In our theoretical model, physicians are faced with a heterogeneous patient population, in which patients systematically vary with regard to both their responsiveness to the provided quality of care and their state of health. We test the behavioral predictions derived from this model in a controlled laboratory experiment. In line with the model, we observe that competition significantly improves patient benefits as long as patients are able to respond to the quality provided. For those patients, who are not able to choose a physician, competition even decreases the patient benefit compared to a situation without competition. This decrease is in contrast to our theoretical prediction implying no change in benefits for passive patients. Deviations from patient-optimal treatment are highest for passive patients in need of a low quantity of medical services. With repetition, both, the positive effects of competition for active patients as well as the negative effects of competition for passive patients become more pronounced. Our results imply that competition can not only improve but also worsen patient outcome and that patients’ responsiveness to quality is decisive.}}, author = {{Brosig-Koch, Jeannette and Hehenkamp, Burkhard and Kokot, Johanna}}, journal = {{Health Economics}}, keywords = {{physician competition, patient characteristics, heterogeneity in quality responses, fee-for-service, laboratory experiment}}, title = {{{Who benefits from quality competition in health care?

The model is relevant in markets such as public health care, education and schooling, or postal services. We find that, when the regulated price is low or intermediate, the entrant strategically locates towards the corner of the market to keep the incumbent at the low monopoly quality level. For a high price, the entrant locates at the corner of the market and both providers implement higher quality compared to a monopoly. In any case, the entrant implements higher quality than the incumbent provider. Social welfare is always higher in a duopoly if the cost of quality is low. For higher cost levels welfare is non-monotonic in the price and it can be optimal to the regulator not to use its entire budget. Therefore, the welfare effect of entry depends on the price and the size of the entry cost, and the regulator should condition the decision to allow entry on an assessment of the entry cost.}}, author = {{Hehenkamp, Burkhard and Kaarbøe, Oddvar M.}}, keywords = {{Quality competition, Price regulation, Location choice, Product differentiation}}, title = {{{Price Regulation, Quality Competition and Location Choice with Costly Relocation}}}, year = {{2023}}, } @article{44077, author = {{Maack, Marten}}, issn = {{0167-6377}}, journal = {{Operations Research Letters}}, keywords = {{Applied Mathematics, Industrial and Manufacturing Engineering, Management Science and Operations Research, Software}}, number = {{3}}, pages = {{220--225}}, publisher = {{Elsevier BV}}, title = {{{Online load balancing on uniform machines with limited migration}}}, doi = {{10.1016/j.orl.2023.02.013}}, volume = {{51}}, year = {{2023}}, } @inproceedings{44194, author = {{Ahmed, Qazi Arbab and Awais, Muhammad and Platzner, Marco}}, booktitle = {{The 24th International Symposium on Quality Electronic Design (ISQED'23), San Francisco, Califorina USA}}, location = {{San Fransico CA 94023-0607, USA}}, title = {{{MAAS: Hiding Trojans in Approximate Circuits}}}, year = {{2023}}, } @article{44897, author = {{Kaimann, Daniel and Spiess Bru, Clarissa Laura Maria and Frick, Bernd}}, journal = {{Journal of Wine Economics}}, title = {{{Ratings Meet Prices: The Dynamic Relationship of Quality Signals}}}, year = {{2023}}, } @inproceedings{45188, author = {{Werthmann, Julian and Scheideler, Christian and Coy, Sam and Czumaj, Artur and Schneider, Philipp}}, title = {{{Routing Schemes for Hybrid Communication Networks}}}, doi = {{10.48550/ARXIV.2210.05333}}, year = {{2023}}, } @inproceedings{45193, author = {{Dou, Jinfeng and Götte, Thorsten and Hillebrandt, Henning and Scheideler, Christian and Werthmann, Julian}}, booktitle = {{Proc. of the 42nd ACM Symposium on Principles of Distributed Computing (PODC '23)}}, location = {{Orlando, USA}}, title = {{{Brief Announcement: Distributed Construction of Near-Optimal Compact Routing Schemes for Planar Graphs}}}, year = {{2023}}, } @inproceedings{44855, abstract = {{Market transactions are subject to information asymmetry about the delivered value proposition, causing transaction costs and adverse market effects among buyers and sellers. Information systems research has investigated how review systems can reduce information asymmetry in business-to-consumer markets. However, these systems cannot be readily applied to business-to-business markets, are vulnerable to manipulation, and suffer from conceptual weak spots since they use textual data or star ratings. Building on design science research, we conceptualize a new class of reputation systems based on monetary-based payments as quantitative ratings for each transaction stored on a blockchain. Using cryptography, we show that our system assures content confidentiality so that buyers can share and sell their ratings selectively, establishing a reputation ecosystem. Our prescriptive insights advance the design of reputation systems and offer new paths to understanding the antecedents, dynamics, and consequences to reduce information asymmetry in B2B transactions.}}, author = {{Hemmrich, Simon and Bobolz, Jan and Beverungen, Daniel and Blömer, Johannes}}, booktitle = {{ECIS 2023 Research Papers}}, title = {{{Designing Business Reputation Ecosystems — A Method for Issuing and Trading Monetary Ratings on a Blockchain}}}, year = {{2023}}, } @inproceedings{43027, author = {{Seutter, Janina and Bartelheimer, Christian and Kundisch, Dennis}}, booktitle = {{Proceedings of the 18th International Conference on Design Science Research in Information Systems and Technology}}, location = {{Pretoria, South Africa}}, title = {{{Supporting Innovation through B2B Reviews – A Taxonomy of B2B Online Review Environments}}}, year = {{2023}}, } @article{45192, author = {{Götte, Thorsten and Hinnenthal, Kristian and Scheideler, Christian and Werthmann, Julian}}, journal = {{Distributed Computing}}, title = {{{Time-Optimal Construction of Overlays}}}, doi = {{https://doi.org/10.1007/s00446-023-00442-4}}, year = {{2023}}, } @inproceedings{40063, author = {{Jabr, Wael and Gutt, Dominik and Neumann, Jürgen and Kundisch, Dennis}}, booktitle = {{Proceedings of the 45th ISMS Marketing Science Conference}}, location = {{Miami, USA}}, title = {{{Updating at the Expense of Demand?
