Worked away at and managed to stabilise prices? (6)
I believe the answer is:
pegged
'worked' is the definition.
The definition and answer can be both to do with contact as well as being past participle verbs.
Maybe they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for pegged that I've seen before include "(Of prices) held level" , "Scored (at cribbage)" , "Fixed (price) at particular level" .)
