Recent empirical evidence seems to show that temporary migration is a widespread phenomenon, especially among highly skilled workers who return to their countries of origin when these begin to grow. This paper develops a simple, tractable overlapping generations model that provides a rationale...

This paper investigates the eectiveness of immigration control policies when the duration of stay of illegal immigrants is endogenous because they may return home voluntarily. It shows that return intentions matter. First, we nd that spending on border enforcement can potentially increase the...

We determine workforce composition and wages in rms in the presence of productivity spill-overs between co-workers. In equilibrium, workers' wages depend on the production struc- ture of rms, own group size, and aggregate workforce composition in the rm. We estimate the wage eects of workforce...

Illegal immigration is a major policy challenge in Europe, in particular in countries on the external border of the EU such as Italy or Spain. However, there are likely to be important eects on the rest of the EU, too, depending on the policies against illegal immigration in border countries....

This paper studies the implications of asymmetric fiscal stabilization policy for the budget deficit. In our model, the government is more concerned about downturns than upturns in economic activity and therefore conducts fiscal stabilization policy in a precautionary way. We show that this type...

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

Immigration policies are generally protectionist, yet positive immigration quotas often exist for workers in specic occupations where the native labor supply is scarce. This paper determines occupation-specic immigration quotas in a political economy framework with endogenous prices and compares...

This paper develops a model to analyze the effects of immigration by skill on the outcome of a majority vote among natives on both the size as well as the composition of public spending. Public spending can be of two types, spending on rival goods (transfers) and on non-rival goods (public...
