Why would a dictionary tell me what you think NBER has to with hedonics?Feel free to look it up online or in the dictionary.NBER definition
Hedonics are purported quality improvements in products that reduce the real price of the good or service. The metrics for determining quality improvement would have made the Edsel the cheapest car of all time since it was chock full of cutting edge technologies that customers neither needed nor wanted. That is the classic rebuttal of hedonics with fees galore free checking also being a top 10 pick of those who find hedonics dubious.
Consequences of hedonics.
Inflation is understated and therefore real economic growth is overstated two ways directly which may be marginal and indirectly by overstating investment. Hedonics overstates real investment not so much when quality improvements are attributed to new capital equipment but when physical depreciation to existing capital equipment is understated in terms of replacement costs. The GNP and later GDP have overstated Net National Investment for the past half century which also coincided with the hollowing out of the US manufacturing base and massive real estate leverage (housing is considered capital investment). Prior to hedonics the quarter Trillion dollar S&L disaster was one such consequence of overstatement. Although it is not currently known how large the current bill will end up being the most conservatively run major bank, Morgan Chase, has just under $2 T mortgage exposure as owner or agent. That is one of the reasons JPM is so admired it mostly stayed out of the real estate bubble and was given WAMU and Bear Sterns along with being offered Morgan Stanley for free but that deal was refused. (Treasury Secretary Paulson made that offer during the WAMU takeover.) So how badly has hedonics overstated investment? I would recommend contacting Morgan Stanley, which is still in existence because nobody who was in good enough to take it over wanted it.
I have no idea of which are your words and which are supposed to be NBER's definition. You forgot to include a link. In any case I'm very familiar with hedonics, though the math gives me headaches. I wasn't asking what they are or why you think they're wrong, but rather what you think NBER has to do with it. Again..I'm not familiar with NBER putting out anything where they would use hedonics in their calculations..t.hat's usually done by statistical agencies, which NBER is not.
I already said it, I'll go with bold this time "In any case I'm very familiar with hedonics, though the math gives me headaches. I wasn't asking what they are or why you think they're wrong, but rather what you think NBER has to do with it."
No, they don't. And when were they ever involved in any official statistics? They're not a statistical agency, and never have been. They're not a government agency, and while they certainly do research and suggestions, they have NO official input into any government definitions or methodology. Where do you get these ideas?While the NBER may no longer be the chef in charge of this variety of book cooking just as they also backed out UE computation decades ago they are still the brain trust for coming up with new indices and ways of tweaking them.
