We investigate the spillover effects of early-life medical treatments on the siblings of treated children. We use a regression discontinuity design that exploits changes in medical treatments across the very low birth weight (VLBW) cutoff. Using administrative data from Denmark, we first confirm...

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...

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...

We are the first to investigate longer-term effects of pharmacological treatment of ADHD on children's health. We rely on a difference-in-differences strategy while exploiting Danish register-based panel data for children born in 1990-1999. We study effects of treatment initiated between ages...

This paper investigates pre-teenage effects of the choice of type of non-parental child care at age three (preschool relative to more informal family day care). We exploit a Danish panel data child survey merged with administrative records along with a pseudo-experiment that generates variation...
