Access to mobile money services is shown to have a significant impact on economic activity. Areas with access to mobile money services grow faster, especially when they are initially richer, urban, and connected to roads and to banks. The heterogeneity of the the short- and long-run effects of railroads on individual and local development in Nigeria is found to be substantial.
