Yes, inflation is understated
Argument4 of 4

Inflation indices do not reflect reality

Much of the inflation basket is theoretical and not based on increases in price.

The argument

Since 1983, the government has measured the price of homes not by looking at house prices but by computing what it calls Owner's Equivalent Rent (OER); the rental value of a house. It accounts for nearly a quarter of the entire Consumer Price Index. When the change was made, the inflation rate diverged sharply from changes in house prices. The OER was fairly subdued while house prices surged before the housing bust, and afterwards the reverse happened. If the Federal Reserve had focused on house prices, it would have tightened monetary policy to deal with house price inflation. Instead it relied on OER, which understated inflation. The mechanisms the government uses to estimate inflation are not reflective of the reality of prices.

Premises

[P1]Since 1983 the government has measured housing not by house prices but by Owner's Equivalent Rent, which makes up nearly a quarter of the CPI. [P2] OER diverged sharply from actual house prices, staying subdued while prices surged before the housing bust. [P3] Relying on OER rather than house prices led the Fed to understate inflation and avoid tightening policy. [C] Therefore, because inflation indices do not reflect the reality of prices, inflation is understated.

Counter-arguments

Critics argue that using Owners' Equivalent Rent is a defensible choice, not a distortion. A consumer price index is meant to measure the cost of consuming shelter services, and a house price mixes that consumption with an investment asset — buying a home is partly buying an appreciating asset, not just paying for a place to live. Pricing shelter by rents deliberately strips out the asset-bubble component, so OER staying subdued while house prices surged is arguably the index working as intended rather than failing. They add that the argument rests on a single component and a single episode. Pointing to the pre-2008 divergence in one large category does not show the overall index systematically understates inflation, since other components can offset it and the rival 'inflation is overstated' position marshals the opposite case (quality adjustments, substitution). On this view OER is a methodological judgement economists debate, and one contested episode does not establish that inflation is understated overall.

Rejecting the premises

[Rejecting P1] Critics argue OER is a deliberate, defensible method: a cost-of-living index should measure shelter as consumption, and house prices conflate that with investment value, so pricing by rents is not a failure to reflect reality. [Rejecting P3] The pre-2008 divergence is one component in one period; it does not show the whole index systematically understates inflation, especially as others argue CPI overstates it, so the conclusion overreaches from a single case.
