We find, for exogenously given participation probabilities, players exert more effort under the concept of a finite-population evolutionarily stable strategy (FPESS) than under Nash equilibrium (NE). We show that there is ex-ante overdissipation under FPESS for sufficiently large participation probabilities, if, and only if, the impact function is convex. With costly endogenous entry, players enter the contest with a higher probability and exert more effort under FPESS than under NE. Importantly, under endogenous entry, overdissipation can occur for all (Tullock) contest success functions, in particular those with concave impact functions."}],"project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Project Area A","_id":"2"},{"_id":"7","name":"SFB 901 - Subproject A3"}],"publication":"Journal of Economic Behavior & Organization","citation":{"short":"Y.

We find that when engaging in cryptocurrency trading investors simultaneously increase their risk-seeking behavior in stock trading as they increase their trading intensity and use of leverage. The increase in risk-seeking in stocks is particularly pronounced when volatility in cryptocurrency returns is low, suggesting that their overall behavior is driven by excitement-seeking.

One manufacturer exclusively sells his good to one retailer, whereas the other manufacturer sells his good to both retailers. Thus, one retailer is a monopolist for one product but competes with the other retailer in the second product market. The two-product retailer has the option to bundle his goods or to sell them separately. We find that bundling aggravates the double marginalization problem for the bundling retailer. Nevertheless, when the retailers compete in prices, bundling can be more profitable than separate selling for the retailer as bundling softens the retail competition. The ultimate outcome depends on the manufacturers’ marginal costs. Given retail quantity competition, however, bundling is in no case the retailer’s best strategy. Furthermore, we show that profitable bundling reduces consumer and producer surplus in the equilibrium."}],"department":[{"_id":"280"},{"_id":"475"}],"keyword":["retail bundling","leverage theory","double marginalization"],"type":"report","date_created":"2019-06-28T08:42:49Z","file":[{"creator":"jheinzel","date_created":"2019-06-28T08:44:52Z","relation":"main_file","date_updated":"2019-06-28T08:44:52Z","file_name":"WP120.pdf","file_size":375054,"access_level":"closed","file_id":"10333","content_type":"application/pdf","success":1}]},{"publication":"Proceedings of the 40th International Conference on Information Systems (ICIS)","citation":{"mla":"Bohn, Nicolai, and Dennis Kundisch. “All Things Considered? – Technology Design Decision-Making Characteristics in Digital Startups.” <i>Proceedings of the 40th International Conference on Information Systems (ICIS)</i>, 2019.","bibtex":"@inproceedings{Bohn_Kundisch_2019, title={All Things Considered? – Technology Design Decision-making Characteristics in Digital Startups}, booktitle={Proceedings of the 40th International Conference on Information Systems (ICIS)}, author={Bohn, Nicolai and Kundisch, Dennis}, year={2019} }","ama":"Bohn N, Kundisch D.

The issues are the rapid digitalization and development of health and welfare technology, which presently is mainly technology driven (not need or user driven), and the demographic challenge. The aim of the study was to explore older adults’ perception of the future use of welfare technology or care robots. A qualitative approach with focus group discussions was employed, followed by thematic analysis. The results are presented in four overall themes: the impact on daily life for older adults and professional caregivers, codes of practice and terms of use, dissemination of information and knowledge, and conditions for successful implementation. There were significant differences in the informants’ attitudes toward and knowledge about care robots. However, the informants’ attitudes appeared to change during the focus groups and in general, became more positive. Authentic needs, which care robots could support, refer to independence, safety and security, and the ability to manage or ease daily life or working life. The results suggest that older adults, after receiving relevant information, were open to the idea of being supported by care robots in their daily lives."}],"date_created":"2019-03-22T07:27:48Z","department":[{"_id":"178"},{"_id":"184"}],"keyword":["Care robots","Older adults","Implementation","Information","Perceptions","Welfare technology"],"type":"conference","publication_identifier":{"isbn":["978-3-030-22011-2"]},"author":[{"full_name":"Johansson-Pajala, Rose-Marie","last_name":"Johansson-Pajala","first_name":"Rose-Marie"},{"id":"72497","full_name":"Thommes, Kirsten","last_name":"Thommes","first_name":"Kirsten"},{"id":"73093","full_name":"Hoppe, Julia Amelie","last_name":"Hoppe","first_name":"Julia Amelie"},{"first_name":"Outi","last_name":"Tuisku","full_name":"Tuisku, Outi"},{"full_name":"Hennala, Lea","last_name":"Hennala","first_name":"Lea"},{"full_name":"Pekkarinen, Satu","last_name":"Pekkarinen","first_name":"Satu"},{"full_name":" Melkas, Helinä","last_name":" Melkas","first_name":"Helinä"},{"first_name":"Christine ","last_name":"Gustafsson","full_name":"Gustafsson, Christine "}],"title":"Improved Knowledge Changes the Mindset: Older Adults’ Perceptions of Care Robots","year":"2019","intvolume":"     11592","date_updated":"2022-03-10T15:41:56Z","publication_status":"published","series_title":"Lecture Notes in Computer Science","language":[{"iso":"eng"}],"doi":"10.1007/978-3-030-22012-9_16","citation":{"short":"R.-M.

As a baseline result, we initially find an increase in portfolio (downside) risk-diversification when adding CDS indices, which is observed irrespective of both CDS markets, investor-types and different sub-periods, including the global financial crisis and European sovereign debt crisis. In addition, the analysis reveals higher portfolio excess returns and performance in CDS index portfolios, however, these effects clearly differ between markets, investor-types and sub-periods. Overall, portfolio benefits of adding CDS indices mainly result from the fact that institutional investors replace sovereign bond indices rather than stock indices by CDS indices due to better risk-return characteristics. Our baseline findings remain robust under a variety of robustness checks. Results from sensitivity analyses provide further important implications for institutional investors with a strategic focus on a long-term conservative portfolio management.","lang":"eng"}],"publication":"Review of Derivatives Research ","issue":"2","department":[{"_id":"188"},{"_id":"186"}],"type":"journal_article","keyword":["Corporate credit default swap indices","Mean-variance asset allocation","Out-of-sample portfolio optimization","Portfolio risk-diversification","Portfolio performance evaluation"],"date_created":"2018-10-01T12:17:35Z","intvolume":"        22","article_type":"original","date_updated":"2022-05-04T06:15:02Z","publication_status":"published","author":[{"last_name":"Hippert","first_name":"Benjamin","full_name":"Hippert, Benjamin","id":"48476"},{"id":"36049","orcid":"https://orcid.org/0000-0002-8058-8857","first_name":"André","last_name":"Uhde","full_name":"Uhde, André"},{"full_name":"Wengerek, Sascha Tobias","orcid":"0000-0002-7820-3903","last_name":"Wengerek","first_name":"Sascha Tobias","id":"48837"}],"title":"Portfolio Benefits of Adding Corporate Credit Default Swap Indices: Evidence from North America and Europe","year":"2019","doi":"https://doi.org/10.1007/s11147-018-9148-8","language":[{"iso":"eng"}],"citation":{"apa":"Hippert, B., Uhde, A., &#38; Wengerek, S.

While early AR systems relied on pre-defined trigger images or QR code markers, modern AR applications leverage machine learning techniques to identify objects in their physical environments. So far, only few empirical studies have investigated AR's potential for supporting learning and task assistance using such marker-less AR. In order to address this research gap, we implemented an AR application (app)with the aim to analyze the effectiveness of marker-less AR applied in a mundane setting which can be used for on-the-job training and more formal educational settings. The results of our laboratory experiment show that while participants working with AR needed significantly more time to fulfill the given task, the participants who were supported by AR learned significantly more."}]},{"year":"2019","title":"Fostering pre-service economics teachers´ reflection on their attitudes towards the discipline","status":"public","author":[{"last_name":"Jenert","orcid":" https://orcid.org/0000-0001-9262-5646","first_name":"Tobias","full_name":"Jenert, Tobias","id":"71994"},{"first_name":"Taiga","last_name":"Brahm ","full_name":"Brahm , Taiga"}],"conference":{"end_date":"2019-08-16","location":"Aachen","name":"EARLI Biennial Conference","start_date":"2019-08-12"},"date_updated":"2022-08-17T09:51:20Z","_id":"8519","language":[{"iso":"eng"}],"user_id":"71994","citation":{"bibtex":"@inproceedings{Jenert_Brahm _2019, title={Fostering pre-service economics teachers´ reflection on their attitudes towards the discipline}, author={Jenert, Tobias and Brahm , Taiga}, year={2019} }","ama":"Jenert T, Brahm  T.
