Title: Renegotiation and Coordination with Private Values (Joint with 
Christoph Kuzmics)
Abstract:
We study coordination games with pre-play communication in which agents 
have private preferences over the feasible coordinated outcomes. We 
present a novel intuitive equilibrium strategy with the following 
properties: (1) each agent reports his preferred outcome (and nothing 
else), (2) agents never miscoordinate, (3) if the agents have the same 
preferred outcome, then they coordinate on this outcome, and (4) 
otherwise, there is a “fallback norm” that determines the coordinated 
outcome. We show that this behavior is essentially the unique 
renegotiation-proof strategy, and that it satisfies appealing 
properties: independence of the distribution of private preferences, 
Pareto optimality, high ex-ante expected payoff, and evolutionary 
stability.
