Abstract
We analyze consumer defaults in a sample of 64,000 customers taking personal loans from a Korean bank. Applying a Generalized Additive Modeling (GAM) framework, we show a non-linear impact of loan and borrower characteristics. In particular, the likelihood of default is high for both low income borrowers as well as high income borrowers. Our results are robust to a range of different tests, and highlight the usefulness of the GAM framework, especially the graphical presentation of non-linearities.
