Paul Krugman is getting worried about Europe again:
The crisis takes a much longer time coming than you think, and then it happens much faster than you would have thought.
And so it is with the latest euro crisis. Not that long ago the austerians who had dictated macro policy in the euro area were strutting around, proclaiming victory on the basis of a modest uptick in growth. Then inflation plunged and the eurozone economy began to sputter — and perhaps more important, everyone looked at the fundamentals again and realized that the situation remains extremely dire.
Now, things looked very dire in the summer of 2012, too, and Mario Draghi pulled Europe back from the brink. And maybe, just maybe, he can do it again. But the task looks much harder. ...
Europe has surprised many people, myself included, with its resilience. And I do think the Draghi-era ECB has become a major source of strength. But I (and others I talk to) are having an ever harder time seeing how this ends — or rather, how it ends non-catastrophically. You may find a story in which Marine Le Pen takes France out of both the euro and the EU implausible; but what’s your scenario?
