Estrutura de propriedade, divulgação social, ambiental e de governança, e assimetria de informação: o caso brasileiro

This research aimed to analyze the moderating effects of ownership structure on the relationship between environmental, social, and governance (ESG) disclosure and information asymmetry in Brazilian companies. A quantitative, descriptive, and documentary study was conducted with data from 68 companies listed on the Bolsa Brasil Balcão (B3) between 2015 and 2022, tested using the one-step GMM dynamic panel system. The main findings indicate that ESG disclosure can reduce information asymmetry, while ownership concentration and institutional ownership have a positive moderating effect on this relationship. The study emphasizes the need for regulatory actions to address potential issues faced by less informed investors and improve the disclosure of ESG practices.
