From Zero Hedge:

Now we hear from none other than Mark Zandi of Moody’s Economy that the government’s tacit encouragement for “homeowners” to not pay their mortgage dues is freeing up $8 billion each month that is artificially increasing consumer spending and iPad preorders. And with banks not marking anything to market, all these houses that generate no cash flow are still marked at 100 cents on the books.

And then more from the same article…

it amounts to nearly one percent of consumer spending. The saving rate is also much lower as a result. The impact on spending growth is less significant as that is a function of the change in the number of homeowners not making payments.

I’m not sure I would say this is juicing up spending, but resulting in more spending than would be the case otherwise.

Many of these stressed homeowners (due to unemployment) are reducing their spending, just not as much as they would have if they were still making their mortgage payment.
