Business studies and remakes charter arrangements (6,8)
I believe the answer is:
market research
'business studies and' is the definition.
I can't tell whether this definition defines the answer.
'remakes charter arrangements' is the wordplay.
'arrangements' indicates an anagram (I've seen 'arrangement' mean this).
'remakes'+'charter'='remakescharter'
'remakescharter' anagrammed gives 'MARKET RESEARCH'.
Can you help me to learn more?
(Other definitions for market research that I've seen before include "Consumer studies" , "Study of consumers' needs and preference" , "retail study" , "study of consumer needs" , "test of customers' requirements" .)
