Ludwig von Mises

By Laura Whitfield

Ludwig von Mises spent half a century as the most uncompromising defender of the free market who ever lived, and he did it mostly from exile. Born in Lemberg, Galicia, in 1881, educated in law at Vienna, he joined the Austrian finance administration and then Böhm-Bawerk's seminar — the student who would carry the master's capital theory into the twentieth century's great battle. His first shot was money: The Theory of Money and Credit (1912) integrated money into marginal-utility theory and gave the Austrian account of the business cycle — bank credit expansion drives interest below its natural level, distorts the structure of production toward longer projects, and the bust is the inevitable correction. Then, in 1920, the article that made him famous and made him enemies for life: Economic Calculation in the Socialist Commonwealth. His argument was devastating in its simplicity. Rational economic allocation requires prices; prices require exchange; exchange requires private ownership of the means of production. Abolish private ownership and you abolish not only markets but the very possibility of knowing what anything costs — socialism, Mises argued, cannot calculate, and therefore cannot be rational, whatever its intentions. The socialist calculation debate that followed — with Hayek, Lange, Lerner, and generations of economists — became the twentieth century's great theoretical contest, and Mises's challenge was never conclusively answered, only circumvented by models that assumed away the problem. In Red Vienna he ran his famous private seminar, training Hayek, Haberler, Machlup, and Morgenstern while serving as the Austrian Chamber of Commerce's chief economist — the unsung power behind Austria's resistance to inflationary finance. The Nazis' arrival forced him out: Geneva in 1934, then New York in 1940, where at fifty-nine he rebuilt his life teaching at NYU, unpaid by the university, paid by admirers. There he wrote his summa, Human Action (1949): economics as praxeology, the deductive science of human action, beginning from the axiom that humans act purposefully and deriving the whole of economic law — prices, interest, money, cycles — without a single appeal to psychology or history. It is the most complete statement of the Austrian worldview ever written, and the most radical: all of economics, deduced from one self-evident truth. He died in New York in 1973, at ninety-one, just as the stagflation crisis was making the world receptive, at last, to everything he had said. The collapse of central planning in 1989–91 was read by his followers as the empirical vindication of the 1920 article: the calculation argument, tested at the scale of half the planet, had held.

Impact on civilization

Mises's impact is the intellectual case against central planning and the foundation of modern libertarian economics. The calculation argument reshaped the twentieth century's central economic debate: even socialist economists conceded that the problem was real, and the most sophisticated defenses of planning — Lange's market socialism — were constructed as answers to Mises. His business cycle theory, developed by Hayek, became the Austrian account of booms and busts and influenced a generation of central bank critics. Human Action founded praxeology as a research program and became the bible of the modern libertarian movement: Rothbard, Kirzner, and the entire apparatus of free-market think tanks descend from Mises's NYU seminar. His methodological individualism — economics as the logic of purposeful action — remains the Austrian School's permanent challenge to mathematical modeling. When the Soviet bloc collapsed unable to compute its own economy, the obituaries of planning were written, knowingly or not, in Mises's vocabulary.
