> I'd like to find numbers which illuminate how much of the inflation is caused by lack of supply for relatively inelastic commodities.
The SF Fed published a study a little while ago, "How Much Do Supply and Demand Drive Inflation?":
> Inflation has remained at levels well above the Federal Reserve’s inflation goal of 2% for over a year. Separating the underlying data from the personal consumption expenditures price index into supply- versus demand-driven categories reveals that supply factors explain about half of the run-up in current inflation levels. Demand factors are responsible for about one-third, with the remainder resulting from ambiguous factors. While supply disruptions are widely expected to ease this year, this outcome is highly uncertain.
