Abstract

To mitigate risk, should companies signal a broad range of environmental, social, and governance initiatives or instead focus on only a few ESG issues? Drawing on signaling theory, we propose that a broad array of ESG initiatives generates not only signal consistency but also accelerating signal costs. Our empirical results support the resultant hypothesis of a curvilinear relationship between ESG scope and equity risk. In addition, this U-shaped curve seems to become steeper when firms face multiple media-reported ESG controversies. Overall, our study qualifies the conventional wisdom that firms can reduce equity risk by attending to a wide variety of stakeholders and highlights the moderating impact of the firm’s media environment.
