Abstract

We study competitive equilibria in exchange economies when a continuum of goods is conflated into a finite set of commodities. The design of conflation affects the allocation of scarce resources among agents, by constraining trading opportunities and shifting competitive pressures. We also consider sufficient conditions for a decentralized equilibrium to be achieved merely by an appropriate conflation, absent prices.
