Doctoral Dissertation Research in Economics: Behavioral Responses to Taxation of Foreign Personal Income

这是一项博士论文研究改进资助。coPI将使用独特的数据集来量化高收入个人对外国个人收入税收变化的行为反应，并估计公司代表其员工进行税收规划的程度。许多国家提供大量的税收优惠来吸引高收入的外国人，假设这些新居民会促进当地的经济活动，并产生额外的财政收入，因为他们在他们居住的地方消费、工作和投资。然而，跨国公司可能会实施税收筹划策略，以尽量减少员工的税单。该项目将使用大型行政数据集来了解企业及其员工对税收政策变化的行为反应。该项目将有助于量化为吸引高收入个人而提供的税收优惠的收益和成本。研究结果将有助于为政策辩论提供信息，并将展示大型行政数据集如何为税收政策提供有用的信息。最近的实证研究表明，在移民决策中，某些群体对税收差异反应强烈。然而，目前还不清楚企业在移民决策中扮演什么角色。这些政策对政府收入的影响以及对地方经济的溢出效应也尚不清楚。该项目将描述对外国个人收入征税的行为反应，并估计公司代表其雇员进行税收规划的程度。该分析利用了针对英国非定居个人的税收减免的一系列改革所产生的准实验性差异。政策的变化为我们提供了一个独特的数据源来回答新的研究问题。虽然以前的研究侧重于国内来源收入的税收，但这项工作的重点是外国来源收入和跨国公司可能使用的税收规划策略。该奖项反映了美国国家科学基金会的法定使命，并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 is a doctoral dissertation research improvement grant. The coPI will use a unique data set to quantify the behavioral responses of high-income individuals to changes in the taxation of foreign personal income and estimate the extent to which firms engage in tax planning on behalf of their employees. Many countries offer substantial tax incentives to attract high income foreigners, on the assumption that these new residents will boost local economic activity and generate additional fiscal revenues because they consume, work, and invest where they live. However, multinational firms may implement tax planning strategies to minimize their employees' tax bills. The project will use a large administrative data set to understand the behavioral responses of both firms and their employees to changes in tax policies. The project will help quantify the benefits and costs of tax incentives offered to attract high income individuals. The results will help inform policy debates and will demonstrate how large administrative data sets can offer useful information for tax policies. Recent empirical research shows that certain groups of individuals are highly responsive to tax differentials in their migration decisions. However, it is not yet clear what role firms play in migration decisions. The consequences of these policies on government revenues and the spillover effects on local economies are also not yet clear. The project will characterize the behavioral response to taxation of foreign personal income and estimate the extent to which firms engage in tax planning on behalf of their employees. The analysis exploits quasi-experimental variation generated by a series of reforms to a tax break for non-domiciled individuals in the UK. The policy change gives us a unique data source for answering new research questions. While previous research focused on taxation of domestic source income, this work focuses instead on foreign source income and the possible use of tax planning strategies by multinational firms.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.
