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...

I argue that distinguishing between life expectancy at birth and life expectancy beyond the crucial early childhood years affects the relationship between life expectancy and schooling in a meaningful way. In particular, I show that while the change in life expectancy at birth between 1960 and...

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....

We suggest a family bargaining model where human capital investment decisions are made non-cooperatively in a first stage, while day-to-day allocation of time is determined later through Nash bargaining, but with non-cooperative behaviour as the fall back. Several authors have claimed that...

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...

We propose a new theory of the demographic transition based on the evidence that body development during childhood is an important predictor of adult life expectancy. Fertility, childhood development, longevity, education and income growth all result from individual decisions. Parents face a...

This paper derives a model in which workers have firm-specific and industry-specific skills, and in each period there is a non-zero probability that a worker quits. This makes the private discount factor, used by firms in making decisions about hiring and training new workers and firing existing...
