I examine the changes in poverty and inequality in South Africa during the first 5 years following the end of the apartheid era. First, I construct new, comparable consumption aggregates for 1995 and 2000. Second, using the "cost-of basic-needs" approach, I derive lower-bound (R322, in South...

An extensive multi-disciplinary literature examines the effects of learning one’s HIV status on subsequent risky sexual behaviors. However, many of these studies rely on nonexperimental designs; use self-reported outcome measures, or both. In this study, we investigate the effects of a...

In this paper, the authors investigate the effect of positive income shocks on the mental health of adolescent girls using experimental evidence from a cash transfer program in Malawi. They find that the provision of monthly cash transfers had a strong beneficial impact on the mental health of...

Despite their explicit focus on reaching the poor, many community driven development (CDD) projects have been found to be only mildly pro-poor in their funding allocations. This paper presents evidence of an explanation that has been overlooked in the CDD literature to date: the requirement that...

Recent evidence suggests that conditional cash transfer programs for schooling are effective in raising school enrollment and attendance. However, there is also reason to believe that such programs can affect other outcomes, such as the sexual behavior of their young beneficiaries. Zomba Cash...

This paper formalizes the design of experiments intended speciï¬cally to study spillover effects. . By ï¬rst randomizing the intensity of treatment within clusters and then randomly assigning individual treatment conditional on this cluster-level intensity, a novel set of treatment effects...

Income differences arise from many sources. While some kinds of inequality, caused by effort differences, might be associated with faster economic growth, other kinds, arising from unequal opportunities for investment, might be detrimental to economic progress. We construct two new metadata...
