We study the migration policy set by a welfare maximizing government in a model where immigrant workers differ in their skills and are imperfectly matched with heterogenous occupations. The policy fixes a minimum skill level for legal migrants, and foreign workers that fall below it can only...

This paper studies attitudes towards income redistribution in the country of origin among those who stay in a welfare state, and those who emigrate. We find a striking gender difference among Danish emigrants. Majority of men opposes increasing income redistribution, while majority of women...

This paper examines the macroeconomic consequences of the diversion of migration flows away from Germany towards the UK in the course of the EU’s Eastern Enlargement. The EU has agreed transitional periods for the free movement of workers with the new member states from Central and Eastern...

We develop a general equilibrium model of technological change and migration to examine the effects of a change in skill endowments on wages, employment rates and emigration rates of skilled and unskilled workers. We find that, depending on the elasticity of substitution between skilled and...

The concentration of people with diverse socio-cultural backgrounds in particular geographic areas may boost the creation of new ideas, knowledge spillovers, entrepreneurship, and economic growth. In this paper we measure the impact of the size, skills, and diversity of immigration on the...

In 2008, approximately 12 million immigrants lived illegally in the United States, and large numbers of undocumented foreigners resided also in other advanced destination countries. Hence, attempts at controlling immigration flows seem to often fail. If governments are not enforcing their...

Using administrative panel data on the entire population of new labour immigrants to The Netherlands, we estimate the causal effects of labour dynamics on their return decisions. Specifically, the roles of unemployment and re-employment spells on immigration durations are examined. The...

We consider a model of international migration where skills of workers are imperfectly observed by firms in the host country and where information asymmetries are more severe for immigrants than for natives. There are two stages. In the first one, workers in the South decide whether to move and...

In this paper, we investigate how changes in the skill mix of local labor supply are absorbed by the economy. We distinguish between three adjustment mechanisms: through factor prices, through an expansion in the size of those production units that use the more abundant skill group more...

This paper starts with a brief historical overview of immigration in Europe. We then provide a comprehensive analysis of the skill structures of immigrants and their labor market integration in the different European countries, their position in the wage distribution, and the situation of their...
