See Euro Future

Here’s Charlie Calomiris from back in 1999, predicting a bad end to the Euro.

I predict that the euro will be a weak currency (one that will not retain its value against the dollar), and that it will not be a permanent currency. Ultimately, the euro will most likely be remembered neither as a textbook example of the social gains of properly defining the optimal currency area nor as the harbinger of global exchange rate stability, but rather as an illustration of the importance of fiscal discipline for monetary credibility, and as a monetary example of the tragedy of the commons.

European union will likely strengthen the attraction of the dollar as a numeraire and a store of value. Countries outside of Europe will continue to peg their exchange rates to the dollar. And when the European Monetary Union ultimately collapses, it will itself provide a positive shock to the real dollar exchange rate that will hurt countries that have pegged to the dollar. All of this is unfortunate from the standpoint of global macroeconomic stability—an example of how political constraints that limit rational policy and encourage public profligacy make the global economy less stable than it otherwise would be.

I picked that up from Marginal Revolution, where Tyler Cowen points out that economists from Paul Krugman to Milton Friedman were pessimistic on the long-term prospects.

Here’s Freidman:

I think the euro is in its honeymoon phase. I hope it succeeds, but I have very low expectations for it. I think that differences are going to accumulate among the various countries and that non-synchronous shocks are going to affect them. Right now, Ireland is a very different state; it needs a very different monetary policy from that of Spain or Italy. On purely theoretical grounds, it’s hard to believe that it’s going to be a stable system for a long time.

If we look back at recent history, they’ve tried in the past to have rigid exchange rates, and each time it has broken down. 1992, 1993, you had the crises. Before that, Europe had the snake, and then it broke down into something else. So the verdict isn’t in on the euro. It’s only a year old. Give
it time to develop its troubles.

The snake?

At any rate, Cowen’s point is that economists may have whiffed the financial collapse, but they seemed to hit the ball on the Euro.
