For well over a hundred years, the economic world has been engaged in a great intellectual debate. On one side of this debate have been those philosophers and economists who advocate an economic system based on private property and free markets—or what one might call economic freedom. The key ingredients of economic freedom are personal […]| 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
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
Economists use the term “inflation” to denote an ongoing rise in the general level of prices quoted in units of money. The magnitude of inflation—the inflation rate—is usually reported as the annualized percentage growth of some broad index of money prices. With U.S. dollar prices rising, a one-dollar bill buys less each year. Inflation thus […]| 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
Modern economists excel at identifying theoretical reasons why markets might fail. While these theories may temper uncritical views of the market, it is important to note that markets do, in fact, work incredibly well. Indeed, markets work so thoroughly and quietly that their success too often goes unnoticed. Consider that the number of different ways […]| Econlib
Compound Rates of Growth In the modern version of an old legend, an investment banker asks to be paid by placing one penny on the first square of a chessboard, two pennies on the second square, four on the third, etc. If the banker had asked that only the white squares be used, the initial […]| Econlib
In a capitalistic society, profits—and losses—hold center stage. Those who own firms (the capitalists) choose managers who organize production efforts so as to maximize their income (profits). Their search for profits is guided by the famous “invisible hand” of capitalism. When profits are above the normal level, they attract additional investment, either by new firms […]| 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
Businesses complain about regulation incessantly, but many citizens, consumer advocates, and nongovernmental organizations (NGOs) think it absolutely necessary to protect the public interest. What is regulation? Why do we have it? How has it changed? This article briefly provides some answers, concentrating on experience with regulation in the United States. Regulation consists of requirements the […]| Econlib
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 […]| 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
When asked by mathematician Stanislaw Ulam whether he could name an idea in economics that was both universally true and not obvious, economist Paul Samuelson’s example was the principle of comparative advantage. That principle was derived by David Ricardo in his 1817 book, Principles of Political Economy and Taxation. Ricardo’s result, which still holds up […]| Econlib
