Alex Williams recently wrote “What Is ‘Core PCE Services Ex-Housing’ Anyway?,” which dissects the measure that the Fed is using to get a handle on “underlying” inflation. The most interesting bit (for me) is that about 1/4 of this measure is an imputed price index, based on wages. This means that this component will track wages (giving a convenient analytical relationship) by definition.
The more I know about inflation the more I realise I know nothing about it
