Paul Krugman: Now and Later

Spend now, while the economy remains depressed; save later, once it has recovered. How hard is that to understand?

Very hard, if the current state of political debate is any indication. All around the world, politicians seem determined to do the reverse. They’re eager to shortchange the economy when it needs help, even as they balk at dealing with long-run budget problems.

But maybe a clear explanation of the issues can change some minds. So let’s talk about the long and the short of budget deficits. I’ll focus on the U.S. position, but a similar story can be told for other nations.

At the moment, as you may have noticed, the U.S. government is running a large budget deficit. Much of this deficit, however, is the result of the ongoing economic crisis, which has depressed revenues and required extraordinary expenditures to rescue the financial system. As the crisis abates, things will improve. The Congressional Budget Office, in its analysis of President Obama’s budget proposals, predicts that economic recovery will reduce the annual budget deficit from about 10 percent of G.D.P. this year to about 4 percent of G.D.P. in 2014.
