The New Directions in Social Choice workshop, co-located with EC'24 in New Haven, aims to bring together researchers working on topics related to voting and social choice. With a focus on recent developments, new application domains, and new analysis frameworks, the workshop will provide a platform for discussing the latest breakthroughs and charting directions for future work in the field.
Social choice theory has been studying collective decision making since the 1950s. Recent progress has deepened our understanding along several axes of innovation:
Social choice theory has been applied to new application domains, and theoretical progress (e.g., voting in combinatorial domains) has fueled new applications (e.g., participatory budgeting).
New analysis frameworks have given the field new perspectives on well-known questions. Examples include distortion in metric spaces, best-of-both-world guarantees, and forms of beyond-worst-case analysis.
Social choice theory has also made progress in accounting for hard-to-model facets of decision-making, such as deliberation and learning systems.
The purpose of this workshop is to highlight recent breakthroughs in these directions, chart directions for future work, and bring together the social choice community at EC.
This half-day workshop will take place on Monday, July 8 at the EC conference. The workshop will feature contributed and invited talks, an open-problem session, and a poster session.
We are soliciting paper contributions on the topics of this workshop. We encourage authors to submit papers using the EC style files, but other formats are also acceptable. Submissions will be lightly reviewed, and we prefer focussed and short versions of papers. We will accept papers both as poster and as oral presentations.
This is a non-archival workshop and we welcome papers that have been recently published or that are currently under review elsewhere. Papers accepted at EC 2024 should not be submitted. Submissions need not be anonymized.
Papers can be submitted via CMT: https://cmt3.research.microsoft.com/SocialChoiceEC2024/Submission/Index
Abstract deadline: Wednesday, 22 May 2024, 23:59 AoE
Full paper deadline: Thursday, 23 May 2024, 23:59 AoE
Notification: Friday, 31 May 2024
Workshop: Monday, 8 July 2024 from 08:00 AM
