The Impact of Intervention on Economic Status

这个项目继续研究劳动力市场的运作。在之前的奖项中，研究者发表了一些关于各种相关主题的论文，包括：(a)收入和收入分配的决定因素，(b)人力培训计划对收入的影响，纵向数据的价值，以及选择偏差模型的计量经济学的更一般问题的分析，(c)开发和测试持续时间分析模型。这个项目将在三个广泛的主题方面扩展以前的工作。第一个是关于选择偏差问题的非实验估计器的发展和评估。该方法用于进一步评估人力培训计划对收入、就业和失业的影响。将评估各种类型的计量经济估计器的好处。我们还将探讨纵向数据和实验数据的好处，并将重新分析先前工作中分析的数据集，并开发各种新的估计器。第二个主题是计量经济持续时间分析。将开发和评估使用具有不可观测成分的数据的持续时间模型的估计器。第三个主题侧重于分析1910年至1980年期间南卡罗来纳州劳动力市场的黑人工资结构和收入。这一时期的数据将用于评估政府压力、学校教育的增长以及长期和周期性市场因素在解释1960年代中期该州黑人就业和工资突破方面的相对重要性。

This project continues research into the operation of labor markets. Under the previous award the investigator published a number of papers focusing on a variety of related topics including: (a) the determinants of earning and the distribution of income, (b) an analysis of the impact of manpower training programs on earnings, the value of longitudinal data, and the more general issues of the econometrics of selection-bias models, (c) the development and testing duration analysis models. This project will extent the previous work in terms of three broad topics. The first is on the development and assessment of non-experimental estimators for selection-bias problems. The methodology is applied to the further evaluation of the impact of manpower training programs on earnings, employment, and unemployment. The benefits of various types of econometric estimators will be assessed. The benefits of longitudinal and experimental data well also be explored, and data sets analyzed in the previous work will be re-analyzed and a variety of new estimators will be developed. The second topic is on econometric duration analysis. An estimator for duration models using data with unobservable components will be developed and evaluated. The third topic focuses on the analysis of black wage-structures and earnings in the South Carolina labor market during the 1910 to 1980 period. Data from this period will be used to assess the relative importance of government pressure, the growth in schooling, and secular and cyclical market factors in accounting for the breakthrough in black employment and wages observed in that state during the mid 1960's.
