This book constitutes the refereed proceedings of the First International Symposium on Algorithmic Game Theory, SAGT 2008, held in Paderborn, Germany, in April/May 2008. The 28 revised full papes presented together with 3 invited lectures were carefully reviewed and selected from 60 submissions. The papers are organized in topical sections on routing and scheduling, markets, mechanism design, potpourri of games, solution concepts, and cost sharing.
