<re: core rate of PPI and CPI: with all due respect, these data look biased to me. as has been discussed on this thread previously, the
methods the DoL employs to arrive at these data are questionable. hard-to-measure "quality improvements" have entered into the
calculation as well as the substitution argument. seriously, what are you going to substitute gasoline with when it goes up in price?>

heinz, I agree that not including gasoline or housing in these stats makes no sense. But that is an entirely different issue from whether incorporating 'quality improvements' in these numbers increases or decreases their bias. I would suggest the latter, because let's face it, the economy is changing, so our methods of measuring it must reflect that fact....
