Die vorliegende Dissertation präsentiert eine umfassende Analyse und Strukturierung des Marktes für netzbasierte Dienste. Basierend auf einer detaillierten Untersuchung des ASP-Angebotes und der ASP-Nachfrage in Europa werden geeignete Institutionen und Informationssubstitute für die Anpassung (Matching) des ASP-Angebotes und der ASP-Nachfrage identifiziert und getestet. Die Strukturierung der Angebotsseite umfasst neben der Bewertung der Marktlage die Entwicklung der ASP-Wertschöpfungskette, die Einordnung in die Systematik der digitalen Güter, die Beschreibung der ASP-Technologien und -Geschäftsmodelle und den Vergleich des ASP-Geschäftsmodells mit der klassischen Softwarenutzung und dem Konzept der virtuellen Organisationen. Die Ergebnisse der Untersuchungen zeigen vorhandene Defizite in der Informations- und Kommunikationspolitik der ASP-Angebotsseite auf. Für die Strukturierung der Nachfrageseite für netzbasierte Dienste werden die Theorien der Auslagerung (Outsourcing) von Informationstechnologien, die Methoden und Instrumente der Kosten- und Nutzenmessung und die Theorie der Transaktionsphasen der Auslagerung angewendet. Kern der wissenschaftlichen Untersuchung bildet die empirische Untersuchung des ASP-Nachfragemarktes in Deutschland und anderen europäischen Ländern. Die Erkenntnisse der Analyse des ASP-Angebotes und der ASP-Nachfrage werden gegenübergestellt und Methoden zur Abstimmung von ASP-Angebot und Nachfrage mit Hilfe der Transaktionskostentheorie und den Theorien der Informations- und Institutionenökonomie abgeleitet. Barrieren, Intransparenzen und Informationsasymmetrien werden auf beiden Seiten aufgezeigt und darauf aufbauend Informationssubstitute für netzbasierte Dienste identifiziert. Erfahrungs- und Vertrauenseigenschaften werden mit Hilfe von Informationssubstituten in einem Onlinebefragungsexperiment hinsichtlich der Wahrnehmung, Wirkung und möglicher Zahlungsbereitschaften überprüft. Aus den Ergebnissen des Onlinebefragungsexperimentes werden Anforderungen an die Informations- und Kommunikationspolitik und Strategien zur Reduzierung der Informationsasymmetrie für netzbasierte Dienste entwickelt. Das Ergebnis der Arbeit ist die Ableitung relevanter Kriterien für die Darstellung und Bewertung der Leistungsbündel netzbasierter Dienste und die Entwicklung von Strategien zur Reduzierung der Transaktionsunsicherheit durch die Identifizierung und Integration von Informationssubstituten für netzbasierte Dienste. / This dissertation presents a comprehensive analysis and conceptual framework of the web-based Application Service Provider (ASP) market. Based on a detailed analysis of ASP supply and demand in Europe, appropriate institutions and information substitutes for the matching process on the ASP market are identified and evaluated. The conceptual framework for the supply side is developed by evaluating the market situation, designing an ASP value chain, classifying digital goods, describing the ASP technologies and business models. These are then compared with the classic model of software utilization and the concept of virtual organizations. The results indicate present deficits in the supply-side information and communication policy. For ASP demand, theories of outsourcing of information technologies, methods and instruments of cost-and-utility-measuring and the theory of transaction phases of outsourcing are used. The basis for both supply-side and demand-side evaluations is an empirical analysis of the European ASP market. We compare the outcome of the supply and demand analyses and derive methods for their coordination by the transaction cost theory and the theories of information and institution economy. Barriers, lack of transparencies and information asymmetries are identified on both sides and thus, information substitutes for web-based services are developed. Information substitutes for experience and trust characteristics are evaluated with an online-questionnaire completed by key participants based on their perception, action and willingness to pay. From those results, we deduce strategies for reducing the information asymmetry. The result of the work is the deduction of relevant criteria for the presentation and evaluation for the supply of web-based services and the development of strategies for reducing the transaction uncertainty by identifying and integrating information substitutes.

This research identified that e-commerce is growing annually and has a significant impact on the South African economy. When the Minister of Finance announced that VAT registration would become compulsory for foreign suppliers importing e-commerce transactions into South Africa, there were many speculations regarding the implication this will have for South Africa. The main objectives for the research are to determine whether the current VAT structure and VAT Act in South Africa will be able to support the proposal made by the Minister of Finance and what possible challenges should be considered regarding VAT on e-commerce transactions that were already identified by other countries. It will further be considered whether the proposal is in line with current international legislation and trends. Therefore, the development and implementation of VAT on e-commerce transactions in the European Union and New Zealand were researched and discussed to obtain an understanding of the similar current VAT systems in other parts of the world. It was identified during the research that there are still challenges experienced with the implementation of VAT on e-commerce transactions. The challenges range from the anonymity of the parties to the identification of the permanent establishment of the supplier, which are discussed in detail. These challenges can lead to tax evasion and the erosion of a country’s revenue base. The proposal by the Minister of Finance is found to be in line with other countries’ implementation of VAT on e-commerce transactions. Furthermore, South Africa’s current VAT system was analysed to ascertain whether it is sufficient to implement VAT on e-commerce transactions. Currently, SARS is dependent on the consumer’s honesty to declare the VAT on all e-commerce transactions. It was further identified that there are challenges relating to the implementation of VAT on ecommerce transactions as it is lacking place of supply rules, which often creates uncertainty about whether a product is subject to VAT. It was found in the study that the current VAT system would not be sufficient to support the proposal made by the Minister of Finance without an amendment to the VAT system to secure the income from the consumption tax on e-commerce transactions. It was further found that there are worldwide still challenges experienced with the implementation of VAT on e-commerce transactions. Recommendations were made for further research relating to the new Tax Bill that is due to be released in 2014 and the impact it will have on the South African economy. / MCom (South African and International Taxation), North-West University, Potchefstroom Campus, 2014

Im Zuge der ersten Postreform wurde als "öffentliches Unternehmen" ohne volle Rechtspersönlichkeit auch die Deutsche Bundespost POSTBANK errichtet und aus der Staatsverwaltung ausgegliedert. Der Beitrag erläutert die Organisationsstruktur einschließlich des Verhältnisses zu den Schwesterunternehmen DBP POSTDIENST und DBP TELEKOM sowie die nunmehr privatrechtlich ausgestalteten Kundenbeziehungen und befaßt sich auch mit den fortbestehenden Beschränkungen für bankgeschäftliche Aktivitäten.
