Glancing at the graphs, I thought it was weird his alternate CPI exactly tracks BoL CPI changes. Turns out it’s because he’s just adding a constant. From Wikipedia: > Shadowstats does not actually recalculate BLS data, rather, the Shadowstats CPI merely adds a constant to the officially reported numbers This doesn’t inspire much confidence in his alternate CPI. MIT’s billion prices project is much more novel and interesting. They track prices from online goods in real-time to calculate price inflation.
