摘要:Competition is often praised for enhancing efficiency in the process of resource-allocation. However, it could also put at risk the sustainability of firms operating within certain industries such as the financial sector. This could have further managerial implications when it comes to social enterprises such as microfinance institutions (MFIs). Using data from Superintendencia de Economía Popular y Solidaria over the period 2016-2019, this study aims at analyzing the aspects of competition on sustainability of Ecuadorian MFIs. More specifically, the research focuses on savings and credit cooperatives (SACCOs). Relying on both the structural and non-structural approach to measure competition at a firm level, findings are in line with an important portion of the microfinance literature claiming that competition is negatively associated with the main measures of financial sustainability and portfolio quality.
