PAPER
 

We study if global supply chain relationships help firms access cross-border financing in formal international financial markets. Comparing two firms that are otherwise similar in covariates and pre-formation outcomes through a difference-in-differences strategy with matching, we find the formation of global supply chain relationships to be associated with a sustained increase in accessing of cross-border financing, across all major formal financing venues including cross-listings, bonds, syndicated loans, and M&As. Instrumenting global supply chain formation using reduction in physical trade costs yields similar results. This finding is also robust to controlling for strategic disclosure concerns. The estimated effect is stronger for firms in environments with higher accounting and ethical standards and small and growing firms, but weaker for firms in countries with tighter capital controls and more volatile exchange rates. This suggests global supply chain formation helps cross-border financing more through information production, not cash flow relocation or re-denomination.

1. "Credit Risk Propagation along Supply Chains: Evidence from the CDS Market,"

with Senay Agca, Volodymyr Babich, and John R. Birge, major revision at Management Science, media at ChicagoBoothReview.

We find that credit risk propagates through multiple supply chain tiers for both positive and negative credit shocks. Specifically, rating and industry-adjusted CDS spreads change by 44-71 bps for the first tier. Strong propagation persists for 2nd and 3rd tiers for adverse shocks but attenuates for favorable shocks. Such effects are not observed for inactive supply chain links. Credit risk propagation is magnified with longer-term supply-chain relations, trade credit, differentiated products, and leverage, but is moderated with investment grade rating and high inventory. Credit risk propagation is stronger for supply chain partners followed by the same analysts.

2. "The Impact of COVID-19 on Supply Chain Credit Risk,"

with Senay Agca, John R. Birge, and Zi'ang Wang.

We examine how supply chain activity reflects into credit risk during different phases of the COVID-19 by focusing on CDS spreads and US-China supply chain links. We find considerable effects on credit risk. During the economic shutdown of the pandemic, CDS spreads increase with supply chain disruptions and spreads go down when the activity resumes with re-opening of the economy. The household demand channel is an important driver of how supply chains reflect in credit risk. Supply chain activity resumption is not sufficient in sectors that cater to households when the local economy suffers from dampened household demand due to economic shutdowns. Such effects are not observed for sectors that cater more to businesses. While firm leverage, product market competition, and supply chain duration magnify the impact of supply chain activity on credit risk during the pandemic, cash holdings, capital redeployability, growth opportunities, and investment-grade rating moderate such effects.

 

3. "Global Supply Chains and Cross-Border Financing,"

We study if global supply chain relationships help firms access cross-border financing in formal international financial markets, using a comprehensive dataset of global supply chain relationships and cross-border financing deals. Comparing two firms that are otherwise similar in covariates and pre-formation outcomes through a difference-in-differences strategy with matching, we find that formation of global supply chain links is positively associated with a sustained increase in cross-border financing across bond, cross-listing, syndicated loans and M&A markets. This association is robust to controlling for standard firm-level determinants, industry-specific and country-specific shocks, and endogeneity. We examine multiple economic channels. We establish an important informational channel for the relation between global supply chain integration and cross-border financing, supported by a battery of tests, including heterogeneity, regression discontinuity, and supply chain voluntary disclosure. We do not find capital control, currency risks, or external financing dependence to be as important. 

 

4. "The Financing Role of Inventory: Evidence from China’s Metal Industries,"

with Vernon Hsu, major revision at Management Science.

(Featured at 2019 CSAMSE Best Paper Award)

Inventory theory suggests that inventory plays vital roles in the matching of demand and supply. We provide theoretical and empirical evidence that inventory can play a significant financing role in practice. In the context of global supply chain transaction, we develop a model to show that inventory can be leveraged to take advantage of the financial arbitrage opportunities in markets with frictions. Empirically, we first use country-level data in China to test the model prediction after controlling for input price trajectory, currency risk, industrial demand, and economic uncertainty. We then confirm the strong financing role of inventory at the firm-level using data from China’s metal processing industries after controlling for demand, lead-time, profitability, capacity, and firm size. We further substantiate that the firms who use inventory as a financing tool indeed increase their short-term debts.

5. "Not Coming Home: Trade and Economic Policy Uncertainty in American Supply Chain Networks,"

with Ben Charoenwong and Miaozhe Han, submitted, media at CUHK, Business Insider, MorningstarReuters观察者网.

(Featured at 2020 ADBI PRN Joint Conference)

We study the effect of American trade policy uncertainty (U.S. TPU), American non-trade economic policy uncertainty (U.S. EPU), and foreign economic policy uncertainty (foreign EPU) on the supply chain network of American public firms. As a motivating example, we find firms with more domestic suppliers increase foreign supplier relationships even before the onset of the China-U.S. trade war in March 2018, beginning around the time of President Trump’s campaign bid. In reduced-form analyses, we find higher U.S. TPU predicts trade creation – rather than bringing production “home”, American firms’ supplier and customer bases tilt abroad when U.S. TPU increases. The tilt is also associated with lower long-term strategic investments and asset growth. Meanwhile, foreign-country EPU shocks lead to trade diversion to other foreign countries. Firms for which production shocks would be more severe and those more central to the production network respond more to all measures of economic policy uncertainty.
