Workplace segregation and the labour market performance of immigrants
利用德国登记数据，研究发现移民第一份工作中同国籍同事比例每提高10个百分点，长期就业率下降约3个百分点，原因包括人力资本积累和求职网络质量下降。
This paper studies the effect of conational coworkers in an immigrant’s first job on subsequent labour market outcomes using German register data. I instrument for the conational share using idiosyncratic variation in firm hiring in the local labour market where the immigrant searches for work. A ten percentage point increase in the initial conational share lowers employment by around 3 percentage points in the long-run. Survey evidence suggests that a higher conational share leads to higher self-employment and unemployment, rather than re-migration. Furthermore, both differential host country-specific human capital accumulation and changes in job search outcomes contribute to the employment effect. • Working with more conationals lowers an immigrant’s subsequent employment. • Lower employment not explained by increased self-employment or return migration. • More conationals reduces the quality of immigrants’ subsequent job search network.
