教育收益率估算中的几个方法问题

Some Econometric Problems in Estimating the Rate of Return in Education

根据明瑟收入方程估算教育收益率的方法在经验研究中得到了广泛应用，但由于遗漏变量、测量误差、选择偏差和异质性等问题的存在，采用OLS方法估算的教育收益率是有偏误的，本文从上述四个方面较为详尽地讨论了如何纠正OLS估计的偏差。

The OLS estimator for the rate of return in education is based on Mincerian earning equation. But Mincerian earning equation has some econometric problems， such as omitted variable， measurement error， selection bias， and heterogeneity. This paper presents a discussion on how to reduce the weaknesses of Mincerian equation.
