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...

In this paper we view child labor as a negative externality exerted by some poor countries on richer nations. The practice of child labor can thus be used by the poor to extract some form of compensation over time. We build a two-country growth model with international externality. We then...

In this paper, we adopt the usual assumptions of the collective approach, i.e. individualism and efficiency, to study household labor supply. The theoretical innovation is twofold. First, we incorporate the decision to participate in the labor market in the initial setting. Second, we abandon...

From the mid 1980's, the Canadian government froze or cut back the major traditional provisions targeted towards families with children. Faced with the lowest (and declining) fertility rate in Canada, the government of the province of Québec (where the population is mostly French) decided in...

We show how a Schumpeterian process of creative destruction can induce rational, herd-behavior by entrepreneurs across diverse sectors of the economy that may look like it is fuelled by ``animal spirits''. Consequently, a multi-sector economy, in which sector-specific, productivity improvements...
