Messed up CPI. - Bill Gross’s Investment outlook for June 2008
Posted by adesigar on May 23rd, 2008An excellent article by Bill Gross about how the FED is underreporting inflation. If you are a regular reader here you probably read this in my Article “Here’s a TIP buy TIPS” Bill Gross has an interesting chart in his article showing CPI composite for 24 countries. The article is a must read.
My simplified version of Bill Gross’ article is
Housing
The housing component of CPI is based on how much the house would rent for. The large increases in the cost of buying a home these last few years are not in the CPI since home prices went up but rent has not risen as much. Who cares that the majority of people own homes or want to buy homes, lets look at rent to reduce inflation numbers.
Geometric weighing and Substitution
Using geometric weighing, Goods and Services which increase in price are given lower weight because people would consume less of those goods and services. So if milk and bread increases in price the government assumes we will eat less milk and bread. Substitution outright replaces what you consume, it says if people cant afford Steak they will buy burgers so lets look at burger prices instead. CPI is supposed to calculate how much the costs increase to live the same quality of life. The current CPI calculates inflation for a deteriorating stand of living.
Core Inflation
So how do you top the brilliant ways to reduce inflation pointed out above? Use Core CPI. The fed and government use core CPI which ignores Food and Energy. Like i’ve said before I would like to see these people who do not eat, do not drink, do not drive or use electricity. The lower a persons income the higher the effect from Food and Energy. Someone on minimum wage or lower will spend 30-40% of his money on Food and Energy which the really wealthy might just spend 5%-10%.
I propose a solution, before becoming a fed governor the person has to live on minimum wage for 1 year. That should sort this out.
