The United States and all other modern industrial economies experience significant swings in economic activity. In some years, most industries are booming and unemployment is low; in other years, most industries are operating well below capacity and unemployment is high. Periods of economic prosperity are typically called expansions or booms; periods of economic decline are […]| Econlib
What Is the Money Supply? The U.S. money supply comprises currency—dollar bills and coins issued by the Federal Reserve System and the U.S. Treasury—and various kinds of deposits held by the public at commercial banks and other depository institutions such as thrifts and credit unions. On June 30, 2004, the money supply, measured as the […]| Econlib
Fiscal policy is the use of government spending and taxation to influence the economy. When the government decides on the goods and services it purchases, the transfer payments it distributes, or the taxes it collects, it is engaging in fiscal policy. The primary economic impact of any change in the government budget is felt by […]| Econlib
Edmund S. Phelps was awarded the 2006 Nobel Prize in economic science “for his analysis of intertemporal tradeoffs in macroeconomic policy.” He focused on two distinct areas of macroeconomics: the tradeoff between unemployment and inflation and capital accumulation and economic growth. In the early 1960s, many economists believed that the tradeoff between unemployment and inflation […]| Econlib
Milton Friedman was the twentieth century’s most prominent advocate of free markets. Born in 1912 to Jewish immigrants in New York City, he attended Rutgers University, where he earned his B.A. at the age of twenty. He went on to earn his M.A. from the University of Chicago in 1933 and his Ph.D. from […]| 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
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
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
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
