$this->bbcode_second_pass_quote('Denny', 'I') place no credibility in the official CPI anymore. Let's look at today's news item, I see this today on
CNN Money: "Consumer prices edge higher":
"
The Consumer Price Index, the government's key inflation measure, rose 0.3%, compared to February, when prices were unchanged. The gain matched the forecasts of economists surveyed by Briefing.com." - Just up 0.3% in a month, overall? Thus, it cost you just $100.30 for what cost you $100 in February. Does this match anybody's perceptions?
"
The price of energy jumped 1.9% percent in the month." So, in other words, if a typical consumer paid $3.20 for a gallon gas in February, that same gallon would have cost about $3.26 in March, Up about 6 cents. Does this match anybody's exprience? I saw gasoline rise 6 cents a gallon in just one week in Florida in March.
I've been really fascinated with economics as of late, and the more I read about the subject the more I realize that its too complex to try and write out one equation to define an economic term like CPI.
What many economists seem to want to try and do is model thing just like they do in physics with fundamental laws. For example
F=ma
or
E=mc^2
interactions between people are not so simple things, and often depend upon a series of cascading conditions. So if I was going to try and make an accurate math model of human interaction (which is way beyond my own math skills), I'd take idea from quantum mechanics, which basically is just calculating the probability or a less fancy terms would be "odds"
people don't seem to understand, that a something like the CPI is basically just an educated guess, with lots of error, because its impossible to have a CPI calculation that accounts for all variables.
No if you're asking could the CPI be better calculated with more accuracy, the answer is "yes" but the problem is if ya change the CPI equation too much, then I see a problem of trying to compare a 2008 CPI based on a basket of goods (which might have items we take for granted like computers and cell phones), with a 1945 CPI (which did not have items like a computer). Think about the fact that in 1945, some leading minds said all the world needed was 5 computers, back then the "bomb" which was used to crack the enigma codes was one such computer, that cost in todays dollars hundreds of millions. But now an iPod touch has hundred of times the computing power of WWII computers, yet costs one one millionth the price.
