In … order to get results for all strictly risk-averse expected utility maximizers, the concept of “stochastic increasingness” is … used. Different assumptions on the stochastic dependence between the insurable and uninsurable risk lead to different …

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 … strong adverse selection.
