How are neighboring firms affected when a bank learns more about a given firm? We analyze exchange-rate-induced movements of Peruvian firms across a threshold that governs their regulatory treatment by banks. Firms that cross the threshold supply more information to their banks and experience a substantial increase in financing. We find positive spillover effects: the neighbors of the above-threshold firms also experience increased financing. These spillovers are confined to neighbors sharing a bank, and the performance of new loans to these neighbors improves, suggesting that the bank has become better informed about other local firms.

We show that business microloans to U.S. subprime borrowers have a very large impact on subsequent firm success. Using data on startup loan applicants from a lender that employed an automated algorithm in its application review, we implement a regression discontinuity design assessing the causal impact of receiving a loan on firms. Startups receiving funding are dramatically more likely to survive, enjoy higher revenues, and create more jobs. Loans are more consequential for survival among subprime business owners with more education and less managerial experience.
