The Impact of Immigration on Firm-Level Offshoring
利用丹麦的自然实验和雇主-雇员匹配数据，研究发现外来移民涌入减少了企业将工作岗位转移到国外的行为，但移民与母国的联系会增加企业向该国离岸外包的可能性。
This paper studies the relationship between immigration and offshoring by examining whether an influx of foreign workers reduces the need for firms to relocate jobs abroad. Using a Danish natural experiment and their employer-employee matched data set covering the universe of workers and firms (1995–2011), our findings show that an exogenous influx of immigrants into a municipality reduces firm-level offshoring at both the extensive and intensive margins. While the multilateral relationship is negative, a subsequent bilateral analysis shows that immigrants have connections in their country of origin that increase the likelihood that firms offshore to that particular foreign country.
