More than a century after his death, Karl Marx remains one of the most controversial figures in the Western world. His relentless criticism of capitalism and his corresponding promise of an inevitable, harmonious socialist future inspired a revolution of global proportions. It seemed that—with the Bolshevik revolution in Russia and the spread of communism throughout […]| Econlib
Abba Lerner was the milton friedman of the left. Like Friedman, Lerner was a brilliant expositor of economics who was able to make complex concepts crystal clear. Lerner was also an unusual kind of socialist: he hated government power over people’s lives. Like Friedman, he praised private enterprise on the ground that “alternatives to government […]| Econlib
Keynesian economics is a theory of total spending in the economy (called aggregate demand) and its effects on output and inflation. Although the term has been used (and abused) to describe many things over the years, six principal tenets seem central to Keynesianism. The first three describe how the economy works. 1. A Keynesian believes […]| Econlib
The Austrian school of economics was founded in 1871 with the publication of Carl Menger’s Principles of Economics. menger, along with william stanley jevons and leon walras, developed the marginalist revolution in economic analysis. Menger dedicated Principles of Economics to his German colleague William Roscher, the leading figure in the German historical school, which dominated economic […]| Econlib
Following the end of the Allied occupation of Japan, real increases in GNP averaged 9.6 percent from 1952 to 1971. From 1972 to 1991, growth remained strong but less dramatic, averaging 4 percent per year. The rest of the 1990s and early 2000s have been a different story. From 1991 to 2003, real economic growth […]| 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
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
When you buy a good or service, you rarely have perfect knowledge of its quality and safety. You are justifiably concerned about getting “ripped off.” Thus the need for consumer protection. Economic activity flourishes when consumers can trust producers, but the consumer must have grounds for trust. Consumers value, then, not only quality and safety, […]| Econlib
Most of the energy consumed in America today is produced from the combustion of fossil fuels, primarily oil, coal, and natural gas. Energy can be generated, however, in any number of ways. Figure 1 indicates the sources of energy employed by the American economy as of February 2004. Figure 1 U.S. Energy Sources, 2004 The economy […]| Econlib
“ Innovation”: creativity; novelty; the process of devising a new idea or thing, or improving an existing idea or thing. Although the word carries a positive connotation in American culture, innovation, like all human activities, has costs as well as benefits. These costs and benefits have preoccupied economists, political philosophers, and artists for centuries. Nature […]| 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
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
Joseph Schumpeter (1883–1950) coined the seemingly paradoxical term “creative destruction,” and generations of economists have adopted it as a shorthand description of the free market’s messy way of delivering progress. In Capitalism, Socialism, and Democracy (1942), the Austrian economist wrote: The opening up of new markets, foreign or domestic, and the organizational development from the […]| Econlib
