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...

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...

This paper presents a tractable dynamic general equilibrium model that can explain cross-country empirical regularities in geographical mobility, unemployment and labor market institutions. Rational agents vote over unemployment insurance (UI), taking the dynamic distortionary effects of...

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...

Advocates of apprenticeship programmes often argue as if it is simply a matter of historical accident that such investment by US firms has been hindered. This paper explores the structure of incentives underpinning the German system of apprenticeship training. First, we describe three...

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...

In this paper, we incorporate a positive theory of unemployment insurance into a dynamic overlapping generations model with search-matching frictions and on-the-job learning-by-doing. The model shows that societies populated by identical rational agents, but differing in the initial distribution...

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....
