Concurrence et antisélection multidimensionnelle en assurance

Abstract

ln the Rothschild and Stiglitz model, assuming differences in risk aversions may lead to unusual equilibrium configurations like multiple equilibria, equilibrium positive profits, or random contracts. We characterize the various types of equilibria and give results on the determinants of the equilibrium regime. We conclude with a few remarks on classical equilibrium concepts in insurance economics, and we suggest policy implications.
