“There are two kinds of people in the world: Johnny von Neumann and the rest of us.” This quote is attributed to Eugene Wigner, a Nobel Prize–winning physicist. John von Neumann, whom people called Johnny, was a brilliant mathematician and physicist who also made three fundamental contributions to economics. The first is a 1928 paper written in German that established von Neumann as the father of game theory. The second is a 1937 paper, translated in 1945, that laid out a mathematical model of an expanding economy and raised the level of mathematical sophistication in economics considerably. The third is a book coauthored with his Princeton colleague, economist Oskar Morgenstern, titled Theory of Games and Economic Behavior, after Morgenstern convinced von Neumann that game theory could be applied to economics. In their book, von Neumann and Morgenstern asserted that any economic situation could be defined as the outcome of a game between two or more players. But the semicompetitive/semicooperative nature of most economic situations, in which the value of the outputs is greater than the value of the inputs, increased the complexity, and consequently, the two were unable to offer solutions. “Nash equilibrium” solutions have since been found, addressing the skepticism some economists had expressed about the applicability of game theory to economics. In addition to game theory, the book gave birth to modern utility theory. Together, von Neumann and Morgenstern revived and mathematically structured the idea that individuals appear to be choosing among alternatives with probabilistic outcomes to maximize the expected amount of some measure of value termed “utility.” This clarified Knight’s concept of risk. The definition of utility they created led to the first coherent theory suggesting how we should make decisions when we know only the probabilities of some events.     The theory of games had been studied before, but after von Neumann and Morgenstern it received far more attention. Partly because of the enormous interest generated by their book, game theory has since been applied to economics, law, political science, and sociology. Von Neumann was born in Hungary and published his first mathematical paper at age eighteen. He earned a degree in chemical engineering in Zurich and a doctorate in mathematics from the University of Budapest in 1926. In 1933 he joined the Institute for Advanced Study at Princeton. He was the youngest permanent professor of that institution and a colleague of Albert Einstein. In 1943 von Neumann was a consultant to the Manhattan Project at Los Alamos, New Mexico, where the first atomic bomb was built. His work on the bomb led to a presidential appointment to the Atomic Energy Commission in 1955. Von Neumann also helped develop the first electronic computer, the ENIAC, at the University of Pennsylvania. Selected Works   1944 (with Oskar Morgenstern). Theory of Games and Economic Behavior.

Oskar Morgenstern is best known for his book, coauthored with physicist John von Neumann, Theory of Games and Economic Behavior. Morgenstern is also known for his skepticism about economic measurement. In a 1950 book, On the Accuracy of Economic Observations, Morgenstern challenged the easy use of data on national income to reach conclusions about the state of the economy and about appropriate policies, citing simon kuznets’s finding that the measurement of national income is subject to a 10 percent margin of error. Morgenstern pointed out that economic policy advisers often proposed policies based on shifts in national income of 1 percent or less. Morgenstern reasoned that one cannot reach any conclusions based on small shifts that are well within the margin of error. Morgenstern was born in Germany. After earning his doctorate, he became a professor at the University of Vienna in 1935. He was on leave in the United States in 1938 when the Nazis occupied Vienna. Dismissed from the university because he was considered “politically unbearable,” Morgenstern became a professor at Princeton University, where he remained until his retirement in 1970.

  François Quesnay was the leading figure of the Physiocrats, generally considered to be the first school of economic thinking. The name “Physiocrat” derives from the Greek words phýsis, meaning “nature,” and kràtos, meaning “power.” The Physiocrats believed that an economy’s power derived from its agricultural sector. They wanted the government of Louis XV, who ruled France from 1715 to 1774, to deregulate and reduce taxes on French agriculture so that poor France could emulate wealthier Britain, which had a relatively laissez-faire policy. Indeed, it was Quesnay who coined the term “laissez-faire, laissez-passer.” Quesnay himself did not publish until the age of sixty. His first work appeared only as encyclopedia articles in 1756 and 1757. In his Tableau économique, he detailed his famous zigzag diagram, a circular flow diagram of the economy that showed who produced what and who spent what, in an attempt to understand and explain the causes of growth. Tableau defined three classes: landowners, farmers, and others—called “sterile” classes—who consumed everything they produced and left no surplus for the next period. Quesnay believed that only the agricultural sector could produce a surplus that could then be used to produce more the next year—and therefore help growth. Industry and manufacturing, thought Quesnay, were sterile. Interestingly, though, he did not reach this conclusion by consulting his table. Instead, Quesnay constructed the table to fit his belief. Indeed, he had to make his table inconsistent in order to fit his assumption that industry provided no surplus. Although Quesnay was wrong about the sterility of the manufacturing sector, he was right in ascribing France’s poverty to mercantilism, which he called Colbertisme (after Louis XV’s finance minister, Jean-Baptiste Colbert). The French government had protected French manufacturers from foreign competition, thus raising the cost of machinery for farmers, and had also sold to wealthy citizens the power to tax farmers. These citizens had then used this power to the limit. Quesnay advocated reforming these laws by consolidating and reducing taxes, getting rid of tolls and other regulations that prevented trade within France, and generally freeing the economy from the government’s stifling controls. These reforms were much more sensible than his theorizing about the sterility of industry. As Mark Blaug writes, “It was only the effort to provide these reforms with a watertight theoretical argument that produced some of the forced reasoning and slightly absurd conclusions that invited ridicule even from contemporaries.”1 Moreover, Quesnay’s work paved the way for classical economics—in particular for Adam Smith, who latched on to Physiocratic notions of free trade and the preeminence of the agricultural sector. That Quesnay had such a seminal influence on economics is all the more surprising in light of the fact that he served under Louis XV in Versailles not as an economist, but as a medical doctor.

  Ludwig von Mises was one of the last members of the original austrian school of economics. He earned his doctorate in law and economics from the University of Vienna in 1906. One of his best works, The Theory of Money and Credit, was published in 1912 and was used as a money and banking textbook for the next two decades. In it Mises extended Austrian marginal utility theory to money, which, noted Mises, is demanded for its usefulness in purchasing other goods rather than for its own sake. In that same book Mises also argued that business cycles are caused by the uncontrolled expansion of bank credit. In 1926 Mises founded the Austrian Institute for Business Cycle Research. His most influential student, Friedrich Hayek, later developed Mises’s business cycle theories. Another of Mises’s notable contributions is his claim that socialism must fail economically. In a 1920 article, Mises argued that a socialist government could not make the economic calculations required to organize a complex economy efficiently. Although socialist economists Oskar Lange and Abba Lerner disagreed with him, modern economists agree that Mises’s argument, combined with Hayek’s elaboration of it, is correct (see socialism). Mises believed that economic truths are derived from self-evident axioms and cannot be empirically tested. He laid out his view in his magnum opus, Human Action, and in other publications, although he failed to persuade many economists outside the Austrian school. Mises was also a strong proponent of laissez-faire; he advocated that the government not intervene anywhere in the economy. Interestingly, though, even Mises made some striking exceptions to this view. For example, he believed that military conscription could be justified in wartime. From 1913 to 1934 Mises was an unpaid professor at the University of Vienna while working as an economist for the Vienna Chamber of Commerce, in which capacity he served as the principal economic adviser to the Austrian government. To avoid the Nazi influence in his Austrian homeland, in 1934 Mises left for Geneva, where he was a professor at the Graduate Institute of International Studies until he emigrated to New York City in 1940. He was a visiting professor at New York University from 1945 until he retired in 1969. Mises’s ideas—on economic reasoning and on economic policy—were out of fashion during the Keynesian revolution that took over American economic thinking from the mid-1930s to the 1960s. Mises’s upset at the Keynesian revolution and at Hitler’s earlier destruction of his homeland made Mises bitter from the late 1940s on. The contrast between his early view of himself as a mainstream member of his profession and his later view of himself as an outcast shows up starkly in The Theory of Money and Credit. The first section, written in 1912, is calmly argued; the last section, added in the 1940s, is strident. Mises had a strong influence on young people. The resurgent Austrian school in the United States owes itself in no small part to Mises’s persistence. Selected Works   1912. The Theory of Money and Credit. 3d English ed.

  In 1996 James Mirrlees and william vickrey were awarded the Nobel Prize in economics “for their fundamental contributions to the economic theory of incentives under asymmetric information.” Mirrlees’s main contribution was some highly complex mathematics that allowed him to solve a problem in taxation that William Vickrey had posed but had not been able to answer. Many economists, including Mirrlees, want to use the tax system to achieve a higher degree of equality than would otherwise obtain. This means taking a substantial amount of the additional income of high-income people, which would imply high marginal tax rates on them. But when the government imposes such high marginal tax rates on the highest-income people, it reduces the incentive of the most productive people to be productive. There is, in short, a trade-off between equality and efficiency. Economists have long wanted to figure out the optimum, but until Mirrlees’s work no one had been able to solve it. Mirrlees started with no presumption against high marginal tax rates. Indeed, he has been an adviser to Britain’s Labour Party, which for decades imposed marginal tax rates in excess of 80 percent. But Mirrlees found that the top marginal tax rate should be only about 20 percent; and moreover, it should be about the same 20 percent for everyone. In short, Mirrlees’s work justified what is now known as a “flat tax,” more appropriately called a “flat tax rate.” Mirrlees wrote, “I must confess that I had expected the rigourous analysis of income taxation in the utilitarian manner to provide arguments for high tax rates. It has not done so.”1 Indeed. Mirrlees also proved that the marginal tax rate on the highest-income person should be zero. This is the opposite of the way most noneconomists and most politicians think: marginal tax rates are typically the highest on the highest-income people. Mirrlees’s reasoning is as follows. Imagine that the top tax rate is, say, 40 percent and that the top-earning person makes $500 million in a year before tax. If the government reduced the marginal tax rate to zero for all income over $500 million, it would not lose any revenue because no one was earning more than $500 million. But the individual currently earning $500 million might, because of the increased incentive to earn, decide to work more. He would be better off because he voluntarily chose to do something he did not do before, and the government would be no worse off. The net result is that society, which includes this individual, would be better off. Mirrlees’s work on consumption taxes produced another important finding. Working with American economist Peter Diamond, Mirrlees found that small economies should not impose tariffs on foreign trade and that taxation should be on consumption, not production. Mirrlees also did highly theoretical work on another incentive problem: “moral hazard.” As is well known to those who study insurance, insurance coverage gives the beneficiary an incentive to take more risks than would be optimal. This is called “moral hazard.” Mirrlees’s insight, based on a complex mathematical model, is that the problem can be solved with an optimal combination of carrots and sticks. Insurance payments are essentially a carrot. But “sticks” could be designed also, so that an insured person who takes risks pays a penalty for doing so. With this combination of carrots and sticks, the insured person acts almost as if he is uninsured, and the insurer acts almost as if he were the insured. Mirrlees has a refreshing, understated sense of humor. Of his early years in university Mirrlees wrote: “It was regarded as morally dangerous to take philosophy at the beginning of one’s university course.” Reminiscing in 1996 on the advice one of his Cambridge teachers gave him to read Keynes’s 1936 classic, The General Theory of Employment, Interest and Money, Mirrlees commented, “That may not have been the best advice, but it did no great harm, and one day I hope to finish it.” Born in Scotland, Mirrlees earned his M.A. in mathematics and natural philosophy from Edinburgh University in 1957 and his Ph.D. in economics from Cambridge University in 1963. He spent his early career at Cambridge, was an economics professor at the University of Oxford from 1968 to 1995, and returned to Cambridge in 1995 as an economics professor.

In 1979, British citizen W. Arthur Lewis was awarded the Nobel Prize, along with theodore schultz, for “pioneering research into economic development … with particular consideration of the problems of developing countries.” One of Lewis’s major contributions to economics is a 1954 article that discusses his concept of a “dual economy” in a poor country. According to Lewis a poor country’s economy can be thought of as containing two sectors, a small “capitalist” sector and a very large “traditional” (agricultural) sector. Employers in the capitalist sector hire people to make money. Employers in the traditional sector, on the other hand, are not profit maximizing and, therefore, hire too many people so that their productivity is very low. (The immediate question, of course, is why employers in the traditional sector would do this, and economists still debate Lewis’s reasons for thinking this.) Lewis argued on this basis that the way to spur development in poor countries is to shift labor into manufacturing, where it is more productive. The capitalists save out of their profits and use this saving to expand, which then adds to growth. Lewis assumed that workers in agriculture save nothing, so that the only source of saving is the capitalists in manufacturing. Lewis used his model to explain the pattern of growth in countries in general. This is how he explained the inverted-U-shaped growth according to a country’s per capita income. For very poor countries like Bangladesh, growth is slow because the manufacturing sector is small or nonexistent, and there is no large source of savings. For middle-income countries like Korea and Taiwan, growth is high because the manufacturing sector is growing and pulling labor out of agriculture, where it is underemployed. For high-income countries with a large manufacturing sector, like the United States, growth is slower because the gains from diverting labor out of agriculture are almost all exploited. In the same 1954 article Lewis made a separate argument for poor countries engaged in trade, maintaining that poor countries would capture little or no benefit from increasing their exports. Instead, he claimed, they would confer benefits on consumers in the countries that import their exports. Take his example in which the richer countries produce steel (shorthand for manufactured goods) and food, and the poorer countries produce coffee (shorthand for exports of poor countries) and food. Assume that before exports are increased, ten pounds of coffee trade for one ton of steel. Now, because producers in the poor countries have a low opportunity cost of increasing exports of coffee (because the food that they could have produced is worth little), they will increase exports. But doing so will drive down the price of coffee. Say the exchange rate falls to twenty pounds of coffee per ton of steel. This is a good deal for coffee buyers, but not for coffee producers. In essence, Lewis was arguing that poorer countries had latent monopoly power in their exports that they were failing to exploit. These countries would do better, he argued, to divert their production into food and away from exports. Lewis himself came from a poor British colony, Saint Lucia in the West Indies. He entered the London School of Economics on a scholarship at age eighteen. “I wanted to be an engineer,” Lewis later said, “but neither the colonial government nor the sugar plantations would hire a black engineer.” So he decided to study economics. He earned his Ph.D. from the London School of Economics in 1940. He began working on problems of the world economy at the suggestion of friedrich hayek, then chairman of the LSE’s economics department. After World War II, when many former colonies became independent, Lewis began his study of economic development. Lewis had no sympathy for the view that poor countries should be run by dictators so that they could develop. Lewis was a lecturer at the University of London from 1938 to 1948, then Stanley Jevons Professor of Political Economy at the University of Manchester from 1948 to 1958. He was vice chancellor of the University of West Indies from 1959 to 1963 and a professor of political economy at Princeton University from 1963 until his death. Selected Works   1949.

  Simon Kuznets is best known for his studies of national income and its components. Prior to World War I, measures of GNP were rough guesses, at best. No government agency collected data to compute GNP, and no private economic researcher did so systematically, either. Kuznets changed all that. With work that began in the 1930s and stretched over decades, Kuznets computed national income back to 1869. He broke it down by industry, by final product, and by use. He also measured the distribution of income between rich and poor. Although Kuznets was not the first economist to try this, his work was so comprehensive and meticulous that it set the standard in the field. His work was funded by the nonprofit National Bureau of Economic Research, which had been started in 1920. Kuznets later helped the U.S. Department of Commerce to standardize the measurement of GNP. In the late 1940s, however, he broke with the Commerce Department over its refusal to use GNP as a measure of economic well-being. He had wanted the department to measure the value of unpaid housework because this is an important component of production. The department refused, and still does. Kuznets’s development of measures of savings, consumption, and investment came along just as Keynes’s ideas about how national income is determined created a demand for such measures. Thus, Kuznets helped advance the Keynesian revolution. Kuznets’s measures also helped advance the study of econometrics established by ragnar frisch and jan tinbergen. Kuznets approached his work with a strict adherence to fact and a desire to understand economic phenomena through quantitative measurement. He had started early in his native Russia: he was head of a statistical office in the Ukraine under the Bolsheviks before moving to the United States at age twenty-one. Many economists believe that Kuznets received the 1971 Nobel Prize for his measurement in national income accounting, and certainly that was enough to merit the prize. But in fact, the prize was awarded for his empirical work on economic growth. In this work Kuznets identified a new economic era—which he called “modern economic growth”—that began in northwestern Europe in the last half of the eighteenth century. The growth spread south and east and by the end of the nineteenth century had reached Russia and Japan. In this era, per capita income rose by about 15 percent or more each decade, something that had not happened in earlier centuries. One of Kuznets’s more startling findings concerns the effect of economic growth on income distribution. In poor countries, he found, economic growth increased the income disparity between rich and poor people. In wealthier countries, economic growth narrowed the difference. In addition, Kuznets analyzed and quantified the cyclical nature of production and prices in spans of fifteen to twenty years. Such trade cycles, while disputed, are often referred to as “Kuznets cycles.” Kuznets was a professor of economics at the University of Pennsylvania (1930–1954), Johns Hopkins University (1954–1960), and Harvard University (1960–1971).

Tjalling Koopmans shared the 1975 Nobel Prize with Leonid Kantorovich “for their contributions to the theory of optimum allocation of resources.” Koopmans, a native of the Netherlands, started in mathematics and physics, but in the 1930s switched to economics because it was “closer to real life.” In 1938 he succeeded Jan Tinbergen at the League of Nations in Geneva and then left in 1940 when Hitler invaded the Netherlands. In the United States, Koopmans became a statistician with the Combined Shipping Adjustment Board in Washington where he tried to solve the practical problem of how to reorganize shipping to minimize transportation costs. The problem was complex: the variables included thousands of merchant ships, millions of tons of cargo, and hundreds of ports. He solved it. The technique he developed to do so was called “activity analysis” and is now called linear programming. His first write-up of the analysis is in a 1942 memorandum. His techniques were very similar to those used by Kantorovich, whose work he discovered only much later. Koopmans was also like Kantorovich in generalizing his approach from one sector of the economy to the economy as a whole. Koopmans showed the conditions required for economy-wide efficiency in allocating resources. He also, again like Kantorovich, used his activity analysis techniques to derive efficient criteria for allocating between the present and the future. Koopmans was an economist with the Cowles Commission at the University of Chicago between 1944 and 1955, and then moved with the Cowles Commission to Yale University, where he became a professor of economics until he retired in 1981. Koopmans became an American citizen in 1946. He served as president of the American Economic Association in 1981.

  Carl Menger has the twin distinctions of being the founder of Austrian economics and a cofounder of the marginal utility revolution. Menger worked separately from William Jevons and Leon Walras and reached similar conclusions by a different method. Unlike Jevons, Menger did not believe that goods provide “utils,” or units of utility. Rather, he wrote, goods are valuable because they serve various uses whose importance differs. For example, the first pails of water are used to satisfy the most important uses, and successive pails are used for less and less important purposes. Menger used this insight to resolve the diamond-water paradox that had baffled Adam Smith (see marginalism). He also used it to refute the labor theory of value. Goods acquire their value, he showed, not because of the amount of labor used in producing them, but because of their ability to satisfy people’s wants. Indeed, Menger turned the labor theory of value on its head. If the value of goods is determined by the importance of the wants they satisfy, then the value of labor and other inputs of production (he called them “goods of a higher order”) derive from their ability to produce these goods. Mainstream economists still accept this theory, which they call the theory of “derived demand.” Menger used his “subjective theory of value” to arrive at one of the most powerful insights in economics: both sides gain from exchange. People will exchange something they value less for something they value more. Because both trading partners do this, both gain. This insight led him to see that middlemen are highly productive: they facilitate transactions that benefit those they buy from and those they sell to. Without the middlemen, these transactions either would not have taken place or would have been more costly. Although Adam Smith beat him to it in The Wealth of Nations (Book I, Chapter IV), Menger came up with an explanation of how money develops that is still accepted today. If people barter, he pointed out, then they can rarely get what they want in one or two transactions. If they have lamps and want chairs, for example, they will not necessarily be able to trade lamps for chairs but may instead have to make a few intermediate trades. This is a hassle. But people notice that the hassle is much less when they trade what they have for some good that is widely accepted, and then use this good to buy what they want. The good that is widely accepted eventually becomes money. Modern economists describe this function of money as “avoiding the need for the double coincidence of wants.” Indeed, the word “pecuniary” derives from the Latin pecus, meaning “cattle,” which in some societies served as money. Other societies have used cigarettes, cognac, salt, furs, or stones as money. As economies became more complex and wealthier, they began to use precious metals (gold, silver, and so on) as money. Menger extended his analysis to other institutions. He argued that language, for example, developed for the same reason money developed—to facilitate interactions between people. He called such developments “organic.” Neither language nor money was developed by government. The austrian school of economic thought first coalesced from Menger’s writings and those of two young disciples, Eugen von Böhm-Bawerk and Friedrich von Wieser. Later Austrian economists Ludwig von Mises and Friedrich Hayek used Menger’s insights as a starting point, Mises with his work on money and Hayek with his idea of “spontaneous order.” Carl Menger was born in Galicia, part of Austro-Hungary (now southern Poland), to a prosperous family. He had two brothers, Anton and Max. Both brothers were lawyers, and Anton was a legal philosopher and socialist historian. Menger’s son, Karl Menger, was a prominent mathematician who spent most of his professional life in the United States and died in 1985. Carl earned his doctorate in law from the University of Kraków in 1867. As a result of publishing his Principles of Economics in 1871, he was given a lectureship and then a professorship at the University of Vienna, which he held until 1903. In 1876 he took a post as tutor for Crown Prince Rudolf of Austria. In that capacity he traveled throughout Germany, France, Switzerland, and England. Selected Works Further Reading   1871.

  James Meade, an Englishman, was corecipient of the Nobel Prize in 1977, along with Bertil Ohlin, for their “pathbreaking contribution to the theory of international trade and international capital movements.” Much of Meade’s work on international trade is in the two volumes of his Theory of International Economic Policy, which, writes Mark Blaug, “have become the bible of every trade economist.” The book’s first volume, The Balance of Payments, makes the point that for each of its policy objectives, the government requires a policy tool, a principle developed by Dutch economist Jan Tinbergen. Meade advocated using fiscal policy to achieve full employment and monetary policy to achieve the government’s target on balance of payments. The second volume, Trade and Welfare, examines conditions under which free trade makes a country better off and conditions under which it does not. Meade concluded that, contrary to previous beliefs, if a country was already protecting one of its markets from international competition, further protection of another market could be “second best.” That is, although the ideal would be to eliminate all trade barriers, if for some reason this was not feasible, then adding a carefully chosen dose of protectionism could improve the nation’s economic well-being. Like Milton Friedman in the United States, Meade wanted to use economics to help make the world a better place and believed that government regulation often harmed an economy. He also believed that government should take strong measures to promote equality of income. “I have my heart to the left and my brain to the right,” Meade said. Meade also helped prepare the British government’s set of national income accounts during World War II. Meade was a professor of commerce at the London School of Economics from 1947 to 1957 and then moved to Cambridge University, where he taught until he retired in 1974. Selected Works   1951.
