How Co-Production Regulates [PDF]

Social & Legal Studies, 2018
This article examines how and why regulatory influences tend to embed within the practices of co-production. Informed by empirical data derived from semi-structured interviews conducted with a sample of experts in co-production, the analysis seeks to illuminate some of the ‘soft’ and ‘interactive’ forms of regulatory work that are performed.
