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

Diderik Lund and Tore Nilssen ()

No 01-2003, Working Papers from Copenhagen Business School, Department of Economics

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 phenom-

enon of cream skimming emphasized in earlier literature, we here point

to the the importance of the opposite: dregs skimming, whereby high-risk

consumers are proÞtably detracted from the candidate pooling contract.
