A social analysis of the Red de Protección Social (RPS) in Nicaragua por Adato, Michelle, Roopnaraine, Terry, Álvarez, Fabiola Alvarado, Peña, Leticia Böttel, Castrillo, Gladys Meléndez

“…What is so important about CCTs is that first, they take a systematic approach to assuring a basic income safety net for the poor, rather than relying on more diffuse, indirect process of poverty reduction, e.g. through demand-driven infrastructure programs; and second, they aim to do more than just put short-term cash in people‘s hands—important as this aspect of safety nets is—but also to invest in the long-term human capital of future generations. …”

HIV/AIDS, Household Income, and Consumption Dynamics in Malawi por Masanjala, Winford H.

“…This is all the more troubling because, although in the past 15 years economists have attempted to systematically link AIDS and poverty and to test the strength of those linkages, the relationships among livelihoods, poverty, and the AIDS epidemic remains so complex that we still know little about the actual contribution of AIDS in explaining observed cases of persistent poverty and divergent economic fortunes in Africa. …”

“Did you control for rainfall?”: Geospatial weather data, measurement error and the consistency of farm model estimates in Ethiopia por Bisrat Gebrekidan, Chamberlin, Jordan

“…Yet guidance on which dataset to use, among the many available alternatives, has largely been lacking: while there have been some studies comparing rainfall data quality across alternative datasets, relative to some accuracy benchmark, there has not yet been systematic analysis of whether the choice of rainfall dataset may affect econometric model performance, or the estimation of other (non-rainfall) model parameters. …”
