Abstract

[fre] Dans une économie de type Arrow-Debreu, tous les risques sont partagés efficacement à l'équilibre. Ce résultat est en contradiction avec le fait que de nombreux risques dans nos économies ne sont pas assurés, et que d'autres sont couverts seulement au travers d'un système centralisé. C'est le cas pour de nombreux risques associés à l'environnement, à la technologie, au capital humain... Dans cet article, nous passons en revue les différents arguments qui ont été développés au cours des vingt dernières années par les économistes pour expliquer les limites de l'assurabilité par des marchés concurrentiels. Outre les coûts de transaction, la sélection adverse et le risque moral (ex ante et ex post), nous avons examiné les arguments fondés sur la taille des pertes, sur les faibles probabilités, sur la responsabilité limitée, sur l'ambiguïté et sur certains aspects dynamiques des risques. [eng] Towards an economic theory of the limits of insurability . In an Arrow-Debreu economy, all risks are shared efficiently at equilibrium. This result is in contradiction with the fact that many risks in our economies are not insured, and that others are covered only through a non-market system. This is the case for many risks associated to environment, technology, human capital,... In this paper, we review the different arguments that have been developped during the last twenty years by economists to explain the limits of insurability by competitive markets. In addition to transaction costs, adverse selection and (ex ante and ex post) moral hazard, we examined arguments based on the size of losses, on low probabilities, on limited liability, on ambiguity and on some dynamic aspects of risks.
