I would categorize it differently. Rather than just objecting to their policy, he is describing a reason why current policies are suboptimal, and suggesting ways that current policies could be improved. Namely, that domestic central banks around the world don't coordinate policy with foreign central banks, despite the existence of major feedback loops between foreign and domestic policy. He hypothesizes that the world economy would be better off if there were more global coordination on monetary policy.
And we all saw hoe that approach, in a much more contected system for sure, worked during the Euro crisis. Funny how we survived this and the EU isn't a ruined shambles.
We just ruined average peoples lives in the southern part, especially Greece, in order to save the big banks.
To be fair, he's an economic historian. I am the OP and thought that this was a really interesting article on inflation, sorry that you don't agree.
There are worlds between a BA in economics being an economic historian and an expert in monetory policy. If Covid tought me something, it is listening to those doing it, or directly advicing those doing it, instead of all those people regardless of who they are, that obly stand at the sidelines.
