摘要:This paper examines how the level of institutional ownership affects environmental, social, and governance (ESG) performance in emerging countries by jointly investigating a nonlinear relationship. By examining an international sample composed of 17,318 firm–year observations from the period 2012–18 for 16 emerging countries, our findings reveal that the ESG performance of firms located in emerging countries depends on the level of influential institutional ownership, and displays a U-shaped relation, particularly for environmental disclosure. Institutional investors with low ownership are less likely to promote higher ESG performance in emerging countries, although this effect is attenuated when institutional ownership reaches a significant percentage, constituting a critical mass.
