Results-based aid (RBA) models link funds to outcomes, rather than paying for inputs. Despite their theoretical appeal and recent adoption by donors and multilateral development banks, there is limited empirical evidence supporting this form of aid for national governments. We estimate the...

We study the effects of conditional cash transfers to pregnant women on stillbirths and child survival in Bolivia. Payments are conditional on compliance with medically recommended prenatal care and skilled birth attendance. At a value equivalent to just 1% of monthly household consumption, the...

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...

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...

This article relies on a large-scale field experiment in Mexico to measure the effects of two ability-grouping models (tracking and heterogeneous/bimodal groups) on student learning outcomes during middle school. Both strategies yielded an average learning gain of 0.08 of a standard deviation....

Tailoring instruction to each student's needs can produce significant learning gains. However, few programs have successfully implemented this approach. In this paper, we present the results of a randomized evaluation of a program that uses an inquiry with an individualized scaffolding approach...

The effects of early life circumstances on cognitive skill formation are important for later human capital development, labor market outcomes and well-being. In this paper, we test the hypothesis that the first 1,000 days are the critical window for both cognitive skill formation and physical...

This paper provides empirical evidence on the causal effects that upgrading slum dwellings has on the living conditions of the extremely poor. In particular, we study the impact of providing better houses in situ to slum dwellers in El Salvador, Mexico and Uruguay. We experimentally evaluate the...

This paper examines how rural households cope with climate change related rainfall shocks by re-allocating children's time between domestic activities and school attendance. Households affected by an unanticipated rainfall shock face an inter-temporal trade-off between current household income...
