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...

The paper analyses the contemporary organizational restructuring of production and work and derives some salient implications for the labour market. The analysis focuses on the switch from occupational specialization at 'Tayloristic' organizations to multi-tasking at 'holistic' organizations....

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....

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 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...

The paper examines the implications of an important aspect of the ongoing reorganization of work – the move from occupational specialization towards multi-tasking – for centralized wage bargaining. The analysis shows how, on account of this reorganization, centralized bargaining becomes...

The paper examines the determinants of the division of labour within firms. It provides an explanation of the pervasive change in work organization away from the traditional functional departments and towards multi-tasking and job rotation. Whereas the existing literature on the division of...
