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 …

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...

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...

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...

A Note on the Estimation of Job Amenities and Labor Productivity

Dupuy, Arnaud; Galichon, Alfred - 2017

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...

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...

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...

Ordinal and Cardinal Solution Concepts for Two-Sided Matching

Echenique, Federico - 2014

We characterize solutions for two-sided matching, both in the transferable - and in the nontransferable - utility frameworks, using a cardinal formulation. Our approach makes the comparison of the matching models with and without transfers particularly transparent. We introduce the concept of a...
