I'm trying to remember where I heard this from, but I found this idea pretty useful. Mainly because I know what inflation is, but I didn't spend enough time thinking about what it means and what it tells me. > Inflation is simply the delta between a past price and the current one, over a set of goods / services, which we represent using an average of some kind, usually ignoring certain kinds of price changes. For example some inflation measures ignore rent. > It would be useful to have every measure of inflation cite the raw vector (which would be good to standardise) as well as listing what it excludes visibly. > The underlying vector would show us much more, such as are all prices increasing / decreasing? Are some going in the opposite direction? This would give us space to have a more nuanced discussion about causes and how much weight they may have. Mistakes / errors in recollection are my own =)...
