This paper uses a dataset from Tanzania that contains information on consumption, income and income shocks within and across family networks. A unique feature of this data is that it contains data on the degree of information existing between each pair of households within family networks.

We study risk sharing within these networks and explore whether the rejection of perfect risk sharing that we observe can be related to imperfections in the information network members have about each.

|August 2019||Preschool Quality and Child Development|
with Alison Andrew, Orazio Attanasio, Raquel Bernal, Lina Cardona Sosa, Marta Rubio-Codina: 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.
