The Research Working Group of the EMN created the Electronic Research Bulletin (eRB) in recognition of the need for a benchmark publication on microfinance related research at the European level. This issue investigates the hot topic of social performance (SP). Recent microfinance news regarding over-indebtedness and impact evaluation has led the sector to re-evaluate its methods and re-examine social performance. This edition of the eRB gives a theoretical and practical background on the current status of social performance in Europe.
