Welcome to the 2024 volume of the Group Decision & Negotiation journal. After the first post-COVID 19 year of 2022, 2023 saw an increased amount of in-person academic collaboration and information sharing. The GDN 2023 conference in Tokyo was a great success with many scientific progress being reported by GDN researchers from around the world. Being the first in-person conference since 2019, the organizing hosts from the University of Tokyo provided all participants with an exceptional experience. As usual, we are working with the authors to publish some of the best conference papers in the journal.

2023 was another successful year for the GDN journal. We received a total of 262 submissions which is an increase of 6% compared to the previous year. The six issues of the journal published a total of 53 papers which represents an 18% increase over the prior year. The average number of days from submission to first decision has been steadily decreasing: it dropped from 92 days in 2019 to 32 days in 2023. This is an amazing turnaround time which everyone on the editorial board should feel proud of! The journal’s h5-index improved further to 27 while the journal’s impact factor increased to 3.0 (2022). Finally, the number of full-text article downloads keeps breaking records as well: after the first three quarters of 2023 the journal recorded 144,287 downloads, already a 12% increase compared to the whole 2022 calendar year.

Together, these numbers show that the journal continues to be the prime outlet for research on group decision and negotiation. Our aim continues to be soliciting strong submissions that receive a swift decision to keep improving the journal’s metrics in 2024. We welcome proposals for special issues and submissions on innovative topics. Review papers are also encouraged that can serve as a focal point for specific GDN research areas.

1 The Editorial Board & Reviewers

The Group Decision & Negotiation journal is fortunate to have a committed editorial board and group of reviewers. They work tirelessly to assess the contributions and quality of each submission that is entered into the review process. They assist the authors through constructive criticism to ensure that each published paper makes a significant contribution to the Group Decision & Negotiation body of knowledge.

We are extremely grateful to our current editorial board members, several of whom have carried a heavy load. We truly appreciate their hard work and dedication during the past year. For 2024, there are a few changes to the composition of the board. Several board members indicated their desire to retire. We thank the following colleagues for their many years of service to our community:

  • Deepinder Bajwa, Western Washington University, USA

  • Mario Fedrizzi, University of Trento, Italy

  • Keith Hipel, University of Waterloo, Canada

  • Fuad Aleskerov, HSE Moscow, Russia

  • Hannu Nurmi, University of Turku, Finland

  • Gerelt Tserenjigmid, University of California, Santa Cruz

We are also grateful to welcome several new board members who will strengthen the board’s coverage of the various GDN research areas and also strengthen the board’s diversity in terms of global regions, gender, career stage, and ethnicity. Our newest board members are:

  • Eduarda Asfora Frej, Federal University of Pernambuco, Brazil

  • Zhen Zhang, Dalian University of Technology, China

We would be amiss not to recognize the fantastic support from the editorial team at Springer: Matthew Amboy, Ashlea Highfill, Chitra Vijayaraghavan, Balamurugan Rajendran, and Prathap Panneerselvam. We are grateful for their professionalism and responsiveness. It is a pleasure to work with each and every one of them.
