Quote from xenix:
The point is that spending is not as elastic as one might think. I'm not saying that deleveraging will have NO effect. I'm saying that quantitatively, the magnitude of the effect is subject to debate.
Also, let's not forget that investment is between 15 and 20% of GDP. So when the savings rate goes up, it's not as if that money is being picked out of the economy's pocket.
Of course the response to that is that it's not savings or investment if you're paying down debt. But again, that money isn't just disappearing. It's going into the pockets of the people who made all that leverage possible, and they're going to take that money and do what with it? Toss it on the barbie? Uhhh, I don't think so. It will go back into the economy as investment and hence will contribute to GDP.
