Ex-Ante vs. Ex-Post Efficiency in Matching
Galichon, Alfred - 2012
Various forms of efficiency exist in the context of two-sided matching. Following Hylland and Zeckhauser (1979), an … case when the two sides of the markets have preferences, in the "marriage problem." In this case ex-ante efficiency implies … ex-post efficiency, but the converse fails: there are assignments that are ex-post efficient that are not ex …

A note on the estimation of job amenities and labor productivity
Dupuy, Arnaud; Galichon, Alfred - In: Quantitative Economics 13 (2022) 1, pp. 153-177
This paper 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. While our...

The Roommate Problem - Is More Stable Than You Think
Chiappori, Pierre-André; Galichon, Alfred; Salanié, … - 2014
Stable matchings may fail to exist in the roommate matching problem, both when utility is transferable and when it is not. We show that when utility is transferable, the existence of a stable matching is restored when there is an even number of individuals of indistinguishable characteristics...

Single market nonparametric identification of multi-attribute hedonic equilibrium models
Chernozhukov, Victor; Galichon, Alfred; Henry, Marc; … - 2019
This paper derives conditions under which preferences and technology are nonparametrically identified in hedonic equilibrium models, where products are differentiated along more than one dimension and agents are characterized by several dimensions of unobserved heterogeneity. With products...

Taxation in Matching Markets
Dupuy, Arnaud; Galichon, Alfred; Jaffe, Sonia; … - 2020
We analyze the effects of taxation in two-sided matching markets where agents have heterogeneous preferences over potential partners. Our model provides a continuous link between models of matching with and without transfers. Taxes generate inefficiency on the allocative margin, by changing who...

Canonical correlation and assortative matching: A remark
Dupuy, Arnaud; Galichon, Alfred - 2012
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...
