|August 2019||Preschool Quality and Child Development|
with Alison Andrew, Orazio Attanasio, Raquel Bernal, Lina Cardona Sosa, Sonya Krutikova: w26191
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 for materials and new staff, did not benefit children’s development and, unintentionally, led teachers to reduce their involvement in classroom activities. The second approach additionally trains teachers to improve their pedagogical methods. We find this addition offset the negative effects on teacher behavior, improved the quality of teaching and raised children’s cognition, language and school readiness.
|September 2018||Early Stimulation and Nutrition: The Impacts of a Scalable Intervention|
with Orazio Attanasio, Helen Baker-Henningham, Raquel Bernal, Costas Meghir, Diana Pineda: w25059
This paper evaluates the effects of the implementation of a structured early stimulation curriculum combined with a nutritional intervention through public large-scale parenting support services for vulnerable families in rural Colombia, known as FAMI, using a clustered randomized controlled trial. We randomly assigned 87 towns in rural areas to treatment and control and 1,460 children younger than 1 year of age were assessed at baseline. The interventions were also complemented with training, supervision and coaching of FAMI program facilitators. We assessed program effects on children’s nutritional status, and on cognitive and socio-emotional development; as well as on parental practices. The interventions had a positive and significant effect on a cognitive development factor based on t...
|February 2015||Estimating the Production Function for Human Capital: Results from a Randomized Control Trial in Colombia|
with Orazio Attanasio, Sarah Cattan, Emla Fitzsimons, Costas Meghir: w20965
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 investments in these children and evaluate the impact of the treatment on such investments. We then estimate the production functions for cognitive and socio-emotional skills. The effects of the program can be explained by increases in parental investments, emphasizing the importance of parenting interventions at an early age.
