Supply chain management played a central role during the COVID-19 crisis, as the outbreak of the pandemic disrupted the majority of all global supply chains. This paper tests whether companies that use green supply chain management (GSCM) practices benefited from a buffer effect in the context of COVID-19. Our empirical analysis, conducted on a sample of U.S. companies, shows that GSCM companies experienced less negative abnormal stock returns during the crisis. This result contributes to the literature on financial impact of GSCM, finding that GSCM is perceived as an effective risk management tool and can serve as an effective drug against COVID-19 crisis. Our paper also contributes to the business debate on the role of green supply chains in the post-COVID19 world.

Purpose Integrated reporting (IR) provides integrated financial and nonfinancial information about companies based on the integrated thinking principle. This study aims to investigate how the cost of equity relates to IR disclosure and the impact of an effective legal system on this relationship. Effective legal system (“enforcement”) represents the strength of the legal system of a country. Although voluntary initiatives are essentially not based on regulations, the authors expect that the effective legal system will influence the implementation of such. Design/methodology/approach To test the study’s hypotheses, linear regressions were applied using the Thomson Reuters database to analyze 20,463 firm-year observations between 2010 and 2017. The treatment group comprised companies that adopted IR; using propensity score matching, the authors defined the control group. The authors adopted a research design based on difference-in-differences to compare the cost of the capital of treatment with the control group for the periods before and after the IR adoption. Findings The results indicate that IR disclosure is negatively related to the cost of equity, and this negative effect is more prevalent for companies operating in high-enforcement environments. Research limitations/implications Cost of equity is not a directly observable variable, implying that the results are sensitive to changes in the parameters that are used to compute this term. The results can help companies looking for evidence of potential effective gains of adopting IR. They also help understand that discussions related to environment, social, and governance information are somehow incorporated by analysts and investors, and reflected in the cost of raising funds. Originality/value This study demonstrates how IR relates to the cost of equity considering a global sample of voluntary adopters. It also analyzes the impact of institutional factors on this relationship by using a robust method of analysis. The results support the argument that companies in a strong legal system are more likely to behave sustainably and to disclose this attitude. Additionally, they are pressured to implement proposals rather than just adopting an initiative as a label.

Corporate short-termism is arguably one of the main causes of economic, social, and environmental unsustainability. This paper studies the effectiveness of loyalty shares-shares granting extra dividends or voting rights to shareholders holding them for a specified period of time-in limiting short-termism. Although there are arguments both supporting (antidote view) and opposing (poison view) loyalty shares' effectiveness, empirical evidence on the theme is scant. By employing earnings management as a proxy for corporate short-termism and by relying on a hand-collected database of Italian firms, we find that loyalty shares can serve as an effective antidote against short-termism. This study contributes to academic literature on corporate governance and accounting and informs the debate among policymakers on loyalty shares' effectiveness.
