In a recent report, Milunovich noted that the Bureau of Economic Analysis (BEA), whose job it is to compute the Gross Domestic Product each quarter, has "stopped reporting the real computer hardware shipment figure used to calculate real GDP growth, though it is still used in GDP calculations." The BEA, which is part of the Commerce Department, made this readjustment because it is "concerned the rapid price declines for computers made the figures misleading."
Let's stop and review the bidding for a second. Remember: GDP is the measure of goods and services produced in this country. The government decided that certain of its data series involved in calculating GDP were misleading. So, what did it do? Simply stop breaking them out. Makes sense to me; how about you?
This would be a humorous window into the lunacy of government calculations, were it not so important to many statistics. Regular readers of my daily column know that the magic of "hedonics" and all its attendant distortions is something that I have railed about for a long time.
Hedonics: 'miracle' tonic for an ailing economy
For those of you who don't know, hedonics is the way the government transforms price declines into quality improvements. To wit, you buy a PC with twice as much power, so the government concludes that you really paid only half as much money for it. Hedonics is also the government's way of taking quality improvements and converting them into price declines when calculating the CPI. Sure, that brand-new Chevy you just bought cost 40% more than it used to, but it's a 40%-better car for a variety of reasons. So, the government says, the price didn't really go up. (I have oversimplified these examples, but you get the point.)
