Abstract (De)
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.
