We explore the adoption data approach to estimating causal effects of parental education and income on the same outcomes of their children. Thanks to a data set drawn from Swedish population registers with detailed information on biological background and history of adoptees, we can test basic...

We use unique Swedish data with information on adopted children's biological and adoptive parents to estimate intergenerational mobility associations in earnings and education. We argue that the impact from biological parents captures broad prebirth factors, including genes and prenatal...

We use unique Swedish data to estimate intergenerational associations between adoptees and their biological and adoptive parents. We argue that the impact from biological parents captures broad pre-birth factors, including genes and prenatal environment, and the impact from adoptive parents...

In this article, I use within-school variation to estimate the effect of tracking. I exploit the fact not only that different tracking policies were practiced simultaneously in Swedish compulsory schools but also that tracking policies changed overtime within schools. I estimate not only if...

In this paper I use a rich dataset in order to observe each student in different subjects and courses over time. Unlike most peer studies, I identify the peers and the teachers that each student has had in every classroom. This enables me to handle the simultaneity and selection problems, which...

Whether or not to differentiate - or track - students according to ability has been debated over the years. In Sweden, secondary schools that practiced tracking and schools that did not practice tracking existed simultaneously from 1980 to 1997. This variation in tracking status between schools...

Girls outperform boys in school. We investigate whether the gender performance gap can be attributed to the fact that the teacher profession is female dominated, that is, is there a causal effect on student outcomes from having a same-sex teacher? Using data on uppersecondary school students and...

This paper studies technical efficiency for Swedish employment offices between 2004 and 2010. Efficiency is computed using a semi-dynamic DEA-framework. On the input side we include a measure of input quality and we also control for services that are carried out by private contractors. On the...
