Three large new trials of unprecedented scale and cost, which included novel factorial designs, have found no effect basic water, sanitation hygiene (WASH) interventions on childhood stunting, only mixed effects diarrhea. Arriving at the inception United Nations’ Sustainable Development Goals, bold target safely managed for all by 2030, these results warrant attention researchers, policy-makers practitioners. Here we report conclusions an expert meeting convened World Health Organization...
Helping the poor invest in sanitation Almost a third of world's people do not have access to hygienic latrines. Improving and increasing use latrines would reduce deaths health caused by diarrheal disease. Guiteras et al. tested relative benefits supplying information, offering financial subsidy purchasers latrines, or availability for purchase. Providing worked best: Nonsubsidized households were more likely purchase when other their village subsidized. Science , this issue p. 903
We use the Becker-DeGroot-Marschak (BDM) mechanism to estimate willingness pay (WTP) for and heterogeneous impacts of clean water technology through a field experiment in Ghana. Although WTP is low relative cost, demand inelastic at prices. Short-run treatment effects are positive throughout distribution. After 1 year, benefits both increasing WTP, with negative on low-WTP households. Combining estimated households’ implies valuations health much smaller than typically used by policy makers....
Low willingness to pay (WTP) for environmental quality in developing countries is a key research question economics. One explanation that missing credit markets may suppress WTP improvements require large up-front investments. We test the impact of microloans on hygienic latrines via randomized controlled trial 30 villages rural Cambodia. find microcredit dramatically raises improved latrines, with 60% households Financing arm willing purchase at an unsubsidized price, relative 25%...
A burgeoning “Climate-Economy” literature has uncovered many effects of changes in temperature and precipitation on economic activity, but made considerably less progress modeling the other associated phenomena, like natural disasters. We develop new, objective data floods, focusing Bangladesh. show that rainfall self-reported exposure are weak proxies for true flood exposure. These allow us to study adaptation, giving accurate measures both long-term averages short term variation This is...
Poor water quality and sanitation are leading causes of mortality disease in developing countries. However, interventions providing toilets rural areas have not substantially improved health, likely because incomplete coverage low usage. This paper estimates the impact an integrated improvement program India that provided household-level connections, latrines, bathing facilities to all households approximately 100 villages. The suggest intervention was effective, reducing treated diarrhea...
Comprehensive evaluation requires tracking indirect effects of interventions, such as politicians and constituents reacting to the arrival a development program.We study political economy responses large scale intervention in Bangladesh, where 346 communities consisting 16,600 households were randomly assigned control, information or subsidy treatments encourage investments improved sanitation.In one leaders' role program allocation was not clear constituents, leaders react by spending more...
Lack of access to clean water is among the most pressing environmental problems in developing countries, where diarrheal disease kills nearly 700,000 children per year. While inexpensive and effective practices such as chlorination hand washing with soap exist, efforts motivate their use by emphasizing health benefits have seen only limited success. This paper measures effect messages appealing negative emotions (disgust at consumption human feces) social pressure (shame being consuming on...
Addressing public health externalities often requires community-level collective action. Due to social norms, each person's sanitation investment decisions may depend on the of neighbors. We report a cluster randomized controlled trial conducted with 19,000 households in rural Bangladesh where we grouped neighboring and introduced (either financial or recognition) rewards joint liability component for group, asked group member make private pledge maintain hygienic latrine. The reward has...
Domestic animals have been associated with enteric infections in young children and can also be carriers of respiratory viruses. We conducted a cross-sectional assessment health outcomes aged < 5 years animal presence among 793 rural households Uganda. recorded the 2-week prevalence diarrhea children, number cows, poultry, sheep/goats, pigs household. used generalized linear models robust standard errors to estimate ratio (PR) for owning above- versus below-median animals. unadjusted...
In many randomized trials, subjects enter the sample sequentially. Because covariates for all units are not known in advance, standard methods of stratification do apply. We describe and assess method D A -optimal sequential allocation ( Atkinson, 1982 ) balancing across treatment arms. provide simulation evidence that can substantial improvements precision over commonly employed alternatives. also our experience implementing a field trial clean water handwashing intervention Dhaka,...
