While several comparable countries in sub-Saharan Africa have seen a significant increase in financial inclusion, mainly driven by digital financial services, Ethiopia still performs poorly. Even digital payment and transfer services, which lower-income and less literate segments of the population could benefit from, are rarely used. Given the low development level of Ethiopia, numerous supply and demand factors could explain this disappointing outcome. The authors use a decision tree framework to isolate and analyze potential constraints to find which are bindingthat is, which constraints limit the expansion of digital payment services in Ethiopia. Our analysis indicates that supply-side problems are pervasive, and we find that competition problems in the essential digital infrastructure market and in the financial sector are responsible for the inadequate provision of digital payment services in Ethiopia.
