Description:
<jats:p> Nonexclusive sequential borrowing can increase default and impose externalities on prior lenders. We document that sequential banking is pervasive with substantial effects. Using credit card applications from a large bank and data on the applicants’ entire loan portfolios, we find that an additional credit line causes a 5.9 percentage point decline in default for high-score borrowers on previous loans. However, for low-score borrowers, it causes a 19 percentage point increase. The former use the new credit to smooth payments on preexisting loans, while the latter increase their total debt. These results have implications for “ no-universal-default” regulation and financial inclusion. (JEL D62, D82, G21, G51) </jats:p>
