Called “the most prodigious classical liberal scholar of the 20th century,” Milton Friedman explained his importance:

• “Over the years, I have again and again asked fellow believers in a free society how they managed to escape the contagion of their collectivist intellectual environment. No name has been mentioned more often as the source of enlightenment than Friedrich Hayek’s.” (source)

Fifty years ago, Friedrich Hayek won the Nobel Prize in economics. However, the road that got him there was filled with skepticism and unheard warnings. Why were they ignored, and what makes them especially relevant today? Rediscover the ideas of F. A. Hayek and the historical context in which they were developed in this Libertarianism.org documentary.

Partial excerpt from my post about the sticker on the back of of my van: “Some of the Economists Pictured On My Van”

F.A. Hayek

(More at Econ Library) 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 years after they were written. Many graduate economics students today, for example, study his articles from the 1930s and 1940s on economics and knowledge, deriving insights that some of their elders in the economics profession still do not totally understand. It would not be surprising if a substantial minority of economists still read and learn from his articles in the year 2050. In his book Commanding Heights, Daniel Yergin called Hayek the “preeminent” economist of the last half of the twentieth century.

Hayek was the best-known advocate of what is now called Austrian economics. He was, in fact, the only major recent member of the Austrian school who was actually born and raised in Austria. After World War I, Hayek earned his doctorates in law and political science at the University of Vienna. Afterward he, together with other young economists Gottfried Haberler, Fritz Machlup, and Oskar Morgenstern, joined Ludwig von Mises’s private seminar—the Austrian equivalent of John Maynard Keynes’s “Cambridge Circus.” In 1927 Hayek became the director of the newly formed Austrian Institute for Business Cycle Research. In the early 1930s, at the invitation of Lionel Robbins, he moved to the faculty of the London School of Economics, where he stayed for eighteen years. He became a British citizen in 1938.

Most of Hayek’s work from the 1920s through the 1930s was in the Austrian theory of business cycles, capital theory, and monetary theory. Hayek saw a connection among all three. The major problem for any economy, he argued, is how people’s actions are coordinated. He noticed, as Adam Smith had, that the price system—free markets—did a remarkable job of coordinating people’s actions, even though that coordination was not part of anyone’s intent. The market, said Hayek, was a spontaneous order. By spontaneous Hayek meant unplanned—the market was not designed by anyone but evolved slowly as the result of human actions. But the market does not work perfectly. What causes the market, asked Hayek, to fail to coordinate people’s plans, so that at times large numbers of people are unemployed?

One cause, he said, was increases in the money supply by the central bank. Such increases, he argued in Prices and Production, would drive down interest rates, making credit artificially cheap. Businessmen would then make capital investments that they would not have made had they understood that they were getting a distorted price signal from the credit market. But capital investments are not homogeneous. Long-term investments are more sensitive to interest rates than short-term ones, just as long-term bonds are more interest-sensitive than treasury bills. Therefore, he concluded, artificially low interest rates not only cause investment to be artificially high, but also cause “malinvestment”—too much investment in long-term projects relative to short-term ones, and the boom turns into a bust. Hayek saw the bust as a healthy and necessary readjustment. The way to avoid the busts, he argued, is to avoid the booms that cause them.

Hayek and Keynes were building their models of the world at the same time. They were familiar with each other’s views and battled over their differences. Most economists believe that Keynes’s General Theory of Employment, Interest and Money (1936) won the war. Hayek, until his dying day, never believed that, and neither do other members of the Austrian school. Hayek believed that Keynesian policies to combat unemployment would inevitably cause inflation, and that to keep unemployment low, the central bank would have to increase the money supply faster and faster, causing inflation to get higher and higher. Hayek’s thought, which he expressed as early as 1958, is now accepted by mainstream economists (see phillips curve).

In the late 1930s and early 1940s, Hayek turned to the debate about whether socialist planning could work. He argued that it could not. The reason socialist economists thought central planning could work, argued Hayek, was that they thought planners could take the given economic data and allocate resources accordingly. But Hayek pointed out that the data are not “given.” The data do not exist, and cannot exist, in any one mind or small number of minds. Rather, each individual has knowledge about particular resources and potential opportunities for using these resources that a central planner can never have. The virtue of the free market, argued Hayek, is that it gives the maximum latitude for people to use information that only they have. In short, the market process generates the data. Without markets, data are almost nonexistent.

Mainstream economists and even many socialist economists (see socialism) now accept Hayek’s argument. Columbia University economist Jeffrey Sachs noted: “If you ask an economist where’s a good place to invest, which industries are going to grow, where the specialization is going to occur, the track record is pretty miserable. Economists don’t collect the on-the-ground information businessmen do. Every time Poland asks, Well, what are we going to be able to produce? I say I don’t know.”

In 1944 Hayek also attacked socialism from a very different angle. From his vantage point in Austria, Hayek had observed Germany very closely in the 1920s and early 1930s. After he moved to Britain, he noticed that many British socialists were advocating some of the same policies for government control of people’s lives that he had seen advocated in Germany in the 1920s. He had also seen that the Nazis really were National Socialists; that is, they were nationalists and socialists. So Hayek wrote The Road to Serfdom to warn his fellow British citizens of the dangers of socialism. His basic argument was that government control of our economic lives amounts to totalitarianism. “Economic control is not merely control of a sector of human life which can be separated from the rest,” he wrote, “it is the control of the means for all our ends.”

To the surprise of some, John Maynard Keynes praised the book highly. On the book’s cover, Keynes is quoted as saying: “In my opinion it is a grand book…. Morally and philosophically I find myself in agreement with virtually the whole of it; and not only in agreement with it, but in deeply moved agreement.”

Although Hayek had intended The Road to Serfdom only for a British audience, it also sold well in the United States. Indeed, Reader’s Digest condensed it. With that book Hayek established himself as the world’s leading classical liberal; today he would be called a libertarian or market liberal. A few years later, along with Milton Friedman, George Stigler, and others, he formed the Mont Pelerin Society so that classical liberals could meet every two years and give each other moral support in what appeared to be a losing cause. …
