We are excited to announce the Call for Papers for The 2nd International Workshop on Mechanism Design in Social Networks (MNet-2025), a pivotal event that brings together leading researchers from multi-agent systems, algorithmic game theory, and the social, economic, and organizational sciences. MNet-2025 2025 is part of the IJCAI 25 conference taking place in Montreal, Canada, from August 16 to August 22, 2025.

The aim of the workshop is to provide an internationally respected forum for scientific research tackling the fundamental challenges of mechanism design in social networks. As a representative interface integrating economics, game theory and artificial intelligence, mechanism design takes an engineering approach to solve a wide range of problems where there are interactions among individuals, markets and institutions. Research on mechanism design has brought many novel solutions to the practice such as spectrum allocations, kidney exchanges, student-school matching systems, and digital/sharing economy platforms. However, the traditional settings/solutions do not specifically consider the complex interactions of individuals under the social networks. Therefore, since 2017, we have seen many studies focused on the mechanism design problems under social networks, including auctions, matching, cooperative games and many other games under social networks. Almost all the traditional games/mechanisms can be revisited under the network setting and there are also many challenging open questions worth further investigations. Hence, we hope this workshop could stimulate the studies in this trend, and offer a platform to related researchers and practitioners to swiftly exchange mature and immature ideas.

Research contributions related to algorithmic game theory, mechanism design, and social choice that are considering social networks are welcome for the workshop. Topics and research questions to be explored include, but not limited to, the following:

• Auctions on Networks
• Coalition Formation under Networks
• Reward/Cost Sharing under Networks
• Invitation Incentive Design
• Crowdsourcing and Crowdsensing
• Information Elicitation and Data Acquisition
• Social Choice on Networks
• Matching Markets on Networks
• Network Games and Liquid Democracy
• Distributed Mechanisms on Networks
• Security, Privacy, and Trust
• Economic Aspects of Distributed Algorithms
• Economics, Monetization, and Online Markets
• Federated Learning and Social Learning
• Social Network Analysis and Graph Algorithms
• Network Formation Games
• Social Influence and Learning on Social Networks
• Influence Maximization
• Economic Networks and Market Analysis

Workshop Format. The workshop will feature invited speaker/s, paper presentations, and panel discussions. It is a one-day workshop taking place during the workshop days of IJCAI 2025.

Target Audience. The workshop will be of interest to researchers (including young masters and PhDs) engaged in modeling and analyzing economic mechanisms powered by social networks, and those interested in putting mechanism design theory to work. MNet-2025 intends to be a place where researchers can exchange and publish mature ideas and can also quickly get useful feedback about immature results (and publish short abstracts).

  The Submission System

  space

• All contributions will be peer-reviewed by at least two independent PC members. The evaluation criteria of contributions will be based on originality, quality, clarity, and its relevance to the workshop.
• All papers should be original and multiple submission of the same paper to more than one IJCAI workshop is forbidden.
• At least one author of each accepted paper must travel to the IJCAI workshop to present the paper in person.

Publication

Research contributions on algorithmic game theory, mechanism design, auctions, social choice, and other topics related to social networks are welcome for the proposed workshop. Topics and research questions to be explored include, but not limited to, the following: Communications in Computer and Information Science (CCIS) abstracted/indexed in DBLP, Google Scholar, EI-Compendex, Mathematical Reviews, SCImago, Scopus. Each accepted paper can choose to publish a full paper, a short paper or not publish at all. The goal is that if you have some new results that you want to get published quickly, the post-proceedings is a good venue. Also if you just want to get a promotion of your results but still want to send the paper to another venue, then a short paper or not publish at all is also a good choice.
