Mobile phones have been one of the most rapidly adopted technologies ever introduced in the developing world. With multiple uses such as voice, SMS, and access to the internet, mobile phones produce diverse economic and social benefits. CGD research has explored the development applications, as well as how mobile phones can be used to reliably gather data on citizens’ preferences and their ability to access basic services.
This paper presents short-term results from an experiment randomizing the promotion and registration of a mobile savings account among women microentrepreneurs in Tanzania, with and without business training. Six months post-intervention, the results show that women save substantially more through the mobile account, and that the business training bolstered this effect.
In rural areas of developing countries, education programs are often implemented through community teachers. While teachers are a crucial part of the education production function, observing their effort remains a challenge for the public sector. This paper tests whether a simple monitoring system, implemented via the mobile phone, can improve student learning as part of an adult education program.
In this project, we analyzed whether mobile phone-based surveys are a feasible and cost-effective approach for gathering statistically representative information in four low-income countries (Afghanistan, Ethiopia, Mozambique, and Zimbabwe).
Over 60 percent of Africans have access to a cell phone, a simple technology that many believe will fundamentally change the dynamics of agricultural markets, banking, and government service delivery. In a new paper, Jenny Aker and Isaac Mbiti separate the hype from the reality.
Over 755 million adults worldwide are unable to read and write in any language. Yet the widespread introduction of information and communication technology offers new opportunities to provide standardized distance education to underserved illiterate populations in both developed and developing countries.
This paper reports on the first randomized evaluation of a cash transfer program delivered via mobile phone. The trial households in targeted villages monthly cash transfers and finds that the mobile phone–based program saves costs and has greater benefits for recipients.

The results of a randomized evaluation of a mobile phone education program (Project ABC) in Niger suggest that simple and relatively cheap information and communication technology can serve as an effective and sustainable learning tool for rural populations.

The days of pushing priorities, pet projects, or expat consultants on countries are coming to a close. Connected and increasingly empowered individuals are demanding a greater say in setting priorities, designing and implementing programs, and assessing whether projects have achieved their desired results. For those agencies that recognize this trend, the question is how to meaningfully and cost effectively engage citizens in real time.
