ABSTRACT
It is argued that a negotiator's fixed-pie perception, cooperative motivation, problem-solving behavior, and integrative outcomes are influenced by the content of the negotiation-the conflict issue. Negotiation involves conflicting interests, conflicting ideas about intellective problems, or conflicting ideas about evaluative problems. Study 1 showed that individuals in a negotiation about interests have a stronger fixed-pie perception and have a lower cooperative motivation than individuals in an evaluative negotiation, with intellective negotiations taking an intermediate position. Study 2 showed that individuals in a negotiation about interests made more trade-offs and reached higher joint outcomes than individuals in an intellective or evaluative negotiation. Study 3 replicated this finding in a field study. The studies bridge insights from negotiation research and decision-making research and show that the conflict issue has important effects on the negotiation process. Copyright 2000 Academic Press.
