2. In 2012, there were many Euro and EU doom-mongers. Many were the world's leading economists and investors (Paul Krugman - NY Times Nobel winning Economist, billionaire George Soros, Willem Buiter, chief economist at Citigroup).
Nouriel Roubini, the New York University economist whose bearish forecasts earned him the nickname "Dr. Doom", has been in the gloom camp from the beginning, predicting as far back as 2010 that countries would be forced to abandon the single currency.
Now he says the risks of a near-term catastrophe have been reduced. Reflecting the more cautious view of many of his colleagues, Roubini believes 2013 will be another year in which European politicians "muddle through", avoiding catastrophe.
Economists like Eichengreen are reluctant to declare the worst of the crisis over, pointing to deep recessions on Europe's periphery and the risk of political complacency.
At a December summit in Brussels, European governments delayed serious discussion on closer fiscal integration until mid-2013 and made clear that creation of a "banking union" would stretch into 2014 and beyond.
