Using partial linear regression model, a dataset from the International Monetary Fund (IMF), World Bank National Economic data and the mobile banking data were explored from GSMA for the period between 2011 and 2017 were analyzed. A negative correlation was found between the variables and growth as well as financial development, however, a positive relationship was established between financial development and economic development.
