We study the effects of access to a child home care allowance on parents' labor supply and childcare decisions, as well as their longer-term earnings trajectories and children's school performance. To establish causality, we exploit variation in the availability of the allowance over time and...

Women account for the majority of parental leave take-up, which is likely one of the major reasons for the gender gap in income and wages. Consequently, many countries exert effort to promote a more gender equal division of parental leave. Indeed, the last decades have seen an increase in...

We evaluate the effect of a preschool health intervention aimed at reducing infections through improved hygiene practices and training of the staff. The large-scale design enables us to study heterogeneous effects with respect to several child and preschool characteristics that are assumed to be...

The identification of average causal effects of a treatment in observational studies is typically based either on the unconfoundedness assumption or on the availability of an instrument. When available, instruments may also be used to test for the unconfoundedness assumption (exogeneity of the...

When a treatment unambiguously defines the treatment and control groups at a given time point, its effects are usually found by comparing the two groups' mean responses. But there are many cases where the treatment timing is chosen, for which the conventional approach fails.This paper sets up an...
