This book constitutes the thoroughly refereed post-proceedings of the 7th International Workshop on Agent-Mediated Electronic Commerce, AMEC VII 2005, held in Utrecht, Netherlands in July 2005, as part of AAMAS 2005, and the third Workshop on Trading Agent Design and Analysis, TADA 2005, held in Edinburgh, UK in August 2005, in the course of the IJCAI 2005 conference meetings. The 7 revised full AMEC 2005 papers presented were carefully selected and address a mix of both theoretical and practical issues, looking at behavioral and organizational dimensions of agent-mediated electronic commerce as well as at complex computational, information and system-level challenges. An extended version of an article originally presented at AMEC 2004 has also been included. The second part of the book comprises 8 revised full papers of TADA 2005 that focus on trading agent technologies and mechanism design, including discussions of agent architectures and decision-making algorithms along with theoretical analyses and empirical evaluations of agent strategies in different trading contexts.
