This volume offers a substantial contribution to the collaborative modes of the Nordic welfare states. We provide critical perspectives on the collaborative turn in the Nordics and elaborate on how co-production is implemented in policies, civil society, and institutional changes. Co-production through partnerships and collaboration with citizens, the public sector, and civil society is on the political and administrative agenda of Sweden, Norway, Finland, and Denmark. However, the degree and shape of co-production differ among the four countries. These differences as well as similarities are examined in the fifteen chapters of this edited book.
