This paper uses micro data from the Demographic National Survey and the Census in Romania (2002-2003) and in Countries that have received large number of Romanian immigrants over the period 1990-2000 (US, Austria and Spain) to identify the wage earning ability (skills) of migrants and returnees...

We analyze the effect of workforce composition by birthplace on workers' wages. In our model, each worker's productivity may depend on whether co-workers are of the same or of a different birthplace. Wages depend both on the relative size of workers' groups as well as on the production structure...

We develop a model of directed technological change, frictional unemployment 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...

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 effects on the rest of the EU, too, depending on the policies against illegal immigration in border countries....

We determine workforce composition and wages in firms in the presence of productivity spill-overs between co-workers. In equilibrium, workers’ wages depend on the production structure of firms, own group size, and aggregate workforce composition in the firm. We estimate the wage effects of...

We analyze differences in unemployment between natives and immigrants over the business cycle. Using matched employer-employee data for Austria, we find that immigrants' unemployment rate and flows into and out of unemployment are significantly more sensitive to labor market shocks than those of...
