In-service teacher training aims to improve the supply of public education. A randomized experiment was conducted in Mexico to test whether teacher training could increase teacher efficiency in public secondary schools. After seven and a half months of exposure to a trained teacher, students...

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...

I review the evidence on access to water and sanitation infrastructure and child outcomes In Latin America. I show that there are large differences in access across countries and, within countries, between households living in urban and rural areas. Many papers in the public health literature...

Valuing a change in the risk of death is a key input into the calculation of the benefits of environmental policies that save lives. Typically such risks are monetized using the Value of a Statistical Life (VSL). Because the majority of the lives saved by environmental policies are those of...

This paper examines factors that may influence the estimates of the Value of a Statistical Life obtained from contingent valuation surveys that elicit the willingness to pay (WTP) for mortality risk reductions. We examine the importance of distributional assumptions, the choice of the welfare...

This paper attempts to identify the climatic effect on birth outcomes in Brazil and, thus, to predict the potential impact of climate change. Panel data models indicate that excess and lack of rainfall have the most important harmful effects on newborns' health; temperature stresses and low...

This paper uses data from the Global School-based Student Health Survey to investigate the prevalence of health risk behaviors, in particular substance use, risky sexual behavior, and violence among adolescents in 15 Latin American and Caribbean countries. Using logit regressions and...

We implement a mixed method approach that combines a randomized controlled trial and qualitative data collection to assess whether, and if so how, behavioural change can be sustained. We do so in the context of Pakistan’s national sanitation strategy to combat open defecation, Community-Led...

While effective preventive measures against COVID-19 are now widely known, many individuals fail to adopt them. This paper provides experimental evidence about one potentially important driver of compliance with social distancing: social norms. We asked each of 23,000 survey respondents in...

In this paper, we test whether promoting digital government tools increases the take-up of an important public health prevention service: cervical cancer screening. We implemented an at-scale field experiment in Uruguay, randomly encouraging women to make medical appointments with a digital...
