Teachers of Negotiation and Alternative Dispute Resolution can use negotiation exercises conducted via email to accomplish two main goals: as a pedagogical tool to illustrate the advantages and pitfalls of e-negotiations, and as a research tool to investigate specific hypotheses of interest. Assigning to students a negotiation exercise to be conducted via email (or other electronic means such as instant messaging) permits the researcher to examine the negotiation transcripts, which are often very revealing. Dividing students into groups and carefully manipulating the procedures or instructions for the negotiation allows the researcher to examine the unique influence of particular factors that may be at play in the negotiation, such as the relationship between the parties, the influence of making the first offer, anchoring on a specific figure and insufficient adjustment away from it, and techniques that build rapport over email, to name just a few. Negotiation teachers from different law schools can collaborate so that students from different law schools negotiate with one another via email. Conducting email negotiations with strangers permits the researcher to examine issues regarding escalation of negative emotion and deterioration of trust that often arise in negotiations in adversarial contexts.
