Do Immigrants Displace Native Workers? Evidence from Matched Panel Data

Using matched employer-employee data, we analyse the impact of immigrants on natives’ employment in Portugal. Using different model specifications, we show that the natives and immigrants are ‘complements’ at most occupation levels, in the sense that both types are hired when the number of immigrants is increasing. Controlling for different skill-level groups as well as for temporary and permanent jobs, the estimates show that, contrary to the evidence from some existing literature, the natives at the lower end of the skills spectrum are not affected by the presence of immigrants as well. There is, however, some evidence that when the number of immigrants in the firm is decreasing, natives tend to replace immigrants.
