Screening equilibria in experimental markets

Abstract

We conduct an experimental test of a screening model of an insurance market with asymmetric information. We first conduct three sessions in which the proportion of high risk buyers is such that a separating equilibrium should exist. We then conduct three more sessions in which the only change we make is decreasing the proportion of high risks such that the equilibrium is now a pooling equilibrium. In both treatments, the observed behavior converges to the equilibrium prediction. The Geneva Risk and Insurance Review (2007) 32, 147–167. doi:10.1007/s10713-007-0007-z
