Worker Power, Immigrant Sorting, and Firm Dynamics

This paper examines how worker power shapes the allocation of immigrants across firms, and the subsequent consequences of such sorting on firm performance and the careers of incumbent workers. Our analysis highlights several key results. First, unions push immigrants to enter less unionized, lower-paying, and lower-quality firms. Second, the less unionized firms are able to utilize the access to cheaper immigrant labor to scale up production, thereby outcompeting the more unionized firms and capturing market share. Third, incumbent workers in less unionized firms benefit by shifting into management positions and capturing some of the firm’s increased rents. Fourth, despite benefiting incumbent workers in less unionized firms, these workers are more likely to become union members themselves in response to greater contact with new immigrants. Broadly, our results cut across nearly all sectors, but are heightened in labor intensive firms, and muted in competitive markets.
