On décrit, dans cette revue, les articles récents qui se sont attachés à construire des méthodes empiriques structurelles pour estimer les préférences des agents, étudiants et universités, ou élèves et écoles, qui participent à des mécanismes d'allocation centralisée. Ces recherches empiriques s'...

Humans have evolved in populations structured in groups that extended beyond the nuclear family.

The aim of this paper is to construct a robust nonparametric estimator for the production frontier. We study this problem under a regression model with one-sided errors where the regression function defines the achievable maximum output, for a given level of inputs-usage, and the regression error...

We analyze the consequences of noisy information aggregation for investment. Market imperfections create endogenous rents that cause overinvestment in up-side risks and underinvestment in downside risks. In partial equilibrium, these inefficiencies are particularly severe if upside risks are...

This paper discusses the effects of horizontal mergers on innovation. We rely on the existing academic literature and our own research work to present the various positive and negative effects of mergers on innovation. Our analysis shows that, even in the absence of technological spillovers and R...

Aggregate productivity growth in the U.S. has slowed down since the 2000s. We quantify the importance of differential productivity growth across occupations and across industries, and the rise of computers since the 1980s, for the productivity slowdown. Complementarity across occupations and...

We study the price and welfare effects of collusion between two-sided platforms and show that they depend on whether collusion occurs on both sides or a single side of the market, and whether users single-home or multi-home. Our most striking result is that one-sided collusion leads to lower (resp...
