Does Carbon Risk Influence Stock Price Crash Risk?

Authors: Bose, S., Edwin, L., Minnick, K., Schorno, P., & Shams, S.

In this study, we examine whether carbon risk matters in acquisitions. Using a firm's carbon emissions to proxy for carbon risk, we examine whether an acquirer's level of carbon emissions is related to the decision to engage in acquisitions and achieve subsequent acquisition returns. The results show that firms with higher emissions have an increased likelihood of acquiring foreign targets while, at the same time, having a decreased likelihood of acquiring domestic targets. Acquirers with large carbon footprints seek out targets in foreign countries that have low gross domestic product (GDP) or weak environmental, regulatory, or governance standards. We also examine the relationship between carbon emissions and announcement returns. We find that cross-border acquisition announcement returns are higher when acquirers with high carbon emissions acquire targets in countries with fewer regulations or weaker environmental standards. Focusing on the interplay of corporate social responsibility (CSR) and carbon emissions, we find that investors censure acquirers that promote CSR while also having high carbon emissions, thus resulting in worse abnormal returns. This is particularly the case if the target country is wealthy or has stronger country governance or strong environmental protection. Our findings add insight on the channels through which a focus on reducing carbon risk can add value for shareholders.

Does Customer Focus Influence Firms' Climate-Change Reporting Decisions? The Role of Market-Driven Corporate Culture.

Authors: Bose, S., Cahan, S., Dhole, S., & Mishra, S.

While there is increasing investor demand for climate-change disclosures, less is known about how a firm's culture influences its decision to provide these disclosures. In this study, we focus on market-driven or customer-focused culture. We expect that firms with a market-driven culture (MDC) will be more likely to provide climate-change disclosures because such firms are more customer-oriented. Our results are consistent with this expectation. We also find that the level of carbon emissions is negatively associated with MDC, suggesting that the climate-change disclosures are not merely greenwash. Further, we find firm value is higher for MDC firms that provide climate-change disclosures. Overall, we contribute to the literature by identifying MDC as an important determinant of climate-change disclosure.

Does Commitment to Operational Sustainability Pay Off? International Evidence.

Authors: Saha, A., Bose, S., & Lobo, G.

This study examines the relationship between operational sustainability expenditure and firm value using a sample of firms from 38 countries. We find that operational sustainability expenditure is positively associated with firm value. This finding suggests that investors positively evaluate firm-level expenditure on operational sustainability activities. We also document that the presence of a sustainability committee, stakeholder engagement and eco-innovation, and the inclusion of sustainability-related targets in compensation contracts of Chief Executive Officers (CEOs) positively moderate the association between operational sustainability expenditure and firm value. Additionally, country-level factors, such as strong governance, a stakeholder-oriented business culture and investor protection, as well as firms that operate in environmentally sensitive industries further enhance this relationship. These findings have important implications for regulators, policymakers, investors and other stakeholders, highlighting the value of strategic operational sustainability expenditure. Specifically, regulators can use these findings to better understand the importance of adopting tangible and monetary measures when evaluating firms� commitment to operational sustainability.
