"Consider the case of Ireland, which has been a good soldier in this crisis, imposing ever-harsher austerity in an attempt to win back the favor of the bond markets. According to the prevailing orthodoxy, this should work. In fact, the will to believe is so strong that members of Europe’s policy elite keep proclaiming that Irish austerity has indeed worked, that the Irish economy has begun to recover.
But it hasn’t. And although you’d never know it from much of the press coverage, Irish borrowing costs remain much higher than those of Spain or Italy, let alone Germany. So what are the alternatives?
One answer — an answer that makes more sense than almost anyone in Europe is willing to admit — would be to break up the euro, Europe’s common currency. Europe wouldn’t be in this fix if Greece still had its drachma, Spain its peseta, Ireland its punt, and so on, because Greece and Spain would have what they now lack: a quick way to restore cost-competitiveness and boost exports, namely devaluation."
