Need help calculating portion of US productivity tied to house bubble

Hi Folks

I keep hearing about how technology is what is boosting US productivity numbers, but I am wondering if there isn't more going on.

Are rising US new house prices turning into "productivity gains"?

Think hard!

While determining GDP, GNP and inflation calculations is fairly straightforward, I have not yet been able to figure out what relative proportion residential fixed investment (which creates new homes)contributes to recent US productivity reports.

More specifically, I am looking to determine how the calculation of productivity relates to average new home price--residential investment--apparently absent a deflator like other GDP categories; it looks to me like they use owners equivalent rent like in the CPI!

Granted, if parts of homes are built in other countries and shipped over here, that would be a boost in itself.

Thus, it seems to me productivity figures in quarters where many new homes were built would be fully imaginary.

Someone help me out, or counter-argue as to how rising home prices are not otherwise reported as productivity gains, assuming fixed input quarter over quarter...
