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.

with Senay Agca, Volodymyr Babich, and John R. Birge, major revision at Management Science, available at SSRN, 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 Bullwhip Effect in Supply Networks,"

We offer a new network perspective on one of the central topics in OM - the bullwhip effect (BWE). We start with a puzzling observation: while the traditional intra-firm measure of the BWE increases at upstream layers of the network, the demand variability experienced by upstream firms does not increase commensurably. To reconcile these two facts, we hypothesize that firms manage their customer base to smooth out the aggregate demand. We provide evidence that buyer-supplier relationship formation or dissolution is associated with smoothing of the aggregate demand experienced by suppliers. This provides fresh insight into how firms may leverage their buyer-supplier relationships to mitigate the impact of the BWE.

 

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

with Jie Peng and Yu Zhang, available at SSRN.

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, submitted to Management Science, available at SSRN.

(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.
