Randomized analysis confirms environmental-dominance inequality in income and health measures, indicating significant disparities.
Key Points
This research aims to confirm the environmental-dominance inequality by analyzing variance in economic indicators across different aggregation levels.
Computed Var(ln rho_eff) using three public datasets: Opportunity Atlas, World Bank GDP per capita PPP, and World Inequality Database.
Analyzed data across four levels of aggregation: U.S. census tracts, between countries, within-country deciles, and global pooled individuals.
Performed a partial-identification analysis to evaluate the robustness of the dominance ratio R under varying conditions.
Dominance ratio R ranged between 27 and 134 at the global level with an aggregate value of 4.33.
The hypothesis was supported globally and across country levels but weakened within homogenized units, indicating the inequality is outcome-dependent.
A time-series analysis from 1990-2022 showed stable aggregate R while revealing shifts from between-country to within-country dispersion, aligning with Piketty's r > g dynamics.
