This paper establishes that the competitive allocation process is the only informationally decentralized mechanism for exchange environments which (i) achieves Pareto optimal allocations; (ii) gives each consumer an allocation which is, according to his preferences, at least as good as his endowment; (iii) satisfies certain regularity conditions; and (iv) has a message space of the smallest dimension necessary to satisfy (i-iii).
