The purpose of this research is to search for a more inclusive construct that can integrate the studies of offers in bargaining with other communicative strategies and tactics. Focusing on the perceived persuasiveness of offers, a construct of "offer rhetoric" has been proposed , by which the behavior of offer was redefined as only a speech act but a rhetorical act. Twelve “offer rhetoric” tactics have been found from the literature of negotiation including evidence quality, evidence number, long-termed relationship, mutual trust, time pressure, constituency pressure, objective criteria, face need, procedure justice, concession magnitude, concession frequency, and historical judgment. As a result of factor analysis, four types of offer rhetoric strategies are identified in this research—traditional bargaining, communicative qualities, relationship-oriented, and negotiation competence. Additionally, the relationships between these four types strategies and concession-making behaviors under integrative bargaining situations and distributive bargaining situations are examined by interviewing 147 negotiators.
