More specifically, this is the informational framework.
Nature selects a coordination game, out of two possible ones, and informs one of the two players.
The informed player sends this information to the opponent who, should she receive the message, in turn sends a confirmation. If the confirmation arrives successfully the informed player will send a confirmation of a confirmation and so on. Rubinstein s indication for a possible explanation of empirical evidence inconsistent with the result is that, since the proof of the main theorem is based on mathematical induction, people in reality might not use induction. Nash Equilibria may arise. Alternatively people heterogeneity , in so far as their communication abilities are concerned, may play a positive role in enhancing appropriate coordination.
