The Prize in Game Theory and Computer Science of the Game Theory Society in Honour of Ehud Kalai was established in 2008 by a donation from Yoav Shoham in recognition of Ehud Kalai’s role in promoting the connection of the two research areas.

Eligibility Rules for Awards until 2016

The Prize is awarded to the person (or persons) who have published the best paper at the interface of game theory and computer science in the last decade. Preference will be given to candidates of age 45 or less at the time of the award, but this is not an absolute constraint. The amount of the Prize is USD 2,500 plus travel expenses of up to USD 2,500 to attend the Congress.

Amended Eligibility Rules for Awards after 2016

The GTS officers approved in January 2016 new eligibility rules. As recommended by the 2016 Prize Committee (Preston McAfee, David Parkes, Eva Tardos, and Bernhard von Stengel), they follow the eligibility rules of the Gödel Prize (change highlighted in italics):

The Prize will be awarded to the person (or persons) who have published the best paper at the interface of game theory and computer science.
Any research paper is eligible that was published in a recognized refereed journal before nomination, but the main results were not published (either in preliminary form in conference proceedings or on a preprint server, or in final form) 14 or more years before the year of the award. This extended period is in recognition of the fact that the value of fundamental work cannot always be immediately assessed.
Preference will be given to candidates of age 45 or less at the time of the award, but this is not an absolute constraint. The amount of the Prize will be USD 2,500 plus travel expenses of up to USD 2,500 to attend the Congress.
