Drawing on recent research that has identified loan rate smoothing as a significant element in lending relationships between banks and firms, the authors carry out a two-stage procedure. In the first stage, the authors derive bank-specific measures of the extent to which the banks in their sample engage in loan rate smoothing for small business borrowers in response to exogenous shocks to their credit risk. In the second stage, the authors estimate cost and (alternative) profit functions to examine how loan rate smoothing affects a banks' costs and profits. On the whole, the authors' evidence says that loan rate smoothing is associated with lower costs and lower profits. These results do not support the hypothesis that loan rate smoothing arises as part of an optimal long-term contract between a bank and its borrower. However, we do find some limited support for smoothing as part of an optimal contract for small banks early in our sample period.View the Full Working Paper
