The Effects of Interrupted Schooling on Wages
利用美国青年纵向调查数据，发现35%的离校者会重返学校；中断学业后再就业的年轻人，其工资增长幅度小于连续完成学业者，且忽略中断的模型会低估早期教育的回报。
Data from the National Longitudinal Survey of Youth reveal that 35 percent of white men who leave school between 1979 and 1988 return to school by 1989. This paper examines the wage effects of these nontraditional enrollment patterns. I estimate a wage model which allows individuals to follow a different wage path before and after their reenrollment and an alternative model which does not account for school and work discontinuities. I find that young men who delay their schooling receive wage boosts that are smaller than those received by their continuously schooled counterparts. Wage models that fail to account for delayed schooling tend to understate the returns to schooling received prior to the start of the career.
