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...

The Roy-Borjas model predicts that international migrants are less educated than nonmigrants because the returns to education are generally higher in developing (migrant-sending) than in developed (migrant-receiving) countries. However, empirical evidence often shows the opposite. Using the case...

This paper explores the impact of undocumented as opposed to documented immigration in a model featuring search frictions and non-random hiring that is consistent with novel empirical evidence presented. In this framework, undocumented immigrants' wages are the lowest of all workers due to their...

We study the labour market impact of a major shock of return migration, following the end of the Portuguese Colonial War in 1974. The retornados influx is unique because of its size (half a million people in a country of nine million), and similarity with the native population (almost 80% of the...

The paper provides an overview on recent trends of immigration in OECD countries and on the possible effects of immigration on labour markets and government budgets. It also discusses migration policies from an economic point of view. By bringing together a bulk of international literature on...

We analyse how institutional and political decisions are intertwined. Citizens who differ in their mobility and ability vote first on labour market integration and afterwards on education policy. The institutional decision on integration influences the succeeding education policy. More...

This paper explores the economic consequences of the enlargement of the European Union with countries from Central and Eastern Europe. We focus on integration aspects that go beyond the reduction of formal trade barriers, namely accession to the internal market and free movement of labour. The...

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...
