Teachers are the most fundamental input of students' learning. For this reason, developing teaching skills is a policy priority for most governments around the world. We experimentally evaluate the effectiveness of "Let's All Learn to Read," a one-year professional development program that...

Canonical human capital theories posit that education, by enhancing worker skills, reduces the likelihood that a worker will be laid-off during times of economic change. Yet, this has not been demonstrated causally. We link administrative education records from 1987 through 2002 to nationally...

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...

To study the causal impact of oil royalties on human capital, we exploit quasi-experimental variation arising from a law in Ecuador that transfers resources to municipalities regardless of their oil-producing status. We find that royalties increase the likelihood of students completing primary...

In 1997, the Mexican government designed the conditional cash transfer program Progresa, which became the worldwide model of a new approach to social programs, simultaneously targeting human capital accumulation and poverty reduction. A large literature has documented the short and medium-term...

Many school systems today are trying to attract top college graduates into teaching, but little is known about what dissuades this target group from entering the profession. This study randomly assigned applicants for a highly-selective alternative pathway into teaching in Argentina either to a...

A growing body of research argues that early adverse experiences have lasting effects not only on later health outcomes, but also on human capital accumulation. This paper investigates the persistent effect of negative shocks early in life on children's health and cognitive outcomes, and...

This paper examines the causal link between early childhood nutrition and cognition, applying instrumental variables to sibling-differences for a sample of pre-school aged Peruvian children. Child-specific shocks in the form of food price changes and household shocks during the critical...

We study the impact on learning of a child's rank in the classroom using a unique experiment from Ecuador. Within each school, students were randomly assigned to classrooms in every grade between kindergarten and 6th grade.Therefore, two students with the same ability can have different...

This paper presents the results of an impact evaluation, with an experimental design, which estimates the effect on learning math of a remote tutoring program offered to girls and boys aged 9-14 years in three departments of El Salvador. The program used low-tech interventions such as text...
