We exploit rules of class formation to identify the causal effect of increasing the number of immigrants in a classroom on natives test scores, keeping class size constant (Pure Composition Effect). We explain why this is a relevant policy parameter although it has been neglected so far. We show...

Immigration is an important problem in many societies, and it has wide-ranging eects on the educational systems of host countries. There is a now a large empirical literature, but very little theoretical work on this topic. We introduce a model of family immigration in a framework where school...

OECD labor markets have become more “polarized” with employment in the middle of the skill distribution falling relative to the top and (in recent years) also the bottom of the skill distribution. We test the hypothesis of Autor, Levy, and Murnane (2003) that this is partly due to...

There is a considerable empirical literature which compares wage levels of workers who have studied at secondary vocational schools with wages of workers who took academic schooling. In general, vocational education does not lead to higher wages. In some countries where labour markets are...

Re-licensing requirements for professionals that move across borders are widespread. In this Paper, we measure the returns to an occupational license using novel data on Soviet trained physicians that immigrated to Israel. An immigrant re-training assignment rule used by the Israel Ministry of...

This paper studies the effect of an expansion of imported intermediate inputs on establishments’ average task intensities and employment size in a middle-income country. I use confidential matched employer-employee data and information on trade transactions for the universe of Brazilian firms....

The present paper applies several regression-based decomposition methods to analyze the impact of region-, worker-, firm- and sector-specific determinants on the wage level and the continuous increase in wage inequality between 1995 and 2007 in Germany. In contrast to prior studies, more than...

Hardly noticed in Western Europe the fall of the Iron Curtain had also ef-fects on the regional structures of the labour markets in the Central and Eastern Euro-pean Countries (CEEC). I analyse whether during the undoubtedly increasing integration of markets the Czech border region close to the...

How many "American jobs" have U.S.-born workers lost due to immigration and offshoring? Or, alternatively, is it possible that immigration and offshoring, by promoting cost-savings and enhanced efficiency in firms, have spurred the creation of jobs for U.S. natives? We consider a multi-sector...

We examine how within-firm skill premia–wage differentials associated with jobs involving different skill requirements–vary both across firms and over time. Our firm-level results mirror patterns found in aggregate wage trends, except that we find them with regard to increases in firm size....
