The Limits of Local Laws in Global Supply Chains: Extending Governance or Cutting Ties?

Abstract
We exploit an information shock related to the German Supply Chain Due Diligence Act and use detailed customs data to analyze how smaller, non-listed firms respond when expecting accountability for externalities beyond their organizational boundaries. Product-level regressions reveal a substantial reduction in imports from high ESG-risk production sectors. Adjustments occur mainly at the extensive margin, indicating that firms cut ties with high-risk suppliers. The product-level results translate into meaningful changes in overall international procurement for firms with Big Four auditors. Our findings suggest potential limits to mandates requiring firms to integrate broad sustainability considerations into operational decisions.

Understanding CSR Champions: A Machine Learning Approach
Alona Bilokha, Mingying Cheng, Mengchuan Fu, Iftekhar Hasan
Annals of Operations Research,

2025
Abstract
In this paper, we study champions of corporate social responsibility (CSR) performance among the U.S. publicly traded firms and their common characteristics by utilizing machine learning algorithms to identify predictors of firms’ CSR activity. We contribute to the CSR and leadership determinants literature by introducing the first comprehensive framework for analyzing the factors associated with corporate engagement with socially responsible behaviors by grouping all relevant predictors into four broad categories: corporate governance, managerial incentives, leadership, and firm characteristics. We find that strong corporate governance characteristics, as manifested in board member heterogeneity and managerial incentives, are the top predictors of CSR performance. Our results suggest policy implications for providing incentives and fostering characteristics conducive to firms “doing good.”

The Corporate Investment Benefits of Mutual Fund Dual Holdings
Rex Wang Renjie, Patrick Verwijmeren, Shuo Xia
Journal of Financial and Quantitative Analysis,
Nr. 2,
2025
Abstract
Mutual fund families increasingly hold bonds and stocks from the same firm. We present evidence that dual ownership allows firms to increase valuable investments and refinance by issuing bonds with lower yields and fewer restrictive covenants, especially when firms face financial distress. Dual holders also prevent overinvestment by firms with entrenched managers. Overall, our results suggest that mutual fund families internalize the agency conflicts of their portfolio companies, highlighting the positive governance externalities of intra-family cooperation.

Banker Directors on Board and Corporate Tax Avoidance
Wenjie Ding, Iftekhar Hasan, Qian Song, Qingwei Wang
Journal of Empirical Finance,

Abstract
We investigate how shareholder-debtholder conflict of interest affects the corporate tax avoidance using a unique setting of the affiliated and unaffiliated commercial bankers’ board representation. Consistent with the notion that board representation grants lenders’ access to private information that helps monitor and influence firms’ tax practice, we find that appointments of affiliated banker directors significantly reduce firms’ tax avoidance behavior, while appointing unaffiliated banker directors shows no such effect. The impact of affiliated banker directors on alleviating tax avoidance is stronger among firms with severer conflict of interest between shareholders and debtholders, specifically among firms with weaker corporate governance, higher financial leverage and higher CEO stock ownership.

A Belowground Perspective on the Nexus between Biodiversity Change, Climate Change, and Human Well-being
Michael Koetter, et al.
Journal of Sustainable Agriculture and Environment,
Nr. 2,
2024
Abstract
Soil is central to the complex interplay among biodiversity, climate, and society. This paper examines the interconnectedness of soil biodiversity, climate change, and societal impacts, emphasizing the urgent need for integrated solutions. Human-induced biodiversity loss and climate change intensify environmental degradation, threatening human well-being. Soils, rich in biodiversity and vital for ecosystem function regulation, are highly vulnerable to these pressures, affecting nutrient cycling, soil fertility, and resilience. Soil also crucially regulates climate, influencing energy, water cycles, and carbon storage. Yet, climate change poses significant challenges to soil health and carbon dynamics, amplifying global warming. Integrated approaches are essential, including sustainable land management, policy interventions, technological innovations, and societal engagement. Practices like agroforestry and organic farming improve soil health and mitigate climate impacts. Effective policies and governance are crucial for promoting sustainable practices and soil conservation. Recent technologies aid in monitoring soil biodiversity and implementing sustainable land management. Societal engagement, through education and collective action, is vital for environmental stewardship. By prioritizing interdisciplinary research and addressing key frontiers, scientists can advance understanding of the soil biodiversity–climate change–society nexus, informing strategies for environmental sustainability and social equity.

The Bright Side of Bank Lobbying: Evidence from the Corporate Loan Market
Manthos D. Delis, Iftekhar Hasan, Thomas Y. To, Eliza Wu
Journal of Corporate Finance,

2024
Abstract
Bank lobbying has a bitter taste in most forums, ringing the bell of preferential treatment of big banks from governments and regulators. Using corporate loan facilities and hand-matched information on bank lobbying from 1999 to 2017, we show that lobbying banks increase their borrowers' overall performance. This positive effect is stronger for opaque and credit-constrained borrowers, when the lobbying lender possesses valuable information on the borrower, and for borrowers with strong corporate governance. Our findings are consistent with the theory positing that lobbying can provide access to valuable lender-borrower information, resulting in improved efficiency in large firms' corporate financing.
