AirBnB has, at best, a $56 million impact on the SF economy. Ben Bernanke is printing $85 billion per month to buy mortgage backed securities via QE3/4: http://www.forbes.com/sites/afontevecchia/2012/12/12/qe4-is-here-bernanke-delivers-85b-a-month-until-unemployment-falls-below-6-5/ http://www.forbes.com/sites/afontevecchia/2012/12/12/qe4-is-... QE4 is here. Only a few months after announcing what had been dubbed QE3, an open-ended $40 billion a month program to buy up mortgage backed securities (MBS), the FOMC decided to extend its asset purchases in 2013 as Operation Twist expires. Combined with QE3, the Fed will be taking $85 billion in bonds, both Treasuries and MBS It is likely that Bernanke's $85B/month has a far bigger impact on housing price inflation, and hence rent.
