As the state has become more susceptible to global pathologies, public policy scholars have found increasingly common ground with their IPE cousins. The development of these relatively young fields of study -increasingly they are sub-disciplines -has been commensurate but rarely intersecting. Yet contemporary maelstroms of global politics, economics, health, and security, span borders with ease, and increasingly force us to recognise, reconsider, and reconceptualise the overlapping realms of

... national and international. In so doing, we must overcome the disciplinary distinctions. In this article, we traverse the prominent in-built disciplinary imperatives and methodologies that have kept these two disciplines from concerted inter-operability or, at least, interchange of theories and concepts. To do so, we begin by presenting a brief overview of the conceptual pedigrees and trajectories of these disciplines, before drawing attention to the prominent prevailing overlaps, 'trespasses' and tensions as they specifically relate to policy convergence and diffusion, and policy transfer. We proceed to specify a reconciliation of these tensions through, in the third section, a brief study of the growth of global administrations, administrators, and administrative spaces. This, we contend, stands as a paradigm case of how reconciled IPE/public policy concepts can produce enhanced theoretical and substantive insights into the transnationalising political world.
