The First Annual ACM SIGecom Winter Meeting

The winter meeting has come to an end. Thank you to everyone who joined us!

The First SIGecom Winter Meeting will take place February 25, 2021.

The SIGecom Winter Meeting brings together researchers from economics and computation and adjacent communities. It takes the form of a workshop focusing on a topic of interest in economics and computation, with the goal of building community and strengthening research connections.

The first meeting will be held virtually on February 25, 2021, 11am - 5pm US Eastern time (ET). The inaugural topic will be auctions with correlated and interdependent valuations, centered around the contributions of this year's Nobel prize winners Robert Wilson and Paul Milgrom. The meeting will begin with a set of tutorials covering classical material, followed by invited talks that showcase the state-of-the-art on these and related topics. The workshop will feature ample opportunity to socialize and discuss the material with colleagues.


The event is free of charge, but registration is required for access to the virtual space. Register Here!

The workshop will take place on the platform. This platform provides a 2d layout in which participants can navigate an avatar using the arrow keys. When a group of avatars are in close proximity, a video conference is started. Tables and chairs provide private video conferencing space. Talks will take place in Zoom webinars that can be accessed from within the virtual space. Please note that you will need to register to obtain the login credentials.

Social Games

The workshop will feature an auction bidding game and a social network game for registered participants. Submit your entries by visiting the game booths in the virtual space!

A full description of the game rules can be found at the links above. Personalized signals for the auction game will be emailed to registered participants just before the workshop.

The games are now closed! For the auction games, the secret value was $81.77. Here is a short note about optimal bidding strategies when signals aren't shared. And here is the distribution of bids (removing outliers). We received 53 bids for each auction, and it looks like there was a lot of information-sharing!

Here are the game winners:

First-Price Auction Game: Mehmet S. Ismail (bid: $81.18)

Second-Price Auction Game: Nikita Kalinin (bid: $82.00)

Social Network Game: Linda Cai (chain length: 5)

Each winner selected a charity to receive a donation. The chosen charities were the Baltic Seal Friends Fund, St. Jude Children's Research Hospital, and Scholarship America. Thank you to everyone who participated!


All times listed in US Eastern Time Zone (ET). All talks will take place in the auditorium unless otherwise noted.
