■ Within the last decade, the significance of electronic interaction in organizations has increased substantially. Managing difficult situations and conflicts via e-mail, chat, or more sophisticated communication technologies is a daily business for managers in international organizations. Therefore, electronic negotiations, the terminus technicus for computer-mediated communication processes, aimed at reaching mutually beneficial solutions for conflicts, require more attention of scholars as well as practitioners. The purpose of this paper is to gain insight into e-negotiation processes helping to better understand how conflict can be resolved when interpersonal cues are not at hand. We conducted a laboratory experiment and applied content and phase analysis to transcripts of electronic negotiations. As negotiation theory suggests, we find two distinct phases, a differentiation phase followed by an integration phase. Within the two phases, there is a shift in strategic function, i.e. from providing information in the differentiation phase towards strategic action in the integration phase. Moreover, negotiation behavior can also be mapped in a more differentiated four-phase model. Special emphasis is put on the effect of prior negotiator relationship in two conflict settings. Our results show that negotiators who personally know each other manage conflicts with high intensity better and therefore reach an agreement more often. Recommendations for electronic negotiations are discussed based on the results.
