Intergenerational Mobility and Unequal School Opportunity
研究了不平等的学校机会如何影响代际收入流动和人力资本积累，发现学校机会不平等因匹配效应提高平均人力资本，但多数情况下降低代际流动性，对美国数据的模拟显示学校均等化和废除种族隔离政策能以较小效率成本提升流动性。
Abstract We analyse the impact of unequal school opportunity on intergenerational income mobility and human capital accumulation. Building upon the classical Becker–Tomes–Solon framework, we use a regime-switch model allowing for differences in income transmission across groups. We find that unequal school opportunity raises average human capital because of assortative matching. However, because income dispersion tends to be higher at the top, in most cases unequal school opportunity decreases intergenerational mobility. Calibrating the model to the USA, simulations suggest that school equalisation and desegregation policies have positive effects on mobility at relatively small efficiency costs.
