α: calibrated so average coauthorship-adjusted count equals average raw count
The quality of bank lending is increasingly viewed as a force driving the buildup and unfolding of crises. In a dynamic general equilibrium model, we show that banks’ access to liquidity and the values of loan portfolios govern banks’ incentives and effectiveness in producing information on loans. Consistent with granular loan-level evidence from US banks, the calibrated model predicts that loan due diligence deteriorates during expansions and intensifies during contractions. This countercyclicality attenuates investment and output effects of liquidity shocks but can moderately amplify loan quality shocks. Credit policies may dilute stabilizing effects of due diligence.
