Abstract

Seminal papers on asymmetric information in competitive insurance markets, analysing the monetary deductible as a screening device, show that any existing equilibrium is of a separating type. High risks buy complete insurance whilst low risks buy partial insurance - and this result holds for Nash behaviour as well as for Wilson foresight. In this paper, we analyze the strength of screening based on limitations to the period of coverage of the contract. We show that in this case a) the Nash equilibrium may entail low risks purchasing any insurance at all and b) under Wilson foresight, a pooling equilibrium may exist.
