Article
Full-text available
We document substantial variation in the effects of a highly-effective literacy program in northern Uganda. The program increases test scores by 1.4 SDs on average, but standard statistical bounds show that the impact standard deviation exceeds 1.0 SD. This implies that the variation in effects across our students is wider than the spread of mean e...
Article
Temptation plays a key role in theoretical work on spending and saving in developing countries. The limited empirical evidence on its importance, however, suggests that cash transfers do not induce increases in temptation spending. This paper expands the evidence base by studying the effect of randomized exposure to temptation on spending decisions...

Health behaviors are plagued by self-control problems, and commitment devices are frequently proposed as a solution. We show that a simple alternative works even better: appointments. We randomly offer HIV testing appointments and financial commitment devices to high-risk men in Malawi. Appointments are much more effective than financial commitment...
Article
Full-text available
We study a simple savings scheme that allows workers to defer receipt of part of their wages for three months at zero interest. The scheme significantly increases savings during the deferral period, leading to higher postdisbursement spending on lumpy goods. Two years later, after two additional rounds of the savings scheme, we find that treated wo...

Full-text available
Directly eliciting individuals' subjective beliefs via surveys is increasingly popular in social science research, but doing so via face-to-face surveys has an important downside: the interviewer's knowledge of the topic may spill over onto the respondent's recorded beliefs. Using a randomized experiment that used interviewers to implement an infor...
Preprint
This paper demonstrates the acute sensitivity of education program effectiveness to the choices of inputs and outcome measures, using a randomized evaluation of a mother-tongue literacy program. The program raises reading scores by 0.64SDs and writing scores by 0.45SDs. A reduced-cost version instead yields statistically-insignificant reading gains...
Preprint
This paper studies workplace peer effects by randomly varying work assignments at a tea estate in Malawi. We find that increasing mean peer ability by 10 percent raises productivity by 0.3 percent. This effect is driven by the responses of women. Neither production nor compensation externalities cause the effect because workers receive piece rates and...

Article
Full-text available
People in developing countries sometimes desire deferred income streams, which replace more-frequent income flows with a single, later lump sum. We study the effects of short-term wage deferral using a randomized experiment with participants in a temporary cash-for-work program. Workers who are assigned to lump-sum payments are five percentage poin...
Article
Full-text available
Economics is limited by the fact that it is not an experimental science: our ability to experimentally test models of economic behavior is constrained by logistics and ethics. However, this view has been reshaped by the credibility revolution of the last two decades and the recent growth of randomized trials in developing countries, which have show...
Article
Full-text available
Objectives: Despite medical evidence that female-to-male oral sex (fellatio) carries a lower risk for HIV transmission than unprotected vaginal intercourse, little research exists on the practice of fellatio in Africa. The objective of this study was to document the prevalence of oral sex in Malawi, and to provide the first evidence on factors asso...
Article
Full-text available
Despite the efforts of educators, public health officials, and HIV/AIDS prevention experts, condom promotion has failed to stop the HIV epidemic in most of sub- Saharan Africa and most researchers and policy makers have focused on risk reductions for interventions for penetrative sex. We consider another HIV prevention option: female-to-male oral s...

Episode grouper software offers a potential framework for developing important components of a pay-for-performance system for healthcare providers. If the costs for treating health conditions can be computed, then policymakers can in principle benchmark different providers' cost distributions and reward the most efficient. This article applies two...
