The supply of foreign talent: how skill-biased technology drives the location choice and skills of new immigrants
利用瑞士各地区因产业构成不同而受信息通信技术（ICT）影响程度差异，研究发现ICT采用更快的地区，大学学历移民的就业和工资增长更显著，且吸引了更多高学历移民流入。
Abstract An important goal of immigration policy is facilitating the entry of foreign-born workers whose skills are in short supply in destination labor markets. In recent decades, information and communication technology (ICT) has fueled the demand for highly educated workers at the expense of less-educated groups. Exploiting the fact that regions in Switzerland have been differentially exposed to ICT due to their pre-ICT industrial composition, we present evidence suggesting that more exposed regions experienced stronger ICT adoption, accompanied by considerably stronger growth in relative employment and wage premia for college-educated workers. Following this change in the landscape of relative economic opportunities, we find robust evidence that these regions experienced a much larger influx of highly educated immigrants in absolute terms as well as relative to lower educated groups. Our results suggest that immigrants’ location decisions respond strongly to these long-run, technology-driven changes in their economic opportunities.
