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 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...

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...

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....

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...

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....

Nous montrons à l’aide de l’enquête Logement que les personnes d’origine africaine sont surreprésentées dans les grandes agglomérations et tendent à s’y fixer dans des proportions beaucoup plus importantes que les personnes d’origine française. Deux raisons expliquent ce...

In this paper, we provide an altruistic interpretation to the Blanchard (1985) perpetual youth model and examine under which conditions such interpretation holds. Unlike the standard model, the modified model essentially requires no insurance and a bequest nonnegativity constraint.

This article proposes a multi-sector matching model where workers have (symmetric) sector-specific skills and the search market is segmented by sector. Workers choose the range of markets they are willing to participate in. I identify a composition externality: Workers do not take into account...
