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. Menger dedicated Principles of Economics to his German colleague William Roscher, the leading figure in the German historical school, which dominated economic […]| Econlib
Since the 1870s, economists have agreed that value is subjective, but, following Alfred Marshall, many argued that the cost side of the equation is determined by objective conditions. Marshall insisted that just as both blades of a scissors cut a piece of paper, so subjective value and objective costs determine price…But Marshall failed to appreciate […]| Econlib
This essay is part of an occasional series on fundamental economic concepts. “Prices adjust. They’re not fixed. Supply and demand helps us remember this.” My three sons, ages seven to twelve, suffer from a chronic condition I’ve heard described by economist John Baden as ironitis—the love of anything made of metal. They are fascinated by […]| Econlib
As this semester closed, I asked several colleagues who taught introductory economics courses to name the most difficult topics to teach to first-time economics students. There was some variation in their answers, but one concept was mentioned far more often than any other—elasticity. In this Teacher’s Corner, we will define what elasticity means in economics, […]| Econlib
Arthur C. Pigou, a British economist, is best known for his work in welfare economics. In his book The Economics of Welfare Pigou developed alfred marshall’s concept of externalities, costs imposed or benefits conferred on others that are not taken into account by the person taking the action. He argued that the existence of […]| Econlib
So influential was John Maynard Keynes in the middle third of the twentieth century that an entire school of modern thought bears his name. Many of his ideas were revolutionary; almost all were controversial. Keynesian economics serves as a sort of yardstick that can define virtually all economists who came after him. Keynes was […]| 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
In recent years, taxation has been one of the most prominent and controversial topics in economic policy. Taxation has been a principal issue in every presidential election since 1980—with a large tax cut as a winning issue in 1980, a pledge of “Read my lips: no new taxes” in the 1988 campaign, and a statement […]| Econlib
More than any other economist, Paul Samuelson raised the level of mathematical analysis in the profession. Until the late 1930s, when Samuelson started his stunning and steady stream of articles, economics was typically understood in terms of verbal explanations and diagrammatic models. Samuelson wrote his first published article, “A Note on the Measurement of […]| 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
The most basic laws in economics are the law of supply and the law of demand. Indeed, almost every economic event or phenomenon is the product of the interaction of these two laws. The law of supply states that the quantity of a good supplied (i.e., the amount owners or producers offer for sale) rises […]| Econlib
One of the most important building blocks of economic analysis is the concept of demand. When economists refer to demand, they usually have in mind not just a single quantity demanded, but a demand curve, which traces the quantity of a good or service that is demanded at successively different prices. The most famous law […]| Econlib
