Cream Skimming, Dregs Skimming, and Pooling: On the Dynamics of Competitive Screening

Diderik Lund, Tore Nilssen

Abstract

We discuss the existence of a pooling equilibrium in a two-period model of an insurance market with asymmetric information. We solve the model numerically. We pay particular attention to the reasons for non-existence in cases where no pooling equilibrium exists. In addition to the phenomenon of cream skimming emphasized in earlier literature, we here point to the the importance of the opposite: dregs skimming, whereby high-risk consumers are profitably detracted from the candidate pooling contract.
