Inflation is a sustained increase in the aggregate price level. Hyperinflation is very high inflation. Although the threshold is arbitrary, economists generally reserve the term “hyperinflation” to describe episodes when the monthly inflation rate is greater than 50 percent. At a monthly rate of 50 percent, an item that cost $1 on January 1 would […]| Econlib
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
Robert Lucas was awarded the 1995 Nobel Prize in economics “for having developed and applied the hypothesis of rational expectations, and thereby having transformed macroeconomic analysis and deepened our understanding of economic policy.” More than any other person in the period from 1970 to 2000, Robert Lucas revolutionized macroeconomic theory. His work led directly […]| 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
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
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

Economist Knut Wicksell made his name among the Swedish public with a series of provocative lectures on the causes of prostitution, drunkenness, poverty, and overpopulation. A malthusian, the young Wicksell advocated birth control as the cure for these social ills. His image as a radical social reformer did much to attract the attention of the […]| Econlib
Eugen von Böhm-Bawerk was one of the leading members of the Austrian school of economics—an approach to economic thought founded by Carl Menger and augmented by Knut Wicksell, Ludwig von Mises, Friedrich A. Hayek, and Sir John Hicks. Böhm-Bawerk’s work became so well known that before World War I, his Marxist contemporaries regarded the Austrians […]| 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
Junk bonds, also known less pejoratively as high-yield bonds, are bonds that are rated as “speculative” or “below investment” grade issues: below BBB for bonds rated by Moody’s and below Baa for bonds rated by Standard and Poor’s (the two main debt-rating agencies). Bond ratings measure the perceived risk that the bonds’ issuer will not […]| Econlib
The foreign exchange market is the market in which foreign currency—such as the yen or euro or pound—is traded for domestic currency—for example, the U.S. dollar. This “market” is not in a centralized location; instead, it is a decentralized network that is nevertheless highly integrated via modern information and telecommunications technology. According to a triennial […]| Econlib
Years later, the extraordinary cost of the 1980s S&L crisis still astounds many taxpayers, depositors, and policymakers. The cost of bailing out the Federal Savings and Loan Insurance Corporation (FSLIC), which insured the deposits in failed S&Ls, may eventually exceed $160 billion. At the end of 2004, the direct cost of the S&L crisis to […]| Econlib
Intellectual property is normally defined as the set of products protected under laws associated with copyright, patent, trademark, industrial design, and trade secrets. The U.S. Constitution expressly allows for intellectual property protection, albeit for a limited time, in the form of protection of “writings and discoveries” in order to promote “science and useful arts.” This […]| Econlib
The European Union (EU) includes twenty-seven countries and 490 million people. In 2005, the EU had a $13 trillion (€11 trillion) economy, a single market, and for some member countries, a single currency. A growing number of political and economic decisions are made on a pan-European level in Brussels. The origins of the EU are […]| 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
Bankruptcy is common in America today. Notwithstanding two decades of largely uninterrupted economic growth, the annual bankruptcy filing rate has quintupled, topping 1.5 million individuals annually. Recent years also have seen several of the largest and most expensive corporate bankruptcies in history. This confluence of skyrocketing personal bankruptcies in a period of prosperity, an increasingly […]| Econlib
Irving Fisher was one of America’s greatest mathematical economists and one of the clearest economics writers of all time. He had the intellect to use mathematics in virtually all his theories and the good sense to introduce it only after he had clearly explained the central principles in words. And he explained very well. […]| Econlib
The price of a share of stock, like that of any other financial asset, equals the present value of the sum of the expected dividends or other cash payments to the shareholders, where future payments are discounted by the interest rate and risks involved. Most of the cash payments to stockholders arise from dividends, which […]| Econlib
Bond markets are important components of capital markets. Bonds are fixed-income financial assets—essentially IOUs that promise the holder a specified set of payments. The value of a bond, like the value of any other asset, is the present value of the income stream one expects to receive from holding the bond. This has several implications: […]| Econlib
A worldwide depression struck countries with market economies at the end of the 1920s. Although the Great Depression was relatively mild in some countries, it was severe in others, particularly in the United States, where, at its nadir in 1933, 25 percent of all workers and 37 percent of all nonfarm workers were completely out […]| 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
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
The average U.S. consumer now enjoys a larger and higher-quality home than ever before. In 2001, the average home was 1,693 square feet, while in 1960 it was less than 1,200 square feet. In 2001, 58 percent of homes had three or more bedrooms, and 57 percent had 1.5 or more bathrooms. Compare that with […]| 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
