We build a simple dynamic model of the business cycle with monopolistically competitive firms. With simple assumptions concerning firm entry and exit, the model can explain some important stylised facts of the business cycle which standard real business cycle models with perfect competition...

Within a class action suit, similarly injured individuals can collectively obtain compensation through the justice system. Damage averaging occurs when the compensation awarded by the court to individual members is partly or completely determined by the average damage of the class. The key role...

This paper investigates the effects of business tax lobbying in the presence of investments that are sunk or costly to adjust in the short run. We show that industries which rely more heavily on sunk capital are generally more successful in obtaining tax breaks through lobbying; this reverses...

This paper examines the time-consuming process of matching the two sides of a market each having diverse characteristics. This is cast in a labor market setting where workers of different skills need be matched with different machine qualities to produce output. I characterize the efficient...

Cet article analyse la désirabilité sociale de l'assurance de responsabilité lorsque les comportements de prévention sont imparfaitement observables. On sait que l'assurance de responsabilité est socialement avantageuse en responsabilité sans faute, même s'il y a aléa moral et que...

In this paper, we show that in a dynamic general equilibrium economy, the presence of moral hazard need not induce large cuts in optimal unemployment insurance benefits. We find that it takes a quite large proportion of "shirkers" to bend the generosity of the optimal unemployment insurance...

We obtain semiparametric efficiency bounds for the estimation of a location parameter in a time series model where the innovations are stationary and ergodic, conditionally symmetric martingale differences but otherwise possess general dependence and distributions of unknown form. We then...

Although it is intuitive and morally compelling that the worst forms of child labour should be eliminated, banning them in poor countries is unlikely to be welfare improving and can come at the expense of human capital accumulation. We show that the existence of harmful forms of child labour, in...

The paper analyzes the dynamics of a resale market subject to adverse selection. Infinitely-lived agents deal in cars which last two periods. Car quality is exogenous and known only to sellers. I prove existence of steady-state equilibrium, then provide a full characterization: number of...

In this paper, we introduce a dynamic general equilibrium model with numerous and heterogeneous investment projects and endogenous occupational choice to study a credit crunch. The investment decision is determined through the occupational choice of households which is driven by the endogenous...
