Equilibrium in competitive insurance markets with ex ante adverse selection and ex post moral hazard
Existence of pure strategy equilibria is studied in insurance markets that exhibit both ex ante adverse selection of the Rothschild-Stiglitz-Wilson type, and ex post hidden information moral hazard. It is found that ex post moral hazard has two offsetting effects on the existence of equilibrium, and that in general it is difficult to say whether an equilibrium is more or less likely to exist.
