Educational integration of children with migration background is an important issue in the social sciences. Few studies exist that quantify the disadvantage of immigrant children in education and there has not been any attempt to identify institutional conditions of the education system that...

We revisit and substantially extend the evidence on the importance of instruction time for student achievement on international assessments. We first successfully replicate the estimate of a positive effect of weekly instruction time in the seminal paper by Lavy (Economic Journal, 125,...

In Sweden, females outperform males on compulsory and high school GPAs by a third of a standard deviation, while males outperform females on the Swedish SAT by the same magnitude. We establish that GPAs capture different attributes and skills compared to SAT scores. Differences in motivation and...

We study how the duration of paid parental leave affects the accumulation of cognitive skills among children. We use a reform which extended parental leave benefits from 12 to 15 months for Swedish children born after August 1988 to evaluate the effects of prolonged parental leave on children's...

We quantify the causal effect of schooling on cognitive skills across 21 countries and the full distribution of working-age individuals. We exploit exogenous variation in educational attainment induced by a broad set of institutional reforms affecting different cohorts of individuals in...

Working memory capacity is thought to play an important role for a wide range of cognitive and noncognitive skills such as fluid intelligence, math, reading, the inhibition of pre-potent impulses or more general self-regulation abilities. Because these abilities substantially affect individuals'...

Working memory capacity is a key component of executive functioning and is thought to play an important role for a wide range of cognitive and noncognitive skills such as fluid intelligence, math, reading, the inhibition of pre-potent impulses or more general self-regulation abilities. Because...

We use OECD-PIAAC data to estimate the earnings effects of both years of education and of numerical skills. Our identification strategy exploits differential exposure to educational reforms across birth cohorts and countries. We find that education has the strongest earnings effect. A one...

This paper evaluates the long-term effects of class size in primary school. We use rich administrative data from Sweden and exploit variation in class size created by a maximum class size rule. Smaller classes in the last three years of primary school (age 10 to 13) are not only beneficial for...

We investigate the time investment in cognitive and non-cognitive childcare activities by parents with different educational attainment. In a second step we also investigate this effect for three different child age cohorts. Past research shows that the degree of success in the labour market is...
