Why do we need a handbook on Information Technology (IT) and Finance? At first, because both IT as well as finance, are some of the most prominent driving forces of our contemporary world. Secondly, because both areas develop with a terrific speed causing an urgent need of up to date information on recent dev- opments. Thirdly, because serious applications of IT in Finance require specialists with a professional training and professional knowledge in both areas. Over the last decades the world has seen many changes in politics, economics, science and legislation. The driving forces behind many of these developments are of a technological nature. One of the key technologies with this respect is Infor- tion Technology. IT is the most prominent technology revolutionizing the ind- trial development, from products and processes to services, as well as finance, which is itself one of the central pillars of modern economics. The explosive - velopment of the Internet emphasizes the importance of IT, since it is today’s key factor driving global access and availability of information and allows the division of labour on an international scale, the globalization. The profound transformation of finance and the financial industry over the last twenty years was driven by technological developments – e. g.

This book contains a selection of papers presented at the Dagstuhl Seminar “Negotiation and Market Engineering” held for one week in November 2006, in Schloss Dagstuhl, Germany. The papers were submitted for publication in this book and reviewed after the seminar. The seminar was a meeting point for participants from academia and industry who arrived from four continents to discuss research on negotiations, auctions, and markets as well as their application. Analyzing, designing, and introducing such complex systems as negotiations, auctions, and markets inevitably requires an interdisciplinary approach because of their psychological, social, and cultural character; economic, legal, and political aspects; quantitative and qualitative considerations; and strategic, tactical, and managerial perspectives. Thus the organizers of the seminar paid special attention to having a mix of researchers with diverse backgrounds from various disciplines – the most common disciplines represented at the seminar were computer science, information systems, economics, business administration, and mathematics. Despite the foundation in different disciplines, during the seminar it became apparent that the different perspectives, approaches, and methodologies used to assess negotiations, auctions, and markets were highly interrelated and an excellent tool box to achieve a holistic view on the object of research. Although this was not unexpected, the success of the seminar and its interdisciplinary exchange of ideas gave further encouragement for the persual of research without confinement by traditional boundaries of disciplines.

Therapiddevelopmentandadoptionoftechnology-basedinformation,commu- cationandproductdeliverysystemshavefacilitatedglobalizationofthe?nancial services industry and removed the barriers between its vertical segments. New business and market models require the adaptation of existing IT infrastr- tures as well as the development of innovative solutions for both experimental and operational systems. In this context, several aspects are creating a highly innovative and at the same time competitive setup in the ?nancial industry. In the workshop series on enterprise applications and services in the ?nance industry (FinanceCom), we try to capture this development. Here, service-oriented computing concepts and architecturesplayamajorrole.Whenapplyingthesenovelconceptsintheba- ing and?nancesector,thebusiness valueofsucharchitectureshasto beassessed quantitatively. Also, the heterogeneous and evolving service-oriented modeling methodologies have to be evaluated. Pulling these novel modeling methodo- gies up to a larger picture, the technology-driventransformation of the ?nancial industry is emphasized, where a highly fragmented and heterogeneous situation is currently developing towards banking value networks.In this ?eld, ?nancial business standardization and the introduction of st- dardized service modules play a core role. Applying standardized services c- tainly allows one to utilize economies of scale in a better way and hence fosters outsourcing and o?shoring tendencies in the sector of banking information s- tems. While addressing this aspect, of course novel technologies that are being developedin other ?elds also entering the banking and ?nance domain.Web s- vicesandgridcomputing aretwo importantexamples.However,thesestandards can only be utilized when being applied homogeneously in ?nancial systems. As an example, international standards such as the "markets and ?nancial inst- ments directive (MiFID)" of the European Union are of key interest.

This book constitutes the proceedings of the 4th International Workshop on Enterprise Applications and Services in the Finance Industry, FinanceCom2008, held in Paris, France, on December 13, 2008. The workshop spans multiple disciplines, including technical, economic, sociological and behavioral sciences. The guiding theme of this workshop was concerned with innovations in the financial services industry, driven by either new business models or changed regulations. The nine presented papers and the keynote speech were carefully reviewed and selected from numerous submissions. The topics covered are financial markets and customers, service-oriented architectures, and regulation and compliance.

The 7th Workshop on e-Business (WeB 2008) was held on December 13, 2008, in Paris. As a pre-ICIS workshop, it provided an open forum for e-business - searchersandpractitionerstoshareresearch?ndings,explorenovelideas,discuss success stories and lessons learned, and map out major challenges with regard to the design of e-business systems. The workshop theme was "Designing e-Business Systems: Markets, Services and Networks." With WeB 2008 having been located in Europe, we wanted to highlight the increasing importance of the design science approach for infor- tionsystemsresearch,which hasa longtraditionin theEuropeanIS community. We received a large number of submissions that addressed key issues speci?c to the workshop theme as well as e-business in general. Based on a rigorous review process, a total of 31 full papers and 30 research-in-progresspapers were accepted for presentation at the workshop, covering a broad range of technical, empirical, managerial,and economic aspects of e-business. Of the 31 full papers, 17 selected papers are contained in this volume of Lecture Notes in Business Information Processing. We hope that you will ?nd them an interesting read and that you will bene?t from the authors' ?ne contributions.

Driven by maturing Web service technologies and the wide acceptance of the service-oriented architecture paradigm, the software industry’s traditional business models and strategies have begun to change: software vendors are turning into service providers. In addition, in the Web service market, a multitude of small and highly specialized providers offer modular services of almost any kind and economic value is created through the interplay of various distributed service providers that jointly contribute to form individualized and integrated solutions. This trend can be optimally catalyzed by universally accessible service orchestration platforms – service value networks (SVNs) – which are the underlying organizational form of the coordination mechanisms presented in this book.Here, the authors focus on providing comprehensive business-oriented insights into today’s trends and challenges that stem from the transition to a service-led economy. They investigate current and future Web service business models and provide a framework for Web service value networks. Pricing mechanism basics are introduced and applied to the specific area of SVNs. Strategies for platform providers are analyzed from the viewpoint of a single provider, and so are pricing mechanisms in service value networks which are optimal from a network perspective. The extended concept of pricing Web service derivatives is also illustrated. The presentation concludes with a vision of how Web service markets in the future could be structured and what further developments can be expected to happen.This book will be of interest to researchers in business development and practitioners such as managers of SMEs in the service sector, as well as computer scientists familiar with Web technologies. The book’s comprehensive content provides readers with athorough understanding of the organizational, economic and technical implications of dealing with Web services as the nucleus of modern business models, which can be applied to Web services in general and Web service value networks specifically..
