The chart above (thanks to Olivier Ballou) is an update of a chart we produced last year about this time, and shows the percent changes since January 1997 in the prices of selected consumer goods and services, along with the increase in average hourly earnings in this version … Blue lines = prices subject to free market forces. Red lines = prices subject to regulatory capture by government. Food and drink is debatable either way. Conclusion: remind me why socialism is so great again.To which I reminded him of the Baumol cost disease and followed up with this.

I assumed that regulation, bloat and bureaucracy, monopoly power and the Baumol effect would each explain some of what is going on. After looking at this in depth, however, my conclusion is that it’s almost all Baumol effect.
