Dans l'analyse des problèmes d'antisélection en assurance, on suppose généralement que la richesse des individus est une variable aléqtoire binaire, selon que l'individu subit ou non une perte. Ceci interdit d'analyser la forme du contrat d'assurance partielle destiné aux individus à...

We provide a condition for ranking of information systems in agency problems. The condition has a straightforward economic interpretation in terms of the sensitivity of a cumulative distribution with respect to the agent's effort. The criterion is shown to be equivalent to the mean preserving...

We provide sufficient conditions for the first-order approach in the principal-agent problem when the agent’s utility has the non-separable form u(y - c(a)) where y is the contractual payoff and c(a) is the money cost of effort. We first consider a decision-maker facing prospects which cost...

In this paper we treat an individual’s health as a continuous variable, in contrast to the traditional literature on income insurance, where it is assumed that the individual is either able or unable to work. A continuous treatment of an individual’s health sheds new light on the role of...

Increasing emphasis has been placed on the need for an effective lender of last resort for sovereign states and on procedures for sovereign debt restructuring to help cope with global financial crises. Where private creditors use short-term debt to check sovereign debtor’s moral hazard, there...

We use a principal-agent framework to reexamine the implications of the negligence and strict liability rules when the tort-feasor is an agency. We assume a unilateral care situation and consider both the cases of moral hazard and of adverse selection. In both instances the negligence rule is...

This paper analyzes the trade-off between monitoring and incentives in a principal-agent relationship with moral hazard. We derive general results on the optimal monitoring-incentives mix for the case where both parties are risk-neutral and the agent faces a limited liability constraint. We show...

Does the average level of sickness absence in a neighborhood affect individual sickness absence through social interaction on the neighborhood level? To answer this question, we consider evidence of local benefit-dependency cultures. Well-known methodological problems in this type of analysis...
