Housing equity withdrawal drove the bubble, not so much the building

Tim Duy also points to Bill McBride and Josh Lerner adding to the discussion of the narrative of housing in our economy and how that should affect policy.  I would add of course the variety of responses by the mortgage industries (see Naked Capitalism) since that started in earnest round 1998 (MERS).  I think this idea can be further refined and tied to other aspects of our troubles globally.

What Are We Expecting From Housing?, by Tim Duy: Josh Lehner and Bill McBride note that the manufacturing slowdown does not necessarily indicate recession, something I noted as well. Another version of that story is seen by comparing the ISM headline number with the new orders data:
 …During the 2002-2005 period, arguably the height of the housing bubble, residential construction contributed an average of 0.4 percentage points to GDP growth each quarter. In the first quarter of this year, the contribution was 0.42 percentage points. So, barring the occasional pop in the data, housing is already contributing to GDP growth about what we would expect.
 …Certainly we can envision accelerated home building triggering an increase in both manufacturing (capital equipment) and consumer (job/income growth) activity as well; these tend to be interconnected activities. So maybe the overall impact is a bit higher.

So here is the question: What was more important in holding the economy close to potential output, residential construction itself, or the housing price bubble? I tend to believe the price-driven balance sheet effects were driving dynamics over this past business cycle. Absent a healing of household balance sheets (or, relatedly, monetary policy that supported such healing via somewhat higher inflation expectations to reduce debt in real terms), I would expect overall growth to remain subdued, despite a rebound in residential construction. The latter is helpful and important, but not by itself a magic bullet.
