Maurice Allais
was born in 1911 in Paris, France and later became a famous French economist
and physicist who primarily studied macroeconomic theory and policies and
helped pioneer the field. He was the first ever French citizen to receive the Nobel
Prize in Economic Sciences, which he received in 1988 for his contributions to
the theory of markets and efficient resource allocation. However, he did not
get as much credits as other economists because he was committed to publishing
his findings only in French rather than also publishing translations in
English. As a result, there is a belief that Allais’ impact on economic theory
would have been much more significant had his writings been in English. Nonetheless,
Allais’ earliest writings have contributed significantly to what is now
considered the generally accepted economic theory.
Apart from this, he is also known for his discoveries
in utility theory, specifically decision-making under risk, in which he discovered
a paradox about how people behave when choosing between various risks. This
paradox is now known as the Allais paradox. Using this paradox, Allais
was able to show that John von Neumann and Oscar Morgenstern’s widely accepted
theory of maximization of expected utility was contradicted based on
observations Allais’ had made about how humans behave when taking important
decisions with risk involved.
Many of Allais’ observations and discoveries
have been applied to the real world, for example Allais’ knowledge in the field
was applied to helping set efficient prices for France’s many state-owned
monopolies. Allais and his work have also been cited as a key source of
inspiration by several young French economists and this will most likely have an
immense impact on the field of economics in the coming decades. Allais has also
had a huge influence on market theory by trying to generalize it since there
are many dynamic aspects of the market in reality.
Allais’ work has been extremely significant in
developing the field theoretically and understanding the way the world and humans’
function practically. Additionally, his work has also contributed via the many
ways that his theories have been used in the real world. Apart from his considerable
contributions to economic theory, Allais’ has also done research and published
studies in relation to history and physics, specifically geophysics. For
example, Allais carried out research about the behaviour of pendulums (their
angular velocity) during a solar eclipse which yielded an unexpected anomalous
effect. This effect is now known as the Allais effect. While proceeding experiments
and research was carried out by several other scientists regarding this effect
and have yielded mixed results, this shows that Allais’ impact outside the field
of economic theory is still substantial.
Before taking this class, I did not know much
about Maurice Allais’ contribution to field of economics, although I had come
across his work in the past, specifically experiments he had performed in the
geophysics field.
In the middle part of our course we will spend several weeks on the economics of risk and uncertainty. We will cover a simplified version of the von Neumann and Morgenstern expected utility theory. It is good to keep in mind the limits of that theory in describing actual behavior. Allais was the first one to explain those limits. Since then the behavioral economists have amplified on why people are not rational in this way.
