Rethinking social policy from a capability perspective

In this chapter, we discuss the key challenges and issues related to interpreting basic concepts of the capability approach (CA) in a social policy context. We start by briefly introducing the CA, tracing the idea of capabilities back to the writings of Aristotle and interpreting them in the context of Sen's capability approach. We then discuss the theoretical and empirical debates surrounding the CA as it was further developed by Nussbaum and later interpreted by other scholars such as Robeyns. The focus here is on the main conceptual and empirical debates in relation to social policy research and practice, centred on the key concepts in Sen's approach to capabilities: means, capabilities, functionings, conversion factors, and agency. Multiple interpretations of these concepts create difficulties in applying the CA to social policy research. This chapter offers a way forward in addressing these issues as they apply specifically to social policy research and practice.
