Young children are thought to be vulnerable to separation from the primary caregiver/s. This raises concern about whether early child care enrollment may harm children's development. We use child care assignment lotteries to estimate the effect of child care starting age on early cognitive...

According to school entry regulations in most countries, the composition of school entrance cohorts is determined by a fixed cutoff date. This procedure creates inter-cohort differences in age and development which can severely influence educational trajectories. Developmental examinations at...

While recent studies mostly find that attending child care earlier improves the skills of children from low socio-economic and non-native backgrounds in the short-run, it remains unclear whether such positive effects persist. We identify the short- and medium-run effects of early child care...

We estimate effects of child care center staff composition on early child development. During the years our data covers, child care centers in Oslo were oversubscribed, and child care slots were allocated through a lottery. This allow us to explore how staff education, experience and stability,...

We examine the relationship between parental ethnic identity and cognitive development in ethnic minority children. This aspect of parental identity may shape children's cognitive outcomes through a direct influence on parenting behaviour, or by mediating parental access to social resources....

In this paper we use a parental leave reform directed towards fathers to identify the causal effects of paternity leave on children's and parents' outcomes. We document that paternity leave causes fathers to become more important for children's cognitive skills. School performance at age 16...

In this paper we explore the impact of birth weight on children's cognitive and behavioural outcomes using data from the UK Millennium Cohort Study. In order to deal with the endogeneity of birth weight we use an estimator based on the eliminant method. When coupled with ordinary least squares,...
