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...

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....

In this inaugural lecture, I will estimate the effects on language skills of two characteristics of school populations: average/share and diversity, both on the ethnic and the sociocultural dimension. I will use the cross-national PISA 206 data, for both 15-year-old native pupils and pupils with...

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...

This note analyzes income differences between foreigners and natives in Germany. Using social survey data (ALLBUS) for 2012, I use Mincer style quantile regressions and Oaxaca-Blinder decompositions to estimate the size of the income differential. People not born in Germany, have an income lose...

This paper combines representative worker-level data that cover time-varying job-level task characteristics of an economy over a long time span with sector-level bilateral trade data. We carefully create longitudinally consistent workplace characteristics from the German Qualification and Career...

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...
