Abstract Lending groups (LGs) and social capital are two central elements to the many microfinance solutions operating around the world. However, LG effectiveness in reducing transaction costs and lending risks for microfinance institutions (MFIs) is mediated by institutional environments. Starting from this assumption, we discuss the existent interactions between the institutional environments of developed (Anglo-Saxon and communitarian) and developing countries with different stocks of social capital (individual, network and institutional) and the influences of this interaction on LG effectiveness. In order to do so, we applied the institutional perspective of O. Williamson to build a theoretical framework to examine the interaction of all these conditions, allowing for analysis of their main relations within the microfinance context. Based on this framework, we propose on the one hand that in developing and Anglo-Saxon developed nations, stocks of both individual and network social capital are the most important for an LG's effectiveness. However, in Anglo-Saxon countries, these two stocks of social capital are complemented by formal contracting devices. In communitarian developed countries, on the other hand, the stocks of institutional social capital have a stronger positive impact on LG dynamics.
