Exploiting a rich panel data child survey merged with administrative records along with a pseudo-experiment generating variation in the take-up of pre-school across municipalities, we provide evidence of the effects on non-cognitive child outcomes of participating in large scale publicly...

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...

This is one of the few studies that estimates the effects of type of childhood care on academic achievement at higher grade levels by linking day care registers and educational registers. We use entire birth cohorts of ethnic Danish children, enrolled in either center based day care or family...

This paper uses register based data covering the entire population of Danish children enrolled in preschool in 2006-2007 to investigate whether the gender composition of preschool staff members affects the timing of school start and subsequent academic performance. To estimate effects of the...
