Asymmetries between intermediaries may arise due to distinct product qualities as well as by reasons of different production technologies. The intermediaries compete on the output market by choosing production quantities sequentially and for the supplies of a monopolistic input supplier on the input market. It turns out that there exist differences in product quality and productivities such that an intermediary being the Stackelberg leader has no incentive to procure inputs, whereas in the role of the Stackelberg follower will participate in the market. Moreover, we find that given an intermediary is more competitive, his equilibrium output quantity is higher when being the leader than when being the follower. Interestingly, if the intermediary is less competitive and goods are complements, there may exist asymmetries such that an intermediary being in the position of the Stackelberg follower offers higher output quantities in equilibrium than when being in the position of the Stackelberg leader.}}, author = {{Manegold, Jochen}}, keywords = {{Input Market, Product Quality, Quantity Competition, Stackelberg Competition, Product Innovation}}, publisher = {{CIE Working Paper Series, Paderborn University}}, title = {{{Stackelberg Competition among Intermediaries in a Differentiated Duopoly with Product Innovation}}}, volume = {{98}}, year = {{2016}}, } @article{2618, author = {{Betz, Stefan}}, journal = {{ForschungsForum Paderborn}}, pages = {{pp. 46--53}}, title = {{{Auswahl internationaler Standorte - Wie lassen sich Standortentscheidungen methodisch unterstützen?}}}, volume = {{19}}, year = {{2016}}, } @article{2687, author = {{Kamhöfer, Daniel A. and Schmitz, Hendrik}}, issn = {{0883-7252}}, journal = {{Journal of Applied Econometrics}}, number = {{5}}, pages = {{912--919}}, publisher = {{Wiley-Blackwell}}, title = {{{Reanalyzing Zero Returns to Education in Germany}}}, doi = {{10.1002/jae.2461}}, volume = {{31}}, year = {{2016}}, } @inproceedings{3283, author = {{Bräuer, sebastian and Monhof, Markus and Klör, Benjamin and Beverungen, Daniel}}, booktitle = {{Proceedings of the IEEE Conference on Business Informatics (CBI 2016)}}, location = {{Paris, France}}, title = {{{Residential Energy Storage from Repurposed Electric Vehicle Batteries — Market Overview and Development of a Service-Centered Business Model}}}, year = {{2016}}, } @misc{3308, author = {{Breuer, Robin }}, publisher = {{Universität Paderborn}}, title = {{{Monitoring in Franchise-Netzwerken: Eine ökonomische Analyse}}}, year = {{2016}}, } @misc{3311, author = {{Amedick, Michaela}}, publisher = {{Universität Paderborn}}, title = {{{Informationsasymmetrien auf dem Spendenmarkt und Möglichkeiten ihrer Reduktion: Eine Prinzipal-Agenten-Perspektive von Online Spenden}}}, year = {{2016}}, } @article{3318, author = {{Melnikov, Vitalik and Hüllermeier, Eyke and Kaimann, Daniel and Frick, Bernd and Gupta, Pritha }}, issn = {{2083-8476}}, journal = {{Schedae Informaticae}}, publisher = {{Uniwersytet Jagiellonski - Wydawnictwo Uniwersytetu Jagiellonskiego}}, title = {{{Pairwise versus Pointwise Ranking: A Case Study}}}, doi = {{10.4467/20838476si.16.006.6187}}, volume = {{25}}, year = {{2016}}, } @inproceedings{2699, author = {{Görzen, Thomas and Kundisch, Dennis}}, booktitle = {{Proceedings of the 22nd Americas' Conference on Information Systems (AMCIS)}}, location = {{San Diego, USA}}, title = {{{Can the Crowd Substitute Experts in Evaluation of Creative Ideas?

Auf der Basis von realen Jahresabschlussdaten wird eine mehrperiodige Veranlagungssimulation durchgeführt, die insbesondere ermöglicht, den zu erwartenden Eigenkapitalverzehr sowie den Anstieg der Steuerbelastung für die betrachtete Stichprobe zu quantifizieren. Von besonderem Interesse sind hierbei Unternehmen, deren laufende Erträge nicht ausreichen, um die Belastungen durch die Vermögensteuer zu tragen und damit einem Substanzverzehr ausgesetzt sind. Es zeigt sich, dass etwa die Hälfte der Unternehmen im Untersuchungszeitraum von sechs Jahren in mindestens einem Jahr einen Substanzverzehr erfährt. Der Vermögensteuer kommt somit keinesfalls der vielfach postulierte Charakter einer eher mäßig belastenden und im Wesentlichen substanzverschonenden Steuer zu.
