+  abstract = {Over the last 35 years, microfinance has been generally regarded as an effective policy  tool in the fight against poverty. Yet, the question of whether access to credit leads to poverty  reduction and improved wellbeing remains open. To address this question, we conduct a  systematic review of the quantitative literature of microfinance's impacts in the developing world,  covering 54 studies out of 5311 identified studies. The analysis relies on a theory of change  framework that links the complex interactions and channels that exist between microfinance  activities, outputs, outcomes and impacts. Overall, we find that the limited comparability of  outcomes measured in the selected studies and the heterogeneity of microfinance-lending  technologies, together with a considerable variation in socio-economic conditions and contexts in  which impact studies have been conducted, render the interpretation and generalization of findings  intricate. This is coupled with a degree of uncertainty about the internal and external validity of a  considerable number of studies. Taking into consideration the limitations of the existing  empirical evidence, and cognisant of the absence of clear evidence, we conclude that microfinance  is likely to induce short-term dynamism in the financial life of the poor and vulnerable non-poor,  although this dynamism seems to fall short of achieving sizable impacts on consumption  expenditures, human capital and assets, and, ultimately, poverty reduction.},
