Roger Guesnerie

Roger Guesnerie is an economist born in France in 1943. He is currently the Chaired Professor of Economic Theory and Social Organization of the Collège de France, Director of Studies at the École des hautes études en sciences sociales, and the chairman of the board of directors of the Paris School of Economics.

Guesnerie studied at École Polytechnique and the École Nationale des Ponts et Chaussées, and received his doctorate in economics from the University of Toulouse in 1982. He has taught at the London School of Economics, the École Polytechnique, and at Harvard University.^[1] Guesnerie has published widely in economics, including in public economics, in the theory of incentives and economic mechanisms, and in the theory of general economic equilibrium.

Guesnerie has been elected president of several scholarly societies, notably the French Association of Economic Sciences (2002–2003), the Econometric Society (1996), and the European Economic Association (1994). Guesnerie has been elected as a foreign honorary member of the American Economic Association and as a foreign member of the American Academy of Arts and Sciences. He has served as co-editor of Econometrica (1984–1989) and as foreign editor of the Review of Economic Studies. In France, Guesnerie's research has been recognized with the CNRS Silver Medal; he has been declared to be a Chevalier de l'Ordre National du Mérite and Chevalier de la Légion d'honneur.

Donald J. Brown credited Guesnerie's "seminal" paper with the "major methodological innovation in the general equilibrium analysis of firms with pricing rules", "the introduction of the methods of nonsmooth analysis, as a [synthesis] of global analysis (differential topology) and [of] convex analysis."^[5] This paper introduced cone of interior displacements of Dubovickii and Miljutin into economics.^[6][7]

This paper stimulated a subfield of economics, devoted to pricing rules, as discussed by Jacques Drèze:

"Starting with a paper in Econometrica by Dierker, Guesnerie and Neuefeind (1985), a theory of general equilibrium has developed for economies with non-convex production sets, where firms follow well-defined pricing rules. In particular, existence theorems of increasing generality cover (to some extent, because of various differences in assumptions) the case of Ramsey-Boiteux pricing. Those interested primarily in applications might express skepticism, perhaps even horrified skepticism, upon realizing that 90 pages of a serious economics journal—a 1988 issue of The Journal of Mathematical Economics—were devoted to existence proofs of equilibrium in non-convex economies, under alternative formulations of the assumption that marginal cost pricing entails bounded losses at normalized prices. Still, I think that economic research must cover the whole spectrum from concrete applications to that level of abstraction."^[8]
