National wealth, cultural moderators and pollution mortality : a panel analysis of 170 countries

Global concerns have arisen due to pollution-related mortality, and scholars studying the Environmental Kuznets Curve (EKC) have explored the impact of economic growth on carbon emissions, yielding conflicting findings. Considering these opposing perspectives on whether wealth exacerbates or mitigates the negative consequences of environmental pollution, we aim to assess the influence of economic growth on pollution-related mortality and investigate whether national culture moderates its impact. To gain insights into the effects of economic growth on pollution-related mortality, we utilized panel data covering 170 countries over a span of 23 years (1996-2017). Initially, we examined the relationship between GDP per capita and pollution-related mortality, finding support for the theory of a curvilinear correlation but not for the concept of a bell-shaped curve. Upon introducing cultural moderators, the curve shifts in different directions along various dimensions. High power distance and masculinity cultures are associated with increased pollution-related mortality, whereas individualist and long-term orientation cultures are linked to reduced pollution-related mortality. The directions of these moderators align with both linear and nonlinear analyses, except for uncertainty avoidance. This study makes significant contributions to the critical issue of pollution-related mortality, extending beyond traditional sustainability analyses. Additionally, it provides a robust examination of the intertwining of economic wealth and culture, challenging the dominance of either type of logic. Lastly, our study draws attention to policy-driven solutions.
