title: Using cost-benefit analysis and social return on investment to evaluate the impact of social enterprise: Promises, implementation, and limitations.
abstract: Since the early 2000's there has been growing interest in using the Social Return on Investment (SROI) as a measure for assessing the performance of social enterprises. By analogy with its business counterpart, the Return on Investment (ROI), the SROI is a metric that compares the monetized social costs of a program with the monetized social benefits of achieving an outcome (or set of outcomes). For example, calculating the SROI of a nonprofit half-way house for drug addicts might involve estimating the reduced social costs attributable to successful rehabilitation of addicts, and comparing this to the social costs of operating the half-way house. Alternatively, the total return of a for-profit social enterprise providing affordable housing might consist both of the traditional private return on investment along with the economic value of meeting the housing needs of lower income households. Early descriptions of the methodology for calculating the SROI suggest that the approach initially evolved from standard methodologies found in the business finance literature for evaluating investments, with the important twist that nonprofit sector returns/payoffs are defined in broader social terms (Thornley, Anderson, & Dixon, 2016). Yet, someone who is familiar with the economic literature on cost benefit analysis (CBA) as it is applied to the evaluation of public programs cannot help but be struck by the similarity between the outcomes that CBA is intended to measure, and those that are the object of efforts to calculate the SROI. One implication is that the literature on the theory and practice of cost benefit analysis offers useful lessons about how to measure the social return on investment, as well as about potential caveats and limitations that need to be confronted when attempting to undertake an analysis of the SROI. The paper discusses the potential uses and limitations of CBA and SROI as tools that governments, private donor/investors, and foundations can use to help set funding priorities, and evaluate performance. It summarizes: (1) the conceptual foundations of CBA and its application to SROI analysis, (2) issues raised in the implementation of CBA and SROI in practice, and (3) discusses when CBA and/or SROI approaches are a useful lens for setting priorities and/or evaluating performance, as well as important limitations of such methods.
