Life Support

Paul Krugman fears that the US economy might be on life support for a long time: Life Without Bubbles.

Whatever the new administration does, we’re in for months, perhaps even a year, of economic hell. After that, things should get better, as President Obama’s stimulus plan — O.K., I’m told that the politically correct term is now “economic recovery plan” — begins to gain traction. Late next year the economy should begin to stabilize, and I’m fairly optimistic about 2010.

But what comes after that? Right now everyone is talking about, say, two years of economic stimulus — which makes sense as a planning horizon. Too much of the economic commentary I’ve been reading seems to assume, however, that that’s really all we’ll need — that once a burst of deficit spending turns the economy around we can quickly go back to business as usual.

In fact, however, things can’t just go back to the way they were before the current crisis. And I hope the Obama people understand that...

A more plausible route to sustained recovery would be a drastic reduction in the U.S. trade deficit, which soared at the same time the housing bubble was inflating. By selling more to other countries and spending more of our own income on U.S.-produced goods, we could get to full employment without a boom in either consumption or investment spending.

But it will probably be a long time before the trade deficit comes down enough to make up for the bursting of the housing bubble. For one thing, export growth, after several good years, has stalled, partly because nervous international investors, rushing into assets they still consider safe, have driven the dollar up against other currencies — making U.S. production much less cost-competitive.

Furthermore, even if the dollar falls again, where will the capacity for a surge in exports and import-competing production come from? Despite rising trade in services, most world trade is still in goods, especially manufactured goods — and the U.S. manufacturing sector, after years of neglect in favor of real estate and the financial industry, has a lot of catching up to do.

This could be a good time for the US to come up with something the rest of the world wants to buy. Exotic financial instruments might not be the way to go.
