High-Skill Migration, Multinational Companies, and the Location of Economic Activity
利用企业级高技能签证数据，发现外国跨国公司雇佣的移民存在显著的母国偏向，并构建量化模型分析移民政策与跨国公司生产对工资和福利的影响。
Abstract This article aims to understand the relationship between high-skill immigration and multinational activity. I assemble a firm-level dataset on high-skill visas and show that there is a large home bias effect: foreign multinationals hire more immigrants from their home countries than from other origins. I then build and estimate a quantitative model that relates multinational production with immigration. First, I impose a restrictive immigration policy in the United States and evaluate how it affects production and wages. Second, I increase the barriers to multinational production and show that immigration is an important channel to quantify the welfare gains generated by multinationals.
