Mobile phone coverage and adoption has grown substantially over the past decade, primarily in sub-Saharan Africa. In the absence of public goods infrastructure in many countries, mobile phone technology has the potential to reduce communication and transaction costs and improve access to information, goods and services, particularly for remote rural populations. Research suggests that mobile phone coverage has had positive impacts on agricultural and labor market efficiency in certain countries, but empirical microeconomic evidence is still limited. This paper presents the results of several mobile phone-related field experiments in sub-Saharan Africa, whereby mobile phones have been used for learning, money transfers and civic education programs. These experiments suggest that mobile phone technology can result in reductions in communication and transaction costs, as well as welfare gains, in particular contexts. Nevertheless, mobile phone technology cannot serve as the “silver bullet” for development, and careful impact evaluations of mobile phone development projects are required. In addition, mobile phone technology must work in partnership with other public good provision and investment to achieve optimal development outcomes.
