We experimentally study the impact of substantially larger enterprise loans, in collaboration with an Egyptian lender. Larger loans generate small average impacts, but machine learning using psychometric data reveals dramatic heterogeneity.

The magnitude of this difference implies that an individual lender’s credit allocation choices matter for aggregate income.
