Publication of the Handbook of Group Decision and Negotiation marks a milestone in the evolution of the group decision and negotiation (GDN) eld. On this occasion, editors Colin Eden and Marc Kilgour asked me to write a brief history of the eld to provide background and context for the volume. They said that I am in a good position to do so: Actively involved in creating the GDN Section and serving as its chair; founding and leading the GDN journal, Group Decision and Negotiation as editor-in-chief, and the book series, “Advances in Group Decision and Negotiation” as editor; and serving as general chair of the GDN annual meetings. I accepted their invitation to write a brief history. In 1989 what is now the Institute for Operations Research and the Management Sciences (INFORMS) established its Section on Group Decision and Negotiation. The journal Group Decision and Negotiation was founded in 1992, published by Springer in cooperation with INFORMS and the GDN Section. In 2003, as an ext- sion of the journal, the Springer book series, “Advances in Group Decision and Negotiation” was inaugurated.

The volume offers an exploration of methods for analysis of emotion in negotiation, such as cognitive modeling, discourse analysis, all testing, subsequent multidimensional scaling, impression rating, and graph modeling for conflict resolution, reasonable and unreasonable disagreement. It covers activities, such as business negotiation, conflict solving, bargaining, task management meetings, discussions, and elaborates on different kinds of emotions. Some emotions stimulate negotiation (e.g. empathy), others -hinder it (e.g. disgust). However, all emotions open a door to uncertainty in relations and negotiation, which in turn provides an opportunity. The volume views language in negotiation not only as a vehicle for transmission of thought but also as a manifestation of emotion and the ethical.

In the global marketplace, negotiation frequently takes place across cultural boundaries, yet negotiation theory has traditionally been grounded in Western culture. This book, which provides an in-depth review of the field of negotiation theory, expands current thinking to include cross-cultural perspectives. The contents of the book reflect the diversity of negotiation—research-negotiator cognition, motivation, emotion, communication, power and disputing, intergroup relationships, third parties, justice, technology, and social dilemmas—and provides new insight into negotiation theory, questioning assumptions, expanding constructs, and identifying limits not apparent from working exclusively within one culture. The book is organized in three sections and pairs chapters on negotiation theory with chapters on culture. The first part emphasizes psychological processes—cognition, motivation, and emotion. Part II examines the negotiation process. The third part emphasizes the social context of negotiation. A final chapter synthesizes the main themes of the book to illustrate how scholars and practitioners can capitalize on the synergy between culture and negotiation research.

Praise for Handbook of Global and Multicultural Negotiation "In today's globalized world, few competencies are as essential as the ability to negotiate across cultures. In this insightful and practical book, Chris Moore and Peter Woodrow draw on their extensive global experience to help us understand the intricacies of seeking to reach intercultural agreements and show us how to get to a wise yes. I recommend it highly!" William Ury coauthor, Getting to Yes, and author, The Power of a Positive No "Rich in the experience of the authors and the lessons they share, we learn that culture is more than our clothing, rituals, and food. It is the way we arrange time, space, language, manners, and meaning. This book teaches us to understand our own culture so we are open to the other and gives us practical strategies to coordinate our cultural approaches to negotiations and reach sustainable agreements." Meg Taylor compliance advisor/ombudsman of the World Bank Group and former ambassador of Papua New Guinea to the United States of America and Mexico "In a globalized multicultural world, everyone from the president of the United States to the leaders of the Taliban, from the CEO of Mittal Steel to the steelworkers in South Africa, needs to read this book. Chris Moore and Peter Woodrow have used their global experience and invented the definitive tool for communication in the twenty-first century!" Vasu Gounden founder and executive director, ACCORD, South Africa "Filled with practical advice and informed by sound research, the Handbook of Global and Multicultural Negotiation brings into one location an extraordinary and comprehensive set of resources for navigating conflict and negotiation in our multicultural world. More important, the authors speak from decades of experience, providing the best book on the topic to date a gift to scholars and practitioners alike." John Paul Lederach Professor of International Peacebuilding, Kroc Institute, University of Notre Dame

This book reinforces the foundation of a new field of studies and research in the intersection between social sciences and specifically between political science, international relations, diplomacy, psychotherapy, and social-cognitive psychology. It seeks to promote a coherent and comprehensive approach to international negotiation from a multidisciplinary viewpoint generating a longer term of studies, researches, and networking process that both respond to changes and differences in our societies and to the unprecedented demand and opportunities for international conflict prevention and resolution. There is a need to increase cooperation, coherence, and efficiency of international negotiation. It is necessary to focus our shared attention on new ways to better formulate integrated and sustainable negotiating strategies for conflict resolution. This book acquires innovative relevance in and will impact on the new context of international challenges which do not have a one-off solution that can be settled through a single target-oriented negotiation process. The book brings together leading scholars and researchers into the field from different disciplines, diplomats, politicians, senior officials, and even a Cardinal of the Holy See to give their contributions and make proposals on how best to optimize the use of negotiation and diplomacy structures, tools, and instruments. However, unlike most studies and researches on international negotiation, this book emphasizes processes, not simply outcomes or even tools but the way in which tools are and can be used to achieve better outcomes in international reality-based negotiation.
