CAREER: Within City, Across Seasons or Across Borders: The Economics of Labor Movements

这个职业研究项目将研究贫困人口劳动力迁移的经济影响。这项研究将使用现代复杂的方法来研究跨国、国内和城市内劳动力流动的好处和成本。与劳动力移民相关的许多问题未来可能会增加，了解移民可能产生的溢出效应是美国和世界的一个重要关切。例如，世界上许多大城市都面临着拥堵和环境压力，是否以及如何投资交通基础设施是现在要讨论的一个关键问题。了解如何制定政策，最大限度地发挥移徙作为减贫战略的作用，对世界各地的发展大有可为。这项研究的结果将为与劳动力市场、城市化和国际关系相关的政策提供指导，从而帮助美国制定信息灵通的政策，促进经济增长，并了解移民可能产生的溢出效应。这是美国和世界的一个重要关切。该提案包含三个相互关联的项目，以研究国内和跨界移徙问题。第一个项目试图通过两个阶段的随机对照研究来量化移民回报的异质性。未来的国内移民将得到“低”或“高”的补贴。有些获得“低”补贴的人在做出移民决定后，会惊讶地发现“高”补贴。第二个项目将使用观察性面板数据和一系列实验来研究大规模公共交通投资的经济效应和分配后果。第三个项目使用墨西哥-美国移民流动的数据集，开发和估计了一个以美墨边境移民为重点的两国区域移民空间均衡模型。在城市化日益加剧、人口跨境流动、移民在世界范围内是一个有争议的话题的今天，提供移民的好处和成本的定量和严格的证据是必不可少的。拟议的研究将产生新的数据集并传播研究结果。贯穿这些项目的一个主题是将微观经济估计和区域协调机制纳入空间一般均衡模型。这一方法也涉及主要的田野调查数据收集，这是一种新的方法，将有助于开发方法和评估方法以取得进展。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。该奖项反映了NSF的法定使命，并通过使用基金会的智力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 CAREER research project will study the economic impacts of labor migration of the poor. The research will use modern sophisticated methods to study the benefits and costs of labor movements across countries, within countries, and within cities. Many of the issues associated with labor migration are likely to increase in the future and understanding the possible spillover effects from migration is an important concern in the United States and the world. For example, many large cities in the world are facing congestion and environmental stress and whether and how to invest in transportation infrastructure is a key question to be discussed now. Understanding how to develop policies to maximize the role of migration as a poverty-reduction strategy has great promise for development around the world. The results of this research will provide guidance on policy relating to labor markets, urbanization, and international relations, thus helping the US develop well-informed policies that enhance economic growth as well understanding the possible spillover effects from migration. This is an important concern in the United States and the world. The proposal contains three interlinked projects to study internal and cross-border migration. The first project seeks to quantify the heterogeneity in returns to migration through a two-stage RCT. Prospective internal migrant will be offered either "low" or "high" subsidies. Some of those who receive "low" subsidies will be surprised with a "high" subsidy after they have made a migration decision. The second project will use an observational panel data and a suite of experiments to study the economic effects and distributional consequences of a large public transportation investment. The third project develops and estimates a binational regional spatial equilibrium model of migration focusing on the US-Mexico border migration using a dataset of Mexico-US migration flows. Providing quantitative and rigorous evidence of the benefits and costs of migration is indispensable now when there is increasing urbanization, movement of people across borders, and migration is a controversial topic world-wide. The proposed research will generate new datasets and disseminate the research findings. A theme running through the projects is the incorporation of microeconomic estimates and RCTs into spatial general equilibrium models. This method that also involve primary fieldwork data collection, is new and will help develop the methodology and estimation approaches to make progress.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.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.
