EU Rules Beyond its Borders: The Policy-specific Effects of Transgovernmental Networks and EU Agencies in the European Neighbourhood

The European Union (EU) is increasingly involved in its rule advancement outside its borders through a dense net of transgovernmental networks. However, we know little about the effects of these networks. This article assesses the impact of transgovernmental networks across various policy domains in the European Neighbourhood Policy (ENP) region. Building on a novel longitudinal dataset, we demonstrate that the effects of transgovernmental networks vary across policy sectors. Policies marked by a higher degree of mutual interdependence exhibit greater positive change as a result of denser networks. Meanwhile, the involvement of EU agencies stimulates more intense technical co-operation and broadens the range of policy areas covered. In doing so, EU agencies serve as bridges for the establishment of strong links between the EU and its neighbours.
