ESG Shocks in Global Supply Chains

Review of Financial Studies 2026
Abstract We show that U.S. firms cut imports by 31.8% when their international suppliers experience environmental and social (E&S) incidents. These trade cuts are larger for publicly listed U.S. importers facing high E&S investor pressure and lead to cross-country supplier reallocation, suggesting that E&S preferences in capital markets can be privately costly but have real effects for foreign suppliers. Larger trade cuts around the incident result in better supplier E&S performance in subsequent years and in the eventual resumption of trade. Our results highlight the role of investors in ensuring suppliers’ E&S compliance along global supply chains.

The Real Effects of Mandatory Nonfinancial Disclosure: Evidence from Supply Chain Transparency

The Accounting Review 2022 97(5), 399-425
ABSTRACT This paper studies whether and how mandatory nonfinancial disclosure affects firms' real decisions. I exploit a disclosure regulation enacted in California, which mandates that firms disclose how they conduct due diligence to address their suppliers' human rights abuses. I find that treated firms increase their supply chain due diligence, and their suppliers' human rights performance improves following the regulation. The effects are stronger when firms face greater pressure from non-governmental organizations (NGOs) and socially conscious shareholders, when customers have greater incentives to use the newly disclosed information, and when the regulation leads to a larger increase in information comparability. Collectively, the results suggest that mandatory nonfinancial disclosure can affect firms' real decisions through market mechanisms and that stakeholder responses play a key role.

Shareholder value implications of supply chain ESG: evidence from negative incidents

Review of Accounting Studies 2025 30(3), 2185-2217 open access
Using a novel measure that captures negative ESG incidents at both listed and private suppliers, we provide large-scale evidence on the value implications of supply chain ESG. We find that firms with fewer supply chain ESG incidents exhibit higher future accounting performance and that this effect is stronger in the presence of more conscious customers and vulnerable supply chains. We also find that firms with robust supply chain ESG exhibit higher future stock returns and that this effect is more pronounced when information frictions are higher, which suggests that it takes time for the market to understand the value implications of supply chain ESG. Overall, we highlight the benefits of managing supply chain ESG and the decision usefulness of the related information.

Corporate Disclosure as a Tacit Coordination Mechanism: Evidence from Cartel Enforcement Regulations

Journal of Accounting Research 2020 58(2), 295-332
ABSTRACT We empirically study how collusion in product markets affects firms' financial disclosure strategies. We find that after a rise in cartel enforcement, U.S. firms start sharing more detailed information in their financial disclosure about their customers, contracts, and products. This new information potentially benefits peers by helping to tacitly coordinate actions in product markets. Indeed, changes in disclosure are associated with higher future profitability. Our results highlight the potential conflict between securities and antitrust regulations.

Mandatory Information Exchange, Cross-Border Income Shifting, and the Physical Flow of Tangible Goods

The Accounting Review 2026 101(4), 169-201 open access
ABSTRACT We examine whether mandatory tax information exchange agreements between governments have real effects on firms’ physical trade in tangible goods. We posit that some of the physical trade in tangible goods flowing through low-tax jurisdictions is intended to facilitate income shifting. As such, shocks to enforcement via mandatory information exchange agreements could cause firms to change the physical flow of goods. Using firm-level shipping container data, we find that adoption of bilateral tax information exchange agreements (TIEAs) between the U.S. and foreign jurisdictions is associated with significant decreases in the volume of imports by U.S. firms from those jurisdictions. We also find reallocation effects: U.S. firms increase imports from jurisdictions in the same subregion as the treated jurisdiction, resulting in minimal overall change in total imports. To our knowledge, ours is the first study to document a connection among enforcement-related tax disclosure, income shifting, and physical trade flows. Data Availability: The data used in this study are available from the sources cited in the paper. JEL Classifications: F14; F18; F23; H25; H26.

How government procurement shapes corporate climate disclosures, commitments, and actions

Review of Accounting Studies 2025 30(2), 1968-2014 open access
Abstract This study examines how government procurement impacts firms’ environmental disclosures and whether they have tangible effects. Using a triple-difference research design that exploits the exogenous increase in federal funding allocations to counties based on population census revisions, we find that firms with high exposure to government contracts significantly increase climate disclosure following expanded procurement opportunities. We also document that enhanced disclosure is characterized by a positive tone that emphasizes firms’ green investment and commitment to climate adaptation. The effect is more pronounced in counties with a greater increase in procurement volume and when firms have lower ex ante sustainability performance. Finally, we find firms that increase climate disclosure are more likely to earn government contracts, and they undertake real actions by reducing toxic emissions and enhancing the development of green products. Overall our results suggest government procurement promotes corporate climate responsibility by incentivizing firms to undertake climate mitigation actions.

Learning from peers: Evidence from disclosure of consumer complaints

Journal of Accounting and Economics 2024 77(2-3), 101620
In 2013, the U.S. Consumer Financial Protection Bureau released a database of consumer complaints filed against banks under its supervision (“CFPB banks”). We find that after the disclosure, rival banks exhibit a greater increase in mortgage approval rates in markets with more intensive mortgage complaints about CFPB banks. The effect is weaker when rivals have more expertise in the local market, are less concerned about credit risk due to mortgage sales, and locate in areas with more alternative information about the CFPB banks. The effect is concentrated in severe complaints and complaints related to loan underwriting practices. In addition to approving more loans, rivals also open more branches and are more likely to post a job opening in these markets. The findings suggest that these banks learn from the nonfinancial disclosures about operational deficiencies of peers (i.e., CFPB banks) in local markets, which alleviates their adverse selection concern about expanding.

Contract contingencies and uncertainty: Evidence from product market contracts

Journal of Accounting and Economics 2025 79(2-3), 101743
We study contingencies written in firms' material product market contracts, focusing on the theoretical prediction of uncertainty as an important determinant. We identify contract contingencies from firms’ public regulatory filings and examine the effects of general business uncertainty and specific innovation-related uncertainty. To enhance causal inference, we utilize two major business shocks (i.e., the 2008 Financial Crisis and the COVID pandemic) and the diffusion of 29 disruptive innovation shocks (Bloom et al., 2021). We also explore the effects of re-negotiation costs and writing costs. Overall, our empirical results are consistent with predictions from dynamic models of incomplete contracting.
