Core inflation, which excludes the effect of food and energy prices and is how every self-respecting economist measures price increases, is up 8.75% over the past five years. However, as ConvergEx’s Nick Colas notes, this is a poor indicator for the true cost of living for many Americans. Having scrubbed the data, Colas has found the top 10 items that appreciated the most from 2008 to 2013 and the 10 items that became substantially less expensive, according to the government’s Consumer Price Index (CPI). The data is deceiving though, as the CPI’s “hedonic quality adjustment” distorts the amount of money people actually spend. Even more importantly, Colas warns, things that have a relatively low weighting in the CPI and that people use selectively – such as healthcare and education – don’t have a big impact on the core number, but represent considerable expenses for many Americans. Thus we must use caution when using one figure to make policy decisions for an entire nation, and consider what happens to inflationary expectations if and when the still-sluggish economic recovery finally finds second gear.
