Consumer choice starts to move economic numbers up (4)
I believe the answer is:
menu
'consumer choice' is the definition.
'menu' can be an answer for 'choice' (I have seen 'Choice of dishes' mean 'menu' so perhaps 'choice' could also mean 'menu'). I am not sure about the 'consumer' bit.
'starts to move economic numbers up' is the wordplay.
'starts to' says to take the initial letters.
The initial letters of 'move economic numbers up' is 'MENU'.
Can you help me to learn more?
(Other definitions for menu that I've seen before include "List of items available in restaurant (4)" , "Cafe's list" , "List of dishes available in restaurant" , "List of food items on offer" , "List of dishes offered by restaurant" .)
