چکیده

Negotiations, a model of concurrency with multi party negotiation as primitive, have been recently introduced in [5, 6]. We initiate the study of games for this model. We study coalition problems: can a given coalition of agents force that a negotiation terminates (resp. block the negotiation so that it goes on forever)?; can the coalition force a given outcome of the negotiation? We show that for arbitrary negotiations the problems are EXPTIME-complete. Then we show that for sound and deterministic or even weakly deterministic negotiations the problems can be solved in PTIME. Notice that the input of the problems is a negotiation, which can be exponentially more compact than its state space.

Transfer of Bargaining Power Sources in Oil Trade Games

Bargaining Power is one of the important issues in oil trade negotiations. In this paper two effective factors in bargaining power i.e. patient time to deal and outside options of each player have been considered. The necessary relations for exchange of sources in negotiation have been derived.

Decision Support for Extensive Form Negotiation Games

This paper presents a tool, NEGEXT, for finding individual and group strategies to achieve certain goals while playing extensive form negotiation games. NEGEXT is used as a model-checking tool which investigates the existence of strategies in negotiation situations. We consider sequential and parallel combinations of such games also. Thus, it may aid students of negotiation in their understandi...

Detection of Negotiation Profile and Guidance to more Collaborative Approaches through Negotiation Games

Negotiation is an activity that involves complex human relationships which should be treated with great caution to prevent them from being injured or destroyed, ruining any future chances of further negotiations or agreements. Therefore, the improvement of negotiation skills is essential and an important part of this improvement is the discovery of one's negotiation profile. This paper presents...

Efficiency in Negotiation: Complexity and Costly Bargaining∗

Even with complete information, two-person bargaining can generate a large number of equilibria, involving disagreements and inefficiencies, in (i) negotiation games where disagreement payoffs are endogenously determined (Busch and Wen [4]) and (ii) costly bargaining games where there are transaction/participation costs (Anderlini and Felli [2]). We show that when the players have (at the margi...

Two-player preplay negotiation games with conditional offers

We consider an extension of strategic normal form games with a phase before the actual play of the game, where players can make binding offers for transfer of utilities to other players after the play of the game, contingent on the recipient playing the strategy indicated in the offer. Such offers transform the payoff matrix of the original game but preserve its non-cooperative nature. The type...

Complexity and Efficiency in Repeated Games with Negotiation

This paper considers the “negotiation game” (Busch and Wen [4]) which combines the features of two-person alternating offers bargaining and repeated games. Despite the forces of bargaining, the negotiation game in general admits a large number of equilibria some of which involve delay in agreement and inefficiency. In order to isolate equilibria in this game, we explicitly consider the complexi...
