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.

This paper provides evidence that the formation of global supply chain partnerships increases access to cross-border financing. The findings are detected in all three major financing markets - equities, syndicated loans, and public debt. Difference-in-differences and instrumental variable tests allow us to draw causal inferences from our results. We propose that our findings reflect the factor of informational visibility where less visible firms can overcome informational obstacles to cross-border financing by establishing global supply chains. Specifically, we provide evidence that firms that are small, held less by institutional investors, and followed by fewer analysts have more benefit in cross-border financing from the formation of the global supply chain. Our findings have important implications for firms attempting to integrate into the global supply-chain network. More broadly, our findings suggest that the information generated by operational activities can have important effects on subsequent financing activities.

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.

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.

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.
