Abstract

We study efficiency in decentralized markets with aggregate uncertainty and one-sided private information. There is a continuum of mass one of uninformed buyers and a continuum of mass one of informed sellers. Buyers and sellers are randomly and anonymously matched in pairs over time, and buyers make the offers. We show that all equilibria become efficient as trading frictions vanish.
