Abstract

With information asymmetry between contracting parties, adverse selection may result. A separation may be achieved if low-risk types can signal their identity—for example, by selecting from a menu of price-quantity contracts. In such models, signaling is costly and solutions are, at best, second best. These models characterize risk types by differences in the probability, rather than in severity, of the costs they impose. However, when severity differences also are considered, first best solutions become feasible. We identify the circumstances in which costly separating equilibria prevail and those in which full-information equilibria can be attained.
