Negotiation support using the Decision Support System GMCR

The Graph Model for Conflict Resolution constitutes a unique and flexible approach to the representation, analysis, and understanding of strategic conflict. This methodology, as implemented in the Decision Support System GMCR, constitutes a useful tool for negotiation support. Because GMCR includes efficient algorithms for calculating the stability of states, it encourages extensive comparisons of the consequences of different models of negotiators' decision making. GMCR also facilitates modifications to the way in which the conflict is represented, encouraging sensitivity and what-if analyses. The applicability of GMCR to negotiations is discussed in general, and in the context of a specific case study in environmental conflict resolution.     

Negotiation support using the Graph Model for Conflict Resolution

The Graph Model for Conflict Resolution is a flexible methodology for systematically studying strategic conflicts in the real world, and is therefore a natural tool for negotiation support. The basic definitions underlying the graph model are reviewed, and the techniques for analysis and interpretation are discussed. The modeling and analysis of a case study, an international trade negotiation concerning the export of Canadian softwood lumber to the United States, are used to demonstrate the practical application of the Graph Model for Conflict Resolution as a negotiation support tool. The modeling and analysis is carried out using the GMCR software system. The ability of the Graph Model for Conflict Resolution to provide insights and advice to negotiators is emphasized.     

Electronic Meetings and Intense Group Conflict: Effects of a Policy-Modeling Performance Support System and an Audio Communication Support System on Satisfaction and Agreement

Ad-hoc decision teams were used to examine the effects of an electronic meeting system (EMS) on group satisfaction and agreement. The decision task provoked intense conflict of values. The EMS had two core features - a policy-modeling group performance support system (incorporating structured decision methods and computer-supported cognitive feedback using Multi-Attribute Utility Analysis and Social Judgment Analysis), and an audio-based group communication support system (allowed dispersed members to communicate by voice). Policy groups reached higher agreement than conventional decision-making groups, apparently due primarily to the structure for cognitive-conflict tasks that was imposed on group discussion rather than computer-supported cognitive feedback displays. Audio groups were more satisfied with the conflict process than face-to-face groups. Decision agreement was equivalent across the two media. These audio effects for a highly equivocal task represent a further challenge to media richness theory.     

A Multi-Attribute Negotiation Support System with Market Signaling for Electronic Markets

Despite the rapid growth of technology and Internet-based markets, many of the current systems limit themselves to price as the single dimension variable and offer, if at all, only minimal negotiation support to the consumer. In the real world, commercial transactions take into account many other parameters both quantitative and qualitative such as product quality, speed, reputation, after sales service, etc. This paper discusses how these multiple attributes can be captured to augment standard negotiation processes in order to support electronic market transactions. Using a combination of utility theory and multicriteria decision-making, we propose heuristic algorithms to discover potential trades. In addition, the approach is included within a larger framework that incorporates market-signaling mechanisms. This not only allows for the systematic evolution of negotiation positions among buyers and sellers but can ultimately lead towards improving both market transparency and efficiency. To illustrate the multiple criteria model coupled with the dynamic market signaling framework, we report in this paper the implementation of a Web-based clearinghouse that serves the real estate market.     

Computer-Assisted Negotiations of Water Resources Conflicts

This paper describes the algorithms within and results obtained using an interactive computer program developed to assist those involved in negotiating agreements among parties having conflicting objectives. This Interactive Computer-Assisted Negotiation Support system (ICANS) can be used during the negotiation process by opposing parties or by a professional mediator. On the basis of information provided to the program, in confidence, by each party, it can help all parties identify feasible alternatives, if any exist, that should be preferred to each party's proposal. If such alternatives do not exist, the program can help parties develop counter proposals. Through a series of iterations in which each party's input data, assumptions, and preferences may change, ICANS can aid each party in their search for a mutually acceptable and preferred agreement. This paper describes the algorithms used for analyzing preferences and for generating alternative feasible agreements. Also presented a re the results of some limited experiments involving water resource system development and use conflicts that illustrate the potential of programs such as ICANS.     

Negotiation Support and E-negotiation Systems: An Overview

With negotiation being an often difficult process involving complex problems, computer-based support has been employed in its various phases and tasks. This article provides a historical overview of software used to support negotiations, aid negotiators, and automate one or more negotiation activities. First, it presents several system classifications, including implemented models, system architectures, and configurations of various systems interacting with human negotiators. Then, it focuses on NSSs (negotiation support systems) and related systems introduced in the early 1980s and on ENSs (e-negotiation systems), which are deployed on the web. These broad categories are discussed from four perspectives: real-life applications, systems used in research and training, research results, and research frameworks.     

An ESD Computer Culture for Intercultural Problem Solving and Negotiation

Intercultural problem solving and negotiation involves interaction of two or more cultures. These processes may be formally modeled using the Evolutionary Systems Design (ESD) framework implemented by appropriate computer group support systems (GSS). The ESD/GSS combination provides an ESD computer culture for intercultural problem solving and negotiation in a same place/same time or telework mode. With this, players in a multicultural group can be computer supported in generating and formally representing an evolving common culture (a situational culture) with regard to the specific problem at hand - an intercultural evolving group problem representation and solution. At the same time, the ESD computer culture provides an operational cybernetic/self-organization framework for the empirical study of cultural emergence in a multicultural group. This paper uses and develops work by Shakun (1996b).     

A framework for thinking about Group Decision Support Systems (GDSS)

Strategic problem solving in organizations is a social process that disturbs established social relationships. Maintaining a negotiated social order is crucial to political feasibility and to emotional commitment from the participants in relation to a solution package. However, Group Decision Support Systems that attend overly to managing social order risk group think through bounded vision. This may be avoided if emotional commitment is also encouraged through participants experiencing the problem situation from multiple perspectives and in relation to alternative solution strategies. Commitment depends upon both means/ends rationality and procedural rationality. This acknowledges the balance in providing support to a group with respect to the negotiation of social order, with the more traditional group decision support for socially negotiating order out of the problem situation. This article argues that effective Group Decision Support Systems must attend to both aspects of creating order. OR modelling methods and the support that can be provided by modern micro-computers offer a new way forward—models can be toys that a group can play with together, enabling them to create knowledge as well as use it.     

An empirical study on the effects of an enterprise fan page

Most major enterprises have invested in social networking to provide services, promote products, or communicate with customers. However, to date, no clear understanding on the effects of social networks on business performance has emerged. This study examines the relationship between the capability of the enterprise to manage social networks and the resultant benefits of their investing in the social network. A fan page on Facebook is the selected target of study. By analyzing the effort required to manage a fan page, we measured the fan-page managing capability by its number of fans. Then, we proposed six hypotheses for empirical examination of the causal relationship between enterprises’ social network managing capability and business benefits. The study applied two-stage data collection and testing. The first stage is to build a general understanding of the relationship between the number of fans and business revenue. Based on findings of the first stage, the study tested the hypotheses on selected global firms and sought patterns of benefits generated from the fan page. This study builds deep understanding from various aspects about fan-page effects on enterprises, and proposes that firms that provide products and services with characteristics of low-product price, short-product durability, and low-customer involvement are empirically influenced by the management of their fan pages.     

Income thresholds of dissaving in Germany: empirical evidence from the recent sample survey of income and expenditure (EVS 2008)

Saving of private households monotonically increases with income. If the regression lines, which represent the ‘demand for saving’, assume negative values, saving turns into dissaving, i.e. dissolving assets or going into debt. The zeros of the demand functions for saving are called ‘dissaving thresholds’. Dissaving thresholds for Germany are determined econometrically using the Sample Survey of Income and Expenditure. Dissaving thresholds turn out to be far higher than social assistance amounts. Implications for economic, social and consumer policy in Germany are discussed.     

Ownership concentration,separation of voting rights from cash flow rights,and earnings management: an empirical study in Canada

Drawing from models of Jones (1991) and Kothari, Leone, and Wasley (2005), this study examines the relationship between Canadian corporate ownership structure and earnings management from 1995 to 1999. There is evidence of a nonmonotonic relationship. The concentration of voting and cash flow rights with the ultimate owner first increases earnings management, but as the level of ownership concentration increases, earnings management decreases. There is also a positive correlation between earnings management and voting and cash flow rights divergence. This is particularly evident when the gap between voting and cash flow rights is high.
