In this paper we analyze the effect of immigrants on natives' job specialization in Western Europe. We test whether the inflow of immigrants changes employment rates or the chosen occupation of natives with similar education and age. We find no evidence of the first and strong evidence of the...

We study migration policy enforcement by an elected government. The policy-maker faces uncertainty on the supply of migrants, but has more information than the public on its preferences and the extent and effectiveness of its enforcement activities. We show that a utilitarian government...

While anecdotal evidence suggests that interest groups play a key role in shaping immigration policy, there is no systematic empirical analysis of this issue. In this paper, we construct an industry-level dataset for the United States, by combining information on the number of temporary work...
