Title: Market Failure in a Credit-Rationed Economy
Abstract: This paper studies a simple two-period general equilibrium model of a competitive economy with
endogenous "Type one" credit rationing. It is shown that an equilibrium will generally not be efficient, in the
absence of corrective policies. The nature of the market failure, and of optimal government policy, is then
examined. Underinvestment in individual firms can be corrected by interest subsidies or similar instruments,
while taxes are needed to penalize excessive levels of default that would otherwise occur in equilibrium. These
policies are interpretable in the spirit of Pigovian taxes and subsidies.
