The role of blended value accounting in the evaluation of socio-economic impact of social enterprises

Social enterprise has become a key phenomenon in providing public services in many developed countries. The debate on the evaluation of the socio-economic impact generated by this kind of organization has gone hand in hand with the growth of social entrepreneurship. This study provides an exploratory analysis of the emerging practice of measuring the socio-economic impact of social enterprises using the theoretical construct called "Blended Value Accounting" (BVA). Among the models and tools proposed by BVA, we examine in particular the Social Return on Investment (SROI) - an instrument of causal contribution analysis – conducting a literature review on its application to the evaluation of socio-economic impact of social enterprises and on its implications for BVA. Finally, we reach a conclusion as to the role that these tools of mixed accounting and assessment might play - particularly the one examined – with respect to the positivist, critical and interpretative theories of accounting, thus identifying areas for further research.
