Project Description

This project will use a dataset, a log of all phone calls and transfers made over the Rwandan phone network over the past five years, to better understand how mobile banking is being used, and what the potential impacts on its users will be. By combining this dataset with data from structured phone interviews, the project seeks a deeper understanding of (i) how mobile banking fits into the existing landscape of formal and informal lending, (ii) how existing social networks facilitate the flow of mobile money; and (iii) how different subgroups of the population differentially benefit from access to mobile banking.
