The euro area crisis demonstrated how weak economic policy coordination and loose fiscal oversight could destabilize a monetary union. To prevent the recurrence of such crises the EU and its member states determined to build ‘a deep and genuine economic and monetary union’ with reinforced governance structures. This multinational, 4-year project analyzes a rather neglected aspect of EMU, namely the politics of economic and fiscal integration. To fill the gap, the preferences of member states towards different models of fiscal union, and mechanisms of political consensus-building among member-states are studied in details through mixed methods. The consortium conducting this research is coordinated by the Salzburg Centre of European Union Studies (SCEUS), and covers all regions of the EU and consists of eight distinguished political scientists and one legal scholar.
