21st Max Planck Summer School:
Advanced Course on the Foundations of Computer Science (ADFOCS 2020)

August 24 – 28, 2020

Saarbruecken, Germany



ADFOCS is an international summer school that has been held annually for the last twenty years at the Max Planck Institute for Informatics (MPII) in Saarbruecken, Germany. It is organized as part of the activities of the MPII, in particular the International Max Planck Research School (IMPRS), MPII’s graduate program. The purpose of this summer school is to introduce young researchers to topics which are the focus of current research in theoretical computer science. We bring together leading researchers in the field and international participants at the graduate level and above. This year’s focus is on:

*** Market Design and Computational Fair Division ***
Our invited speakers give five 60-min lectures with subsequent exercise and discussion sessions. These sessions will take place daily from 14:30 to 18:30 UTC+2 (CEST) in the week of August 24-28. On some days there will be a social event after the regular schedule. This year’s speakers are:

* Nicole Immorlica, Microsoft Research Lab, New York City, USA
* Jugal Garg and Ruta Mehta, University of Illinois at Urbana-Champaign, USA
This year registration is free as the event takes place virtually. Nevertheless, registration is MANDATORY and can be done through the website (at the latest August 10)

Guest post by Tilman Borgers (JET Lead Editor), Marciano Siniscalchi (JET Editor), and Jason Hartline (JET Associate Editor):

The Journal of Economic Theory (JET) would like to encourage submissions from computer scientists. JET is a leading journal of the economic theory community, and has a broader readership among economists and covers a broader range of topics than other theory journals. JET is also the first field journal of the economic theory community, having been founded more than 50 years ago. Many publications in JET in those 50 years have changed not just the direction of economic theory, but also the direction of economics overall.

The convergence of research interests of computer scientists and economic theorists has been a remarkable development, and JET would like to do more to help facilitate the exchange of ideas across fields. Therefore, we compile here some suggestions for computer scientists who are interested in submitting their work to JET.

The basic standard for a publication in JET is that the paper should be original, make a substantial contribution, and be of interest to a broad group of readers, and this group should include economic theorists. Of course, editors make subjective, and fallible, judgments when assessing whether a paper meets these criteria. Typically, the substantive contribution is a contribution to economic theory, i.e. to our understanding of models of markets, strategic games, mechanisms, etc. Papers may be computer-science centric in its contributions, but then these contributions should be on a topic of interest to economists. For example, new algorithmic results related to game theory or mechanism design may be of interest to JET, if it is the editors’ judgment that these algorithms will be of interest to economists. On the other hand, results on more applied computational problems, such as faster algorithms for winner determination in auctions, or for clearing prediction markets, may be out of scope for JET.

In terms of style, successful JET submissions include an introduction that is accessible to a broad theory audience, and that explains the motivation for the work, overviews the main results, and explains some key intuitions. The introduction, or a separate literature review section, should precisely situate the work relative to the most closely related research. The main body of the paper should explain the model rigorously, and state the results precisely. Proofs which are not very long, and which provide insight, are typically included in the main body of the paper, whereas other proofs are moved to an appendix. It is often useful to paraphrase results in words after stating them formally, and to give explanations of intuitions as well as explanations of proof structures. We encourage authors to make their work as simple as is possible without losing the main message.

There is no length limit per se, but published papers have rarely more than 40 pages, including appendix and references, in print. We value conciseness, and focus on a main theme throughout the paper. Minor results can be left out. On the other hand, we do provide authors with the space needed to be precise and clear.

One general recommendation for computer science authors in preparing manuscripts for economics journals is to have an economist colleague look over the paper before submitting. This is a good way to identify inaccurate assumptions about readers’ knowledge, or omitted relationships to the prior literature in economics. Such advice can also help better motivate the results of the paper from an economic perspective.

To be publishable, if an earlier version of a paper was published as an extended abstract in conference proceedings, then the journal version must make additional contributions beyond the conference version. This additional contribution may include important conceptual aspects of economic interest that were omitted from the original extended abstract, proofs that were omitted from the extended abstract, and additional results that did not appear in the extended abstract. Authors should explain the differences between the conference version and the journal version in a cover letter. Papers that have previously appeared as one or two page abstracts in a conference volume do not need to distinguish themselves. Mentioning these appearances in a cover letter would useful, however.

Virtual EC 2020

EC 2020 will be held virtually with events from June 15 to July 22 (details of virtual format).  Participation by members of related fields is strongly encouraged.  

Since 1999 the ACM Special Interest Group on Economics and Computation (SIGecom) has sponsored the leading scientific conference on advances in theory, empirics, and applications at the interface of economics and computation. The 21st ACM Conference on Economics and Computation (Virtual EC 2020) 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.  

Registration is mandatory (register here) but complimentary with SIGecom membership of $10 ($5 for students).  Details on joining EC events will be emailed to registered participants.

An overview of the schedule:

June 15 – 19: Mentoring Workshop and Live Tutorial Pre-recording Sessions.
June 22 – July 3: Live EC Paper Pre-recording Plenary Sessions.
July 13: Tutorial Watch Parties, Business Meeting, and Poster Session

From the Virtual Transition Team for EC 2020: Due to concerns regarding the novel coronavirus COVID-19, the 2020 ACM Conference on Economics and Computation (EC 2020) will be held virtually.  This change of format offers exciting new opportunities. This guide can also be found on the EC 2020 webpage.


June 15 – 19: Mentoring Workshop and Live Tutorial Pre-recording Sessions.
June 22 – July 3: Live EC Paper Pre-recording Plenary Sessions.
July 13: Tutorial Watch Parties, Business Meeting and Poster Session
July 14 – 16: EC Conference (Paper Watch Parties, Paper Poster Sessions, and Plenaries).
July 17 – 22: Workshops.


The planning committee has been hard at work revisioning EC 2020 as a virtual event.  The event aims to emphasize opportunities afforded by the virtual format with activities that are intractable in the physical format, but not to recreate aspects of the physical conference experience that are difficult virtually.  Some aspects of the event will look similar to a physical conference, while some will be quite different.  The desiderata for the selected format are:

  • Maximize exposure for EC papers.
  • Maximize interaction between community members.
  • Allow broad global accessibility.

The organizational team studied the results of many virtual conferences that have already taken place (AAMAS, ASPLOS, EuroSys, ICCP, ICLR, WAGON, among others, as well as the ACM guidelines).  Some general rules of thumb are (a) prerecording talks, (b) emphasizing posters, (c) expecting about four hours a day of participation, (d) prime time is 11am-3pm ET.  

The planning committee adopted a strategy that allows the minimal commitment level for authors and attendees of presenting and viewing 18 minute talks and attending activities only during the main EC week of July 13-17.  However, official EC events will run June 15 to July 24 and the planning committee highly encourages members of the community to enjoy a more relaxed pace where all programming is plenary.


Registration will be mandatory but complementary with ACM SIGecom membership ($10 Professional / $5 Student) which can easily be completed online.  Registration will open on June 1.

Mentoring Workshop and Live Tutorial Pre-recording Sessions

June 15-19: To give junior researchers plenty of time to prepare for the EC conference, the mentoring workshops and tutorial live pre-recording sessions will be held the week of June 15.  In addition to the usual activities, junior students will be paired with senior students who will share their EC itinerary and be available for discussions of papers and events in online chat throughout the duration of the EC events.  There will be three tutorials, each broken into four 45 minute segments and recorded over several days and with live audiences of EC participants.  Students will be able to work together on exercises in between sessions.

Live Paper Pre-recording Plenary Sessions

June 22 – July 3:  EC papers will keep the usual 18-minute format.  The planning committee highly encourages authors to choose to pre-record their EC talks in live pre-recording sessions.  Each session comprises three papers and is followed by a virtual coffee break for discussion between the speakers, coauthors, and attendees.  Speakers and attendees are recommended to schedule for 2 hours.  These sessions are all plenary and will be scheduled for synergies in topic and preferred timing of the speakers.  These sessions begin at regular times:

  • US Eastern/China 9:00, 13:00, 17:00, 21:00, 1:00, 5:00.
  • US Central/Israel  8:00, 12:00, 16:00, 20:00, 24:00, 4:00.
  • US Mountain/Europe 7:00, 11:00, 15:00, 19:00, 23:00, 3:00.
  • US Pacific/London  6:00, 10:00, 14:00, 18:00, 22:00, 2:00.

We expect about three sessions a day over the ten weekdays between June 22 and July 3.  (Pre-recording sessions are optional but highly encouraged for authors of EC papers.)

EC Conference

July 13-16: July 13 is tutorial day.  It will include the EC business meeting and a contributed poster session for breaking results and results from other venues.  The main conference runs July 14-July 16 with programming from 9am-5pm Eastern.  This programming includes pre-recorded talk watch parties, poster discussion sessions for the papers, live plenary talks, and live highlights beyond EC.  The paper and poster discussion sessions will run in two-hour blocks as follows:

Hour 1: 3-5 parallel tracks of watch parties (3 papers each), with realtime chat with the authors.

Hour 2: plenary 1-minute lightning talks for all papers, breakout room for discussion for each paper with poster (a poster is 1-4 slides in PDF). (The lightning talks and poster discussion rooms are optional but highly encouraged for authors of the session’s papers.)

As these watch parties will be in parallel sessions and some may be at times that are hard for some members of the community to attend, the planning committee highly encourages participation in the live pre-recording sessions (June 22-July 3) and all talks will be available for individual viewing in advance of the conference. 

EC Workshops

July 17-22: Three workshops will take place on the Friday of EC and the following week.  Details for these events are still being worked out by the organizers.

Best Presentation by Student or Postdoctoral Research Award.

The Best Presentation by a Student or Postdoctoral Researcher Award is designed to encourage and acknowledge excellence in oral presentations by students and recent graduates. In addition to an honorarium, this year’s winner will be invited to present in a special session at WINE 2020 with expenses covered by SIGecom. To be considered for the award, the presenter must participate in a live pre-recording session.  This year will feature several “fun” categories for video presentations. Audience nominations are requested for creative and fun videos in the categories of: Best Video, Best Cameo by a Child or Pet, Best Special Effects, Best Soundtrack, or Best [Insert Your Nomination Here]. Submit nominations here.

Virtual Transition Team

Virtual aspects of the conference are being coordinated by a Virtual Transition Team appointed by the SIGecom Executive Committee, that in addition to the Executive Committee and the EC 2020 organizing committee includes the following officers:

  • Virtual General Chair: Jason Hartline
  • Virtual Local Chair: Yannai Gonczarowski
  • Virtual Global Outreach Chairs: Rediet Abebe and Eric Sodomka

The team is looking forward to interacting with everyone in the community at an outstanding conference!

The First Symposium on Foundations of Responsible Computing (FORC 2020) is a forum for mathematical research in computation and society.  The Symposium aims to catalyze the formation of a community supportive of the application of theoretical computer science, statistics, economics and other relevant analytical fields to problems of pressing and anticipated societal concern.

Lead by program chairs Cynthia Dwork, Omer Reingold, and Aaron Roth; the virtual symposium is on June 1st and 2nd, 2020.  The program consists of keynote talks by Adrian Weller, Rakesh Vohra, Patricia Williams, and Jon Kleinberg; and 21 contributed papers.  The conference is free but registration is required.  The full program is available on the conference webpage.

As many of you have probably anticipated, due to concerns regarding the novel coronavirus COVID-19, the 2020 ACM Conference on Economics and Computation (EC 2020) will be held virtually.

This change of format will of course present us with difficult challenges, but we believe it will offer exciting new opportunities as well.  (And not to worry, your opportunity to attend EC in Budapest is just deferred to 2021.)

The SIGecom Executive Committee has appointed and will serve on a Virtual Transition Team that additionally includes the following new conference officers:

This team is working with the EC 2020 organizing committee and EC 2020 PC chairs to put together a plan that leverages the opportunities of the virtual format to the fullest extent. Though these plans are still in the works, we have identified the following “minimal commitment” for authors of accepted papers to the main EC conference: at least one author will need to

  • register for the conference;
  • be available virtually on the conference dates (July 14-16);
  • provide a camera-ready paper or abstract by the camera-ready deadline;
  • provide a pre-recorded talk presenting the paper two weeks in advance (by June 28).

We are optimistic that, while a virtual EC may lack some of the positive features of a classical conference, the format will also provide opportunities that improve on the classical experience.  As with any conference there will be opportunities to participate beyond the “minimal commitment.”  We hope that speakers and participants will join in other activities, which may include preview sessions for talks before the conference proper, watch parties for speakers and attendees, and mechanisms for reaching a wider audience with the technical program. With many academic interactions moving virtual, the barriers to collaboration with distant colleagues have lowered, and we hope that EC 2020 will kindle and rekindle global collaborations.

Further details about these activities as well as the minimal requirements will be circulated by June 1.

Tutorial speakers and workshop organizers will receive separate emails from the Tutorial and Workshop Chairs about plans for moving these events online.

Call for Papers: the 2nd Workshop on Behavioral Economics and Computation
We solicit research contributions and participants for the 2nd Workshop on Behavioral Economics and Computation, to be held in conjunction with the Twenty-First ACM Conference on Economics and Computation (ACM EC ’20).
Based on the successful workshop last year, we aim to bring together again researchers and practitioners from diverse subareas of EC, who are interested in the intersection of human economic behavior and computation, to share new results and to discuss future directions for behavioral research related to economics and computation. It will be a full-day workshop, and will feature invited speakers, contributed paper presentations and a panel discussion.
The gap between rationality-based analysis that assumes utility-maximizing agents and actual human behavior in the real world has been well recognized in economics, psychology and other social sciences. In recent years, there has been growing interest in conducting behavioral research across many of the sub-areas related to economics and computation to address this gap. In one direction, some of these studies leverage insights on human decision making from the behavioral economics and psychology literature to study economic and computational systems with human users. In the other direction, computational tools are used to study and gain insights on human behavior and a data-driven approach is used to learn behavior models from user-generated data.

The 2nd Behavioral EC workshop aims to provide a venue for researchers and practitioners from diverse fields, including but not limited to computer science, economics, psychology and sociology, to exchange ideas related to behavioral research in economics and computation. In addition to sharing new results, we hope the workshop will foster a lively discussion of future directions and methodologies for behavioral research related to economics and computation as well as fruitful cross-pollination of behavioral economics, cognitive psychology and computer science.

We welcome studies at the intersection of economic behavior and computation from a rich set of theoretical, experimental and empirical perspectives. The topics of interest for the workshop are behavioral research in all settings covered by EC, including but not limited to:
  • Behavioral mechanism design and applied mechanism design
  • Boundedly-rational models of economic decision making
  • Empirical studies of human economic behavior
  • Model evaluation and selection based on behavioral data
  • Data-driven modelling
  • Online prediction markets, online experiments, and crowdsourcing platforms
  • Hybrid human-machine systems
  • Models and experiments about social considerations (e.g. fairness and trust) in decision making
  • Methods for behavioral EC: information aggregation, probability elicitation, quality control
Submission Instructions
Submission deadline: May 18, 2020, 11:59pm PDT.
Notification: June 11, 2020
All submissions will be peer reviewed. We will give priority to new (unpublished) research papers but will also consider ongoing research and recently published papers that may be of interest to the workshop audience. For submissions of published papers, authors must clearly state the venue of publication. Position papers and panel discussion proposals are also welcome. Papers will be reviewed for relevance, significance, originality, research contribution, and likelihood to catalyze discussion.

Submissions can be in any format and any length. We recommend the EC submission format.
The workshop will not have archival proceedings but will post accepted papers on the workshop website. At least one author of each accepted paper will be expected to attend and present their findings at the workshop.

Submissions should be uploaded to Easychair no later than May 18th, 2020, 11:59pm PDT.
