Yields return in closed economy (5)
I believe the answer is:
cedes
'yields' is the definition.
(I know this)
'return in closed economy' is the wordplay.
'return' says the letters should be written in reverse.
'in' indicates a hidden word.
'sedec' can be found hidden inside 'closed economy'.
'sedec' reversed gives 'CEDES'.
(Other definitions for cedes that I've seen before include "Yields, hands over" , "Surrenders or yields" , "Hands over formally" , "Gives way" , "Gives in, relinquishing" .)
