A fuzzy logic based bargaining model in discrete domains: Axiom, elicitation and property

This paper builds a multi-demand bargaining model based on fuzzy rules, and introduces its agreement concept, which satisfies four intuitive properties of consistency, collective rationality, disagreement and minimum concession. In the model, the fuzzy rules are used to calculate how much bargainers should change their preference during a bargaining. Moreover, the psychological experiment are used to elicit the fuzzy rules. In addition, we analyse how bargainers´ risk attitude, patience and regret degree influence agreement of our bargaining game, and identify the existence conditions of bargaining agreement.
