ESG Performance and Firm Financial Outcomes: A Cross-Country Analysis of Developed and Emerging Markets

This study investigates the relationship between Environmental, Social, and Governance (ESG) performance and firm financial performance across a diverse cross-country sample of 2,200 firms drawn from 12 developed and 7 emerging economies over the period 2009–2022. The principal objective is to assess whether ESG engagement acts as a value-enhancing strategy, and to what extent this relationship is moderated by institutional contexts, economic development, and regulatory structures. Using a comprehensive panel dataset and addressing endogeneity through Two-Stage Least Squares (2SLS) estimation, the analysis employs multiple financial performance metrics—Return on Assets (ROA), Tobin’s Q, Return on Equity (ROE), and Operating Cash Flow to Total Assets (OCF/TA). The findings confirm a statistically significant and economically meaningful positive association between ESG performance and firm outcomes, particularly in developed markets. Disaggregated analysis reveals that environmental factors are more salient in emerging economies, while social and governance dimensions exert greater influence in developed settings. These findings provide relevant insights for managers, regulators, and investors seeking to align ESG objectives with firm performance across institutional environments.
