Over the last few decades, a consensus has emerged in international microfinance on the execution of microfinance impact assessments (MIAs). MIAs should be large-scale and longitudinal, tracking changes among clients over time, and making use of an appropriate control group (usually non-clients or pipeline clients) and/or location, isolating the impact of microcredits from other possible influences. On the back of a recent MIA conducted in the UK, this paper reflects on and discusses the feasibility and appropriateness of applying such a methodology in EU-15.
