Threat Bargaining Games with Incomplete Information and Nash Solution

In this paper we extend the framework of threat bargaining games to include these with incomplete information. In this set up we address ourselves to two significant problems: 1) Under what conditions would ‘truthful’ revelation of the disagreement payoffs be a Nash equilibrium of the resulting threat bargaining game? 2) Obtaining a characterization of the Nash bargaining solution without the Independence of Irrelevant Alternatives Assumption.
