The concept of Social Media is top of the agenda for many business executives today. Decision makers, as well as consultants, try to identify ways in which firms can make profitable use of applications such as Wikipedia, YouTube, Facebook, Second Life, and Twitter.

Mobile Money and Financial Inclusion in Sub-Saharan Africa: the Moderating Role of Social Networks

ABSTRACT

The purpose of this article is to test the moderating effect of social networks in the relationship between mobile money usage and financial inclusion in rural Uganda. The results revealed that there is a significant and positive moderating effect of social networks in the relationship between mobile money usage and financial inclusion in rural Uganda. Besides, mobile money usage and social networks have direct and significant effects on financial inclusion in rural Uganda. Thus, the findings suggest that existence of social networks of strong and weak ties among mobile money users promote financial inclusion in rural Uganda. Previous studies have concentrated only on investigating the impact of mobile money in promoting financial inclusion in developing economies, especially in Sub-Saharan Africa. However, this particular study introduces the moderating effect of social networks in the relationship between mobile money usage and financial inclusion in rural Uganda, which seems to be sparse and lacking in literature.
