A Reassessment of the Relationship Between Inequality and Growth
使用改进的收入不平等数据集，通过面板估计控制国家特定效应，发现收入不平等在短期和中期对经济增长有显著正向影响，且结果稳健。
This paper challenges the current belief that income inequality has a negative relationship with economic growth. It uses an improved data set on income inequality which not only reduces measurement error, but also allows estimation via a panel technique. Panel estimation makes it possible to control for time-invariant country-specific effects, therefore eliminating a potential source of omitted-variable bias. Results suggest that in the short and medium term, an increase in a country's level of income inequality has a significant positive relationship with subsequent economic growth. This relationship is highly robust across samples, variable definitions, and model specifications.
