This paper studies the effect of credit scoring by banks on bank lending to small businesses by addressing the following questions: does credit scoring increase or decrease the propensity of banks to grant credit? Does it improve the selection of borrowers? Does credit scoring improve or reduce the likelihood that a borrower defaults on its loan? We answer these questions using a unique dataset that collects data from both a targeted survey on credit scoring models and the Central Credit Register. We rely on instrumental variables to control for the potential endogeneity of credit scoring. We find that credit scoring does not change the propensity of banks to grant loans to the generality of borrowers but helps them select borrowers. We also find that credit scoring reduces the likelihood that a borrower defaults, in particular for smaller borrowers and for banks that declare to use credit scoring mainly as a tool to monitor borrowers. These results are homogeneous across bank characteristics such as size, capital, and profitability. Overall our results suggest that credit scoring has a positive effect on the selection of borrowers and on credit performance.
