Individuals match on length and type of education. We investigate whether the systematic relationship between educations of partners is explained by opportunities (e.g. low search frictions) or preferences (e.g. complementarities in household production or portfolio optimization). We find that...

Socioeconomic (SES) gaps in academic achievement are well documented. We show that a very similar gap exists with respect to genetic differences measured by a polygenic score (PGS) for educational attainment. The genetic gap increases during elementary school, but only among the low SES...

We study how children's socio-emotional skills and well-being in adolescence are affected by an increase in the duration of parental care during infancy. Exploiting a Danish reform that extended paid parental leave in 2002 and effectively delayed children's entry into formal out-of-home care, we...

It is widely recognised that genetics and family investments both matter for children's development. However, the two are often treated as separate factors where the higher importance of one implies a lesser role of the other. In this paper, we challenge this view and show that genes and family...

This paper uses Danish register-based data for the population of children born in 1990-1997 to investigate the effects on parents of having a child with attention-deficit/hyperactivity-disorder (ADHD). Ten years after birth, parents of children diagnosed with ADHD have a 75% higher probability...

There is a large gender gap in advanced math coursework in high school that many believe exists because girls are discouraged from taking math courses. In this paper, we exploit an institutional change that reduced the costs of acquiring advanced high school math to determine if access is, in...

This paper estimates effects of early ADHD medication use on key human capital outcomes for children diagnosed with ADHD while using rarely available register based data on diagnoses and prescription drug purchases. Our main identification strategy exploits plausible exogenous assignment of...

During the last decade knowledge about human behavior from psychology and sociology has enhanced the field of economics of education. By now research recognizes cognitive skills (as measured by achievement tests) and soft skills (personality traits not adequately measured by achievement tests)...

This paper estimates how peers' achievement gains are affected by the presence of potentially disruptive and emotionally sensitive children in the school-cohort. We exploit that some children move between schools and thus generate variation in peer composition in the receiving school-cohort. We...
