Immigration is once again a major component of demographic change in the United States. Since 1940, the number of legal immigrants increased at a rate of one million per decade. By 2002, approximately one million legal immigrants were being admitted each year, a rate of almost ten million for the decade (Table 1). Large numbers […]| 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
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
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.

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

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
The marginal tax rate is the rate on the last dollar of income earned. This is very different from the average tax rate, which is the total tax paid as a percentage of total income earned. In 2003, for example, the United States imposed a 35 percent tax on every dollar of taxable income above […]| Econlib
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
Corporations are easier to create than to understand. Because corporations arose as an alternative to partnerships, they can best be understood by comparing these competing organizational structures. The presumption of partnership is that the investors will directly manage their own money rather than entrusting that task to others. Partners are “mutual agents,” meaning that each […]| 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.

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
“Law and economics,” also known as the economic analysis of law, differs from other forms of legal analysis in two main ways. First, the theoretical analysis focuses on efficiency. In simple terms, a legal situation is said to be efficient if a right is given to the party who would be willing to pay the […]| 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
Alfred Marshall was the dominant figure in British economics (itself dominant in world economics) from about 1890 until his death in 1924. His specialty was microeconomics—the study of individual markets and industries, as opposed to the study of the whole economy. In his most important book, Principles of Economics, Marshall emphasized that the price […]| Econlib
Irving Fisher was one of America’s greatest mathematical economists and one of the clearest economics writers of all time.

To most people, capital means a bank account, a hundred shares of IBM stock, assembly lines, or steel plants in the Chicago area.

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 private pension plan is an organized program to provide retirement income for a firm’s workers. Some 56.7 percent of full-time, full-year wage and salary workers in the United States participate in employment-based pension plans (EBRI Issue Brief, October 2003). Private trusteed pension plans receive special tax treatment and are subject to eligibility, coverage, and […]| Econlib
Telecommunications matters economically for two reasons.

Second, the […]| Econlib
A worldwide depression struck countries with market economies at the end of the 1920s.

“ Innovation”: creativity; novelty; the process of devising a new idea or thing, or improving an existing idea or thing.

More than any other economist, Paul Samuelson raised the level of mathematical analysis in the profession.

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.

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.

The concept of unintended consequences is one […]| Econlib
