Concern about one shabby economic period (6,4)
I believe the answer is:
fiscal year
'period' is the definition.
(fiscal year is a kind of period)
'concern about one shabby economic' is the wordplay.
I cannot quite see how this works, but
'about' could be 'ca' (circa) and 'ca' is present in the answer.
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
