| Abstract |
The ESG (environmental, social, and governance) practice has become very important in contemporary business, and it is believed to have a significant impact on firm value. However, how investors react to firms' ESG performance is still unknown. Exploiting user-generated content from a popular online investment community (Seeking Alpha) and ESG performance scores from a professional database (Sustainalytics), we first run a fixed-effect panel regression and find an overall positive relationship between ESG and investor attention but no relationship between ESG and investor sentiment. We then conduct an event-study analysis, in which we classify changes in ESG performance as upgrade and downgrade events and find that the significant relationship between ESG and investor attention holds for the downgrade events but not for the upgrade events. We also conduct various robustness checks, on both ESG and investor attention, to rule out potential effects of other factors, such as firm size, debt, intangible assets, and profitability. Our further mechanism analysis reveals that the effect of ESG on investor attention is driven by the social and governance factors rather than the environmental factors. Our work makes both theoretical and practical contributions by identifying the nuanced effect of ESG on investors' reactions in the social media era. |
