Negotiations in the real world have many features which tend to be ignored in policy modeling. They are often multilateral, involving many negotiating parties with preferences over outcomes that can differ substantially. They are also often multidimensional, in the sense that several policies are negotiated over simultaneously. Trade negotiations are a prime example, as are negotiations over en...

Business processes in open distributed environments such as the Web force users to interact with other parties be it users or companies even if they have never had any common transaction in the past. Policy-driven trust negotiations emerged in order to address these situations. But although many policy languages and protocols have been defined, the problem of deciding which credential disclosur...

Climate negotiation outcomes are difficult to evaluate objectively because there are no clear reference scenarios. Subjective assessments from those directly involved in the negotiations are particularly important, as this may influence strategy and future negotiation participation. Here we analyze the perceived success of the climate negotiations in a sample of more than 600 experts involved i...

Automated Multi-attribute Negotiation is an important and valuable mechanism in the Navy detailing system, in order to realize efficient, distributed and “Win-Win” matching. This report provides an extensive literature review of the existing research in Multiattribute Negotiations in the fields of Economics and Artificial Intelligence, discussing the motivation for multi-attribute negotiations,...

egotiations are believed to be an advantageous coordination mechanism for electronic markets that transcend the selling of commodities as well as for the coordination of complex interactions among organisations. However, most e-Commerce negotiation systems to date can only support price negotiations (dynamic pricing). This may be one of the reasons why current electronic markets struggle for ac...

The expression of contracts in computer readable form, and the development of automated tests for completeness and well-formedness of contracts, has opened the door to significant advances in automating contract negotiations. To meet the needs of automation, such negotiations must follow explicitly specified message-exchange protocols. But to meet the needs of the negotiating parties, these pro...

In the context of economy globalization, the need for globally distributed negotiations involving a high number of negotiators communicating through the Internet becomes an important business issue. In such negotiations, the amount of information describing the negotiation process is too high to be easily understood by humans. In this paper, a prototype negotiation support system adapted to mas...

On Feb 4, 2016, after 7 years of negotiations, representatives from the USA, Japan, and ten other countries signed one of the largest trade and investment agreements in years, the Trans-Pacifi c Partnership (TPP). The negotiations were closed to the public, who only glimpsed drafts of the agreement when they were occasionally leaked. The participants were heavily lobbied by major industries. An...

Negotiations, a model of concurrency with multi party negotiation as primitive, have been recently introduced in [5,6]. We initiate the study of games for this model. We study coalition problems: can a given coalition of agents force that a negotiation terminates (resp. block the negotiation so that it goes on forever)?; can the coalition force a given outcome of the negotiation? We show that f...

Electronic negotiations can range from simple offer exchanges to complex communicative acts concerning packages of products and services. In contrast to dominant approaches aiming at automating the negotiation process (e.g. auction models), we introduce the notion of negotiation support for human negotiators conducting complex electronic negotiations. The negotiation support system Negoisst for...
