Bill Gross (PIMCO) on the fishy US inflation calculations

Excerpt from PIMCO's June 2008 Investment Outlook:

. . . I’ll tell you another area where we’ve been foolin’ ourselves and that’s the belief that inflation is under control. I laid out the case three years ago in an Investment Outlook titled, “Haute Con Job.” I wasn’t an inflationary Paul Revere or anything, but I joined others in arguing that our CPI numbers were not reflecting reality at the checkout counter. In the ensuing four years, the debate has been joined by the press and astute authors such as Kevin Phillips whose recent Bad Money is as good a summer read detailing the state of the economy and how we got here as an “informed” American could make.

Let me reacquaint you with the debate about the authenticity of U.S. inflation calculations by presenting two ten-year graphs – one showing the ups and downs of year-over-year price changes for 24 representative foreign countries, and the other, the same time period for the U.S. An observer’s immediate take is that there are glaring differences, first in terms of trend and second in the actual mean or average of the 2 calculations. These representative countries, chosen and graphed by Ed Hyman and ISI, have averaged nearly 7% inflation for the past decade, while the U.S. has measured 2.6%. The most recent 12 months produces that same 7% number for the world but a closer 4% in the U.S.



This, dear reader, looks a mite suspicious. Sure, inflation was legitimately much higher in selected hot spots such as Brazil and Vietnam in the late 90s and the U.S. productivity “miracle” may have helped reduce ours a touch compared to some of the rest, but the U.S. dollar over the same period has declined by 30% against a currency basket of its major competitors which should have had an opposite effect, everything else being equal. I ask you: does it make sense that we have a 3% – 4% lower rate of inflation than the rest of the world? Can economists really explain this with their contorted Phillips curve, output gap, multifactor productivity theorizing in an increasingly globalized “one price fits all” commodity driven global economy? I suspect not. Somebody’s been foolin’, perhaps foolin’ themselves – I don’t know. This isn’t a conspiracy blog and there are too many statisticians and analysts at the Bureau of Labor Statistics (BLS) and Treasury with rapid turnover to even think of it. I’m just concerned that some of the people are being fooled all of the time and that as an investor, an accurate measure of inflation makes a huge difference.




The U.S. seems to differ from the rest of the world in how it computes its inflation rate in three primary ways: 1) hedonic quality adjustments, 2) calculations of housing costs via owners’ equivalent rent, and 3) geometric weighting/product substitution. The changes in all three areas have favored lower U.S. inflation and have taken place over the past 25 years, the first occurring in 1983 with the BLS decision to modify the cost of housing. It was claimed that a measure based on what an owner might get for renting his house would more accurately reflect the real world – a dubious assumption belied by the experience of the past 10 years during which the average cost of homes has appreciated at 3x the annual pace of the substituted owners’ equivalent rent (OER), and which would have raised the total CPI by approximately 1% annually if the switch had not been made.

In the 1990s the U.S. CPI was subjected to three additional changes that have not been adopted to the same degree (or at all) by other countries, each of which resulted in downward adjustments to our annual inflation rate. Product substitution and geometric weighting both presumed that more expensive goods and services would be used less and substituted with their less costly alternatives: more hamburger/less filet mignon when beef prices were rising, for example. In turn, hedonic quality adjustments accelerated in the late 1990s paving the way for huge price declines in the cost of computers and other durables. As your new model MAC or PC was going up in price by a hundred bucks or so, it was actually going down according to CPI calculations because it was twice as powerful. Hmmmmm? Bet your wallet didn’t really feel as good as the BLS did.

In 2004, I claimed that these revised methodologies were understating CPI by perhaps 1% annually and therefore overstating real GDP growth by close to the same amount. Others have actually tracked the CPI that “would have been” based on the good old fashioned way of calculation. The results are not pretty, but are undisclosed here because I cannot verify them. Still, the differences in my 10-year history of global CPI charts are startling, aren’t they? This in spite of a decade of financed-based, securitized, reflationary policies in the U.S. led by the public and private sector and a declining dollar. Hmmmmm?

In addition, Fed policy has for years focused on “core” as opposed to “headline” inflation, a concept actually initiated during the Nixon Administration to offset the sudden impact of OPEC and $12 a barrel oil prices! For a few decades the logic of inflation’s mean reversion drew a fairly tight fit between the two measures, but now in a chart shared frequently with PIMCO’s Investment Committee by Mohamed El-Erian, the divergence is beginning to raise questions as to whether “headline” will ever drop below “core” for a sufficiently long period of time to rebalance the two. Global commodity depletion and a tightening of excess labor as argued in El-Erian’s recent Secular Outlook summary suggest otherwise
