I'm a little stuck... Click here to teach me more about this clue!

'from such economic policies' is the definition.
I can't judge whether this definition defines the answer.

'yankees in disarray' is the wordplay.
'disarray' is an anagram indicator.
'yankees'+'in'='yankeesin'
'yankeesin' anagrammed gives 'KEYNESIAN'.

Can you help me to learn more?

(Other definitions for keynesian that I've seen before include "monetary doctrine" , "Follower of John Maynard" , "One economist's" , "Economist" .)

I've seen this clue in The Irish Times.
