The nonlinear road to happiness: Making sense of ESGD impacts on well-being

This study examines the heterogeneous impact of environmental, social, governance, and digital (ESGD) factors on subjective well-being across 86 countries from 2005 to 2019, using Method of Moments Quantile Regression. The results reveal complex, nonlinear relationships between ESGD factors and well-being. CO2 emissions display an inverted U-curve, suggesting eventual negative impacts after initial gains. Our findings suggest that renewable energy only benefits higher quantiles, revealing affordability issues. Social and governance factors like labor participation and women's political participation relate nonlinearly to well-being across income levels, reflecting employment quality and social norms differences. Similarly, digital factors improve well-being in high-income countries but not lower-middle-income nations, due to economic complexity gaps and the digital divide. A “digital economy paradox” emerges where more digital skills combined with limited digital economies decrease well-being in lower-middle income countries signifying the need for tailored digital policies. This study enhances understanding of links between ESGD factors and well-being patterns.
