Accomplishment-Based Renewal: Evaluating Social Programs

9321048 Heckman本项目有四个相互关联的目标：(1)完成对工作培训合作法案（JTPA）的评估，该法案是在之前的NSF资助下开始的。该项目研究自我选择偏差（如果有的话），它表征了参与者和非参与者之间在收入、就业和工资方面的差异，并着眼于利用现成的非实验数据制定严格的、有经济动机的项目评估策略。(2)本研究利用独特的数据建立了基于经验的组织激励模型和组织对外部强制绩效标准的反应。项目的这一部分提供了关于官僚主义经济学和项目经理对激励的反应的新信息。(3)本研究发展并应用计量经济学方法来估计各种可能性之间的动态选择模型，以及这些选择的回报。(4)该研究考虑了社会实验案例的实证、经济和计量基础。将对社会实验的好处和局限性进行理论和实证研究。将调查培训中心对随机化的反应。该项目的一个目标是出版一本关于严格评估社会项目的书，重点是人力培训项目。

9321048 Heckman This project has four interrelated objectives: (1) To complete an evaluation of the Job Training Partnership Act (JTPA) begun under the previous NSF grant. The project studies the self-selection bias (if any) that characterizes the differences in earnings, employment and wages between participants and non-participants with an eye toward developing rigorously, economically motivated program evaluation strategies using readily available non- experimental data. (2) The study exploits unique data to develop empirically-based models of incentives in organizations and the responses of organizations to externally mandated performance standards. This portion of the project provides new information on the economics of bureaucracies and the responses of program managers to incentives. (3) The study develops and applies econometric methods for estimating dynamic models of choices among alternative possibilities, and the rewards from these choices. (4) The study considers the empirical, economic and econometric foundations of the case for social experiments. Both theoretical and empirical studies will be conducted on the benefits and limitations of social experiments. The responses of training centers to randomization will be investigated. One goal of the project is to produce a book on the rigorous evaluation of social programs with an emphasis on manpower training programs.
