Macro-Economic Equilibrium and Credit Rationing

   (509 K)

In this paper we investigate the macro-economic equilibria of an economy in which credit contracts have both adverse selection and incentive effects. The terms of credit contracts include both an interest rate and a collateral requirement. We show that in this richer model all types of borrowers may be rationed. Interest rates charged borrowers may move either pro or counter-cyclically. If pro-cyclical shocks have a greater effect on the success probabilities of risky techniques than on safe ones, then the interest rate offered depositors may also move counter-cyclically. Finally, we show that the impact of monetary policy on the macro-economic equilibrium is affected by whether or not the economy is in a regime in which credit is rationed.
