Joseph Stiglitz, george akerlof, and michael spence shared the 2001 Nobel Prize “for their analyses of markets with asymmetric information.” The particular market with asymmetric information that Stiglitz analyzed was the insurance market. In 1976, Stiglitz and coauthor Michael Rothschild started from the plausible assumption that people buying insurance know more about their relevant characteristics […]| Econlib
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
Ludwig von Mises was one of the last members of the original austrian school of economics. He earned his doctorate in law and economics from the University of Vienna in 1906. One of his best works, The Theory of Money and Credit, was published in 1912 and was used as a money and banking […]| 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
To economists, efficiency is a relationship between ends and means. When we call a situation inefficient, we are claiming that we could achieve the desired ends with less means, or that the means employed could produce more of the ends desired. “Less” and “more” in this context necessarily refer to less and more value. Thus, […]| 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
Socialism—defined as a centrally planned economy in which the government controls all means of production—was the tragic failure of the twentieth century. Born of a commitment to remedy the economic and moral defects of capitalism, it has far surpassed capitalism in both economic malfunction and moral cruelty. Yet the idea and the ideal of socialism […]| Econlib
Economists approach the analysis of crime with one simple assumption—that criminals are rational. A mugger is a mugger for the same reason I am an economist—because it is the most attractive alternative available to him. The decision to commit a crime, like any other economic decision, can be analyzed as a choice among alternative combinations […]| Econlib
One of the most important building blocks of economic analysis is the concept of demand. When economists refer to demand, they usually have in mind not just a single quantity demanded, but a demand curve, which traces the quantity of a good or service that is demanded at successively different prices. The most famous law […]| 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
If any twentieth-century economist was a Renaissance man, it was Friedrich Hayek. He made fundamental contributions in political theory, psychology, and economics. In a field in which the relevance of ideas often is eclipsed by expansions on an initial theory, many of his contributions are so remarkable that people still read them more than fifty […]| Econlib
