Extreme Weather and Firm Market Value: Roles of Corporate Social Responsibility and Stock Analyst Attention

The outbreak of extreme weather events is increasing in frequency for the last decade, resulting in tremendous human and industrial losses worldwide. Evaluating and managing the effects of such events are highly urgent matters for firms, but the literature on this topic is limited. In this study, the effects of extreme weather events on the stock market performance of firms were estimated to provide a foundation for exploring how to manage such effects. From the perspective of the shareholder view, the heterogeneous effect of corporate social responsibility (CSR) on stock performance associated with extreme weather events were examined. Data on natural disasters that were caused by six types of extreme weather and occurred between 2001 and 2021 in China were used to construct a database of 2,718 Chinese listed manufacturing firms and 23,529 observations regarding the potential effects by extreme weather events. An event analysis indicated that the extreme weather events bring an average of 0.97% drop in the stock performance of potentially affected firms for the month that the event starts and the next month. A subsequent cross-sectional analysis revealed that a high CSR level is associated with low market value during extreme weather events, while a high level of stock analyst attention alleviates the negative effect of CSR on the stock performance of extreme weather events. This study enriches the existing literature and offers practical insights for managers in the fields of CSR and operations management, highlighting the complex dynamics between CSR activities, analyst attention, and stock market performance during extreme weather events.
