an array of exchanges that take place in society. Each exchange is undertaken as a voluntary agreement between two people or between groups of people represented by agents. These two individuals (or agents) exchange two economic goods, either tangible commodities or nontangible services. Thus, when I buy […]| Econlib
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, […]| Econlib
Since about 1970, an important strand of economic research, sometimes referred to as information economics, has explored the extent to which markets and other institutions process and convey information. Many of the problems of markets and other institutions result from costly information, and many of their features are responses to costly information. Many of the […]| Econlib
George Akerlof, along with Michael Spence and Joseph Stiglitz, received the 2001 Nobel Prize “for their analyses of markets with asymmetric information.” Although much of economics is built on the assumption of perfect information, various economists in the past had considered the effects of imperfect information. Two giants in this area were ludwig von […]| Econlib
