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.​

(Featured at 2018 SFS Cavalcade, 2018 NFA, 2018 EEA)

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

with Michael Hertzel, Jie Peng and Yu Zhang, R&R at Management Science.

(Featured at 2019 MSOM SIG, 2019 Wharton EMPOM)

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. 

3. "Corporate Social Responsibility in Supply Chain: Green or Greenwashing?"

with Yilin Shi and Yu Zhang.

Perception regarding a focal firm's corporate social responsibility (CSR) depends not only on itself but also on its known suppliers. This paper provides the first empirical evidence linking CSR and supply chain information disclosure together. Specifically, it uncovers robust evidence that firms greenwash their CSR image via voluntarily disclosing environmentally responsible suppliers while concealing "bad" ones. Exogenous variations in abnormal temperatures around the world drive variations in the selective disclosure of "good" suppliers, supporting a causal interpretation of our finding. Supply chain greenwashing is more prevalent for firms who face higher competition, care more about their brand awareness, and for firms that are more profit-driven and held more by institutional investors. The greenwashing behavior mitigates after implementing mandatory CSR disclosure policies. Finally, firms who greenwash supply chains observe both sales and profitability increase, but only for the short-term.

 

4. "Inventory as a Financial Instrument: Evidence from China’s Metal Industries,"

with Vernon Hsu, major revision at Management Science.

(Featured at 2019 CSAMSE Best Paper Award)

Classical inventory theory suggests that inventory plays a vital role in matching demand and supply. This paper provides both macro and micro evidence that inventory can be used as a financial instrument to take advantage of arbitrage opportunities in financial markets with limited capital mobility. Using data from China’s country-level metal commodity imports and firm-level inventory from metal processing industries (with metal commodities as primary inputs), we show that firms can utilize the inventory of an imported product to carry lower-cost capital into a country with strict capital controls and thus gain higher financial returns. Specifically, at the country-level, we show that levels of imported metal commodities are positively associated with the expected returns from financial arbitrage. At the firm-level, we find that a higher expected return from financial arbitrage will incentivize a firm to increase its inventory level through increased short- term borrowing. In addition, firms with higher borrowing capacity, larger size, or higher sales growth are more active in using inventory as an instrument to seek higher financial gains. We also utilize a unique regulatory policy shock as a natural experiment to establish causality in our empirical analysis.

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

with Ben Charoenwong and Miaozhe Han, submitted, media at The EconomistReutersCUHK观察者网, major revision at M&SOM.

(Featured at 2020 ADBI PRN Joint Conference)

We study the impact of trade and other economic policy uncertainty on supply chain networks of American firms. The uncertainty around the trade and other economic policy contributes to supply chain risk. Whether such policy uncertainty will bring production back to the U.S. or only a redistribution of the global supply chains is theoretically ambiguous and warrants an empirical analysis. Using firm-level global supply chain data, transaction-level shipping container data, and policy uncertainty indexes, we investigate the question using reduced-form empirical specification with high dimensional fixed effects. Rather than inducing production to come “home”, on average higher U.S. trade policy uncertainty predicts an increase in foreign supplier relationships, driven by firms with majority foreign sales. In contrast, those with mostly domestic sales mildly decrease foreign supplier relationships. American firms also appear to substitute among foreign countries in response to foreign-country-specific economic policy uncertainty – shifting suppliers from countries with higher uncertainty to ones with lower uncertainty. Firms with more bargaining power respond more to all measures of economic policy uncertainty. Corporate managers should take their customers’ locations into account when making sourcing decisions; in particular, reducing operational risk due to changing economic policies may involve additional offshoring rather than re-shoring.
