本文利用第一个青年队列研究（YCS）的数据来分析英格兰和威尔士青年培训计划（YTS）的有效性，即其在个人层面对年轻人就业前景的影响。该分析超越了以前的工作，因为它明确处理了样本选择偏差和异方差。估计切换双变量概率模型，发现它优于单变量概率模型和具有 YTS 参与虚拟的双变量概率模型。分析表明，之前对 YTS 的研究可能低估了该计划对参与者找到就业机会的影响的规模和可变性。版权所有 1994 英国皇家经济学会。
In this paper, data from the first Youth Cohort Study (YCS) are used to analyze the effectiveness of the Youth Training Scheme (YTS) in England and Wales in terms of its impact, at an individual level, on the employment prospects of young people. The analysis goes beyond previous work in that it explicitly deals with sample selection bias and heteroscedasticity. A switching bivariate probit model is estimated and is found to be preferred to both the univariate probit model and the bivariate probit model with a YTS participation dummy. The analysis suggests that previous studies of YTS may have underestimated both the size and variability of the effect that the scheme had on participants' chances of finding employment.
