With one exception, Tony Yates strikes me as being a very sensible and very good money/macro economist. But at the mention of "helicopter money", he seems to turn into an Old Testament prophet, or maybe Private Frazer from Dad's Army, saying "We're doomed, I tell ye!" (or maybe this longer video makes my point better). (That's my payback for Tony calling us Market Monetarists a bunch of trainspotting anoraks!)
Here's Tony: "I am left being prepared to concede that helicopter drops might generate inflation, but not that they would be beneficial, since they may lead to the steady destruction of that money altogether with all the attendant costs."
If we were indeed "doomed" by helicopter money, we would be long dead. In fact, we are doomed by not doing helicopter money. Doomed to communism!
