People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices. It is impossible indeed to prevent such meetings, by any law which either could be executed, or would be consistent with liberty and justice. But […]| Econlib
Ronald Coase received the Nobel Prize in 1991 “for his discovery and clarification of the significance of transaction costs and property rights for the institutional structure and functioning of the economy.” Coase is an unusual economist for the twentieth century, and a highly unusual Nobel Prize winner. First, his writings are sparse. In a […]| Econlib
Gunnar Myrdal, a Swedish economist, made an international reputation with his 1944 book, An American Dilemma, today considered a classic in sociology. The book was the end product of a study that the Carnegie Corporation had commissioned about what was then called the “Negro question.” Myrdal’s damning critique of the “separate but equal” doctrine […]| Econlib
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 […]| Econlib
Origins Before 1890, the only “antitrust” law was the common law. Contracts that allegedly restrained trade (e.g., price-fixing agreements) often were not legally enforceable, but they did not subject the parties to any legal sanctions, either. Nor were monopolies illegal. Economists generally believe that monopolies and other restraints of trade are bad because they usually […]| Econlib
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 […]| 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
With The Wealth of Nations Adam Smith installed himself as the leading expositor of economic thought. Currents of Adam Smith run through the works published by David Ricardo and Karl Marx in the nineteenth century, and by John Maynard Keynes and Milton Friedman in the twentieth. Adam Smith was born in a small village […]| 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
Public choice applies the theories and methods of economics to the analysis of political behavior, an area that was once the exclusive province of political scientists and sociologists. Public choice originated as a distinctive field of specialization a half century ago in the works of its founding fathers, Kenneth Arrow, Duncan Black, James Buchanan, Gordon […]| 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
