人力资本与迁移：一个警示性案例
- 研究问题
- 当迁移者在目的地的教育回报低于原籍时，放松迁移限制如何影响教育积累，教育补贴又能在多大程度上抵消影响？
- 方法与思路
- 作者结合中国家庭收入项目面板、1983 年改革的双重差分设计，以及含认知和非认知技能异质性的生命周期动态离散选择模型。
- 材料陈述的贡献
- 摘要报告农村人群受教育年限减少 0.4 年，并称结构模型能复现双重差分估计；补贴模拟显示部分抵消与完全抵消的成本不同。
- 阅读关注点
- 应核对改革比较组和趋势证据、城乡教育回报测量、动态模型识别，以及补贴反事实对技能分布和行为设定的依赖。
- 阅读边界
- 仅据所给 RePEc 出版社摘要，不推断刊本变化。摘要未说明双重差分识别条件、结构估计细节及不确定性，补贴结论依赖模型设定。
原文摘要
We analyze the impact that the option of migration might have on human capital accumulation. We show that, when the return to education for migrants is lower in the destination than in the origin, the overall incentive to accumulate human capital is reduced as restrictions on migration are relaxed. We use panel data from the Chinese Household Income Project to document that the return to education for rural individuals is lower in urban areas than in rural areas. We then use a difference-in-differences design to show that the 1983 reform that eliminated the strong restriction that existed for rural–urban migration resulted in a reduction of 0.4 years of schooling for rural people in China. Guided by these results, we estimate a life-cycle dynamic discrete choice model of education decisions and circular rural–urban migration in which individuals differ in observable characteristics and unobservable cognitive and non-cognitive skills. We validate the model by showing it is able to replicate the impact estimates from the difference-in-differences specification. Our simulations show that, while it would take a small subsidy (conditional on staying in school) to undo about 40% of the negative effects of the 1983 policy on rural education, the annual subsidy would need to be half of annual earnings to undo the effects entirely.
