We examine whether and how common ownership affects Environmental, Social, and Governance (ESG) ratings—an important research question given the increasing use of these ratings in investment decisions and corporate evaluations. We find that companies with major shareholders in common with the rating agency (“sister firms”) tend to receive higher ESG ratings. When a company becomes a sister firm through a change in the rating agency's ownership structure, its rating from that agency is subsequently upgraded, whereas its ESG ratings from other agencies remain unchanged. Sister firms exhibit greater rating disagreements across agencies than other firms. The higher ESG ratings for sister firms are partly attributable to the transfer of immaterial positive ESG information through common owners. The common ownership effect is more pronounced when the owner can exert a greater influence on the rating agency. Moreover, sister firms with initially elevated ratings demonstrate poorer future ESG performance. Overall, our findings suggest that owners can affect ESG ratings of their portfolio companies in a way consistent with their influence and interest

We examine whether and, if so, how retail consumers change their shopping in response to firm‐specific negative environmental, social, and governance (ESG) news. Using an event study methodology, we do not find significant changes in consumer foot traffic in response to negative ESG news, on average. However, the average consumer reacts negatively when such news is covered by national or global media outlets, which elevates consumer awareness. In addition, we provide evidence of the heterogeneity in responses to negative ESG news across consumer groups. Consumers in more ESG‐conscious counties, as measured by county ESG preferences, income, education, and political ideology, reduce store visits in response to negative ESG news. In contrast, consumers in the least ESG‐conscious counties increase their visits in response to negative ESG news. These opposing reactions explain the insignificant average consumer response to negative ESG news. Furthermore, the ESG‐conscious consumers' negative reaction is, at most, modest, dissipating within six weeks. Overall, our findings suggest that firms face divergent responses to ESG activities from different consumer groups, underscoring the divisive nature of ESG issues
