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 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...

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...

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...

The vast literature on the effects of immigration on wages and employment is plagued by likely endogeneity and aggregation biases. Ours is among the first papers to address both of these issues by means of causality analysis and by accounting for human capital endowments. Our analysis confirms...

We evaluate the effects of international outsourcing and labor taxation on wage formation and equilibrium unemployment in dual labor markets. Outsourcing promotes wage dispersion between the high-skilled and low-skilled workers. Higher domestic low-skilled wage tax, higher payroll tax and lower...

Tax competition between two governments who choose nonlinear income tax schedules to maximize the average utility of its residents when skills are unobservable and labor is perfectly mobile is examined. We show that there are no Nash equilibria in which there is a skill type that pays positive...

In this paper we employ a tax-competition model to demonstrate that in the presence of migration the re-distributive advantage of a non-linear income tax system over a linear (flat) one is significantly mitigated relative to the autarky (no-migration) equilibrium. When migration threats are...
