IMF's Blanchard: Global Economy Gripped By Meta-Uncertainty - WSJ.com - 0 views

In 2008-09, there was a collapse of global trade. We were all very surprised. Output was not doing well, but the collapse in global trade was enormous. We realized at the time that the elasticity of trade with respect to global output was not 1, as you might think, but more like 3 to 4. So this explained it. And then it recovered like crazy.

These countries have to do what they need to do. There’s no question there has to be fiscal consolidation. We can discuss the pace, but it has to happen. The other is competitiveness, which I see as much tougher of the two.
-
It has to be through a combination of structural reforms, hoping they will work, and nominal wage adjustments, although one cannot be incredibly optimistic about the scope there. We know that that’s going to take a while.

Take the big two, Italy and Spain. You can always dream of more, but I think they’re serious about doing it, both on the fiscal front and the structural-reforms front. I think it may well be that even if they do everything they can, and do it right, it’s still not enough. They have to have help — I would say when needed rather than if needed.

The banks have to be recapped, and they have to be recapped not using sovereign money. I think that is really very, very high on the agenda. I don’t think they can make it without help to the banks.
-
And the sovereigns have to be able to borrow at reasonable rates. As long as they behave and they do all the things they’re asked to do, they have to be able to borrow at lower rates than they currently do. Some way has to be found to do it.

It’s not that I don’t care about the way it’s done. But I care about the result. These countries, if they’re doing the right things, they have to be able to finance themselves.

Some people say a euro depreciation would help Europe a lot. I think there is an argument for it, even in a multilateral context. You have to depreciate vis-a-vis somebody, so somebody has to appreciate. My sense is we would like most of the depreciation to be vis-a-vis emerging-market countries. Even if there was a depreciation vis-a-vis the dollar, I still think it would be a good thing.

We’ve done simulations. Other people have done simulations as well. 10% real depreciation would lead to a 1.4% increase in growth for a year — which at this stage, given the numbers, would be nice. The footnote, and it’s a very big footnote, is that … how much you benefit depends on how big your exports are related to your GDP and where you export — whether you export in the euro zone or outside. Unfortunately the countries that benefit the most are the countries that really don’t need it — Germany, the Netherlands. The countries that benefit the least are Greece, Portugal, Italy, Spain

There’s no question, the periphery countries have to improve their competitiveness. That’s not something even monetary policy at the level of the euro or fiscal policy can do. This they have to do through productivity improvements or nominal wage adjustments.

At this stage I think there is a genuine commitment to thinking about the whole beast. That’s why these words — fiscal union, banking union — have come in.

Where I think there is still a problem is that all these things will take a lot of time. And some of these things may not happen because they’re unpopular. And meanwhile, there is a fire in the house. So they have to be willing to do more in the short term.
