Remembering Oskar Morgenstern

By Richard M. Ebeling

This week we commemorate Austrian-born economist Oskar Morgenstern’s birthday. Born on January 24, 1902, he died on July 26, 1977, at the age of 75. He is best known as the co-developer of modern game theory with John von Neumann in their 1944 book, “The Theory of Games and Economic Behavior,”
Morgenstern had been educated at the University of Vienna, studying with one of the early leaders of the Austrian School of Economics, Friedrich von Wieser. But his main “Austrian” mentor was Hans Mayer, who replaced Wieser at the time of the latter’s retirement in 1923. (Hans Mayer was the author in 1932 of a 100-page monograph offering an “Austrian” critique of mathematical general equilibrium theory.)
Morgenstern’s first book was on “Economic Forecasting” (1928), in which he argued that precise predictions in the realm of economics was inherently impossible due to the unique qualities of the social sciences arising from human beings as intentional, thinking men whose very expectations about the future can frustrate the projections the forecaster attempts to make about their anticipated conduct. In addition, the events in the human arena have sufficiently distinct and unique characteristics that many of the assumptions underlying probability theory could not be easily applied to economic and market processes.
His 1934 book on, “The Limits of Economic Policy,” was meant to bring out the difficulties inherent in policy making because of the complexity in the interactive events of the market, which are wrapped up in time and causal sequences that hampers what the economic policy maker could successfully manage and control. He also warned of those who approach policy issues with predetermined ideological biases that could influence the logic of the policy-maker’s analyses and conclusions.
Shortly after the founding of the Austrian Institute for Business Cycle Research in 1928 under the directorship of a young Friedrich A. Hayek, Morgenstern was hired as his assistant. Morgenstern replaced Hayek as the Institute’s director when Hayek accepted an appointment at the London School of Economics in the autumn 1931. He held this position until March 1938. Morgenstern was on a lecture tour in the United States when Austria was invaded and annexed by Nazi Germany. Exiled in America, he ended up with a position at Princeton University, until he retirement at which point he took up a professorship at New York University.
It was in this capacity at NYU that I came to know Morgenstern. Indeed, I (and Don Lavoie and Jack High) took Morgenstern for his last class at NYU on the History of Economic Thought before his death from cancer.
I found him to be a most approachable and friendly person, who happily spent time with me with my questions about the “old Vienna days” in the years between the wars and his interactions with the other members of the Austrian School.
A few years ago, I wrote a review of Robert Leonard’s excellent book, “Von Neumann, Morgenstern and the Creation of Game Theory.”
The book presented a different side of Morgenstern, based on Leonard’s researches, including the entries in Morgenstern’s private diary. We find someone partly envious and resentful of other members of the Austrian School in that interwar period of the 1920s and 1930s, and willing to collaborate with the fascist-type government that ruled Austria before the annexation of the country in March 1938 by the Nazis. And he was certainly very much the “junior partner” in the development of game theory, often finding it hard to keep up with von Neumann’s mathematical formulations and demonstrations.
One aspect of his “Austrian” roots that Morgenstern retained was his healthy suspicions about the limits of macroeconomic aggregates and averages as a meaningful approach for understanding the dynamics of money’s influence on the market process. Indeed, he always emphasized the need for microeconomic process analyses of money’s “non-neutrality” on the structure of relative prices and wages, profit margins, and resulting potential misallocations of capital and labor.
Thus, for instance in his 1972 article on, ‘Thirteen Critical Points in Contemporary Economic Theory,’ he insisted:
The concentration on undifferentiated aggregates as, say, that of the total quantity of money, is a step backward into a more primitive world of thought. It runs counter to what must be done . . .
Consider an inflationary, or as a matter of fact, any increase in the total quantity of money. If no account is given where this additional money originates from, where it is injected, with what different magnitudes and how it penetrates (through which paths and channels, and with what speed), into the body economic, very little information is given.
The same total addition will have very different consequences if it is injected via consumers’ loans, or via producers’ borrowing, via the Defense Department, or via unemployment subsidies, etc. Depending on the existing condition of the economy, each point of injection will produce different consequences for the same aggregate amount of money, so that the monetary analysis will have to be combined with an equally detailed analysis of changing flows of commodities and services.
