Credit-worthiness prediction in microfinance using mobile data: A spationetwork approach

Abstract

Many communities in underdeveloped and developing economies of the world suffer from lack of access to personal credit via formal financial institutions, like banks. However, with the rapid increase in Internet and mobile phone penetration rates, firms are now trying to circumvent this problem using novel technology-enabled approaches. In this research, we leverage a real-world dataset obtained in collaboration with a microfinance firm to show that locational data from mobile phones, coupled with information about communication networks, can be effectively exploited to improve prediction of loan default rates. Specifically, we draw upon recent work in network cohesion based regression modeling to develop a model that uses locational predictors, but within a networked context. We contend that the results from our research can not only illuminate how locational data might be used in assessing creditworthiness, but also empower microfinance firms in resource-poor communities with novel methods for credit scoring.
