There isn't 1 kind of economic crisis. Monetary expansion works well when you're dealing with a credit crunch, but it doesn't work great when your issue is lack of supply.
name a country that did monetary expansion during a credit crunch and also didn't do monetary expansion when there was a lack of supply. Note my bar is low: In "classical keynesian" theory, there should be monetary contraction during lack of supply, but I REALLY don't recall any country just "burning" reserves (deleting zeros off of ledgers at the biggest banks).
