Noise-Ridden Lending Cycles

In this paper, we use a neoclassical investment model to study the effects of imperfect information on the lending behaviour of financial intermediaries. We start by developing intuition in partial equilibrium. We model a rational financial intermediary with limited knowledge of the current state of the economy. In response to a noise shock, the intermediary lowers the interest rates on risky loans and extends relatively more credit, both of which are unaffected under perfect information. This credit boom is driven by informational rather than financial frictions and accompanied by higher aggregate default and decrease in credit spreads. We further show that these noise-ridden credit booms also survive in the general equilibrium version of the model.
