Alfred Galichon

Research Fellow

New York University

Alfred Galichon is a Professor of Economics at Sciences Po, Paris, which he joined in 2012. Prior to that, he was a Professor at Ecole Polytechnique, and he had been a visiting professor at Columbia University and at the University of Chicago, Booth School of Business.

Pr. Galichon’s research interests range widely from theoretical to empirical questions and include Econometrics, Economic theory, and Quantitative Finance. His research is motivated by the desire to understand the decisions of economic agents – investment, insurance, marriage, transportation – using advanced quantitative methods, and has been published in journals such as the Journal of Econometrics, Econometrica, the Review of Economic Studies, the Journal of Economic Theory, and Mathematical Finance. He is a member of several Editorial Boards including the Review of Economic Studies and Economic Theory. In 2012, he has been one of the recipients of the European Research Council (ERC) Grants awarded by the European Commission for his research on matching markets. In 2010 he was nominated for the best French young economist award by the Cercle des Economistes and Le Monde newspaper.

In addition to his academic research, Pr. Galichon also has served as a consultant or a collaborator to various organizations including Goldman Sachs, EDF, Lafarge, and Air France. Alfred Galichon received his Ph.D. in Economics from Harvard University in 2007 and his B.Sc. from Ecole Polytechnique (X97) in 2000. He is a Chief Engineer of Corps des Mines (Ingénieur en chef des Mines) and a Research Fellow of the Center for Economic Policy Research (CEPR).

He joined IZA as a Research Fellow in January 2014.



IZA Discussion Paper No. 10900

This note introduces a maximum likelihood estimator of the value of job amenities and labor productivity in a single matching market based on the observation of equilibrium matches and wages. The estimation procedure simultaneously fits both the matching patterns and the wage curve. Our estimator is suited for applications to...

In this paper, we address the problem of estimating transport surplus (a.k.a. matching affinity) in high dimensional optimal transport problems. Classical optimal transport theory species the matching affinity and determines the optimal joint distribution. In contrast, we study the inverse problem of estimating matching affinity based on the observation of...

This paper contributes to the literature on hedonic models in two ways. First, it makes use of Queyranne's reformulation of a hedonic model in the discrete case as a network flow problem in order to provide a proof of existence and integrality of a hedonic equilibrium and efficient computational techniques...

Which and how many attributes are relevant for the sorting of agents in a matching market? This paper addresses these questions by constructing indices of mutual attractiveness that aggregate information about agents' attributes. The first k indices for agents on each side of the market provide the best approximation of...

In the context of the Beckerian theory of marriage, when men and women match on a single-dimensional index that is the weighted sum of their respective multivariate attributes, many papers in the literature have used linear canonical correlation, and related techniques, in order to estimate these weights. We argue that...
