Roger Guesnerie: An Hors Catégorie Career

Abstract

This profile of Roger Guesnerie is based on several interviews with him between September 2018 and June 2019. The interviews took place at Roger s office, at the College de France in the fifth arrondissement of Paris, just near the Pantheon. The objective of the profile is twofold. First, we trace the career of this highly influential theoretical economist who made seminal contributions to the fields of general equilibrium, taxation, contract theory, sunspot, and rational expectations. Second, we show how Guesnerie and his colleagues contributed to changing the French landscape of economic research.
