Forget The CPI, Use This Index and Profit From This Sector

"Most Americans in 2011 experienced a day-to-day inflation rate of 7.2 percent-more than two times the official estimate released by the Bureau of Labor Statistics." -- AEIR

The American Institute For Economic Research (AIER) has done investors and consumers an important service. They have compiled an index that actually reflects the way we live, eschewing the government's "hedonic quality adjustments" (that's when they basically say, "Well, yes, dresses cost more this year, but since the buttons are of better quality, we adjust that increase downward") or the "owners' equivalent rent" in lieu of home prices, and all the other little tricks of the trade that too often render the CPI the equivalent of the punch line of the old accountant joke: "4 + 4? How much do you want it to be?"

The CPI is used to determine Cost of Living Adjustments and other yardsticks that determine how and when people living on a fixed income get an increase. It affects other interest rates as well as banks' willingness to lend at reasonable rates or pay their depositors a fair rate. The problem is, while I imagine the Bureau of Labor Statistics tries to measure things right, it probably doesn't measure the right things.

Take a senior couple living on a fixed income; they typify the consumers who most clearly need a realistic cost of living adjustment from the Social Security they paid into over their lifetimes, or their company pensions, or the CDs, bonds and preferreds they buy for a little extra income boost. And the CPI often understates real inflation and keeps all these savings rates artificially depressed.

On the other hand, the CPI measures a lot of things many people buy only occasionally. Using our senior couple as an example, they may not drive as much as they used to. Maybe they only put 8,000 miles a year on their car instead of the 15,000 they might have more typically driven when traveling on business or taking more frequent road trips, etc. It seems reasonable they might keep their car for ten years instead of five. Yet the CPI measures the cost of automobiles as if they were an annual purchase. This same couple might have their home fully paid for. "Owners' equivalent rent" isn't their issue. Their appliances work every bit as well as they did five years ago so they aren't likely to rush out and buy new ones. Yet the CPI treats appliances and furniture as if we all are in a mad dash to replace the contents of our home rather more frequently than we really are.

The EPI developed by AEIR, on the other hand, reflects basic economic change that we all see every day. Here's a chart that shows the rate of increase in the CPI over the past quarter-century. The green line shows the EPI, presenting a very different picture, the picture every American feels in their wallet and knows in their heart to be reflective of our daily living.
