The Green Revolution bolstered agricultural yields and rural well-being in Asia and Latin America, but bypassed sub-Saharan Africa. We study the first randomized controlled trial of a government-implemented input subsidy program (ISP) in Africa. A temporary subsidy for Mozambican maize farmers...

We report the results of a randomized experiment testing impacts of subsidies for modern agricultural inputs in rural Mozambique. One-time provision of a voucher for fertilizer and improved seeds leads to substantial increases in fertilizer use, which persist through two subsequent agricultural...

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...

This paper uses the data on child development collected around the evaluation of a nursery program to estimate the details of the process of human development. We model development as made of three latent factors, reflecting health, cognitive and socio-emotional skills. We observe children from...

Colombia's unemployment rate rose to 20% during the late 1990s from less than 8% in 1994. This paper argues that this has been the result of high non-wage labor costs embodied in the legislation. The estimated own-wage labor demand elasticity is around 0.5, which implies that a reduction in...

Global access to preschool has increased dramatically, yet preschool quality is often poor and evidence on how to improve it is scarce. We worked with the government of Colombia to implement a largescale randomized controlled trial evaluating two interventions targeting the quality of public...

Many poor households in developing countries are liquidity-constrained. As a result, they may under-invest in the human capital of their children. We provide new evidence on the long-term (10-year) effects of cash transfers using data from Ecuador. Our analysis is based on two separate sources...

How important are subsistence concerns in a family's decision to send a child to work? We consider this question in Ecuador, where poor families are selected at random to receive a cash transfer that is equivalent to 7 percent of monthly expenditures. Winning the cash transfer lottery is...
