Long-run trends in increased access to credit are thought to improve real activity. However, “rapid” credit expansions do not always end well and have been shown in the academic literature to predict adverse real outcomes such as lower GDP growth and an increased likelihood of crises. Given these financial stability considerations associated with rapid credit expansions, being able to distinguish in real time “good booms” from “bad booms” is of crucial interest for policymakers. While the recent literature has focused on understanding how the composition of borrowers helps distinguish good and bad booms, in this post we investigate how the composition of lending during a credit expansion matters for subsequent real outcomes.
