Abstract: Buyers and suppliers have diverging interests about trade-credit maturities: buyers desire long payment periods as a source of cheap funding, while suppliers prefer swift payments to avoid locking up scarce liquidity in idle assets. A fast-growing financial product innovation---supply-chain finance (SCF)---offers to resolve these diverging interests, but its net effect on suppliers is a priori unclear. We study the effects of SCF programs on suppliers using unique invoice-level data from a large Swedish bank. We find that SCF programs relax suppliers’ liquidity constraints and thereby enable them to grow their sales, employment, and investments.

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.
