We argue that the narrative of variety-induced gains from trade in differentiated goods needs revision. If producing differentiated varieties of a good requires differentiated skills and if the work force is heterogeneous in these skills, then firms are likely to have monopsony power. We show...

We present the first evidence that international emigrant selection on education and earnings materializes through occupational skills. Combining novel data from a representative Mexican task survey with rich individual-level worker data, we find that Mexican migrants to the United States have...

We study the interaction between the optimal immigration policy of a host country and education policy of a source country in a model of international migration of skilled workers. Acquisition of human capital is driven by the academic and career opportunities at home and abroad. Greater...

I investigate the effect of attitudes toward migrants on the average skill composition of immigrants in destination countries. A model is presented showing that negative attitudes toward migrants can reduce the average skill composition. The intuition for the result is that the highly skilled...

The paper studies the effect that skilled labour mobility has on efficient education policy. The model is one of two periods in which a representative taxpayer decides on labour, education, and saving. The government can only use linear tax and subsidy instruments. It is shown that the mobility...

This paper investigates the welfare consequences of immigration policies in a model with two types of labour, skilled and unskilled, and international capital mobility. The paper examines the effect of government policies - which change the immigration cost and causes immigration of one type of...

This paper studies the labor market impact of documented and undocumented immigration in a model with search frictions and non-random hiring. Since they accept lower wages, firms obtain a higher match surplus from hiring immigrants rather than natives. Therefore, immigration results in the...

How skills acquired in vocational education and training (VET) affect wages and employment is not clear. We develop and estimate a search and matching model for workers with a VET degree. Workers differ in interpersonal, cognitive and manual skills, while firms require and value different...

This paper investigates regional or international transfers as a means to prevent immigration into unemployment. We analyze a two-country model with free migration in which the rich country is characterized by minimum wage unemployment. Matching grants for investment in infrastructure are...

We introduce unemployment and endogenous selection of workers into different skill-classes in a trade model with two sectors and heterogeneous firms. This allows us to study the distributional consequences and the skill-specific unemployment effects of trade liberalization. We show that the...
