Global access to preschool has increased dramatically yet preschool quality is often poor. We use a randomized controlled trial to evaluate two approaches to improving the quality of Colombian preschools. We find that the first, which was rolled out nationwide and provides additional resources...

Many children in developing countries grow up in unstimulating environments, leading to deficiencies in early years' developmental outcomes, particularly cognition and language. Interventions to improve parenting in the first 3 years of life have a clear impact on these outcomes, but the...

This paper estimates flexible child health production functions to investigate whether better water, sanitation and hygiene (WASH) practices make nutrition intake more productive for children aged 6-24 months. Using cohort data, with detailed information on nutrition intake and WASH...

Rajasthani women typically leave school early and marry young. We develop a novel discrete choice methodology using hypothetical vignettes to elicit average parental preferences over a daughter’s education and age of marriage, and subjective beliefs about the evolution of her marriage market...

We examine how the effects of incentivizing individuals to use healthcare depend on the capacity of the health system. We study a conditional cash transfer program (JSY) in India that paid women to give birth in medical facilities. We find that JSY doubled the number of deliveries for which the...

We study the relationship between child work and cognitive development in four Low and Middle Income Countries. We address a key weakness in the literature by including children’s full time-use vector in the analysis, which leads to different findings from previous studies which do not...

The large sibling correlations in risky behaviour between siblings raise the possibility that adolescents may directly influence the actions of their brothers or sisters. We assess the extent to which correlations in substance use and selling drugs are causal. Our identification strategy relies...

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children. We estimate production functions for cognitive and socio-emotional skills as a function of...

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children aged 12 to 24 months at baseline. We estimate the determinants of parents' material and time...

Instructional time is seen as an important determinant of school performance, but little is known about the effects of student absence. Combining historical records and administrative data for Swedish individuals born in the 1930s, we examine the impacts of absence in elementary school on...
