Development outcomes, resource abundance, and the transmission through inequality

The paper studies the effect of resource abundance on human development in light of two complementary hypotheses: (i) resource abundance increases the inequality of income distribution within a country and (ii) higher income inequality reduces human development. The estimation of a system of equations provides support to both hypotheses. In addition, results suggest that resource abundance might also affect human development by reducing the quality of institutions. However, while statistically significant, this effect is quantitatively small. Finally, there is evidence of a strong, negative direct effect of resource abundance on human development after controlling for inequality, institutional quality, and the level of per-capita income.
