Interesting.

I’m used to thinking of inflation as a demand-side phenomenon. The Econ 101 explanation was something about money supply. More dollars in circulation, more thrown at any particular good.

It makes sense that a supply shock across a slice of the market would count as inflation, because people are substituting some kind of produce. What about an isolated shock? If it had somehow just been bell peppers, should it have counted as inflation?

I guess I’m saying the CPI isn’t necessarily wrong to bias downwards. A metric which didn’t account for substitutions would be a bit silly in its own ways.

I have to admit I strongly disagree on the basics of inflation, then. It is agreed that the price of any good is dependent on supply and demand. Inflation, being about the increase in price of everything, necessarily needs to be dependent on both supply and demand as well. Constraining the supply of everything will straightforwardly lead to a price increase of everything.

There are some examples in which ignoring substitutions entirely would be foolish, yes. But imo the CPI goes too far in the other direction.

No, no, we agree on the basics. It’s just not what I’m used to.
