This paper introduces a model for analyzing marketplaces, such as eBay, which rely on binary reputation mechanisms for quality signaling and quality control. In our model sellers keep their actual quality private and choose what quality to advertise. The reputation mechanism is primarily used to induce sellers to advertise truthfully. Buyers base their ratings on the difference between expected and actual quality. Furthermore, raters are lenient and do not post negative ratings unless transactions end up exceptionally bad. It is shown that, in such a setting, the fairness of the market outcome is determined by the relationship between rating leniency and corresponding strictness when assessing a seller's feedback profile. If buyers judge sellers too strictly (relative to how leniently they rate) then, at steady state, sellers will be forced to understate their true quality. On the other hand, if buyers judge too leniently then sellers can get away with consistently overstating their true quality. An optimal judgment rule, which results in outcomes where, at steady state, buyers accurately predict the true quality of sellers, is theoretically possible to derive for all leniency levels. Furthermore, if buyers judge sellers using that rule, then the more lenient buyers are when rating sellers, the more likely it is that sellers will find it optimal to settle down to steady-state quality levels, as opposed to oscillating between good quality and bad quality. However, it is argued that this optimal rule depends on several parameters, which are difficult to estimate from the information that eBay currently makes available to its members. It is therefore questionable to what extent unsophisticated buyers are currently using eBay feedback information in an optimal way.

Information Systems Development (ISD) progresses rapidly, continually creating new challenges for the professionals involved. New concepts, approaches and techniques of systems development emerge constantly in this field. Progress in ISD comes from research as well as from practice. This conference will discuss issues pertaining to information systems development (ISD) in the inter-networked digital economy. Participants will include researchers, both experienced and novice, from industry and academia, as well as students and practitioners. Themes will include methods and approaches for ISD; ISD education; philosophical, ethical, and sociological aspects of ISD; as well as specialized tracks such as: distributed software development, ISD and knowledge management, ISD and electronic business / electronic government, ISD in public sector organizations, IOS.

Ambient Intelligence Perspectives contains selected papers from the first international Ambient Intelligence Forum AmIF 2008 in Hradec Kraacute;loveacute;, Czech Republic. The forum is intended as the beginning of a series of rather broadly oriented discussion opportunities for discussing interdisciplinary, if not transdisciplinary aspects of rapidly evolving areas of Ambient Intelligence. Its aims were to review and discuss recent advances and promising research trends in AmI technology, intelligent environments, methods, middleware development, as well as applications in areas such as healthcare, product lifecycle and transport services. The intention to provide an opportunity of a very broad interaction among a wide rank of A01s coming from different surroundings means a great enrichment to all participants and gives ground to the success of the conference. Finally it led towards an interesting choice of three invited and twenty-five contributed papers, which are published in this book. All papers were carefully reviewed by the international program committee. Participants from twelve countries contributed to the scientific program and established a fruitful discussion atmosphere.

In recent years game theory has had a substantial impact on computer science, especially on Internet- and e-commerce-related issues. Algorithmic Game Theory, first published in 2007, develops the central ideas and results of this exciting area in a clear and succinct manner. More than 40 of the top researchers in this field have written chapters that go from the foundations to the state of the art. Basic chapters on algorithmic methods for equilibria, mechanism design and combinatorial auctions are followed by chapters on important game theory applications such as incentives and pricing, cost sharing, information markets and cryptography and security. This definitive work will set the tone of research for the next few years and beyond. Students, researchers, and practitioners alike need to learn more about these fascinating theoretical developments and their widespread practical application.

This professional book discusses privacy as multi-dimensional, and then pulls forward the economics of privacy in the first few chapters. This book also includes identity-based signatures, spyware, and placing biometric security in an economically broken system, which results in a broken biometric system. The last chapters include systematic problems with practical individual strategies for preventing identity theft for any reader of any economic status. While a plethora of books on identity theft exists, this book combines both technical and economic aspects, presented from the perspective of the identified individual.

The World Wide Web has become part of our everyday life and information retrievalanddataminingontheWebisnowofenormouspracticalinterest.Some of the algorithms supporting these activities are based substantially on viewing the Web as a graph, induced in various ways by links among pages, links among hosts, or other similar networks. Theaimofthe2004WorkshoponAlgorithmsandModelsfortheWeb-Graph was to further the understanding of these Web-induced graphs, and stimulate the development of high-performance algorithms and applications that use the graphstructureoftheWeb.Theworkshopwasmeantbothtofosteranexchange of ideas among the diverse set of researchers already involved in this topic, and to act as an introduction for the larger community to the state of the art in this area.
