Inequality and Growth: A Heterogeneous Approach

Abstract

This article tests for cross-country convergence in income inequality and
 estimates its impact on growth with a heterogeneous Panel Structural Vector
 AutoRegression model, which addresses some empirical challenges plaguing
 the literature. We find that income inequality is converging across countries,
 and that its impact on growth is heterogeneous. While the median response of
 real per capita Gross Domestic Product (GDP) growth to income inequality
 shocks is negative and significant, at least one fourth of the sample presents a
 positive effect. Also, we find evidence that improved institutional frameworks
 can reduce the negative effect of income inequality on growth.
