PurposeThe study is aimed at examining the impact of ESG on the financial performance (FP) of firms and determining the difference between the impact of ESG on market-oriented financial performance measure (Tobin’s Q) and internal productivity-based financial measure (ROA). The study has also explored the influence of managerial ability and institutional quality as moderating variables on the relation between ESG and the financial performance of firms (both measures of FP: Tobin’s Q and ROA).Design/methodology/approachThe study is quantitative exploratory and uses panel data of 687 publicly listed companies from the year 2013–2023. Data has been acquired from the reputed data providers and OLS regression has been used for panel data analysis with fixed effects.FindingsThe study reaffirms the positive impact of ESG on the financial performance of firms. Each pillar of ESG (environmental, social, and governance) has been found positively related to both measures of financial performance (Tobin’s Q and ROA). The study reveals that managerial ability and institutional quality, acting as supplementary variables, moderate the relationship between ESG and financial performance of firms.Research limitations/implicationsA limited sample comprising data from only 687 firms was used for the analysis. The latest data was not available, therefore, data from 2013 to 2023 was used in the study.Practical implicationsThis study indicates that ESG practices, which are mostly discretionary in Emerging Economies, can be induced through institutional pressures and ensuring higher quality managers. Policymakers in government institutions have to determine the inefficiencies, corrupt practices, and inconsistencies in policies that lower the effectiveness of institutions making them business-unfriendly. At the organizational level, policymakers need to ensure that responsible positions in the organization are held by managers with higher managerial ability. It is also to be ensured by shareholders that managers do not over-invest in ESG-related projects, particularly in organizations with weaker financial status. For managers, it is important to understand the positive benefits associated with ESG, even though they are in the long term.Social implicationsIn Emerging Economies, the official monitoring and regulatory mechanisms are weak, and lack a supportive attitude toward ESG initiatives. Voluntary and proactive firm-level environmental and social initiatives need to be encouraged and rewarded by institutions with public acknowledgment. ESG should be given priority by organizations for improving the quality of services and better social impact of businesses on society.Originality/valueMost of the past research explored the impact of ESG on financial performance in advanced countries or in emerging markets in a single/limited number of countries or industries. Also, past studies investigated the impact of institutional quality and managerial ability on ESG/financial performance in separate models. Conversely, this study has used a multi-country and multi-industry sample for more generalizable findings. Against the backdrop of the institutional environment of Emerging Economies, the study extends Institutional Theory and Upper Echelon Theory to include the role of managerial ability and institutional quality in the relationship between ESG and firms’ financial performance.
