While there is a large literature linking the expansion of mobile money services to improved economic outcomes, there are only a few studies in select countries that study its potential political implications. This paper addresses this gap by investigating the relationship between national-level mobile money activity and individual-level corruption in Africa. Using data from up to 98,000 individuals across 31 African countries, we use repeated cross-sectional surveys and multilevel regression models to examine how national mobile money activity correlates with individual bribe payments over time. In a novel contribution, our findings reveal a robust association between higher mobile money activity and reduced bribe payments for public services at the individual level. We argue that the growing prevalence of mobile money likely enhances transparency and increases the costs of engaging in corruption. Additionally, by enabling direct and digital payment of service fees, mobile money may allow users to bypass intermediaries and government officials who might otherwise solicit bribes. These findings underscore the potential of mobile money as a tool for promoting transparency and improving governance systems.
