An alternative approach to estimate the wage returns to private‐sector training
通过将对照组缩小为那些因随机事件未能参加培训的工人，发现培训的工资回报估计值从显著为正降至接近零。
Abstract This paper follows an alternative approach to identify the wage effects of private‐sector training. The idea is to narrow down the comparison group by only taking into consideration the workers who wanted to participate in training but did not do so because of some random event. This makes the comparison group increasingly similar to the group of participants in terms of observed individual characteristics and the characteristics of (planned) training events. At the same time, the point estimate of the average return to training consistently drops from a large and significant return to a point estimate close to zero.
