一般均衡中的大规模教育改革:来自印度的断点回归证据

Large-Scale Education Reform in General Equilibrium: Regression Discontinuity Evidence from India
Journal of Political Economy · 2022 · Gaurav Khanna

中文摘要

政府对教育进行大规模投资所产生的经济后果,取决于劳动力市场和教育部门的一般均衡效应。我构建了一个一般均衡模型,用以刻画覆盖全国的大规模学校教育计划所带来的后果。利用源自印度政府政策的断点回归,我对模型中的弹性进行了无偏估计。一年教育带来的收入回报率为13.4%,而一般均衡下的劳动力市场效应将这一回报率大幅压低了6.6个百分点。这些一般均衡效应对不同队列和技能群体产生了分配后果:非熟练工人的境况改善,而熟练工人的境况恶化。

Abstract

The economic consequences of large-scale government investments in education depend on general equilibrium effects in both the labor market and the education sector. I develop a general equilibrium model capturing the consequences of massive countrywide schooling initiatives. I provide unbiased estimates of the model’s elasticities, using a regression discontinuity derived from Indian government policy. The earnings returns to a year of education are 13.4%, and the general equilibrium labor market effects substantially depress returns, by 6.6 percentage points. These general equilibrium effects have distributional consequences across cohorts and skill groups, whereby unskilled workers are better off and skilled workers worse off.
