Doctoral Dissertation Research: The Impacts of Underemployment in the New Economy

博士论文研究：就业不足对新经济的影响近年来，包括就业不足、临时和合同工、兼职和长期失业在内的“不稳定工作”现象迅速增长。尽管社会科学家已经开始研究它对雇主和雇员的影响，但仍然存在重大差距。这个项目考察了两个中心问题。首先，本文采用调查和实地实验的方法，考察了不稳定的就业历史对个体工人未来就业模式的影响。它还考察了这些就业历史的影响如何在不同的人口群体中有所不同。其次，该项目探讨了这种转变对依赖这些临时员工的组织中的全职永久员工的影响。更广泛的影响最近的经济衰退导致不充分和失业率不断上升。这项研究的结果可能会提高我们对美国部门和经济变化以及日益严重的收入不平等的理解。这项研究的结果可能会对普通公众以及旨在创造永久性和临时性就业机会的政策努力感兴趣。调查结果也可能引起雇主的兴趣，对他们来说，裁员和招聘战略既有已知的机会成本，也有未知的机会成本。

SES-1203135Devah Pager and David PedullaPrinceton UniversityAbstractDoctoral Dissertation Research: The Impact of Underemployment in the New EconomyIn recent years, a phenomenon called "precarious work," which includes underemployment, temporary and contract employment, part-time work, and long-term unemployment, has grown rapidly. While social scientists have begun to address its consequences for employers and employees, important gaps remain. This project examines two central issues. First, using survey- and field-experimental methods, the dissertation examines the impact of precarious employment histories on future employment patterns for individual workers. It also examines how the effects of these employment histories differ across demographic groups. Second, the project explores the consequences of this shift for full-time, permanent employees in organizations that rely on such contingent employees. Broader Impacts The recent economic downturn has resulted in growing rates of under- and unemployment. Findings from this research may improve our understanding of sectoral and economic change as well as growing income inequality in the U.S. Findings from this research may be of interest to the general public as well as policy efforts designed to create jobs, both permanent and temporary. Findings may also be of interest to employers, for whom downsizing and hiring strategies carry both known and unknown opportunity costs.
