Since 1999 the ACM Special Interest Group on Electronic Commerce (SIGecom) has sponsored the leading scientific conference on advances in theory, empirics, and applications at the interface of economics and computation. The 20th ACM Conference on Economics and Computation (EC'19) will feature invited speakers, a highlight of papers from other conferences and journals, a technical program of submitted paper presentations and posters, workshops, and tutorials. EC' 19 will be held in conjunction with the ACM Federated Computing Research Conference (FCRC) in Phoenix, Arizona, from June 24 through June 28, 2019; FCRC includes the ACM Symposium on Theory of Computing (STOC) and other related conferences.

We solicit paper submissions for presentation in the technical program. The deadline for submissions is February 14th, 2019.

EC'19 has four technical tracks, detailed below.

Key dates

Forward to journal

EC'19 is piloting a new program to offer authors of accepted papers the option to have reviews forwarded to a journal of their choice. Our seven partner journals are:

Upon initial paper submission to EC'19, authors can choose at most one of these journals. Conditional upon acceptance, the authors may submit a journal version of their paper to the chosen journal, with a deadline of July 31, 2019. The cover letter should specify that the submission is part of the EC forward-to-journal process. Upon submission to the journal, the EC'19 reviews will be forwarded, along with reviewer identities, to the contact editor at that journal (listed above).

For consideration in Games and Economic Behavior, Journal of Economic Theory, Management Science, or Quantitative Marketing and Economics, authors of accepted papers must also select the one-page extended abstract option for the proceedings version, explained below. Other journals may require additional content beyond the EC'19 proceedings version; it is the responsibility of authors to ensure that the version submitted to a journal conforms with any journal-specific expectations regarding the prior proceedings version.

We emphasize that the ultimate disposition of the paper is within the editorial discretion of each journal, and in particular there is no guarantee of acceptance if the forward-to-journal option is elected. However, we do anticipate this process should result in a faster decision from the journal.

Note: Submissions forwarded to journals in this manner can instead opt for the ACM TEAC special issue dedicated to EC'19. Any such an invitation will be made prior to the July 31, 2019, deadline for forwarding to a journal.

Paper submissions

Submissions should start with a title page consisting of the title of the paper and an abstract of 1-2 paragraphs summarizing the paper's contributions. The body of the submission (after the title page) may be up to 18 pages, including bibliography. In addition, an appendix of arbitrary length may be included only for the review process (i.e., an appendix will not appear if the paper is published). This appendix will only be read at the discretion of the reviewers. The body of the submission should contain a clear presentation of the contributions of the paper, including a discussion of prior work and an outline of the key technical ideas and methods used to achieve the main claims. The submission as a whole should include all of the ideas necessary for an expert to verify fully the central claims in the paper. Submitted papers will be evaluated on significance of the contribution, originality, relation to prior research, technical quality, and exposition.

The submission should be typeset using 11-point or larger fonts, in a single-column, single-space (between lines) format with ample spacing throughout and 1-inch margins all around. Submissions deviating from these guidelines will be rejected without consideration of their merits. Alternatively, authors who choose to do so may use the style file at the following link to format their submissions.

Submissions will be accepted until February 14th, 2019 at 15:00 EST (20:00 GMT) via EasyChair:

Double blind review process. Author identity is anonymized for SPC and PC members throughout the review process. As usual, SPC and PC member identity is also anonymized before reviews are disseminated to authors. Because the review process is double blind, you must take measures to ensure that your identity is not easily revealed from the submission itself. Please include the submission number (as assigned by Easychair) in the author field of your submission, and refer to your prior work in a neutral manner (i.e., instead of saying "We showed" say "XYZ et al. showed"). To add the submission number, you need to first first submit a paper without a number, see what number was assigned to you, and then revise your submission to include this number. Furthermore, if you provide a link to data or other supplementary materials please host it in such a way that your identity is not apparent from the link. It is acceptable to submit work that has been presented in public or has appeared on ArXiV, provided the submission itself is anonymized. PC members will be allowed to declare a conflict of interest to the authors as well as to specific papers. You will still need to enter author information on Easychair when submitting the paper; this information will be accessible to the conference chairs, but not to the program committee members.

One page extended abstract option. To accommodate the publishing traditions of different fields, authors of accepted papers can ask that only a one-page abstract of the paper appear in the proceedings, along with a URL pointing to the full paper. Authors should guarantee the link to be reliable for at least two years. This option is available to accommodate subsequent publication in journals that would not consider results that have been published in preliminary form in a conference proceedings. Such papers must be submitted electronically and formatted just like papers submitted for full-text publication.

Single track review process. Any paper submission must select exactly one of the four tracks above (AI, Applied Modeling, Empirics, Theory). Senior program committee (SPC) members are assigned to tracks; each paper will be reviewed by one SPC member in the respective track and two PC members with relevant interests. The SPC and PC can be found here.

Simultaneous submission not allowed. Simultaneous submission not allowed. Simultaneous submissions of results to another conference with published proceedings is not allowed. Results previously published or presented at another archival conference prior to EC, or published at a journal prior to the submission deadline to EC, will not be considered. Simultaneous submission of results to a journal is allowed only if the author intends to publish the paper as a one-page abstract in EC. Papers that are accepted and appear as a one-page abstract can be subsequently submitted for publication in a journal but may not be submitted to any other conference that has a published proceedings.

Conflict of Interest

You will have the opportunity to declare conflicts of interest (COIs) with SPC and PC members. This must be done separately for each submission. Declaring COIs prevents the specified SPC/PC member(s) from reviewing your paper, thereby constraining the matching process and so potentially negatively impacting review quality. For this reason, CoIs should not be declared automatically based on a prior relationship (e.g., coauthor, friend, colleague in a different department at at the same institution, etc.). Instead, please declare CoIs only on those SPC/PC members who you believe will have difficulty being impartial in reviewing your paper.
