Scots, What the Heck?




Does Canada pay any price for independence? Probably. Labor productivity is only about three-quarters as high as it is in the United States, and some of the gap may reflect the small size of the Canadian market (yes, we have a free-trade agreement, but a lot of evidence shows that borders discourage trade all the same). Still, you can argue that Canada is doing O.K.


Could Scotland have its own currency? Maybe, although Scotland’s economy is even more tightly integrated with that of the rest of Britain than Canada’s is with the United States, so that trying to maintain a separate currency would be hard. It’s a moot point, however: The Scottish independence movement has been very clear that it intends to keep the pound as the national currency. And the combination of political independence with a shared currency is a recipe for disaster. Which is where the cautionary tale of Spain comes in.

If Spain and the other countries that gave up their own currencies to adopt the euro were part of a true federal system, with shared institutions of government, the recent economic history of Spain would have looked a lot like that of Florida. Both economies experienced a huge housing boom between 2000 and 2007. Both saw that boom turn into a spectacular bust. Both suffered a sharp downturn as a result of that bust. In both places the slump meant a plunge in tax receipts and a surge in spending on unemployment benefits and other forms of aid.

Then, however, the paths diverged. In Florida’s case, most of the fiscal burden of the slump fell not on the local government but on Washington, which continued to pay for the state’s Social Security and Medicare benefits, as well as for much of the increased aid to the unemployed. There were large losses on housing loans, and many Florida banks failed, but many of the losses fell on federal lending agencies, while bank depositors were protected by federal insurance. You get the picture. In effect, Florida received large-scale aid in its time of distress.

Spain, by contrast, bore all the costs of the housing bust on its own. The result was a fiscal crisis, made much worse by fears of a banking crisis that the Spanish government would be unable to manage, because it might literally run out of cash. Spanish borrowing costs soared, and the government was forced into brutal austerity measures. The result was a horrific depression — including youth unemployment above 50 percent — from which Spain has barely begun to recover.

And it wasn’t just Spain, it was all of southern Europe and more. Even euro-area countries with sound finances, like Finland and the Netherlands, have suffered deep and prolonged slumps.
