The role of national culture in the relationship between microfinance outreach and sustainability: a correlated random effects approach

Abstract

PurposeThis study investigates the role of national culture between outreach and sustainability of microfinance institutions (MFIs). Despite microfinance's deep embeddedness in cultural contexts, research on the influence of national culture on MFI performance is rather sparse. This paper seeks to fill this gap and, based on cross-country microfinance data, attempts to explain the outreach-sustainability relationship in reference to cultural factors.Design/methodology/approachAn unbalanced panel, consisting of 5,741 MFI-year observations of 1,232 MFIs from 43 countries in six regions, is drawn from the Microfinance Information Exchange (MIX) Market database. Two different econometric models are tested. Model 1 estimates the direct effect of outreach on sustainability, using a fixed-effects estimator. Model 2 examines the moderation effect of national culture on outreach-sustainability relationship, employing correlated random effects approach.FindingsThe results show that depth of outreach and financial sustainability of MFIs are negatively related, and the relationship is moderated by national culture. Power distance and uncertainty avoidance positively moderate the outreach-sustainability relationship, whereas individualism and masculinity negatively moderate the relationship.Originality/valueThe findings suggest that the national culture where MFIs are located plays an important contingent role in their performance and that the magnitude of the trade-off effect varies from culture to culture. The research thus provides further insight in the trade-off debate and contributes to literatures of both microfinance and cross-cultural management.
