Final exam for Economics 283 (Game Theory), taught by Robert J. Aumann, Autumn Quarter 1975–76, Stanford University. To the best of my knowledge, this course was the first one in Game Theory offered by the Department of Economics at Stanford University. David Kreps, Paul Milgrom, and Bengt Holmstrom were among the attendees. The lecture notes for the course were published, in revised form, by the Westview Press (ISBN 978-0813375786); they are currently out of print.
