Key takeaways

  • Maurice Allais belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Maurice Allais to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Maurice Allais from memory before moving on to harder problems.

Reference excerpt

Maurice Félix Charles Allais (French pronunciation: [mɔʁis feliks ʃaʁl alɛ]; 31 May 1911 – 9 October 2010) was a French physicist and economist, the 1988 winner of the Nobel Memorial Prize in Economic Sciences "for his pioneering contributions to the theory of markets and efficient utilization of resources", along with John Hicks (Value and Capital, 1939) and Paul Samuelson (The Foundations of Economic Analysis, 1947), to neoclassical synthesis. They formalize the self-regulation of markets, which Keynes refuted but reiterated some of Allais's ideas. Born in Paris, France, Allais attended the Lycée Lakanal, graduated from the École Polytechnique in Paris and studied at the École nationale supérieure des mines de Paris. His academic and other posts have included being Professor of Economics at the École Nationale Supérieure des Mines de Paris (since 1944) and Director of its Economic Analysis Centre (since 1946). In 1949, he received the title of doctor-engineer from the University of Paris, Faculty of Science. He also held teaching positions at various institutions, including at the university of Paris X–Nanterre. His first works oriented him towards the sciences of the concrete and the experiments of fundamental physics, on which he will also publish numerous works, notably on pendular oscillations and the laws of gravitation. It's after a trip in 1933 to the United States during the Great Depression, that he decides to make the economy. Allais died at his home in Saint-Cloud, near Paris, at the age of 99. Allais considered Léon Walras, Wilfredo Pareto, and Irving Fisher to be his primary influences. He was reluctant to write in or translate his work into English, and many of his major contributions became known to the dominant community only when they were independently rediscovered or popularized by English-speaking economists. At the same time, he claimed Keynes's liberalism and declared himself in favor of an important public sector. Allais attended the inaugural meeting of the Mont Pelerin Society, but he was alone among the attendees to refuse to sign the statement of aims because of a disagreement over the extent of property rights. He exerted an important influence, at the end of the war, on French economists such as Gérard Debreu, Jacques Lesourne, Edmond Malinvaud and Marcel Boiteux. Paul Samuelson said "Had Allais earliest writings been in English, a generation of economic theory would have taken a different course", and felt the Nobel Prize should have been awarded to him much earlier. Assar Lindbeck, the chairman of the selection committee, considered Allais as "a giant within the world of economic analysis".

Economist Author of several theoretical and applied economics studies, his work has focused on the development of mathematical economics, especially in the fields of general equilibrium theory, capital theory, decision theory, and monetary policy. A pioneer in macroeconomic monetary analyses, the economist has been authoritative for his theoretical studies of risk, illustrated by his famous paradox: "the less the risk is, the more speculators flee." He has also been a pioneer in various fields such as the role of central banks and the pricing of public services.

Inspired at first by Walras His first book develops the microeconomic aspect. With Traité d'économie pure, which he wrote between January 1941 and July 1943, based on his contributions, along with Hicks and Samuelson, to the concept of neoclassical synthesis. He anticipates several of the propositions and theorems put forward by Hicks, Samuelson and others, sometimes giving them a more general and rigorous formulation. In particular, he demonstrates the equivalence theorems that Kenneth Arrow and Gérard Debreu will find in 1954: "Every equilibrium situation in a market economy is a situation of maximum efficiency, and reciprocally, every situation of maximum efficiency Is a equilibrium situation in a market economy." The market thus ensures economic efficiency and optimal distribution of income in the nation. At the same time, Samuelson exposed the process of trial and error which leads to the equilibrium of markets. In 1947, in the second part of his work Économie et Intérêt, Allais introduced time and currency and thus tackled the dynamics and growth of capitalist economies. Again, he made several proposals, that would be later attributed to other, better-known economists. He introduced the first overlapping generations model(OLG model) (later popularized and attributed to Paul Samuelson in 1958), introduced the golden rule of optimal growth before Trevor Swan and Edmund Phelps, show that an interest rate equal to the growth rate maximizes consumption. He also described the transaction demand for money rule before William Baumol and James Tobin He was also responsible for early work in Behavioral economics, which in the US is generally attributed to Daniel Kahneman and Amos Tversky. In the 1940s, Allais worked on "decision theory" (or "theory of choice") under uncertainty and developed a theory of cardinal utility. Due to war conditions and his commitment to publish in French, his work was undertaken independently of Theory of games and economic behavior developed by John von Neumann and Oskar Morgenstern. He formulated the Allais paradox in 1953, which questions the traditional model of rationality of choices and contradicts the expected utility hypothesis.

Liberalism and socialism Although he participated in the Mont Pelerin Society, Allais was convinced of an affinity between liberalism and socialism, stating: "'For the true liberal, as for the true socialist, it matters little whether the means of production are privately or collectively owned, so long as the essential goals they pursue, namely efficiency and justice, are achieved." He advocated "competitive planning" as a "possible synthesis of liberalism and socialism." Bruce Caldwell states: "Allais disagreed with the group's stance on private property, this on vaguely Georgist lines." In 1959, he and other French members of Mont Pelerin such as Jacques Rueff established an organization, Mouvement pour une société libre, which spoke readily of a social liberalism that would go "beyond laissez-faire and socialism."

Worked examples

Example 1 — a first encounter with Maurice Allais

Start with the simplest possible case. Write down what Maurice Allais claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Maurice Allais before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Maurice Allais ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Maurice Allais

In research
Maurice Allais appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Maurice Allais in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Maurice Allais is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1911 births, 2010 deaths, 20th-century French physicists, so understanding it makes those chapters shorter.
In everyday life
Look for Maurice Allais outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
