Collaborating in future states—Contextual instability, paradigmatic remaking, and public policy
Australian Journal of Public Administration, EarlyView.Abstract Collaboration is ubiquitous in public policy life, with its presence and profile determined by prevailing governance conditions. Commitments to globalisation and marketisation in the latter part of the 20th century marked the onset of an era defined by collaboration, between and across tiers and spheres of government, with non‐state actors ...
