Paul Krugman attempts to whitewash his record on the failed stimulus program:
Those of us who say that the stimulus was too small are often accused of after-the-fact rationalization: you said this would work, but now that it hasn’t, you’re just saying it wasn’t big enough. The quick answer to that accusation is that people like me said that the stimulus was too small in advance. But the longer answer is that it’s all in the math: Keynesian analysis provides numbers as well as qualitative predictions, and given reasonable projections of the economy’s path in January 2009, the proposed stimulus just wasn’t big enough. Let’s go back to the tape, January 9, 2009:
Even the C.B.O. says, however, that “economic output over the next two years will average 6.8 percent below its potential.” This translates into $2.1 trillion of lost production. “Our economy could fall $1 trillion short of its full capacity,” declared Mr. Obama on Thursday. Well, he was actually understating things. To close a gap of more than $2 trillion — possibly a lot more, if the budget office projections turn out to be too optimistic — Mr. Obama offers a $775 billion plan. And that’s not enough.
Brilliant stuff! How does he do it? And now let’s go back to the tape only two months before, to November 8, 2008:
I wrote this morning’s column partly because I had a hunch that the Obama people might be thinking too small on stimulus. Now I have more than a hunch – I’ve heard an unreliable rumor! So let’s talk about stimulus math, as I see it….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.
Now, I may not be a Nobel Prize winner or a professional economist, but even lacking such credentials, I think I can successfully work out that $600 billion is SMALLER than $775 billion. Put not your trust in Keynesians.
