We talked about housing prices, and I recognize there are a bunch of different ways to include this in the CPI. One thing we could look at would be the disposable income of the household and how much is going to shelter, just in and of itself.
I'm curious as to whether you've done any studies. Can you point to any information on the health of discretionary spending in a household? Perhaps the government has asked you to look at this with respect to housing in particular and how much of disposable income is going to shelter.
