MATCH-UP is a series of interdisciplinary and international workshops on matching under preferences. The remit of these workshops is to explore matching problems with preferences from the perspective of algorithms and complexity discrete mathematics, combinatorial optimization, game theory mechanism design and economics, and thus a key objective is to bring together the research communities of the related areas. Another important aim is to convey the excitement of recent research and new application areas, exposing participants to new ideas, new techniques, and new problems.

List of Topics

The matching problems under consideration include, but are not limited to:

• Two-sided matchings involving agents on both sides (e.g., college admissions, medical resident allocation, job markets, and school choice)
• Two-sided matchings involving agents and objects (e.g., house allocation, course allocation, project allocation, assigning papers to reviewers, and school choice)
• One-sided matchings (e.g., roommate problems, coalition formation games, and kidney exchange)
• Multi-dimensional matchings (e.g., 3D stable matching problems)
• Matching with payments (e.g., assignment game)
• Online and stochastic matching models (e.g., Google Ads, ride sharing, Match.com)
• Other recent applications (e.g., refugee resettlement, food banks, social housing, and daycare)

Submission Guidelines

Submission deadline: February 15, 2026

Notification: April 15, 2026

We call for two types of contributions. Authors should indicate in the Keywords which format type their paper should be considered under.

Format A

• Original contribution, not previously published in (or accepted by) another conference proceedings or journal
• Not under review for a conference or journal elsewhere

Format B

• Not necessarily original work
• Could have been published already in (or accepted by) another conference proceedings or journal
• Can be under review for a conference or journal elsewhere

The Programme Committee may give priority to Format A papers in the final selection.

Submit your paper

Submissions should be at most 18 pages long (excluding bibliography), formatted for A4 paper, using 11 point font or larger with at least 1″ margins all round, and in single-column format. Submissions in EC or SAGT formats are very welcome. Any material beyond this limit should be placed in a clearly marked appendix which will be read at the discretion of the programme committee. There is no specified style file for submissions (e.g., LNCS or ACM style files are fine).

Please indicate in the Keywords whether your paper is Format A or Format B.

Proceedings

Only abstracts of accepted papers will appear in the workshop proceedings. This should allow the simultaneous or subsequent submission of contributed papers to other workshops, conferences or journals. If authors so choose, they may include a link to the full version of their paper (if published, e.g., on arXiv, REpeC, SSRN or on a personal web page) in the proceedings.

Submission of MATCH-UP Papers in TEAC

Paul Goldberg and Utku Ünver, the editors of ACM Transactions on Economics and Computation (TEAC), welcome authors whose papers were submitted to MATCH-UP for consideration at TEAC and MATCH-UP can forward your reports to TEAC. If you have a Format B paper which has appeared elsewhere, TEAC expects about 25% new material on top of the earlier version. If your paper is rejected and you wish to forward the reports, TEAC expects that you address the referee concerns in the version submitted to TEAC.

If you are planning to submit your paper to TEAC and would like us to forward the MATCH-UP reports to TEAC, please email matchup2026@gmail.com with “Paper # Review Forward Approval to TEAC” in the headline.

The deadline for submitting the revised paper to TEAC is 30 September. Please ask TEAC to request the reports and we will forward them accordingly.
