Labor Market Mobility and Migration

该奖项是NSF的社会，行为和经济科学博士后研究奖学金（SPRF）计划和SBE的社会学计划的一部分。SPRF计划的目标是为学术界，工业或私营部门和政府的科学事业准备有前途的早期职业博士级科学家。SPRF的奖励包括在知名科学家的赞助下进行两年的培训，并鼓励博士后研究员进行独立研究。NSF致力于促进来自科学界各部门的科学家，包括来自代表性不足的群体的科学家参与其研究计划和活动;博士后期间被认为是实现这一目标的专业发展的重要水平。每个博士后研究员必须解决推进各自学科领域的重要科学问题。在普林斯顿大学道格拉斯梅西博士的赞助下，该博士后研究金支持一位研究移徙与流动之间关系的早期职业科学家。虽然广泛的研究探讨了移民和移民融入美国社会的模式，但对返回者的重新融入情况知之甚少。本研究旨在探讨回流移民的劳动力市场再整合与重复移民行为。这项研究将指导输出国和接收国的政策制定者监测国际移徙情况，促进返回者重新融入劳动力市场。这项研究提出了四个广泛的问题：第一，什么是最常见的劳动力市场轨迹之间的返回移民？第二，为什么有些返回的移民实现了向上流动，而另一些人则流落到不受管制的经济的边缘？第三，返回的移民重新融入劳动力市场如何影响他们随后的国内或国际移民的风险？第四，回流移民的劳动力市场轨迹和迁移行为在时间和空间上有何不同？为了解决上述问题，PI将1）使用序列分析来确定返回移民之间不同的劳动力市场轨迹; 2）拟合具有竞争风险的风险模型，以预测进入不同劳动力市场轨迹; 3）测试返回者的劳动力市场轨迹与他们的社会经济地位（收入和财富）之间的关联; 4）拟合多项逻辑回归模型，以评估返回移民的劳动力市场轨迹对重新移民到美国或国内移民的可能性的影响; 5）使用分层模型和交互作用项评估劳动力市场重新融合和重复迁移在时间和空间上的变化。本研究对国际移民和经济流动性的研究做出了四点贡献。首先，使用序列分析，PI将映射返回移民的异质性劳动力市场的经验。其次，使用这些轨迹，PI将确定理论预期如何匹配返回移民观察到的劳动力市场经验。第三，该项目通过研究劳动力市场重新融合与重复或国内移民几率之间的关系，提高了对国际移民永久化的认识。第四，研究时间和空间如何反过来影响返乡移民的劳动力市场轨迹和重复移民行为。该奖项反映了NSF的法定使命，通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award was provided as part of NSF's Social, Behavioral and Economic Sciences Postdoctoral Research Fellowships (SPRF) program and SBE's Sociology program. The goal of the SPRF program is to prepare promising, early career doctoral-level scientists for scientific careers in academia, industry or private sector, and government. SPRF awards involve two years of training under the sponsorship of established scientists and encourage Postdoctoral Fellows to perform independent research. NSF seeks to promote the participation of scientists from all segments of the scientific community, including those from underrepresented groups, in its research programs and activities; the postdoctoral period is considered to be an important level of professional development in attaining this goal. Each Postdoctoral Fellow must address important scientific questions that advance their respective disciplinary fields. Under the sponsorship of Dr. Douglas Massey at Princeton University, this postdoctoral fellowship award supports an early career scientist investigating the relation between migration and mobility. While extensive research explores patterns of migration and immigrant incorporation in the United States, comparatively little is known about the reintegration of those who return. This project investigates return migrants labor market reintegration and repeat migration behavior. This study will guide policymakers in sending and receiving countries as they seek to monitor international migration and facilitate returnees' labor market reincorporation. The proposed research addresses four broad questions: First, what are the most common labor market trajectories among return migrants? Second, why do some return migrants achieve upward mobility while others drift to the margins of the unregulated economy? Third, how does return migrants' labor market reintegration affect their risk of subsequent internal or international migrations? Fourth, how do return migrants' labor market trajectories and migration behaviors vary across time and space? To address the stated questions, the PI will 1) use sequence analysis to identify distinct labor market trajectories among return migrants; 2) fit hazard models with competing risks to predict entry into different labor market trajectories; 3) test the association between returnees' labor market trajectories and their socioeconomic status - income and wealth; 4) fit multinomial logistic regression models to assess the effect of return migrants' labor market trajectories on the odds of re-migrating to the United States or migrating internally; 5) use stratified models and interaction terms to assess changes in labor market reintegration and repeat migration across time and space. This study makes four contributions to research on international migration and economic mobility. First, using sequence analysis, the PI will map return migrants' heterogeneous labor market experiences. Second, using these trajectories, the PI will determine how theoretical expectations match return migrants' observed labor market experiences. Third, this project advances knowledge about the perpetuation of international migration by examining the relation between labor market reintegration and the odds of repeat or internal migration. Fourth, this project investigates how time and space in turn shape return migrants' labor market trajectories and repeat migration behavior.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
