This paper studies a model where student effort and talent interact with parental and teachers' investments, as well as with school system resources. The model is rich, yet sufficiently stylized to provide novel implications. It can show, for example, that an improvement in parental outside...

CCT programs have become the anti-poverty program of choice in many developing countries. Numerous evaluations, often based on rigorous experimental designs, leave little doubt that such programs can increase enrollment and grades attained--in the short term. But evidence is notably lacking on...

This paper reports the results of an experiment with secondary school students designed to improve their ability to reason, argument, and communicate using mathematics. These goals are at the core of many educational reforms. A structured pedagogical intervention was created that fostered a more...

While decreasing inequality is generally considered desirable, and there is a growing understanding of which policies do and do not promote equality, much less is known regarding why these policies are adopted to varying degrees of intensity in different times and places. To explain this...

This paper presents results from a randomized control trial in which approximately 1,000 OLPC XO laptops were provided for home use to children attending primary schools in Lima, Peru. The intervention increased access and use of home computers, with some substitution away from computer use...

Evidence on the impacts of a large-scale expansion in public preprimary education is limited and mostly circumscribed to high and middle-income countries. This paper estimates the effects of such an expansion on progression in primary school in rural communities of Guatemala. Combining...

Many developing countries have adopted the market approach for expanding the supply of child care, but little is known about the economic behavior of independent providers. This paper draws on uniquely rich administrative data on child care centers and their inputs from São Paulo to examine the...

Although many countries are aggressively implementing the One Laptop per Child (OLPC) program, there is a lack of empirical evidence on its effects. This paper presents the impact of the first large-scale randomized evaluation of the OLPC program, using data collected after 15 months of...

This paper analyzes the effects of increased shared computer access in secondary schools in Peru. Administrative data are used to identify, through propensity-score matching, two groups of schools with similar observable educational inputs but different intensity in computer access. Extensive...

This paper examines whether an expansion in the supply of public preschool crowds out private enrollment, using rich data for municipalities in Brazil from 2000-2006, where federal transfers to local governments change discontinuously with given population thresholds. Results from a...
