内容简介：
Based on the heterogeneous education return framework, this paper esti- mates the marginal treatment effect ofcollege expansion on college premi- ums in China. Our findings are triple.Firstwe capture heterogeneous col- lege premiums after college expansion,especially in urban areas and prov- inces with abundant education resources.Secondthe treatment effects follow a quantitative sequence ofATT(Average Treatment Effect on Treat ed)>LATE(Local Average Treatment Effect)>ATE(AverageTreatment Ef fect)>TNT(Average Treatment Effect on Non-Treated)which reconciles the puzzle that instrumental-variable estimates are always larger than ordi nary-least- square estimates in the literature.Due to the heterogeneous edu cation returns, college premiums for compliers decline after college expan sion. Third, by evaluating several potential education policies, we find that policies aiming at enhancing the college entrance probability by a propor tion are ineffective and will even lead toresource misallocation This paper furthers our understanding of education premiums and sheds new light on the quality mechanism governing the effect of college expansion on college premiums.
