This paper offers a model of credit markets with adverse selection and
moral hazard. The equilibrium is highly inefficient, and the underlyi
ng reason is the zero-profit condition imposed by competing financial
intermediaries which gives very high powered incentives to entrepreneu
rs. The paper demonstrates that when entrepreneurs can hire a manager
to run their projects, the inefficiencies are prevented. This is becau
se the manager is not the residual claimant of the returns, and hence
has low powered incentives. Therefore, the divergence of interests bet
ween owners and managers may have beneficial effects as well as the of
ten emphasized costs. (C) 1998 Academic Press.
