DOES EDUCATION REDUCE INCOME INEQUALITY? A META‐REGRESSION ANALYSIS
通过元回归分析大量实证文献，发现教育能减少高收入者份额、增加低收入者份额，尤其在非洲效果显著；中学教育效果可能强于小学，但结论不稳健。
Abstract This paper reexamines the effects of education on inequality through a comprehensive meta‐regression analysis of the extant empirical literature. We find that education affects the two tails of the distribution of income: Education reduces the income share of top earners and increases the share of the bottom earners. Education has been particularly effective in reducing inequality in Africa. Some of the results suggest that secondary schooling appears to have a stronger effect than primary schooling, though this finding is not always robust. The heterogeneity in reported estimates can be largely explained by differences in the specification of the econometric model and measure of inequality and education.
