Modern growth theory puts invention on the center stage. Inventions are created by individuals, raising the question: can we increase number of inventors? To answer this question, we study the causal effect of M.Sc. engineering education on invention, using data on U.S. patents’ Finnish...

We study the evolution of racial educational inequality across US states from 1940 to 2000. We show that throughout this period, despite evidence of convergence, the racial gap in attainment between blacks and whites has been persistently determined by the initial gap. We obtain these results...

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...

In this paper we examine the long term effects of socialization and segregation in schools, on labour market outcomes. We incorporate a model of “informational” peer influence by which beliefs of pupils are affected by exposure to other pupils’ posterior beliefs. Specifically, we focus on...

We propose a dynastic model in which individuals are born in an educated or uneducated environment that they inherit from their parents. We study the role of social networks on the correlation in the parent-child educational status independent of any parent-child interaction. We show that the...

There is relatively little research on peer effects in teenage motherhood despite the fact that peer effects, and in particular social interaction within the family, is likely to be important. We estimate the impact of an elder sister’s teenage fertility on the teenage childbearing of their...

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...

We model educational investment, wages and employment status (full-time, part-time or non-participation) in a frictional world in which heterogeneous workers have different productivities, both at home and in the workplace. We investigate the degree to which there might be under-employment and...

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...

We use a quantile regression framework to investigate the degree to which work-related training affects the location, scale and shape of the conditional wage distribution. Human capital theory suggests that the percentage returns to training investments will be the same across the conditional...
