Economist Oskar Morgenstern is
best known as the co-developer, with mathematician John von Neumann, of game
theory. Game theory emerged out of curiosities about the logic and strategies
of games such as chess, where each player must take into consideration the
plans and possible moves of an opponent if he is to have any success in winning
the game. It culminated in the 1944 publication of Morgenstern and von
Neumann’s book, The Theory of Games and Economic Behavior.
It has been applied to the
planning of military strategy, as well as for attempting to design or
anticipate competitive moves by rivals in the marketplace. Its most famous
construction is what is called “the prisoner’s dilemma,” in which two suspected
criminals are offered, separately, a lower sentence if one of them confesses
and “rats out” the other first. Neither could be convicted if both of them kept
their mouth shut, but since neither one can be sure that the other won’t take
the deal, they both end up confessing.
It has also been used to
explain the logic of cooperative behavior in the marketplace of exchange. In
his 1984 book, The Evolution of Cooperation, for
example, Robert Axelrod, explained that when people participate in or
anticipate multiple trading opportunities with others, there emerge incentives
to neither cheat nor deceive. Game theory experiments showed that most people
implicitly operate in terms of a psychology of “tit-for tat.” That is, each
trader will be honest and reliable in his dealings as long as his trading
partner acts the same way. If “Sam” cheats or is in any way dishonest, then
“Bob” will “retaliate” in kind. But if “Sam” learns his lesson and starts
acting honestly again, then “Bob” will reciprocate, and mutually beneficial and
honest trade will be restored.
The logic is that when individuals realize that there are long-run gains from “repeat business” with the same trading partners, it becomes costly to try to obtain short-run gains by acting dishonestly against them. Thus, in the long run, market interactions reinforce and teach the value of honest behavior and good manners.
Robert Leonard’s book, Von Neumann, Morgenstern and the Creation of Game Theory,
is an outstanding example of scholarship, matched by an easy flowing writing
style that explains often difficult and complex mathematical and logical
problems that led up to the development of game theory. It is told in terms of
the separate biographies of Von Neumann and Morgenstern who, in fact, had
virtually no contact with each other until they were both at Princeton
University starting in the late 1930s.
But what I would like to focus
on in the remainder of this review is the evolution of Oskar Morgenstern’s
ideas in this process, because what is less well known is that Morgenstern was
a prominent member of the Austrian School of Economics before the Second World
War.
His first book was on Economic Forecasting (1928), which unfortunately
has never been translated into English. He presented a biting and insightful
analysis as to why quantitative models would never be able to successfully
predict the economic future. His three fundamental arguments were (1) that
historical events are too unique and interdependently complex to be reducible
to statistical probability analysis; (2) any public forecast easily will result
in people taking the forecast into consideration, and therefore acting in ways
different than what the forecast presumed; and (3) how individuals act is
dependent on their expectations of how they expect others to act, and
understanding and interpreting people’s subjective meanings and intentions is
not readily reducible to strictly quantitative categories and classifications
for statistical study.
Leonard traces out the
development of Morgenstern’s thinking in the 1920s and 1930a under the
influence of Austrian Economists such as Ludwig von Mises and Hans Mayer, and
his friendship with Karl Menger, Jr., the son of the founder of the Austrian
School.
But what he also brings out is
how Morgenstern increasingly turned against his “Austrian” roots, ridiculing in
print Mises’s views on economic theory and policy, and telling his various
economist friends that he considered F. A. Hayek’s work on money and business
cycles to be “worthless” – some of the very contributions that resulted in
Hayek being awarded the Nobel Prize in Economics in 1974!
Even worse, after 1934, with
Hayek now a professor at the London School of Economics, and Mises teaching in
Geneva, Switzerland, Morgenstern attempted to portray himself as the “leader”
of the Austrian School in an Austria that was now a fascist-type authoritarian
dictatorship. He worked as a senior advisor to the Austrian government, often
offering policy advice far removed from a free market perspective. And in his
1934 book, The Limits of Economic Policy, he expressed impatience
with democratic government compared to an authoritarian system. (When the book
appeared in English in 1937, he deleted its anti-democratic passages.)
In addition, Leonard points
out that Morgenstern’s diary from this period is sprinkled with often heavily
anti-Semitic sentiments, in spite of the fact that many of the members of the
Austrian School at this time were Jewish (including Mises), and who had been
among those encouraging and supportive of his own work and professional
advancement.
Finally, while during his
life-time Morgenstern was hailed as the co-developer of game theory, Leonard
makes it clear that in fact virtually all of its theoretical formulations and
strategy constructs in their 1944 book was the work of von Neumann (also of
Jewish ancestry). Morgenstern’s contribution was mostly a couple of chapters
showing the possible applications of game theory to economics. Leonard quotes
Morgenstern’s diary that he often could barely keep up with von Neumann’s
mathematical expositions.
I had the privilege of having
Oskar Morgenstern as a professor at New York University just before his death
in 1977. He was an excellent lecturer, and very generous with his time to share
his ideas and memories of the “old Vienna days,” with someone interested in the
history of the Austrian School.
This is what made Leonard’s
book so much of a shock. It shows an unflattering, dark side of a fascinating
man. A man who, at least during that earlier period between the two World Wars,
too frequently demonstrated envy, arrogance, and prejudice against some of the
very people who helped make his own professional success possible.
