Expert network interaction in the European Medicines Agency

The need for supranational regulatory capacity and the drive for governmental control are two colliding forces in international governance. As a solution to this governance dilemma, European administrative networks need to simultaneously fulfill the demand for supranational institutions and maintain governmental control. The assessment of risks associated with medicines authorized on the European market is carried out by such a network of national regulators as part of the European Medicines Agency. To uncover how these double‐hatted experts navigate the opportunity structures created by supranational and intergovernmental forces, this study employs social network analysis. Developing exponential random graph models, this study tests to what extent members can act as professional experts in service of the supranational administration and to what extent national features shape interaction. The results indicate that while PRAC members are socialized as professionals in service of supranational deliberation on pharmacovigilance, intergovernmental forces do structure their interactions.
