Cet article examine en détail les allocations d’assurance de second-rang dans une économie soumise à l’antisélection. Partant d’une extension naturelle du modèle classique, nous supposons une perception imparfaite du risque. Nous caractérisons les contraintes qui s’exercent sur la...

We study imperfect competition between insurers in a multiple-risk environment. In the absence of asymmetric information, equilibria are efficient, and we determine the degrees of specialization under which the specialized insurers are able or unable to capture the surplus. We show in contrast...

The present paper thoroughly explores second-best efficient allocations in an insurance economy with adverse selection. We start with a natural extension of the classical model, assuming less than perfect risk perception. We characterize the constraints on efficient redistribution, and we...

We study imperfect competition between insurers in a multiple-risk environment. In the absence of asymmetric information, equilibria are efficient, and we determine the degrees of specialization under which the specialized insurers are able or unable to capture the surplus. We show in contrast...

We define a repairable asset as an irreplaceable commodity whose quality is at risk, but can be partly restored at a cost. Examples are houses, automobiles and, especially, health, for which standard monetary approaches are oversimplified. To optimize the value of insurance, the insurer and the...

I examine competition in the sector of mortgage life insurance, in particular the Periodic Switching Right (PSR), by which the borrower can change his insurer once every period (say, every year). The PSR is likely to have pro competitive effects (lower premium), but by the same move, to lead to...

This paper addresses the urbanization of areas exposed to natural disasters and studies its dependency on land-use and insurance policies. The risk-map paradox that we describe explains why an insurance system with simplistic maps and tariffs is the rule. Indeed, in practice we observe simple...
