The future of the European Union: Towards a functional federalism

The series of adverse shocks of both economic and political character that Europe has suffered since 2008, the last of them coming from the Brexit referendum, revealed numerous institutional gaps and asymmetries in the EU integration architecture. They originate from the voluntary nature of the EU project and the necessity to obtain unanimous approval of all member states to take new integration steps. To increase the resilience of the EU project against current and future shocks, its major institutional gaps and asymmetries should be addressed as quickly as possible. In this paper, we use the theory of fiscal federalism and subsidiarity principle to set the agenda of the EU reform. This includes the identification of areas such as completing the EMU and Schengen projects, foreign, security, and defence policies, environmental and climate change policies where further integration can offer substantial returns to scale and better provisions of global and pan-European public goods. On the other hand, there are also areas such as agriculture policy, products, services and labour standards, and fiscal surveillance rules, where deregulation in favour of market forces could ease business environment and make EU regulations less bureaucratic. Developing integration beyond the traditional economic sphere will also have an impact on the size of the EU budget, balance of power between the EU governing bodies (a bigger role of the European Parliament) and the democratic legitimacy of the EU project.
