This paper studies the existence of expectations equilibria for message processes on stochastic exchange environments. A message process which permits the general existence of expectations equilibria is termed admissible. The main results are: (1) Every admissible process satisfies a weakened version of the Hurwicz "privacy" condition. (2) The competitive process is admissible, and has a message space of locally minimal size among admissible nonwasteful processes. (3) The only admissible condensations of the competitive process are constant functions.
