The history of European integration has been characterized by several ‘stops-and-goes’ with considerable support on political grounds. In this video, Corrado Macchiarelli (Brunel) discusses the role of European integration for the future of the EU-UK relations. Integration, consistent with the idea of ‘completing’ the European Monetary Union (hence, a ‘Genuine Economic and Monetary Union’- GEMU) would affect the UK as well, irrespective of whether it will withdraw from the EU. Costs and benefits of EU membership should hence take GEMU into account. This video was recorded in June 2016 during the “Economics of the UK-EU Relationship” workshop at Brunel University London.
