Started up in here again. Apparently a long one tonight. Had a small lunch, no supper. Hungry. Going to talk with group about paper after.
Consumer Price Indexes are measures of change in price levels. Mainly measures inflation. There’s a core CPI, and a headline CPI. Core does not include food or energy costs. Headline CPI includes everything.
There’s also the Personal Consumption Expenditures price index. This is weighted based on chained dollars.
