ESG and volatility risk: International evidence

摘要

Abstract This study examines the volatility risk for firms that are rated high on environmental, social, and governance (ESG) dimensions in emerging markets and developed markets outside the United States and Canada. Employing the Morgan Stanley Capital International (MSCI) ESG Leader indices, this study investigates the impact of good news and bad news on the volatility risk for the highest ESG‐rated firms through multivariate DCC‐EGARCH modeling. This study finds that the impact of a negative news shock of size 2 standard deviations is approximately 45 higher than that of a positive news shock of the same size for the case of the developed markets under interest. With respect to emerging markets, this study reports that the impact of a negative news shock of size 2 standard deviations is 41 higher than that of a positive news shock of the same size. The results provide empirical evidence in support of the hypothesis that the volatility impact of news for high ESG‐rated firms in developed markets and emerging markets is larger for bad news compared to good news, and the results are robust across time. The empirical findings underline the importance of reporting‐related disclosures of ESG initiatives, and provide seminal evidence of a slow response to news by high ESG‐rated firms in emerging markets.
