Mobile money, a technology-driven innovation in financial services, has profoundly penetrated the financial landscape in Sub-Saharan Africa, including banks. Yet, besides anecdotal evidence, little is known about whether mobile money adoption enhances or worsens bank performance.Combining hand-collected data with balance sheet data from Bankscope for a panel of 170 financial institutions over the period 2009-2015, we find a strong positive and significant relationship between the time elapsed since banks' adoption of mobile money and their performance considering an array of proxies of bank profitability, efficiency and stability. In further investigations, we show how bank specialization and size alter such an association. Our results are robust to using instrumental variables, controlling for bank and macro level confounding factors, bank fixed effects and considering alternative measures of bank performance and mobile money adoption. Furthermore, we show that enhanced income diversification and broadened access to deposits are possible channels through which banks involved in mobile money improve their performance. Overall, our findings highlight the bright side of cooperation between banks and mobile network operators in the provision of mobile money. (JEL Classification G02, G21, G23

We examine prospects for a monetary union in the East African Community (EAC) by developing a stylised model of policymakers' decision problem that allows for uncertain benefits derived from monetary, financial and fiscal stability and then calibrating the model for the EAC for the period 2003–10. When policymakers properly allow for uncertainty, none of the countries wants to pursue a monetary union based on either monetary or financial stability grounds, and only Rwanda might favour it on fiscal stability grounds; we argue that robust institutional arrangements assuring substantial improvements in monetary, financial and fiscal stability are needed to compensate.

Access to and usage of formal financial services are important determinants of financial inclusion and yet, informal mechanisms still dominate the financial system in developing countries. In this context, the purpose of our paper is to investigate how the growing effort to harness mobile money may play a role to overcome barriers that prevent people to access formal financial services. Using a unique dataset obtained from an individual-level survey conducted in Burkina Faso, we explore the interplay between mobile money innovation as a deposit instrument and pre-existing formal and informal financial instruments. Our main findings show that, overall, the use of mobile money is not associated with deposits using formal and/or informal financial instruments. However, a closer investigation reveals suggestive evidence that it increases the probability of participants in informal mechanisms to make deposits in a bank account. Moreover, considering disadvantaged groups, we find for women, irregular income and less educated individuals that mobile money may increase their probability to make deposits in a bank and/or credit union accounts. Given the low access to formal financial services in developing countries, our findings taken together indicate how the increasing adoption of mobile money may act as a stepping-stone towards financial inclusion.
