"The Substitution Effect
Substitution also plays a role in reducing the CPI. From 2001-2003 the CPI index fell by 1.6% reaching a low of 1.1%. Wall Street and the Fed were talking about the risk of deflation. Deflation was predicted everywhere in the press. The financial world became fixated over the risk of deflation even though the monetary presses were working overtime, credit was mushrooming, and asset bubbles were inflating in the mortgage, bond, and real estate markets. The reason for the decline was the substitution effect. Instead of using new car prices, which were going up each year, the BLS substituted used car prices, which were falling. In place of exploding real estate prices, the Bureau gave more weight to the price of rents, which were falling as more households bought homes. Rents were given more weight even though 69% of households own a home versus the 31% that rent."..............
"Many homeowners may not be aware that as a homeowner they receive a fictional income referred to as Ownerâs Equivalent Rent (OER). Essentially the BLS samples the price of rents in residential housing to come up with what a homeowner would receive hypothetically if they were to rent their own home. That sounds idiotic to me, since most homeowners would agree the family castle is in many cases a money pit and not a source of income. Unless the home is owned free and clear, most homeowners have cash outgo each month due to mortgage payments, property taxes, utilities, and repairs. As absurd as this concept appears, OER gets the largest weighting in the CPI index of 23% versus actual rent, which gets only a 6% weighting. OER is purely fictional, yet it carries the greatest weight within the CPI index.
Hedonics helps the BLS keep rising prices for goods in the CPI from ever showing up as rising prices. Even though the cost of housing, energy, food, medical bills, prescription drugs, tuition, and entertainment have soared, the government keeps reporting moderate inflation. Hedonics is partially responsible. It has become a convenient and subjective way of removing prices increases from the CPI. The combination of substitution, changing the weight of goods rising in price, hedonics and seasonal adjustments is one reason why the CPI and reported inflation has remained as subdued as it is reported each month. The problem is that these numbers are all fictional and bare no resemblance to what households face each month with their actual budgets."
