We evaluate impacts heterogeneity of an Early Childhood Intervention, with respect to the Educational Attainment Polygenic Score (EA4 PGS) constructed from DNA data based on GWAS weights from a European population. We find that the EA4 PGS is predictive of several measures of child development,...

We evaluate impacts heterogeneity of an Early Childhood Intervention in Colombia, with respect to the Educational Attainment Polygenic Score (EA4 PGS) constructed from DNA data based on GWAS weights from a European population. We find that the EA4 PGS is predictive of several measures of child...

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...

Nearly 200 million children under five in low- and middle-income countries face developmental deficits, even as access to early childhood services expands. We present evidence from a large-scale randomized controlled trial (N=3,131 children in 201 schools) in Nepal's government system testing...

Nearly 200 million children under five in low- and middle-income countries face developmental deficits despite growing access to early childhood services. We report evidence from a randomized controlled trial (N=3,131 children in 201 schools) in Nepal's government system that tested three models...

Play during early childhood is key to stimulating children's physical, social, emotional, and cognitive development. However, research on play-based learning is largely limited to high-income countries, and little is known about the use of hybrid interventions (which combine in-person and remote...

In this article we experimentally evaluate Colombia's Think Equal program, which teaches socioemotional skills to children ages 3 to 6. Given the context of COVID-19, the original design was adapted as a hybrid model, alternating in-person and remote instruction and engaging families in the...

This paper investigates the causal impact of a randomized video intervention designed to study the determinants of parental time investments in early childhood among low-income parents. We designed and screened a video that provided information and conveyed persuasive messages about the...
