This study develops and estimates a model of the naturalization process in the US. The model is based on both the characteristics of immigrants and features of their countries of origin. The empirical analysis is based on the 2000 US Census...

This paper provides an introduction and overview of my research on the Economics of Language. The approach is that language skills among immigrants and native-born linguistic minorities are a form of human capital. There are costs and benefits associated with this characteristic embodied in the...

This paper shows that outsourcing of parts of workforce in unionized firms leads to wage moderation both in the case of strategic and flexible outsourcing and as long as the share of the outsourced workforce is not too large, this wage-moderation effect on domestic employment outweighs the...

Using two Dutch labour force surveys, employment assimilation of immigrants is examined. We observe marked differences between immigrants by source country. Non-western immigrants never reach parity with native Dutch. Even second generation immigrants never fully catch up...

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...

Identifying the effect of parental incomes on child outcomes is difficult due to the correlation of unobserved ability, education levels and income. Previous research has relied on the use of instrumental variables to identify the effect of a change in household income on the young adult...

This paper studies in the presence of flexible outsourcing the effects of outsourcing costs, productivity of outsourcing, wage tax and tax exemption in an imperfectly competitive labour markets when labour unions and firms negotiate wages and the impacts of labour tax progression on domestic...

This study examines how minimum wage laws affect the employment and earnings of low-skilled immigrants and natives in the U.S. Minimum wage increases might have larger effects among low-skilled immigrants than among natives because, on average, immigrants earn less than natives due to lower...

We study the role of ethnic networks in migrants` job search and the quality of jobs they find in the first years of settlement. We find that there are initial downward movements along the occupational ladder, followed by improvements...

Since little is known about the degree of bias in estimated fixed effects in panel data models, we run Monte Carlo simulations on a range of different estimators. We find that Anderson-Hsiao IV, Kiviet’s bias-corrected LSDV and GMM estimators all perform well in both short and long panels...
