You are cordially invited to submit papers to the 21st International Conference on Group Decision and Negotiation, GDN 2021, 6-10 June 2021, Ryerson University, Toronto, Canada.

The field of Group Decision and Negotiation focuses on decision processes with at least two participants and a common goal. Such processes are complex and self-organising and constitute multi-participant, multi-criteria, ill-structured, dynamic, creative, and often evolutionary problems. Major approaches include:

  1. Information systems, in particular negotiation support systems (NSSs) and group decision support systems (GDSs)
  2. Cognitive and behavioural sciences as applied to group decision and negotiation
  3. Conflict analysis and resolution
  4. Applied game theory, experiment and social choice
  5. Artificial intelligence
  6. Management science as it relates to group decision making and negotiation. Many research initiatives combine two or more of these approaches.

Group Decision and Negotiation can be performed in an intra-organisational as well as an inter-organisational context. Both consist of complex processes, including preference elicitation, proposals and counter-proposals, preference adjustment, and choice. Communication and decision making are the two key process steps in Group Decision and Negotiation and thus require sophisticated support in many ways.

Application areas of Group Decision and Negotiation include intra-organisational and inter-organisational coordination (as in operations management and integrated design, production, finance, marketing and distribution functions, such as coordination of all phases of the life cycle of a product), computer-supported collaborative work and meetings, electronic negotiations including negotiating agents and negotiation support systems, labour-management negotiations, inter-organisational, intercultural negotiations, environmental negotiations, and many others.

Themes and areas of interest include but are not limited to the following:

Methodological & Theoretical Foundations

Behavioral Aspects

  • Comparisons of auction and negotiation mechanisms
  • Creativity in GDN
  • Characteristics of cross-cultural and intracultural negotiation
  • Emotions in GDN
  • Gender and negotiation
  • Facilitation

  • Interaction of human and software agents
  • Experimental studies in GDN
  • Learning and teaching
  • Micro-Processes


  • Business
  • Policy
  • Diplomacy and international relationships
  • Education
  • Water and natural resources
  • Sustainability
  • Software engineering

Papers can be submitted as full papers to be published either in Conference proceedings by Springer in the Book series of LNBIP  (Lecture Notes in Business Information Processing) or as abstracts/extended abstracts/full papers to be published in Local Proceedings by Loughborough University.

In the Local Proceedings the authors will keep the copyright. After the reviewing process, the authors could choose to replace their full paper in the Local Proceedings for abstract only. However, to be considered for the Conference Awards evaluation process, those papers should be available as full papers in the Local Proceedings, which will be on a stick that is given only to conference participants, at the beginning of the conference.

The topics are organized in conference streams that can be found on the website  (click here). Research in Group Decision and Negotiation has continued to expand, and many new research directions have been proposed. At GDN conferences, we encourage researchers to present research in Group Decision and Negotiation even if (in fact, especially if) it does not fit into any of the above areas. We particularly invite Bachelor and Master students to submit their work to the dedicated Student Stream.
