Labor Mobility and Decentralized Government Decision-Making

这项研究的目的是使用模型来分析最优政府行为，这些模型解释了国家或地方政府对个人跨境流动的不完善控制。开发了三种不同的模式，每一种模式都针对劳动力流动的一个特定方面。第一份报告分析了政府无力将移民挡在国境之外所造成的问题。分析将查明从整个区域系统的角度来看，试图限制入境的情况是无效的。这种低效现象不仅在各国内部变得越来越重要，而且在国际环境中也变得越来越重要，例如在西欧加入1992年单一市场倡议时。第二个模型考察了非线性所得税的最优使用，以在包含区域间流动的个人的区域内重新分配收入。这项研究将汇集关于最优所得税和公共产品提供的文献。第三个模型考虑了劳动力在地区间流动成本高昂的情况，并分析了独立政府重新分配收入和保持劳动力跨地区有效配置的能力。这个项目很重要，因为它将提供关于政府政策对劳动力流动的影响的更深层次的理解和新的见解。

The purpose of this research is to analyze the optimal government behavior using models that account for the imperfect control national or local governments exercise over the movements of individuals across their borders. Three different models are developed each of which addresses a particular aspect of labor mobility. The first analyzes the problems created by the inability of governments to keep migrants outside of their borders. The analysis will identify cases in which attempts to restrict entry are inefficient from the viewpoint of the entire system of regions. Inefficiencies of this type are becoming increasingly important not only within countries, but also in international contexts, such as in Western Europe as it enters into the 1992 Single Market initiative. The second model examines the optimal use of nonlinear income taxation to redistribute income within a region containing interregionally mobile individuals. This research will bring together the literature on optimal income taxation and the provision of public goods. The third model considers the situation where labor mobility among regions is costly and analyzes the ability of independent governments to redistribute income and maintain efficient allocation of labor across regions. This project is important because it will provide a deeper understanding and new insights concerning the impact governmental policy on labor mobility.
