Using twenty-five policy variables, we investigate determinants of mobile phone/banking in 49 Sub-Saharan African countries with data for the year 2011. The determinants are classified into six policy categories, notably: macroeconomic, business/bank, market-related, knowledge economy, external flows and human development. The empirical evidence is based on contemporary and non-contemporary Quantile regressions. The following implications are relevant to the findings. First, mobile phone penetration is positively correlated with: (i) education, domestic savings, regulation quality and patent applications, especially at low initial levels of mobile penetration; (ii) bank density; (iii) urban population density and (iv) internet penetration. Second, the use of the mobile to pay bills is positively linked with: (i) trade and internet penetration, especially in contemporary specifications and (ii) remittances and patent applications, especially at low initial levels of the dependent variable. Third, using the mobile to send/receive money is positively correlated with: internet penetration and human development, especially in the contemporary specifications. Fourth, mobile banking is positively linked with: (i) trade in contemporary specifications; (ii) remittances and patent applications at low initial levels of the dependent variable and (iii) internet penetration and human development, with contemporary threshold evidence. The policy implications are articulated with incremental policy syndromes.
