Eugen von Böhm-Bawerk

By Nadia El-Masri

Eugen von Böhm-Bawerk was the rare theorist who also ran a treasury — three times Austria's finance minister — and the rarer still who used pure theory to demolish Marx. Born in Brünn, Moravia, in 1851, educated in law at Vienna, he was Menger's most brilliant student and the Austrian School's great systematizer. His life's work was Capital and Interest, published in two great installments: History and Critique of Interest Theories (1884), a devastating survey that takes apart every previous explanation of interest — including, in a famous final section, Marx's — and The Positive Theory of Capital (1889), which builds the Austrian account. The core is disarmingly simple. Interest exists because of time preference: a good available today is worth more than the same good available tomorrow, because human beings prefer present satisfactions to future ones, other things equal. Capitalist production is roundabout: instead of catching fish with bare hands, men build boats and nets first — longer, more indirect methods that are more productive precisely because they take time. Interest is the price of time, the discount on the future. From this Böhm-Bawerk derived a complete theory of capital, wages, and the structure of production — and turned it, in Karl Marx and the Close of His System (1896), into the most formidable internal critique Marxism ever faced: Marx's value theory, he argued, contradicts itself, since the third volume of Capital abandons labor values for prices of production whenever the argument requires it, and the exploitation theory collapses once time preference explains why present wages trade at a discount to future output. The Marxists answered for a century; the argument never quite died. As finance minister (1895, 1897–98, 1900–04), he practiced what he preached: balanced budgets, the gold standard, fiscal orthodoxy in an empire sliding toward war. He returned to teaching at Vienna in 1904, where his seminar trained Mises and Schumpeter — the two men who would carry his capital theory, in opposite directions, into the twentieth century's great debates. He died in 1914, weeks after the guns of August. His theory of interest — that it is not exploitation but the universal consequence of valuing the present over the future — remains the Austrian answer to every theory that treats profit as theft, and his analysis of roundabout production became the foundation of the Austrian theory of the business cycle. His 1904 seminar at Vienna, attended by the young Schumpeter and Mises together, remains legendary as the crucible in which twentieth-century Austrian economics was forged.

Impact on civilization

Böhm-Bawerk's impact is twofold: he gave the Austrian School its theory of capital, and he gave anti-Marxism its sharpest theoretical weapon. Time preference became a permanent part of economics — every modern theory of interest, from Fisher to the Ramsey model, descends from or through his formulation. His analysis of roundabout, time-consuming production methods underlies the Austrian business cycle theory developed by Mises and Hayek, which shaped the twentieth century's debates over central banking and credit. His critique of Marx — that the labor theory of value contradicts itself and that interest is not exploitation — set the terms of the socialist calculation debate and remains the standard liberal reply to exploitation theory. As a practitioner, his fiscal orthodoxy made him the model of the economist-statesman. He is the hinge between Menger and the twentieth-century Austrians: without Böhm-Bawerk, no Mises, no Hayek, no Austrian business cycle theory. Modern finance's term structure of interest rates is, in essence, Böhm-Bawerk's time-preference logic expressed in the language of markets.
