In negotiation, opening offers affect negotiated agreements. Across various negotiation settings, negotiators' outcomes are monotonically related to initial offer values (Chertk-Abstract Applying a multi-issue integrative negotiation scenario, we explored the relationship between negotiators' internal external (I-E) locus of control orientations, initial offers, and final negotiation outcomes. Focusing on the noninitiating party, we found that the degree to which initial offer recipients were internally versus externally oriented moderated the extent to which their final outcome was influenced by the initial offer they received. In comparison to externally oriented initial offer recipients, internally oriented recipients were less influenced by the proposed initial offer and managed to obtain more self favorable negotiation outcomes. This outcome advantage was due to the fact, that independent of the I-E orientation of the other negotiating party, internally oriented recipients reached agreements with higher total joint pie than externally oriented recipients and also managed to maintain a fair share of the pie.
