Wage Effects of High-Skilled Migration: International Evidence
利用国际双边移民流数据，研究高技能移民对目的地国和来源国技能工人工资及生产率的影响，通过多种工具变量策略解决内生性问题。
The international migration of high-skilled workers may trigger productivity effects at the macro level such that the wage rate of skilled workers increases in host countries and decreases in source countries. We exploit data on international bilateral migration flows and provide evidence consistent with this theoretical hypothesis. We propose various instrumentation strategies to identify the causal effect of skilled migration on log differences of GDP per capita, total factor productivity, and the wages of skilled workers between pairs of source and destination countries. These strategies aim to address the endogeneity problem that arises when international wage differences affect migration decisions.
