On such markets, service providers offer services that can be flexibly combined with each other. However, most often, market participants are not able to individually estimate the quality of traded services in advance. As a consequence, even potentially profitable transactions between customers and providers might not take place. In the worst case, this can induce a market failure. To overcome this problem, we propose the incorporation of reputation information as an indicator for expected service quality. We address On-The-Fly Computing as a representative environment of markets of composed services. In this environment, customers provide feedback on transactions. We present a conceptual design of a reputation system which collects and processes user feedback, and provides it to participants in the market. Our contribution includes the identification of requirements for such a reputation system from a technical and an economic perspective. Based on these requirements, we propose a flexible solution that facilitates the incorporation of reputation information into markets of composed services while simultaneously preserving privacy of customers who provide feedback. The requirements we formulate in this paper have just been partially met in literature. An integrated approach, however, has not been addressed yet.}}, author = {{Brangewitz, Sonja and Jungmann, Alexander and Petrlic, Ronald and Platenius, Marie Christin}}, booktitle = {{Proceedings of the 6th International Conferences on Advanced Service Computing (SERVICE COMPUTATION)}}, pages = {{49--57}}, title = {{{Towards a Flexible and Privacy-Preserving Reputation System for Markets of Composed Services}}}, year = {{2014}}, } @article{3491, author = {{Becker, Jörg and Beverungen, Daniel and Knackstedt, Ralf and Peter Rauer, Hans and Sigge, Daniel}}, journal = {{Information Systems and e-Business Management}}, number = {{3}}, pages = {{337----365}}, title = {{{On the Ontological Expressiveness of Conceptual Modeling Grammars for Service Productivity Management}}}, doi = {{10.1007/s10257-013-0219-y}}, year = {{2014}}, } @article{3492, author = {{Beverungen, Daniel}}, journal = {{Business and Information Systems Engineering}}, number = {{4}}, pages = {{191----202}}, title = {{{Exploring the Interplay of the Design and Emergence of Business Processes as Organizational Routines}}}, doi = {{10.1007/s12599-014-0335-3}}, year = {{2014}}, } @article{3493, author = {{Beverungen, Daniel}}, journal = {{WIRTSCHAFTSINFORMATIK}}, number = {{4}}, pages = {{209----222}}, title = {{{Über das Zusammenwirken der Gestaltung und Emergenz von Geschäftsprozessen als Organisationsroutinen}}}, doi = {{10.1007/s11576-014-0425-3}}, year = {{2014}}, } @techreport{350, abstract = {{Customers continuously evaluate the credibility and reliability of a range of signals both separately and jointly. However, existing econometric studies pay insufficient attention to the interactions and complex combinations of these signals, and are typically limited as a result of difficulties controlling for multicollinearity and endogeneity in their data. We develop a novel theoretical approach to address these issues and study different signaling effects (i.e., word-of-mouth, brand reputation, and distribution strategy) on customer perceptions. Using data on the US video games market, we apply a fuzzy set qualitative comparative analysis (fsQCA) to account for cause-effect relationships. The results of our study address a number of key issues in the economics and management literature. First, our results support the contention that reviews from professional critics act as a signal of product quality and therefore positively influence unit sales, as do the discriminatory effects of prices and restricted age ratings. Second, we find evidence to support the use of brand extension strategies as marketing tools that create spillover effects and support the launch of new products.}}, author = {{Kaimann, Daniel and Cox, Joe}}, publisher = {{Universität Paderborn}}, title = {{{The Interaction of Signals: A Fuzzy set Analysis of the Video Game Industry}}}, year = {{2014}}, } @phdthesis{352, author = {{Scheel, Friedrich}}, publisher = {{Universität Paderborn}}, title = {{{The Economics of Individual Behavior in Competitive Environments: Empirical Evidence from Real-Life Tournaments}}}, year = {{2014}}, } @inproceedings{3538, author = {{Rötzmeier-Keuper, Julia and Wünderlich, Nancy}}, booktitle = {{ Proceedings of the 39th Annual Macromarketing Conference}}, location = {{London, GB}}, title = {{{Customer collectives in healthcare: The transformative potential of service to overcome consumer vulnerability}}}, year = {{2014}}, } @inproceedings{3541, author = {{Rötzmeier-Keuper, Julia and Wünderlich, Nancy}}, booktitle = {{Proceedings of the AMA SERVSIG International Service Research Conference}}, location = {{Thessaloniki, GR}}, title = {{{ Interdependent Relationships Between and among Service Providers and Customer Collectives.}}}, year = {{2014}}, } @phdthesis{358, author = {{Röhl, Nils}}, publisher = {{Universität Paderborn}}, title = {{{Strategic and Cooperative Games in Network Economics}}}, year = {{2014}}, } @misc{362, author = {{Kaiser, Sarah}}, publisher = {{Universität Paderborn}}, title = {{{Signalisieren und Screening in Arbeitsmärkten - die Experimente von Brandts & Holt und Kübler et. al}}}, year = {{2014}}, } @article{3699, abstract = {{When taxes on capital or wealth are levied, in most countries companies have to be assessed in terms of their market value (MV). Estimating the MV of private companies for tax purposes is a challenging task for tax authorities as MVs are not available. In this study, I empirically analyse to what extent an accounting-based tax valuation method for private companies, a simplified residual income model, succeeds in matching the MV. I refer to the mandatory Standardised Combination Model that is a special case of methods commonly used in several countries. In the absence of market prices for private companies, I use a sample of small German public companies as a proxy. I validate this approach using a sensitivity analysis that involves matching the sample of public companies with that of private companies. The results imply that the mandatory Standardised Combination Model leads to a severe unequal treatment not only between public and private companies but also among private companies across and within industries. Furthermore, I simulate the effects of variation in the key parameters and highlight their impact on the approximation quality of the Standardised Combination Method. The findings are relevant to tax reform discussions as well as to tax policy-makers and practitioners in many countries.}}, author = {{Müller, Jens}}, journal = {{European Accounting Review}}, keywords = {{Challenge of Assessing, Tax Purposes}}, number = {{1}}, pages = {{117----141}}, title = {{{The challenge of assessing the market value of private companies using a standardised combination method for tax purposes--Lessons to be learnt from past experience}}}, year = {{2014}}, } @inproceedings{382, abstract = {{This paper explores how cloud provider competition influences instance pricing in an IaaS (Infrastructure-as-a-Service) market.

We investigate a duopoly of providers and analyze stable market prices in two-part tariffs. Further, we study offers that allow a specified amount of included usage (three-part tariffs). Neither two-part nor three-part tariffs produce an equilibrium market outcome other than a service pricing that equals production cost, i.e., complex price structures do not significantly affect the results from ordinary Bertrand competition.}}, author = {{Künsemöller, Jörn and Brangewitz, Sonja and Karl, Holger and Haake, Claus-Jochen}}, booktitle = {{Proceedings of the 2014 IEEE International Conference on Services Computing (SCC)}}, pages = {{203--210}}, title = {{{Provider Competition in Infrastructure-as-a-Service}}}, doi = {{10.1109/SCC.2014.35}}, year = {{2014}}, } @inproceedings{2707, author = {{Mutter, Tobias and Kundisch, Dennis}}, booktitle = {{Proceedings of the International Conference on Information Systems (ICIS)}}, location = {{Auckland, Neuseeland}}, title = {{{Behavioral Mechanisms Prompted by Badges: The Goal-Gradient Hypothesis}}}, year = {{2014}}, } @inproceedings{2708, author = {{Herrmann, Philipp}}, location = {{Auckland, Neuseeland}}, title = {{{The Hunt for Quality in a Market: Exploring the Relationship between Local Market Structure and Digitized Customer Experience}}}, year = {{2014}}, } @article{2709, abstract = {{This paper studies welfare consequences of consumer-side market transparency with endogenous entry of firms. Different from most studies, we consider the unique symmetric entry equilibrium, which is in mixed strategies. We identify two effects of market transparency on welfare: a competition effect and a novel market-structure effect. We show, surprisingly, that for almost all demand functions the negative market-structure effect eventually dominates the positive competition effect as the market becomes increasingly transparent. Consumer-side market transparency can therefore be socially excessive even without collusion.
