A triadic constellation may arise in the context of services for animal companions, for example, when veterinarians provide counsel and treatment to the animal companion and its owner. Through interviews with both owners of animal companions and providers of services for animal companions, this study explores typical constellations and characteristics of the three relationships in this service triad. In line with balance theory, the results show that four distinct types of triadic relationships exist in services for animal companions: the harmonious, the dysfunctional, the challenging, and the doubtful triad. The study highlights the potential conflicts and dynamics in the triads to advise providers on how to address customers depending on the types of triads to which they belong.}}, author = {{Rötzmeier-Keuper, Julia and Hendricks, Jennifer and Wünderlich, Nancy and Schmitz, Gertrud}}, journal = {{Journal of Business Research}}, keywords = {{Triadic relationships, Balance theory, Pet-related services, Animal companions, Service relationship typology, Service triads}}, number = {{85}}, pages = {{295----303}}, publisher = {{Elsevier}}, title = {{{Triadic relationships in the context of services for animal companions}}}, year = {{2018}}, } @article{3520, author = {{Pelster, Matthias and Hofmann, Annette}}, journal = {{Journal of Banking & Finance}}, title = {{{About the Fear of Reputational Loss: Social Trading and the Disposition Effect}}}, doi = {{10.1016/j.jbankfin.2018.07.003}}, year = {{2018}}, } @inproceedings{3550, abstract = {{Nowadays companies like Apple create ecosystems of third- party providers and users around their software platforms. Often online stores like Apple App Store are created to directly market third-party solutions. We call such ecosystems store-oriented software ecosystems. While the architecture of these ecosystems is mainly derived from busi- ness decisions of their owners, ecosystems with greatly different archi- tectural designs have been created. This diversity makes it challenging for future ecosystem providers to understand which architectural design is suitable to fulfill certain business decisions. In turn, opening a plat- form becomes risky while endangering intellectual property or scarifying quality of services. In this paper, we identify three main design options of store-oriented software ecosystems by classifying existing ecosystems based on similarities in their business decisions. We elaborate on the design options, discuss their main contributions, and provide exemplary ecosystems. Our work provides aspiring ecosystem providers with the reusable knowledge of existing ecosystems and helps them to take more informed architectural decisions and reduce risks in future.}}, author = {{Jazayeri, Bahar and Zimmermann, Olaf and Engels, Gregor and Küster, Jochen and Kundisch, Dennis and Szopinski, Daniel}}, booktitle = {{Proceeding of International Symposium on Business Modeling and Software Design}}, isbn = {{9783319942131}}, issn = {{1865-1348}}, pages = {{390--400}}, publisher = {{Springer}}, title = {{{Design Options of Store-Oriented Software Ecosystems: An Investigation of Business Decisions}}}, doi = {{10.1007/978-3-319-94214-8_30}}, volume = {{319}}, year = {{2018}}, } @inbook{3742, author = {{Hoof, Simon}}, booktitle = {{Static & Dynamic Game Theory: Foundations & Applications}}, isbn = {{9783319929873}}, issn = {{2363-8516}}, pages = {{13--23}}, publisher = {{Springer International Publishing}}, title = {{{Dynamic Voluntary Provision of Public Goods: The Recursive Nash Bargaining Solution}}}, doi = {{10.1007/978-3-319-92988-0_2}}, year = {{2018}}, } @article{3902, abstract = {{All over the world, firms and governments are increasingly concerned about the rise in tax complexity. To manage it and develop effective simplification measures, detailed information on the current drivers of complexity is required. However, research on this topic is scarce. This is surprising as the latest developments-for example, those triggered by the BEPS project-have given rise to the conjecture that complexity drivers may have changed, thus questioning the findings of prior studies. In this article, we shed light on this issue and provide a global picture of the current drivers of tax complexity that multinational corporations face based on a survey of 221 highly experienced tax consultants from 108 countries. Our results show that prior complexity drivers of the tax code are still important, with details and changes of tax regulations being the two most important complexity drivers. We also find evidence for new important complexity drivers emerging from different areas of the tax framework, such as inconsistent decisions among tax officers (tax audits) or retroactively applied tax law amendments (tax enactment). Based on the tax consultants' responses, we develop a concept of tax complexity that is characterized by two pillars, tax code and tax framework complexity and illustrates the various aspects that should be considered when assessing the complexity of a country's tax system.}}, author = {{Hoppe, Thomas and Schanz, Deborah and Sturm, Susann and Sureth-Sloane, Caren}}, issn = {{ 0165-2826}}, journal = {{Intertax}}, number = {{8/9}}, pages = {{654--675}}, publisher = {{Kluwer Law International}}, title = {{{What are the Drivers of Tax Complexity for MNCs?

With the help of the two treatments, we vary the relative reciprocity between the physician and the two other actors, briber and patient. Additionally we use a follow up questionnaire to measure the behavioral motivation of the participants. We find that reciprocity leads to bribery relationships: In the partner treatment physicians act corruptly more often.
