Working papers

Abstract: The increasingly lengthy trade credit maturity creates uncertainty and financial constraints for suppliers. Using novel invoice-, contract-, and firm-level data, this paper studies how a recent innovation in trade credit industry---Supply Chain Finance (SCF)---reduces suppliers' financial constraints and improves supply chain efficiency. We compare SCF with traditional factoring and document its effects. Preliminary analyses show that both suppliers and buyers reduce their borrowing of bank debt upon joining the program. While suppliers see an increase in employment, sales, and investment, buyers are largely unaffected. Overall, evidence suggests that SCF increases supply chain efficiency but also raises the concern over hidden debt.

Abstract:   We document the effects of higher borrowing cost on private firms in the presence of financial frictions by exploiting a quasi-experiment and a unique and comprehensive dataset from Sweden. In June 2010, the central bank of Sweden increased the repo rate unexpectedly and exposed firms with long term loan maturing right before or after the hike to different cost of borrowing. Consistent with the debt overhang theory, we find that higher cost of borrowing has a significant negative effect on investment, but more for highly levered firms. These results are robust to carefully controlling for firms' credit demand. Our findings highlight the importance of balance sheet heterogeneity in the responsiveness of firms to interest rate shocks.

Abstract: This paper investigates how cross-selling affects relationship lending with internal data of a large bank and the Swedish credit registry. I show that within a bank-firm relationship, profit earned from non-loan products cross-subsidizes loans and increases 1) credit supply and 2) lenience in delinquency. For identification, I exploit the Basel II-induced exogenous variation in products' profitability while holding constant the firms' creditworthiness and relationship informativeness. I find that the average affected firms experienced a decrease of 6.1% ($400,000) in credit supply and 24% (9.9 pp) in lenience in delinquency.  The results inform optimal regulatory design for lenders who multi-produce.
