Coalition formation under limited communication (Q1194262)

Given a finite set of players, we investigate coalition formation under restricted communication. One random ``call'' per player is allowed and coalitions form only after the calls, which unite subsets of players, one by one, are executed. This mechanism provides a simple model of bounded rationality. We characterize possible topologies of the induced communications networks. A cooperative game is defined on the set of coalitions admissible according to a call realization. Sch a game may have an empty core, but we demonstrate a restricted class of these games and a related communication game which have nonempty cores.
