A fixed-point property of logic-based bargaining solution

Abstract. This paper presents a logic-based bargaining solution based on Zhang and Zhang’s framework. It is shown that if the demand sets of players are logically closed, the solution satisfies a fixed-point property, which says that the outcome of bargaining is the result of mutual belief revision. The result is interesting not only because it presents a desirable logical property of bargaining solution but also establishes a link between bargaining theory and multi-agent belief revision.
