We study the socio-economic gradient of child development on a representative sample of low- and middle-income children aged 6-42 months in Bogota, using the Bayley Scales of Infant Development, a high quality test based on direct observation of the child's abilities. We find a statistically...

This discussion paper was presented in the seminar "First Meeting of the Social Policy Monitoring Network: Conditional Cash-Transfer Programs". In this paper the authors use an economic model to analyze data from a major randomized social experiment, namely PROGRESA in Mexico, and to evaluate...

Presents information about opportunity cost of attendance to school, touching on issues of the proper dimensioning of cash subsidies, the adequacy of the conditionality and operational issues associated with conditional cash transfer (CCT) programs. It then analyzes the challenge of increasing...

In this paper, we use an economic model to analyse data from a major randomized social experiment, namely PROGRESA in Mexico, and to evaluate its impact on school participation. We show the usefulness of using experimental data to estimate a structural economic model as well as the importance of...

Using the infrastructure of a national welfare program we implemented the integrated early child development intervention on a large scale and showed its potential for improving children’s cognitive development. We found no effect of supplementation on developmental or health outcomes....

Using data from an experiment conducted in 70 Colombian communities, we investigate who pools risk with whom when trust is crucial to enforce risk pooling arrangements. We explore the roles played by risk attitudes and social networks. Both theoretically and empirically, we find that close...
