The Effect of Immigration on Native Self‐Employment
通过理论模型和1980、1990年美国132个大都市区数据，发现自雇移民会挤占本土自雇者数量，但未显著降低其收入，且实际影响大于模型预测。
We examine the impact of immigration on self-employed natives. In a new general equilibrium model of self-employment and wage/salary work, a range of plausible parameter values implies small negative effects of immigration on native self-employment rates and earnings. Using 1980 and 1990 Census microdata, we then examine the relationship between changes in immigration and native self-employment rates and earnings across 132 of the largest U.S. metropolitan areas. We find evidence suggesting that self-employed immigrants displace self-employed natives but do not have a negative effect on native self-employment earnings. The effects are much larger than those predicted by the theoretical model.
