Résumé
This paper investigates the impact of corporate social responsibility (CSR) on shareholders' wealth during market downturn, focusing on the market crash caused by the COVID-19 pandemic and its aftermaths. We evaluate the relationship between firms' CSR and stock returns using a sample of 803 firms listed on the Korean stock market. The results of our study reveal that firms' pre-crisis CSR activities do not protect shareholders' wealth during the crisis;in fact, they negatively affected stock returns during the COVID-19 crisis. This finding is consistent across several robustness tests and challenges the prevailing notion that CSR is solely a philanthropic endeavor. This study suggests that firms need to reconsider their CSR approach in order to better align it with shareholders' interest.
