A note on the fundamental theorem of exact aggregation

摘要: Abstract If individual i's demands for a commodity are function of prices, p, income Mi and vector attributes Ai, then aggregate demand is This paper derives the necessary sufficient conditions fi, F system functions gk(M1,…,MN,A1,…,AN) symmetric in M's A's such that can be written form F(p, g, (M1,…,Mn,A1,…,AN),…, gn(M 1,…,Mn,A1,… ,An)) all values its arguments.
