The papers and commentaries presented at the conference addressed many important issues related to the functioning of the euro area. Our hope is that these contributions will help improve understanding of the nature of Europe's monetary union, the underpinnings of its crisis, and the changes that are needed so that crises will be prevented in the future. The papers examined two main sets of issues. One group of papers, adopting a union-wide perspective, assessed the aspects of the euro area's institutional architecture that, with the benefit of hindsight, may have contributed to the crisis, and the policy responses to the crisis at the union level. A second group of papers focused on developments in three crisis countries-Greece, Ireland, and Portugal.
