The Eurozone crisis which started in spring 2010 as a Greek budget crisis has alerted Europeans that the issue of defaulting sovereigns is not one reserved just for the poor and poorest countries on this globe. The crisis painfully amplified that developed countries, too, might be hit by this phenomenon. To be sure, this insight is far from novel - the history of defaulting states reaches back into history for at least two millennia. And yet, lawyers have surprisingly abstained more or less completely from discussing this subject and developing possible solutions. Beginning with the Argentina crisis in 2001, this neglect began to vanish to a certain degree and this movement got some momentum in 2010 by the Eurozone crisis. The present book collects contributions from authors most of whom have participated in a conference on this issue in January 2012 at the Humboldt-Universitat zu Berlin. The presentations, thus, provide a unique overview of the present discussion both from an economic and legal perspective.
