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...

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 consider a formal approach to comparative risk aversion and applies it to intertemporal choice models. This allows us to ask whether standard classes of utility functions, such as those inspired by Kihlstrom and Mirman [15], Selden [26], Epstein and Zin [9] and Quiggin [24] are well-ordered...
