This paper, “ESG: A Panacea for Market Power?” by Philip Bond and Doron Levit (2024), examines how firms’ social (“S”) ESG policies affect market competition. It finds that moderate ESG actions such as fairer treatment of workers or customers can reduce market power and improve welfare, while overly aggressive policies harm both firms and stakeholders. The authors show that competition in ESG policies among socially minded firms can deliver efficient, welfare-maximising outcomes, linking ESG adoption to market structure, corporate governance models, and executive incentives.
