|December 2015||Specialization in Bank Lending: Evidence from Exporting Firms|
with Daniel Paravisini, Philipp Schnabl: w21800
We develop an empirical approach for identifying specialization in bank lending using granular data on borrower activities. We illustrate the approach by characterizing bank specialization by export market, combining bank, loan, and export data for all firms in Peru. We find that all banks specialize in at least one export market, that specialization affects a firm’s choice of new lenders and how to finance exports, and that credit supply shocks disproportionately affect a firm’s exports to markets where the lender specializes in. Thus, bank market-specific specialization makes credit difficult to substitute, with consequences for competition in credit markets and the transmission of credit shocks to the economy.
|August 2015||Intrafirm Trade and Vertical Fragmentation in U.S. Multinational Corporations|
with Natalia Ramondo, Kim J. Ruhl: w21472
Using firm-level data, we document two new facts regarding intrafirm trade and the activities of the foreign affiliates of U.S. multinational corporations. First, intrafirm trade is concentrated among a small number of large affiliates within large multinational corporations; the median affiliate ships nothing to the rest of the corporation. Second, we find that the input-output coefficient linking the parent’s and affiliate’s industries of operation—a characteristic commonly associated with production fragmentation— is not related to a corresponding intrafirm flow of goods.

|April 2011||Dissecting the Effect of Credit Supply on Trade: Evidence from Matched Credit-Export Data|
with Daniel Paravisini, Philipp Schnabl, Daniel Wolfenzon: w16975
We estimate the elasticity of exports to credit using matched customs and firm-level bank credit data from Peru. To account for non-credit determinants of exports, we compare changes in exports of the same product and to the same destination by firms borrowing from banks differentially affected by capital-flow reversals during the 2008 financial crisis. We find that credit shocks affect the intensive margin of exports, but have no significant impact on entry or exit of firms to new product and destination markets. Our results suggest that credit shortages reduce exports through raising the variable cost of production, rather than the cost of financing sunk entry investments.

|June 2010||Risk Aversion and Wealth: Evidence from Person-to-Person Lending Portfolios|
with Daniel Paravisini, Enrichetta Ravina: w16063
We estimate risk aversion from the actual financial decisions of 2,168 investors in Lending Club (LC), a person-to-person lending platform. We develop a methodology that allows us to estimate risk aversion parameters from each portfolio choice. Since the same individual makes repeated investments, we are able to construct a panel of risk aversion parameters that we use to disentangle heterogeneity in attitudes towards risk from the elasticity of investor-specific risk aversion to changes in wealth. In the cross section, we find that wealthier investors are more risk averse. Using changes in house prices as a source of variation, we find that investors become more risk averse after a negative wealth shock. These preferences consistently extrapolate to other investor decisions within LC.
