In this chapter, we evaluated the status of previous negotiation research—which has focused almost exclusively on market-exchange relationships—and evaluated its status for different types of relationships, particularly communal- sharing and authority-ranking relationships. Within relationships, we see that parties shift their focus considerably, moving away from a sole focus on price and exchange to also attend to the future of the relationship, including the level of trust between the parties and questions of fairness, and to build strong positive reputations. We argue that most negotiations occur within these relationship contexts, and future work must attend to their unique complexities.
