Movements in and out of poverty are of core interest to both policymakers and economists. Yet the panel data needed to analyze such movements are rare. In this paper, the authors build on the methodology used to construct poverty maps to show how repeated cross-sections of household survey data...

Consistent adoption of preventive health behaviors could save many lives, but we do not understand how to create consistent adoption. For example, low-cost point-of-use (POU) water treatment technologies such as chlorine and filters can substantially reduce diarrheal disease, a leading cause of...

Convincing people to adopt preventive health behaviors consistently is difficult, yet many lives could be saved if we understood better how to do so. For example, low-cost point-of-use (POU) technologies such as chlorine and filters can substantially reduce diarrheal disease (Clasen et al....

Uptake of safe water products remains low, in spite of modest cost. We experimented with a sales offer that combined a free trial and rent-to-own payments for durable filters. Purchase rates doubled under this sales offer to 31% compared to a traditional lump-sum sales contract. To lower...

Increases in formal sector lending among the poor have created a need for credit information systems that provide potential lenders with borrower information. In this article we present fixed-effects estimations that attempt to measure the effect of a newly implemented credit information system...

Tracking poverty is predicated on the availability of comparable consumption data and reliable price deflators. However, regular series of strictly comparable data are only rarely available. Price deflators are also often missing or disputed. In response, poverty prediction methods that track...
