Paul Krugman: The Comeback Continent

Today I’d like to talk about a much-derided contender making a surprising comeback, a comeback that calls into question much of the conventional wisdom of American politics. No, I’m not talking about a politician. I’m talking about an economy — specifically, the European economy, which many Americans assume is tired and spent but has lately been showing surprising vitality.

Why should Americans care about Europe’s economy? Well, for one thing, it’s big. The G.D.P. of the European Union is roughly comparable to that of the United States; the euro is almost as important a global currency as the dollar; and the governance of the world financial system is, for practical purposes, equally shared by the European Central Bank and the Federal Reserve.
