The Internet is spawning many new markets and electronic commerce is changing many market conventions. Not only are old commercial practices being adapted to the new conditions of immediacy brought forth by the global networks, but new products and services, as well as new practices, are beginning to appear. There is already ample evidence that agent-based technologies will be crucial for these - velopments. However many theoretical, technological, sociological, and legal - pects will need to be addressed before such opportunities become a significant reality. In addition to streamlining traditional transactions, agents enable new types of transactions. For example, the elusive one-to-one marketing becomes more of a - ality when consumer agents capture and share (or sell) consumer demographics. Prices and other transaction dimensions need no longer to be fixed; selling agents can dynamically tailor merchant offerings to each consumer. Economies of scale become feasible in new markets when agents negotiate on special arbitration c- tracts. Dynamic business relationships will give rise to more competitively agile organizations. It is these new opportunities combined with substantial reduction in transaction costs that will revolutionize electronic commerce.

This book constitutes the thoroughly refereed post-proceedings of the 4th International Workshop on Agent-Mediated Electronic Commerce, AMEC 2002, held in Bologna, Italy in July 2002 during the AAMAS 2002 conference. The 20 revised full papers presented together with an introductory survey by the volume editors were carefully selected and improved during two rounds of reviewing and revision. The book gives a unique overview of the state of the art of designing mechanisms and systems for agent-mediated e-commerce- The papers are organized in topical sections on electronic auctions, negotiations, and electronic markets.

This book constitutes the thoroughly refereed post-proceedings of the 6th International Workshop on Agent-Mediated Electronic Commerce, AMEC 2006, held in New York, NY, USA in July 2004 as part of AAMAS 2004. The 15 revised full papers presented were carefully selected from 39 submissions during two rounds of reviewing and revision. The papers bring together novel work from such diverse fields as Computer Science, Operations Research, Artificial Intelligence and Distributed Systems that focus on modeling, implementation and evaluation of computational trading institution and/or agent strategies over a diverse set of goods. They are organized in topical sections on mechanism design, trading agents, and tools.

This book presents 12 revised full papers on Agent-Mediated Electronic Commerce: seven papers were initially presented at the AMEC 2000 Workshop and the five others were solicited by the volume editors in order to achieve competent coverage of all relevant topics. The book is divided in topical sections on electronic negotiation models for agents, formal issues for agents operating on electronic market places, virtual trading institutions and platforms, and trading strategies for interrelated transactions.

Among the many changes brought by the Internet is the emergence of electronic commerce over the Web. E-commerce activities, such as the online exchange of information, services, and products, are opening up completely new opportunities for business, at new levels of productivity and profitability. In parallel with the emergence of e-commerce, intelligent software agents as entities capable of independent action in open, unpredictable environments have matured into a promising new technology. Quite naturally, e-commerce agents hold great promise for exploiting the Internet's full potential as an electronic marketplace. The 20 coherently written chapters in this book by leading researchers and professionals present the state of the art in agent-mediated e-commerce. Researchers, professionals, and advanced students interested in e-commerce or agent technology will find this book an indispensable source of information and reference.

Electronic Commerce, as a gamut of activities involving electronic transactions performed over a network via software that may be more or less autonomous, is an emerging reality. Strategic studies have shown that electronic commerce is a major growth industry. The book is devoted to the challenges and opportunities that electronic commerce opens for agent technology. For some time, electronic commerce has attracted the avid attention of agent-builders and agent technology researchers, and these have decisively contributed to advancing the state of the art in the field. The second-generation software agents now entering the scene hold great promise for the further advancement of electronic commerce. This book originates from a workshop on Agent-Mediated Electronic Trading held at Agents'98 in Minneapolis, Minnesota, in May 1998. The eleven carefully reviewed and revised papers present a unique survey of software agents in the context of electronic commerce.

This book constitutes the thoroughly refereed post-proceedings of the 5th International Workshop on Agent-Mediated Electronic Commerce, AMEC 2003, held in Melbourne, Australia in July 2003 as part of AAMAS 2003. The 9 revised full papers presented were carefully selected from 22 submissions during two rounds of reviewing and revision. The papers are organized in topical sections on automated negotiation, systems and mechanism design, and multi-agent markets.
