The author presents a simple model of personal finance in which an incumbent lender has an information advantage vis-a-vis both potential competitors and households.

Unless rival lenders are equally well informed, competition may reduce welfare. This holds, in particular, if less informed rivals can free ride on the incumbent’s superior screening ability.
