We consider a game where one player, the Announcer, has to communicate the value of a payoff relevant state of the world to a set of players who play a coordination game with multiple equilibria. While the Announcer and the players agree that coordination is desirable, since the payoffs of the players at the equilibria are unequal, they disagree as to which equilibrium is best. We demonstrate experimentally
that in such coordination games, in order to mask the asymmetry of equilibrium payoffs, it may be advantageous for a utilitarian benevolent Announcer to communicate in an ambiguous or vague manner. (JEL C71, D81, D83)
