We revisit the signalling hypothesis, whereby potential employers use the duration of unemployment as a signal as to the productivity of applicants. We suggest that the quality of such a signal is very low when the unemployed receive unemployment benefits: individuals have good reasons to remain...

This paper provides a method to single out customer-based discrimination in the housing market. We build a matching model with ethnic externalities where landlords differ in the number of housing units they own within the same building. Multiple-dwelling landlords discriminate more often than...

This paper provides a game-theoretical analysis of the use by athletes of performance-enhancing drugs. We focus on a two-player game where players are heterogeneous and performances are subject to uncertainty. While the standard setup assumes these drugs increase maximum performances, we assume...

The paper investigates the link between the over-exposure of African immigrants to unemployment in France and their under-representation in jobs in contact with customers. We build a two-sector matching model with ethnic sector-specific preferences, economy-wide employer discrimination, and...

We propose a search equilibrium model in which homogenous …rms post wages along with a vacancy to attract job-seekers, while homogenous unemployed workers invest in costly job-seeking. The key innovation relies on the organization of the search market and the search behavior of the job-seekers....

We propose a search equilibrium model in which homogenous firms post wages along with a vacancy to attract job-seekers, while homogenous unemployed workers invest in costly search. The key innovation relates to the organisation of the search market and the search behaviour of the job-seekers....

L'amour lorsqu'il est poussé à son paroxysme confine à l'étouffement. Telle est la morale de cet article dans lequel un parent altruiste module son offre de travail en partie pour assurer le meilleur niveau de vie possible à son enfant. Lorsque le travail des parents et celui des enfants...

This paper presents a continuous time overlapping-generation (OLG) model which generalizes the Blanchard-Buiter-Weil model and clarifies the relationships between dynastic previous termaltruismnext term, the length of planning horizons, and dynamic inefficiency. Our main innovation relies on the...

We propose a search equilibrium model in which homogenous …rms post wages along with a vacancy to attract job-seekers, while homogenous unemployed workers invest in costly job-seeking. The key innovation relies on the organization of the search market and the search behavior of the job-seekers....

Should education become more vocational or more general? We address this question in two steps. We first build and solve a two-sector matching model with generalists and specialists. Generalists pursue jobs in both sectors; however, they come second in job queues. Specialists seek for jobs in a...
