Thanks to extraordinary and exponential improvements in data storage and computing capacities, it is now possible to collect, manage, and analyze data in magnitudes and in manners that would have been inconceivable just a short time ago. As the world has developed this remarkable capacity to...

A growing literature documents the positive long-term effects of policy-induced improvements in early-life health and nutrition. However, there is still scarce evidence on early-life health programs targeting a large share of the population and the role of such programs in increasing...

We examine the labor market consequences of an exogenous increase in the supply of skilled labor in several cities in Norway, resulting from the construction of new colleges in the 1970s. We find that skilled wages increased as a response, suggesting that along with an increase in the supply...

Using matched worker/plant level data for Norway, theories explaining the change in skill composition are assessed using direct evidence on the job creation and destruction for high, medium and low skilled workers. Skill based job creation is analysed in detail for plants in a high-skill service...

Whether increasing resource use in schools has a positive effect on pupil performance has occupied governments, parents and researchers for decades. A main challenge when trying to answer this question is to separate the effects of school resources from the effects of pupils' family background,...

Despite important policy implications associated with the allocation of education resources, evidence on the effectiveness of school inputs remains inconclusive. In part, this is due to endogenous allocation; families sort themselves non-randomly into school districts and school districts...

Older workers typically possess older vintages of skills than younger workers, and they may suffer more from technological change. Experienced workers may nevertheless have accumulated human capital making them suitable for adopting new technologies. On the other hand, to adjust to new...

There is massive cross-sectional evidence that children of more educated parents outperform their schoolmates on tests, grade repetition and in educational attainment. However, evidence for causal interpretation of this association is weak. Within a rich census level data set for Norway, we...

This paper uses a unique data set with nearly career-long earnings histories to provide evidence on the returns to schooling in current and lifetime earnings. We use these results to assess the importance of life-cycle bias in earnings regressions using current earnings as a proxy for lifetime...

Increasing mothers' labour supply in a child's preschool years can cause a reduction in time investments that lead to a negative direct effect on mid-childhood and teenage outcomes. But as mothers' work hours increase, income will rise. We ask whether income can compensate for the negative...
