Much research on EU integration looks at the “core” EU countries, and analyses the speed and priorities for taking forward the European project. This conference recognizes that “one size does not fit all” within the EU context, and that prematurely fitting all member states with the same shoe may undermine the stability not only of that member state but also to EU as a whole. There are trade-offs for member states as to when and if to join the euro, and whilst they are outside the euro whether to join the banking union. The conference will examine these issues, as well as two other issues of importance to some of these countries: the future of the Vienna Initiative and the framework of macroprudential policies in the EU as it affects countries outside the core. This conference is open to the public.
