“…We fill this research gap and quantify microfinance by several generally accepted MFI performance indicators namely, number of clients served, percentage of female borrowers, average loan balance, portfolio at risk, return on assets, operational self-sufficiency, and operating expenses. Then, we improve current research that has measured economic development by GDP growth and GNI (e.g., Eigbiremolen & Anaduaka, 2014;Maksudova, 2010;Vanroose & D'Espallier, 2013) and expand our analysis to further economic development indicators that have been found to interrelate with microfinance (e.g., Morduch, 1999). Hence, we consider not only GDP growth and lagged GNI per capita but also indicators such as poverty headcount ratio, income inequality, capital formation, labor participation as well as literacy rate.…”
