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...

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 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...

This work focuses on a temporary guest-worker-type migration of individuals from the middle class of the wealth distribution. The article demonstrates that the possibility of a low-skilled guest-worker employment in a higher wage foreign country lowers the relative attractiveness of the skilled...

With endogenous skills and given technology, labor market integration necessarily lowers welfare of the left-behind in a poor sending country, even if all agents face identical emigration probabilities. This is in sharp contrast to the case of exogenous skill supply
