A novel approach to the generalisation of the conflict generating effe
cts of product price changes on household incomes and utilities is dev
eloped. It is based upon the concepts of household production of goods
and complementarities in production between households. Economy outpu
ts are imputed to households. The imputed household outputs may be pos
itive or negative. Households have an incentive to supply factors to f
irms if and only if at least one imputed output is negative. It is sho
wn that households which are complementary in production are competiti
ve in distribution. The results are generalised to economies with incr
easing returns to scale industries.
