The Economics and Econometrics of Self-Selection with Applications to the Evaluation of Government Training Programs and to Understanding Sectoral Wage Inequality

本研究的目的是评估政府培训计划对学员的影响，并分析收入不平等的决定因素。在这项分析中特别关注了选择偏差，这项研究将为开发考虑这种偏差的估计模型奠定理论基础。本研究将包括利用这些模型进行的三项实证研究。第一个将使用最近可用的实验和非实验数据来评估领先的联邦人力培训计划--就业培训伙伴法案--的影响。这项研究的目的是确定合格人群中计划意识的决定因素，计划的申请、登记、安置和长期劳动结果的决定因素。这项研究将对就业培训计划的有效性提出新的见解。第二项研究将考察随机化在评估社会项目方面的效果。最后，第三部分将利用衡量不平等的新方法来研究工资不平等的根源。这项研究很重要，因为它将开发评估社会项目的新方法，并将为收入不平等问题提供新的见解。

The purpose of this research is to evaluate the effects of government training program on trainees and to analyze the determinants of income inequality . Special attention is paid to selection bias in this analysis, and the study will develop a theoretical foundation for developing estimating models that take into account this bias. The research will include three empirical studies utilizing these models. The first will use recently available experimental and non-experimental data to evaluate the impacts of the leading Federal manpower training program--the Job Training Partnership Act. The objective of this study is to ascertain the determinants of program awareness among the eligible population, the determinants of application, enrollment, placement, and long-run labor outcomes of the program. This study will present new insights about the effectiveness of the job training program. The second study will examine the effects of randomization in evaluating social programs. Finally, the third part will investigate the sources of wage inequality utilizing new methods for measuring inequality. This research is important because it will develop new methods for evaluating social programs, and it will provide new insights about the problem of income inequality.
