A REMARK ON THE EQUILIBRIUM SET OF PURE EXCHANGE ECONOMIES

We present a unified mathematical framework within which, among others , pure exchange economies with a finite set of agents, as well as thos e with a continuum of traders may be studied simultaneously. We prove that the reasoning presented by Balasko (1975) on the equilibrium set for finite economies generalizes very naturally to our setting. His re sults may therefore be recovered as a special case of those presented in this note.
