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...

This proposal involves the establishment of ‘welfare accounts’ for every person in a country. There are four accounts: a retirement account (covering pensions), an unemployment account (covering unemployment support), a human capital account (covering education and training), and a health...

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...

This paper uses firm level panel data of firm provided training to estimate its impact on productivity and wages. To this end the strategy proposed by Ackerberg, Caves and Frazer (2006) for estimating production functions to control for the endogeneity of input factors and training is applied....

This paper presents new evidence on the distribution of risk attitudes in the population, using a novel set of survey questions and a representative sample of roughly 22,000 individuals living in Germany. Using a question that asks about willingness to take risks in general, on an 11-point...

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...

This paper studies a model of human capital accumulation with real wage rigidity. It is shown that the arbitrage condition between hiring a skilled versus an unskilled worker may be stated as a positive relationship between their relative unemployment rates. It may be the case that this locus is...

This paper suggests that human capital externalities are important in determining whether goods and services should be privately or publicly provided. We study situations where that the cost incurred by an individual provider for providing quality is affected by the human capital of her...
