Computerization and immigration: Theory and evidence from the United States
研究了计算机化技术变革如何吸引移民从事手工服务职业，并发现移民流入缓解了本土工人因技术变革面临的就业和工资极化问题。
Abstract Recent technological changes have been characterized as “routine‐substituting” because they reduce demand for routine tasks and increase demand for analytical and service tasks. Little is known about how these changes have impacted immigration, or task specialization between immigrants and native‐born individuals. In this paper, we show that such technological progress has attracted immigrants who increasingly specialize in manual‐service occupations. We also suggest that openness to immigration attenuated the job and wage polarization faced by native‐born from technological changes. We explain these facts with a model of technological progress and endogenous immigration. Simulations show that unskilled immigration attenuates the drop in routine employment proceeding from technological change, enhances skill upgrading for native‐born and raises economy‐wide productivity and welfare.
