Manipulation Of CPI Saved The Federal Government Over $150 Billion From 1998-2012

For the government to be commended on “saving” for cheating on the CPI by robbing the people, is to say it’s alright to shoplift with a gun, but only candy.

Cost-of-living adjustments increase entitlement spending automatically every year. Most COLA’s use all or part of the CPI to calculate inflation. The US further embeds the CPI in the system by indexing a growing portion of its government debt via TIPs. Even welfare benefits like food stamps use applicable indices within the all-items CPI to calculate COLA.

In total almost $3 trillion of federal yearly liability is subject to automatic annual CPI-based increases. This calculation includes:

  • All yearly means-tested welfare benefits subject to a COLA (e.g. SNAP, NSLP, etc…)
  • All yearly social security spending (e.g. SSI, OASI, DI, everything…)
  • All outstanding TIPs balance (every year the principal of an outstanding TIP is adjusted up/down by the inflation rate)

This time series represents the majority of yearly federal obligations that are subject to inflation-based COLA increases. We can thus attempt to calculate how much the government saved each year through methodological changes to the CPI. By the government’s own reckoning:

[The] improvements made by the BLS have reduced the measured
increase in the CPI… The combined effect of the changes made through 1998 has been to lower the CPI inflation rate by 0.44 percentage point per year. Changes to be implemented in 1999 and 2000 will lower CPI inflation by a further 0.20 and 0.04 percentage point per year.

– Economic Report of the President Feb 1999 pg 93

Thats a total of 0.68% a year from 2000 onward. While this might not sound like a lot, given the immense sums of money the government owes the public, this adds up to billions of dollars in savings:

applies 0.0068 deflation rate to total amount calculated above

That adds up to a total savings of $150,147,988,800. Again, this is basing our deflation rate at 0.68% from the economic report referenced above. There is considerable evidence, however, that the real effect of quality adjustments on the CPI is much higher.

Using the more realistic divergence of 1-2% we saw from the BPP data puts the total savings at the $200-$400 billion range. 

In the investigation of any crime, it is important to find motive:

  • When a seemingly trivial change to a statistical index can potentially deprive taxpayers of hundreds of billions of dollars 
  • When an agency keeps raw data hidden from outside inspection (BLS deems raw pricing data as confidential and thus exempt from FOIA)
  • When a government cannot make the unpopular decisions necessary to reign in entitlement spending

Then you are in a time where an executive branch might take actions into its own hands in the name of efficiency. Hiding in econometric obscurity, in an area of research so boring no economist would dare tread, did the government knowingly encourage the adoption of a dubious economic theory that would likely bias inflation downward? If so, it was a good bet.
