Review of Financial Studies (2025)
Abstract: Firms either enter new sectors by building on their resources or buying existing companies. Using French administrative data, we propose a measure of human capital distance between a firm and a sector of entry. Using a shift-share instrument, we show that firms build in close sectors and buy in distant sectors in terms of human capital distance. Firms build by hiring new workers, which becomes increasingly costly in distant sectors as it requires not only hiring more workers but also having more organizational capital to integrate these workers. Hence, firms buy in distant sectors to acquire already operational human capital.

Review of Financial Studies, forthcoming
Abstract: This paper investigates the impact of introducing junior unsecured loans (i.e., FinTech loans) in the small business lending market. Using French administrative data, we find that firms experience a 13% increase in bank credit after receiving a FinTech loan. We use propensity score matching procedures and a shift-share instrument to account for credit demand. The credit increase only occurs when FinTech borrowers invest in new assets, and Fintech borrowers are subsequently more likely to pledge collateral to banks. This suggests that firms use FinTech loans to acquire assets that they then pledge to banks, thereby increasing total borrowing capacity.

Abstract: This paper studies the effects of recessions on firms' customer capital. Leveraging a French reform as a financing shock, we find that, following the 2008-9 global trade collapse, financially constrained firms export less even years after the recession, as they are less likely to regain customers lost during the collapse. Our estimates indicate that winning back lost customers entails costs similar to attracting new ones, suggesting that existing customers face lower switching costs after trade interruptions. Consistent with recessions causing firms' customer capital to depreciate, we find muted effects for firms with higher ex-ante customer capital stocks.

Abstract: We use callable bonds as a laboratory to test whether relationship lending can be sustained in public financial markets. Fixed-price calls allow firms to repurchase bonds at a low price, resulting in a transfer from debtholders to equityholders. We show that following a fixed-price call, existing bondholders are less likely to participate in the firm's future bond issuances. This behavior, which resembles punishment in reputation models, is more pronounced for funds managed by large families. We also show that large-family funds behave like relationship lenders and that firms are less likely to call their bonds when there are more of them in their bondholder base. Finally, firms that develop a reputation for calling aggressively incur higher subsequent borrowing costs. Our results provide evidence of relationship lending in bond markets sustained through firm reputation.

Abstract: Does reducing the cost for entrepreneurs to write more complete contracts with their financiers enhance entrepreneurial success? To shed light on this question, this paper exploits a 2008 French reform that made it less costly for new firms to choose a legal form allowing more complete financial contracts in the company bylaws. Using comprehensive tax-filing data from 2004 to 2015, we find a marked increase in the adoption of that legal form among new firms, leading to higher growth in capital, labor, and revenues in the first three years after creation. The effects are more pronounced for firms with high marginal returns to capital, suggesting that capital misallocation decreases. Our findings highlight the significant role of legal and financial structures in entrepreneurial success, which has policy implications for promoting entrepreneurship.

Abstract: The increasing availability of microdata has enabled researchers to decompose economic shocks across multiple dimensions, such as breaking down country exports by firms, products, and destinations or analyzing city employment across industries and firms. However, this level of disaggregation presents new empirical challenges, such as accounting for the extensive margin and handling heterogeneous treatment effects when the number of observations varies nonrandomly across agents. Our research demonstrates that standard regressions using log-transformed dependent variables are biased in most settings and can misrepresent the true effects of additional controls on the elasticity of the variable of interest. To address these issues, we propose a new methodology based on the aggregation properties of arc elasticity. This approach is particularly useful for: (i) expressing the total elasticity of a shock as a weighted sum of intensive and extensive margins; (ii) disaggregating data to control for additional unobserved heterogeneity; and (iii) testing for potential spillovers and violations of the Stable Unit Treatment Value Assumption (SUTVA) in a model-free way. Our method provides a robust framework for analyzing highly disaggregated economic data, offering insights that traditional approaches may overlook.

Abstract: This paper uses a credit registry covering the quasi universe of firm-bank relationships in France for the period 1999-2016 to provide a detailed account of the role of very large borrowers ("granular borrowers") in shaping bank-level and aggregate credit variations. We document that the distribution of borrowers is fat-tailed, the top 100 borrowers representing 18% of aggregate long-term credit and 64% of total undrawn credit lines. We adapt the methodology of Amiti and Weinstein (2018) to identify the contributions of firm, bank, and aggregate shocks to credit variations at any level of aggregation. At the macroeconomic level, we show that aggregate properties of credit largely reflect granular borrowers’ shocks. This finding highlights the limitations of using time series of aggregate credit to assess the magnitude of financial frictions in the economy. At the bank-level, we find that the concentration of the borrower bases of banks exposes them to considerable borrower idiosyncratic risk and leads liquidity flows to be more synchronized across banks.
