The Political Impact of Immigration: Evidence from the United States
利用1990-2016年美国县级数据，研究发现高技能移民流入降低共和党得票率，低技能移民流入则提高，且该效应主要通过影响现有公民的投票行为实现，不受移民原籍国和种族影响。
This paper studies the impact of immigration to the United States on the vote share for the Republican Party using county-level data from 1990 to 2016. Our main contribution is to show that an increase in high-skilled immigrants decreases the share of Republican votes, while an inflow of low-skilled immigrants increases it. These effects are mainly due to the indirect impact on existing citizens’ votes, and this is independent of the origin country and race of immigrants. We find that the political effect of immigration is heterogeneous across counties and depends on their skill level, public spending, and noneconomic characteristics.
