The Effect of Immigration along the Distribution of Wages
分析移民对本土工人工资的影响，发现移民压低工资分布底部20%的工资，但略微提高上部的工资，整体影响略偏正面。
This paper analyses the effect immigration has on the wages of native workers. Unlike most previous work, we estimate wage effects along the distribution of native wages. We derive a flexible empirical strategy that does not rely on pre-allocating immigrants to particular skill groups. In our empirical analysis, we demonstrate that immigrants downgrade considerably upon arrival. As for the effects on native wages, we find a pattern of effects whereby immigration depresses wages below the 20th percentile of the wage distribution but leads to slight wage increases in the upper part of the wage distribution. This pattern mirrors the evidence on the location of immigrants in the wage distribution. We suggest that possible explanations for the overall slightly positive effect on native wages, besides standard immigration surplus arguments, could involve deviations of immigrant remuneration from contribution to production either because of initial mismatch or immigrant downgrading.
