It's not frequency but % of needs purchased. If you bought 100% of your housing (or food) needs 10 years ago, increased prices in the last 10 years won't impact you. Are you saying you buy groceries at the same frequency as you buy houses?
Everyone within a market, active, or inactive, is conscious of price pressures.
Please explain how this impacts CPI. Less than 3000 words if you can. Thanks.
Numerous ways it affects inflation (which is no longer measured by the CPI anyways) and is manifested. From hoarding "investing" to "bubble" psychology.
Any rate, getting back to your argument on frequency or as you try to frame it, %, you make a hypothetical claim of what, 1% transition among "first time" home buyers...as if they are the only ones? You have to square your number then with even the lame CPI assumption which does seem to weight the housing sector vastly higher as a component of the cost of living.
