Cellular technologies have become increasingly important in the developing world; infrastructure for mobile networks has expanded dramatically over the past two decades giving access to remote areas without previous phone service. Despite this expansion, relatively little is known about the correlates of the rollout of cellular phone networks or the performance of these networks. Since the rollout of cellular networks has been largely spearheaded by an active private sector in telecommunications, how demand-side and cost-side factors affect the timing of rollout and quality of network service is of particular interest. In this paper we use new data to estimate the correlates of cellular phone access and network performance across rural areas of Malawi. We compile a dataset which combin...

The spread of the HIV/AIDS epidemic is still fueled by ignorance in many parts of the world. Filling in knowledge gaps, particularly between men and women, is considered key to preventing future infections and to reducing female vulnerabilities to the disease. However, such knowledge is arguably only a necessary condition for targeting these objectives. In this paper, we describe the extent to which HIV/AIDS knowledge is correlated with less risky sexual behavior. We ask: even when there are no substantial knowledge gaps between men and women, do we still observe sex-specific differentials in sexual behavior that would increase vulnerability to infection? We use data from two recent household surveys in Botswana to address this question. We show that even when men and women have very simil...
