Beyond the individual
Activity of daily living (ADL) limitations, such as difficulty walking or dressing, are increasing as populations age and experience more chronic conditions. To understand the scope of ADLs and make interventions more effective, it is important to examine ADLs beyond the individual to other levels and contexts, such as the household. Thus, using household and individual level survey data in India, we assess how household ADLs relate to the mental…
More Powerful Cluster Randomized Control Trials
Balanced experimental designs, in which the number of treatment and control units are the same, do not maximize power subject to a cost constraint when treatment units are more expensive than control ones. Despite this, such balanced designs are the norm in economics. This paper describes methods to optimally choose the number of treatment and control clusters, and the number of units within treatment and control clusters, allowing for full flexi…
Incentivizing Demand for Supply-Constrained Care
If overcrowding harms health care quality, the impacts of encouraging more people to use services are not obvious. Impacts will depend on whether marginal entrants benefit and whether they benefit enough to offset the congestion externalities imposed on inframarginal users. We develop a general-equilibrium model that formalizes these ideas. We examine them empirically by studying JSY, a program in India that paid women to give birth in medical fa…
Spillovers of Community-Based Health Interventions on Consumption Smoothing
Community-based group interventions are a cost-effective way of delivering programs in low-income settings. Design features may influence behaviors beyond those targeted by the intervention. This paper studies spillover effects of a participatory community health intervention in rural Malawi, implemented through a cluster randomized control trial, on an untargeted outcome: consumption smoothing after crop losses. While crop losses reduce consumpt…
The effects of the transition from home-based childcare to childcare centers on children’s health and development in Colombia
Colombia's national early childhood strategy launched in 2011 aimed at improving the quality of childcare services offered to socio-economically vulnerable children, and included the possibility that children and their childcare providers could transfer from non-parental family daycare units to large childcare centers in urban areas. This study seeks to understand whether the offer to transfer and the actual transfer from one program to the other…
Group Size and the Efficiency of Informal Risk Sharing
This paper studies the relationship between group size and informal risk sharing. It shows that under limited commitment with coalitional deviations, this relationship is theoretically ambiguous. It investigates this question empirically using data on sibship size of household heads and spouses from rural Malawi, exploiting a social norm among the main sample ethnic group to define the potential risk sharing group. We uncover evidence of worse ri…
Nutrition, information and household behavior
Incorrect knowledge of the health production function may lead to inefficient household choices and thereby to the production of suboptimal levels of health. This paper studies the effects of a randomized intervention in rural Malawi that, over a six-month period, provided mothers of young infants with information on child nutrition without supplying any monetary or in-kind resources. A simple model first investigates theoretically how nutrition …
Frequency of HIV-testing and factors associated with multiple lifetime HIV-testing among a rural population of Zambian men
Although men's levels of ever-testing for HIV have increased, strategies need to increase the lifetime frequency of HIV-testing among men at continued risk of HIV-infection
Community Nurseries and the Nutritional Status of Poor Children. Evidence from Colombia
We use two different data sets and three different instruments to estimate the impact of a long‐established pre‐school nursery programme on children's nutritional status. We use variables related to cost (fee, distance to the nursery) and programme availability (capacity of the programme in the town) as instruments. One of our data sets is representative of very poor individuals living in rural areas of Colombia, while the other focuses in urban …

Early Childhood Stimulation Benefits Adult Competence and Reduces Violent Behavior
OBJECTIVE: An estimated 178 million children younger than 5 years in developing countries experience linear growth retardation and are unlikely to attain their developmental potential. We aimed to evaluate adult benefits from early childhood stimulation and/or nutritional supplementation in growth-retarded children. METHODS: In Kingston, Jamaica, 129 growth-retarded children aged 9 to 24 months took part in a 2-year trial of nutritional supplemen…
