Un-solvable crises? Differential implementation and transboundary crisis management in the EU

Abstract

Abstract Much has been said about how crises in the EU create disintegration or differentiation pressures. Considerable attention has been paid to EU crisis governance mechanisms. Yet, less attention has been paid to the anticipation of effects of differentiated implementation on transboundary crisis management regimes. This article asks how differential policy integration accommodates the anticipation of differential implementation through institutional choices in transboundary crisis management regimes. Concerns about the consequences of national customisation influence the way in which transboundary crisis management regimes develop in terms of allocation of authority and constraints on member state discretion. The paper compares EU transboundary crisis regimes in four sectors: banking, electricity, youth unemployment, and invasive alien species. Concerns with ongoing differential implementation of transboundary crisis management generate further inevitable tensions in governance systems, leading to continued contestation over institutional arrangements.
