The Looming Economic Scenarios

2

All told, I’m betting we’re looking at $1 trillion in stimulus in the next few years.

Steve Coll:

The economy is about $14 trillion in size, so that’s potentially more than a trillion dollars beyond what has already been expended on rescue measures. (Obama and the Democratic-led Congress are starting much smaller—about $60 billion in stimulus measures will be taken up in the lame-duck session, and then, after the Inaugural, most second-round proposals are in the range suggested by the Princeton economist Alan Blinder over the weekend; two per cent of G.D.P., or about $280 billion.) Even without a very large stimulus, Obama will likely be the first President to preside over a $1 trillion federal-budget deficit.

And then Krugman, via Drum…

So we need a fiscal stimulus big enough to close a 7% output gap. Remember, if the stimulus is too big, it does much less harm than if it’s too small. What’s the multiplier? Better, we hope, than on the early-2008 package. But you’d be hard pressed to argue for an overall multiplier as high as 2.

When I put all this together, I conclude that the stimulus package should be at least 4% of GDP, or $600 billion.

Yes, it’ll hurt, but not doing anything will hurt even more.
