In the Norwegian welfare state, family caregivers are increasingly regarded as a vital resource, as the number of people requiring health and care services continues to grow while the working-age population remains stable. In this context, the concept of co-creation has become more prominent in policy, research, and practice. Within the framework of “public service logic” (PSL), co-creation entails that service recipients and providers integrate their resources, such as knowledge and skill, to generate value. Scholars working in the PSL framework seem to assume that co-creation is inherently democratic and fosters social justice, yet they lack a clear framework for how justice is achieved or what kind of public value co-creation requires. In this chapter, we investigate the understanding of value co-creation inherent in the PSL framework and highlight forms of injustice in the opportunity for equal co-creation relationships between family caregivers and service providers, addressing a missing normative dimension in PSL. We explore: 1) what normative considerations are essential for fair co-creation conditions between relatives and service providers; and 2) how this reflection can deepen the understanding of the relationship between public and private value creation. By means of Nancy Fraser’s theory of recognition and empirical examples from research on family caregivers of children with disabilities, we illustrate how various dimensions of structural injustice manifest in co-creation contexts. We argue that Fraser’s principles of redistribution, recognition, and representation should be central to value co-creation practice and theory, proposing justice as a guiding normative concern in the development of PSL.
