社会资本
Social capital has been associated with the reduction in access to informal credit in informal economies (especially in developing countries). Mwangi and Ouma (2012) ran a bivariate probit model on financial access national survey data to the impact of social capital on financial inclusion in Kenya. They determined that membership to groups increased one's probability of getting an informal loan by 1.45% and also the more group memberships one held, the more likely they were to access an informal loan.
