Managerial ability and voluntary ESG disclosure and assurance: evidence from Taiwan

PurposeThe purpose of this study is to explore the effect of managerial ability on voluntary environmental, social and governance (ESG) disclosure and assurance. By focusing on managerial ability, this study provides a more nuanced understanding of the factors influencing a firm's ESG disclosure and assurance practices. This study contributes to a relatively unexplored area of study regarding the role of top management in promoting ESG reporting.Design/methodology/approachThis study draws on a sample of publicly listed firms from 2014 to 2019 in Taiwan and applies the data envelopment analysis method to measure managerial ability. Heckman's (1979) two-step model is used to estimate the primary models to prevent the results from being affected by possible bias because of self-selection.FindingsThe empirical evidence suggests that managerial ability is positively related to voluntary ESG disclosure and intention to seek third-party assurance of the report. Overall, managerial ability determines whether a firm will use voluntary ESG disclosure and assurance as a corporate strategy to respond effectively to stakeholders' needs. The findings are robust after using alternative measures of managerial ability.Practical implicationsInvestors and other stakeholders keen on seeking ESG information offered by companies could find the findings of this study valuable. By better comprehending how managerial competence impacts voluntary ESG disclosure and assurance, stakeholders may be better equipped to hold companies responsible for their ESG disclosure practices and make informed investment decisions.Social implicationsIn the ESG decision-making process, managers with better abilities have a higher tendency to use voluntary disclosure and assurance as a part of the company's sustainable policy.Originality/valueUnlike previous studies of the determinant factors of ESG disclosure, which mainly explore factors at the national or corporate level, this study focuses on factors at the individual level (i.e. managerial ability) to fill the gap in the literature. This study also presents empirical evidence that corroborates the idea that managerial competence can influence not only ESG disclosure but also the voluntary assurance of ESG information.
