Reference excerpt

Pierre-André Chiappori is a French-Monégasque economist who is currently the E. Rowan and Barbara Steinschneider Professor of Economics at Columbia University. His research focuses on household behavior, general equilibrium and mathematical economics. He has been the Counsellor of Finance and Economy since 18 March 2024.

Education Chiappori studied at the École normale supérieure in Paris between 1974 and 1979. During that period, he also studied at various Parisian universities, receiving degrees in mathematics, statistics, and economics. He graduated with a Ph.D. in economics from the Université Paris I Panthéon-Sorbonne in 1981.

Career Chiappori's first academic post was as an assistant professor at his alma mater, the Paris 1 Panthéon-Sorbonne University. He then became a maître de conférences at the École des hautes études en sciences sociales in 1985, followed by an appointment at the CNRS and the École Polytechnique. He became a professor of economics at the ENSAE in 1992, while simultaneously serving as a senior researcher at the CNRS. He left France to take up a professorship at the University of Chicago in 1997, and took up his current position at Columbia University in 2005, after serving for a year as a visiting professor at Columbia. He has served as an editor of various journals, including the Review of Economics of the Household, the Journal of Political Economy and the Journal of the European Economic Association. He was elected a Fellow of the Econometric Society in 1995, and as a Fellow of the European Economic Association and 2004. In 2015 he was made a Fellow of the Society for the Advancement of Economic Theory. In Monaco, he had chaired the scientific council of the Monegasque Institute of Statistics and Economic Studies since 2011, and he was also a member of the advisory board of International University of Monaco. Prince of Monaco appointed him as the Counsellor of Finance and Economy on 18 March 2024.

Worked examples

Example 1 — a first encounter with Pierre-André Chiappori

Start with the simplest possible case. Write down what Pierre-André Chiappori claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Pierre-André Chiappori 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 Pierre-André Chiappori 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 Pierre-André Chiappori

In research: Pierre-André Chiappori appears in astronomy 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 Pierre-André Chiappori 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: Pierre-André Chiappori is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of the School for Advanced Studies in the Social Sciences, Academic staff of École polytechnique, Columbia University faculty, so understanding it makes those chapters shorter.
In everyday life: Look for Pierre-André Chiappori 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.
