In distribution of income the company is thrifty (8)
I believe the answer is:
economic
'thrifty' is the definition.
(thesaurus)
'in distribution of income the company' is the wordplay.
'in' means one lot of letters goes inside another.
'distribution of' is an anagram indicator.
'the company' becomes 'co' (abbreviation).
'income' anagrammed gives 'enomic'.
'enomic' enclosing 'co' is 'ECONOMIC'.
'is' is the link.
(Other definitions for economic that I've seen before include "system of money" , "viable" , "Using the minimum resources necessary for effectiveness" , "Justified in terms of profitability" , "Productive: financially sound" .)
