Educational human capital and levels of income: Evidence from states in India, 1965 – 92
研究了1965-1992年印度15个主要邦的教育人力资本（以高中入学率衡量）与稳态收入水平之间的长期关系，发现教育对收入有稳健正向影响，且性别教育差距越大的邦稳态收入越低。
Abstract This paper examines the long-run (steady-state) relationship between levels of educational human capital and levels of income for the 15 major states of India between 1965 and 1992. The relationship is estimated using the Pooled Mean Groups (PMG) technique; which produces common long-run coefficients but allows heterogeneity of the short-run adjustment parameters. The results suggest that levels of educational human capital, proxied by high school enrollment rates, have a robust positive impact on steady-state levels of income. This is true for male and female education, and the regressions also suggest that states which have larger gender-gaps in education have lower steady-state incomes. The estimated relationship is robust to the inclusion of alternative measures, added controls, and variation in the degree of state coverage.
