Estimating (Easily Interpreted) Dynamic Training Effects from Experimental Data
利用JTPA实验数据，估计了弱势女性参与培训对就业状态转换的动态效应，发现课堂培训显著缩短了失业持续时间，对设计更有效的培训项目有参考价值。
We estimate the effect of endogenous training participation on transitions in and out of employment for disadvantaged women in the Job Training Partnership Act (JTPA) study. Decomposing the effect of training on employment into its effects on transitions in and out of employment has the potential to develop more effective programs. We also consider a potentially serious identification problem that arises when individuals do not undertake training immediately, and we propose a test to shed light on this problem. We find that this problem is not important in our context. JTPA classroom training substantially reduced unemployment durations, and thus it complements programs that increase employment durations.
