Supporting Interactive Multi-Attribute Electronic Negotiations with ebXML

The inter-organizational character of electronic negotiations raises social, legal, organizational and technical research questions. One of the main weaknesses of electronic negotiation applications today is that they do not sufficiently take into consideration the integration requirements that stem from the latter two of these aspects. Our objective is to design and build an electronic negotiation application that complies with these requirements. A major task within this work is the modeling and specification of the negotiation process and negotiation objects. To meet the integration requirements, the use of standards is essential. In our paper, we apply the ebXML framework to the task of modeling interactive bilateral multi-attribute electronic negotiations. For this purpose, we introduce the negotiation process flow underlying our application scenario. We explain the significance of ebXML for standardized business transaction modeling. We develop ebXML process and object definitions and suggest modifications of and additions to the current ebXML standard. Finally, we discuss the scope and the limitations of our concept and prototype.     

The Montreal Taxonomy for Electronic Negotiations

Research in the domain of electronic negotiations is a rather new and very interdisciplinary field, which gains more and more attention due to the industry hype and momentum regarding electronic commerce and electronic markets. Negotiations in a narrow sense (not taking into account simple forms such as hit and take) have been identified as an advantageous coordination mechanism for the interaction of buyers and sellers in electronic markets that transcend the selling of commodities or uniform goods. Hence, support for negotiations may become a critical success factor for electronic markets, especially regarding the recent failures of many industrial ventures. This paper presents the Montreal Taxonomy, which allows not only for the exact characterisation and comparison of a broad variety of electronic negotiation designs and systems, ranging from auctions to bilateral bargaining tables, but could also lead towards a more structured approach for the design of electronic negotiations.     

Two-Party Negotiation Modeling: An Integrated Fuzzy Logic Approach

Game theoretic models attempted to predict unique equilibrium outcomes of negotiations with limited success. The imprecise character of negotiation is often altered to fit the game theorist's exacting approach. Alternative models deviated from the formal game theoretic approach and attempted to accommodate concepts such as negotiator power and time pressure. In this paper, we introduce a model which uses a fuzzy logic approach to deal with the imprecision in the negotiation process and to integrate several negotiation theories. The new model is used to simulate multiple-issue, two-party negotiations and results are consistent with established negotiation theories.     

Design and Implementation of Business Objects for Automated Business Negotiations

In recent years, there has been increasing interest in the specification, generation and exchange of business objects in the context of electronic commerce. Common business objects have been defined for product catalogs, purchase orders and other business entities. However, no business objects have been defined and implemented for supporting automated business negotiations even though business negotiation is very much an integral part of business activities. In this work, we have designed and implemented a set of business negotiation objects for supporting the bargaining type of business negotiations. These objects define the operations and information contents needed for negotiation parties to express their requirements and constraints during a bargaining process. They correspond to a set of negotiation primitives, which is a superset of the negotiation-related primitives defined in two popular languages: ACL and COOL. The implementation of these objects is patterned after the business object documents in the XML format proposed by the Open Applications Group, thus conforming to the established standard. The incorporation of several types of constraint specifications in these business negotiation objects provides the negotiation parties and the negotiation servers that represent them much expressive power in specifying callforproposals and proposals. Two synchronization problems and their solutions associated with the withdrawal and modification of negotiation proposals are addressed and presented in this paper. The use of these business negotiation objects in a bilateral bargaining protocol is also presented. We have validated the utility of these objects in an integrated network environment, which consists of two replicated negotiation servers, two commercial products, and some other university research systems that form a supply chain.     

B2B Negotiation Support: The Need for a Communication Perspective

Negotiation support is an important challenge for business-to-business e-commerce that is still poorly supported in current information systems. One reason is that negotiation processes are much harder to formalize than the business processes in the fulfilment phase. The goal of this paper is to provide the basis for a formal analysis of different types of electronic negotiations which can help developers of future negotiation support systems. The analysis is performed from a communication perspective, in particular, Habermas' theory of communicative action. Using this perspective, a distinction can be made between norm-oriented, goal-oriented and document-based negotiation. Whereas traditional modeling methods take a data-oriented view, the theory of communicative action supports a communication-oriented view that provides more insight in the logic of negotiation processes. The analysis forms the basis for the negotiation support prototype implemented within the ESPRIT project MeMo (Mediating and Monitoring Electronic Commerce) which was aimed at B2B e-commerce for SMEs in Europe.     

The Effects of Personalised Negotiation Training on Learning and Performance in Electronic Negotiations

Individuals have different learning styles and thus require different methods for knowledge acquisition. Whereas learning theories have long acknowledged this fact, personalised negotiation trainings especially for electronic negotiations have rarely been developed. This paper integrates learning styles and negotiation styles and reports on an implementation of this integration. We will discuss personalised negotiation trainings, namely an enactive training and a vicarious training, that we developed to match the learners’ learning styles. Such a matching is proposed to be beneficial regarding learning outcomes. Furthermore, positive effects on the dyadic negotiation outcomes are assumed. To this end, an experiment with participants from different European countries was conducted. The results show tendencies that personalised negotiation trainings lead to better skill acquisition during the training and also to fairer negotiation outcomes. Overall, this paper contributes an integration of the theories on individual differences from the domains of negotiation and learning as well as valuable insights for further experiments on individual differences in negotiations.     

E-Alliance: A Negotiation Infrastructure for Virtual Alliances

In this paper we provide an overview of E-Alliance, a software infrastructure we are developing to support negotiation activities in concurrent inter-organisational alliances. Our baseline is to offer a collaboration framework which fully preserves the autonomy of organisations grouped in an alliance, while enabling concurrency of their activities, flexibility of their negotiations and dynamic evolution of their environment. We propose to support negotiation between the partners within such alliances by combining different technologies, such as software engineering techniques, middleware-level coordination facilities and multiagent systems support. We present our approach in the context of a sample scenario of an alliance where partners are printshops capable of (out/in) sourcing print jobs among them to better accomplish their customers' requests.     

Hot Versus Cool Behavioural Styles in Electronic Negotiations: The Impact of Communication Mode

In this paper, we study the effects of synchronous and asynchronous communication mode on electronic negotiations. By applying content analysis, we compare the negotiation processes of two e-negotiation simulations conducted in a synchronous and an asynchronous setting. Our results show significant differences in communication behaviour of subjects. Synchronous negotiation mode leads to less friendly, more affective, and more competitive negotiation behaviour. In the asynchronous communication mode, negotiators exchange more private and task-oriented information and are friendlier. These results suggest that negotiators in the asynchronous mode, who have more time to reflect, cool down and control emotions better while negotiators, who communicate synchronously engage more in emotional and competitive “hot” debates. In addition, negotiators in the asynchronous mode are more satisfied with the process and outcome of the negotiation. We conclude that de-individuation and escalating effects might be caused by communication mode rather than by the ability of the media to transmit social cues.     

Qualitative representations of negotiations: Tutorial on a rule-based approach

This article introduces a logic-based approach for structuring and representing negotiation problems and for supporting negotiators. It is argued that rule-based formalism allows for integrating decision-making aspects unique and specific to negotiations with general reasoning mechanisms based on rationality postulates. The discussion of the rule-based systems and its application to negotiation modeling and support is preceded by an outline of qualitative and quantitative approaches to problem representation and reasoning, and an overview of predicate calculus. The advantages and disadvantages of rule-based systems and their ability to capture complex negotiation decision processes and reasoning are also given.     

Competition,Transparency, and Reciprocity: A Comparative Study of Auctions and Negotiations

The paper discusses experiments aimed at comparing multi-attribute reverse auctions and multi-bilateral negotiations for procuring goods with multiple attributes. Both exchange mechanisms involve a buyer purchasing from one of several sellers. Two types of negotiations are considered: verifiable and non-verifiable. They differ in the sellers’ knowledge of the current best offer on the table; in verifiable negotiations the best offer is automatically shown to every participant, which makes it similar to auctions. Online auctions and negotiation systems were used to study auction and negotiation processes, and the mechanisms’ efficiency. The results show that buyers did best using auctions, followed by non-verifiable and verifiable negotiations. We also looked into the differences between auctions and negotiations in terms of their duration, sellers’ and buyers’ involvement, and efficiency and conclude that the behavior of buyers and sellers cannot be explained solely on the grounds of traditional economics. It can, however, be explained on the grounds of social exchange theory and behavioral economics. In multi-bilateral negotiations competition and social behavior coexist. When transparency is introduced the social effect becomes stronger, weakening the impact of competition.     

On-line/Off-line: Joint Negotiation Teaching in Montreal and Vienna

E-business systems, the most recent generation of information systems, can be effectively used in teaching. One such system was developed and used in a collaborative project that involved teaching of negotiation theory and practice to students from Austria and Canada. The system provides customized course materials and a platform to conduct various e-negotiation activities. The design allows combining e-learning technologies designed to support students in their independent and individual learning with conventional face-to-face training. Our experience indicates that professional negotiation training accompanied by e-learning, and tools to support decision-making and negotiation can foster students' appreciation of the technology as well as demonstrate its limitations. The combination of technology-intensive and conventional resources contributed to students' awareness of social influences on negotiations, importance of communication, and focussed their attention on the problem and its solution. Deeper customization of the course content and delivery may further contribute to effective learning and acquiring of both communication and analytical skills.     

On automated e‐business negotiations: Goal,policy, strategy,and plans of decision and action

In recent years, there has been increasing interest in automated e‐business negotiations. The automation of negotiation requires a decision model to capture the negotiation knowledge of policymakers and negotiation experts so that the decision‐making process can be carried out automatically. Current research on automated e‐business negotiations has focused on defining low‐level tactics (or negotiation rules) so that automated negotiation systems can carry out automated negotiation processes. These low‐level tactics are usually defined from a technical perspective, not from a business perspective. There is a gap between high‐level business negotiation goals and low‐level tactics. In this article, we distinguish the concepts of negotiation context, negotiation goals, negotiation strategy, and negotiation tactics and introduce a formal decision model to show the relations among these concepts. We show how high‐level negotiation goals can be formally mapped to low‐level tactics that can be used to affect the behavior of a negotiation system during the negotiation process. In business, a business organization faces different negotiation situations (or contexts) and determines different sets of goals for different negotiation contexts. In our decision model, a business policymaker sets negotiation goals from different perspectives, which are called goal dimensions. A negotiation policy is a functional mapping from a negotiation context to some quantitative measures (or goal values) for the goal dimensions to express how competitive the policymaker wants to reach that set of goals. A negotiation expert who has the experience and expertise to conduct negotiations would define the negotiation strategies needed for reaching the negotiation goals. Formally, a negotiation strategy is a functional mapping from a set of goal values to a set of decision‐action rules that implement negotiation tactics. The selected decision‐action rules can then be used to control the execution of an automated negotiation system, which conducts a negotiation on behalf of a business organization.     

WTO电子商务谈判与数字贸易规则博弈

2019年1月,76个WTO成员签署《电子商务联合声明》,确认启动与贸易有关的电子商务议题谈判,旨在制订电子商务/数字贸易领域的国际规则。本文在对谈判成员、提案内容和规则议题进行梳理的基础上,研究分析了数字贸易规则博弈焦点和国家间立场分歧。研究发现:从成员构成看,发达经济体是谈判的主导者,发展中经济体参与谈判和提交提案的比例偏低;从议题设计看,谈判内容远超以往电子商务谈判,更多聚焦于跨境数据流动、源代码披露等数字贸易规则议题;从博弈焦点看,谈判核心包括数据要素、市场空间、监管治理、技术发展与收益分配5个方面,发达经济体和发展中经济体的诉求差异巨大。在此形势下,中国既要加快完善国内体制机制,营造有利于数字经济和数字贸易发展的环境,又要积极参与数字贸易国际规则制订,提出中国规则主张。     

The Effects of Multimedia Communication on Web-Based Negotiation

With the rapid growth of electronic commerce, there is growing demand forremote online negotiations. Although the Internet now enables audio and video communication, most Web-based negotiation systems are still text-based. There is, however, a lack of research on the effects of multimedia on remote negotiations. In this paper, we present a theoretical model to investigate the impacts of multimedia communication in an online negotiation setting. The constructs in our model include communication efficiency, communication effectiveness, and positive and negative social-emotional communication. Through a simulated house purchasing negotiation experiment, we study how different multimedia combinations (text only; text with audio; text with audio and video) affect our constructs and thus further influence negotiation results. Our results showed that both text with audio and text with audio and video communication were significantly preferred to text alone. However, the addition of video to text and audio communication in a negotiation environment was not found to be beneficial. It did not significantly improve communication efficiency, effectiveness or positive social-emotional communication, but distracted negotiators from focusing on the negotiation task. Our analysis also revealed that the communication efficiency construct did not correlate with the perceived success of the negotiation solution; however communication effectiveness and social-emotional communication did correlate with negotiation satisfaction.     

Evaluations of Tactics for Automated Negotiations

Automated negotiation under the infrastructure of e-commerce is becoming an important issue. However, although the communication protocols and frameworks of automated negotiation have been extensively investigated, the corresponding tactics and strategies are still underdeveloped and need to be evaluated further. Based on the negotiation model proposed by Faratin et al., this paper examines the performance of automated negotiation tactics and intends to provide concise suggestions for the users of automated negotiation. First, theoretical analysis is used to evaluate the behavior-dependent tactics. Constructive conclusions are obtained when single-issue negotiations are considered. Next, a new framework for applying single-issue tactics to multi-issue negotiation is proposed. Based on this framework, theoretical analysis is then extended to multi-issue cases. Finally, different from the previous work, exhaustive simulations based on two-issue negotiations are performed to evaluate the effectiveness of behavior-dependent and time-dependent tactics. The experimental results provide several important insights into negotiation tactics.     

An Experimental Investigation of Virtual Negotiations with Dynamic Plots

Advanced information and communications technologies provide the basis for virtual negotiations where competitors continuously alter their assignments in real-time in response to market changes. Dynamic plots, which depict the competitors' possible profits and hints for how to improve them, provide a way to support these types of negotiation settings. This research reports on an experimental assessment of dynamic plots for visual interactive negotiations. Dynamic plots are compared to an alternative dynamic method of real-time negotiation support using selected conflict situations to test five hypotheses. The results of the laboratory assessment provide evidence for the hypotheses that dynamic plots stimulate negotiations, provide effective support to reach efficient, system optimal, and equitable solutions, and are well received as negotiation tools in real-time settings.     

A Gender Analysis of Bank Loan Negotiations in Uganda

This paper highlights the differences between men and women in bank loan negotiations. It presents findings of an ex post facto design study that involved administering questionnaires to 289 respondents who had ever applied for a loan from a Ugandan commercial bank from 1999 through 2005. Results showed that male and female respondents differed in their negotiation behavior and outcomes. Female respondents scored higher than male respondents on self-enhancement and yielding. Male respondents scored higher than female respondents on inaction. Results further showed that female respondents receive lower payoff than male respondents from bank loan negotiations, and that both male and female respondents encounter problems in mixed gender negotiations.     

模拟谈判法在国际商务谈判教学中的应用研究

模拟谈判法是在国际商务谈判实践教学中行之有效的教学方法之一。模拟谈判法的实施过程包括选择模拟谈判案例、合理分组、模拟谈判前的准备工作、实施模拟谈判、教师点评与总结、谈判报告的完善与提交六大步骤。目前的模拟谈判教学实践在课程设置、教学条件、学生掌握程度和运用能力等方面仍存在问题,应从建立专门的谈判室、提高教师的综合水平、加强英语在模拟谈判中的使用、提高实训考核所占比例等方面加以改善。
