Announcement wars as an equilibrium selection device

No 2009077, CORE Discussion Papers from Université catholique de Louvain, Center for Operations Research and Econometrics (CORE)

Abstract: This paper attempts to give a rationale to public announcements, so often observed in the real world, and to formalize the idea that they can be used as a form of equilibrium selection device when multiple equilibria arise. It also shows how announcements solve the problems of coordination failures as predicted by the empirical literature based on experimental studies
