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
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
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
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
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
Although labor unions have been celebrated in folk songs and stories as fearless champions of the downtrodden working man, this is not how economists see them. Economists who study unions—including some who are avowedly prounion—analyze them as cartels that raise wages above competitive levels by restricting the supply of labor to various firms and industries.

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
Consumers pay a higher price for brand-name products than for products that do not carry an established brand name. Because this involves paying extra for what some consider an identical product that merely has been advertised and promoted, brand names may appear to be economically wasteful. This argument was behind the decision to eliminate all […]| Econlib
In 1974 the general public got a graphic illustration of the “tragedy of the commons” in satellite photos of the earth. Pictures of northern Africa showed an irregular dark patch 390 square miles in area. Ground-level investigation revealed a fenced area inside of which there was plenty of grass. Outside, the ground cover had been […]| Econlib
The fact that trade protection hurts the economy of the country that imposes it is one of the oldest but still most startling insights economics has to offer. The idea dates back to the origin of economic science itself. Adam Smith’s The Wealth of Nations, which gave birth to economics, already contained the argument for […]| 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
K-12 In the 1980s, economists puzzled by a decline in the growth of U.S. productivity realized that American schools had taken a dramatic turn for the worse. After rising every year for fifty years, student scores on a variety of achievement tests dropped sharply in 1967. They continued to decline through 1980. The decline was […]| Econlib
New Keynesian economics is the school of thought in modern macroeconomics that evolved from the ideas of John Maynard Keynes. Keynes wrote The General Theory of Employment, Interest, and Money in the 1930s, and his influence among academics and policymakers increased through the 1960s. In the 1970s, however, new classical economists such as Robert Lucas, […]| Econlib
Positive externalities are benefits that are infeasible to charge to provide; negative externalities are costs that are infeasible to charge to not provide. Ordinarily, as Adam Smith explained, selfishness leads markets to produce whatever people want; to get rich, you have to sell what the public is eager to buy. Externalities undermine the social benefits […]| 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
Is Health Care Different? Health care is different from other goods and services: the health care product is ill-defined, the outcome of care is uncertain, large segments of the industry are dominated by nonprofit providers, and payments are made by third parties such as the government and private insurers. Many of these factors are present […]| 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?

Telecommunications matters economically for two reasons. First, it plays a role perhaps second only to brain power in the operation and rapidly expanding productivity of the modern “information-based” economy; indeed, it supplies a primary technical means for productively harnessing the information and knowledge spread among individual economic actors throughout the global economic order. Second, the […]| Econlib
Until the so-called Keynesian revolution of the late 1930s and 1940s, the two main parts of economic theory were typically labeled “monetary theory” and “price theory.” Today, the corresponding dichotomy is between “macroeconomics” and “microeconomics.” The motivating force for the change came from the macro side, with modern macroeconomics being far more explicit than old-fashioned […]| 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
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.

Socialism—defined as a centrally planned economy in which the government controls all means of production—was the tragic failure of the twentieth century. Born of a commitment to remedy the economic and moral defects of capitalism, it has far surpassed capitalism in both economic malfunction and moral cruelty. Yet the idea and the ideal of socialism […]| Econlib
For more than two centuries economists have steadfastly promoted free trade among nations as the best trade policy. Despite this intellectual barrage, many “practical” men and women continue to view the case for free trade skeptically, as an abstract argument made by ivory tower economists with, at most, one foot on terra firma. These practical […]| Econlib

New York State legislators defend the War Emergency Tenant Protection Act—also known as rent control—as a way of protecting tenants from war-related housing shortages.

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
Economists approach the analysis of crime with one simple assumption—that criminals are rational.

Insurance plays a central role in the functioning of modern economies.

“ Free market” is a summary term for an array of exchanges that take place in society.

Economic competition takes place in markets—meeting grounds of intending suppliers and buyers.1 Typically, a few sellers compete to attract favorable offers from prospective buyers. Similarly, intending buyers compete to obtain good offers from suppliers. When a contract is concluded, the buyer and seller exchange property rights in a good, service, or asset. Everyone interacts voluntarily, […]| Econlib

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