When using these metrics, technical aggregation functions such as the arithmetic mean are implemented to measure the valence of product ratings. However, it is unclear whether the implemented aggregation functions match the inherent aggregation patterns of customers. In our experiment, we elicit customers' aggregation heuristics and contrast these with reference functions. Our findings indicate that, overall, the arithmetic mean performs best in comparison with other aggregation functions. However, our analysis on an individual level reveals heterogeneous aggregation patterns. Major clusters exhibit a binary bias (i.e., an over-weighting of moderate ratings and under-weighting of extreme ratings) in combination with the arithmetic mean. Minor clusters focus on 1-star ratings or negative (i.e., 1-star and 2-star) ratings. Thereby, inherent aggregation patterns are neither affected by variation of provided information nor by individual characteristics such as experience, risk attitudes, or demographics. author: - first_name: Dirk full_name: van Straaten, Dirk id: '10311' last_name: van Straaten - first_name: Vitalik full_name: Melnikov, Vitalik id: '58747' last_name: Melnikov - first_name: Eyke full_name: Hüllermeier, Eyke id: '48129' last_name: Hüllermeier - first_name: Behnud full_name: Mir Djawadi, Behnud id: '26032' last_name: Mir Djawadi orcid: 0000-0002-6271-5912 - first_name: René full_name: Fahr, René id: '111' last_name: Fahr citation: ama: 'van Straaten D, Melnikov V, Hüllermeier E, Mir Djawadi B, Fahr R.

Whereas the theoretical research on network formation under the threat of disruption has thus gained prominence, hardly any experimental research exists so far. In this paper, we therefore experimentally study the emergence of networks including the aspect of a known external threat by relating theoretical predictions by Dzuibiński and Goyal (2013) to actual observed behaviour. We deal with the question if subjects in the role of a strategic Designer are able to form safe networks for least costs while facing a strategic Adversary who is going to attack their networks. Varying the costs for protecting nodes, we designed and tested two treatments with different predictions for the equilibrium network and investigated whether one of the least cost equilibrium networks was more likely to be reached. Furthermore, the influence of the subjects’ farsightedness on their decision-making process was elicited and analysed.\r\n\r\nWe find that while subjects are able to build safe networks in both treatments, equilibrium networks are only built in one of the two treatments. In the other treatment, predominantly safe networks are built but they are not for least costs. Additionally, we find that farsightedness –as measured in our experiment– has no influence on whether subjects are able to build safe or least cost equilibrium networks. Two robustness settings with a reduced external threat or more liberties to modify the initial networks qualitatively confirm our results. Overall, in this experiment observed behaviour is only partially in line with the theoretical predictions by Dzuibiński and Goyal (2013)." article_type: original author: - first_name: Angelika Elfriede full_name: Endres, Angelika Elfriede id: '48794' last_name: Endres - first_name: Sonja full_name: Recker, Sonja last_name: Recker - first_name: Behnud full_name: Mir Djawadi, Behnud id: '26032' last_name: Mir Djawadi orcid: 0000-0002-6271-5912 - first_name: Britta full_name: Hoyer, Britta id: '42447' last_name: Hoyer citation: ama: 'Endres AE, Recker S, Mir Djawadi B, Hoyer B.

In this\r\nstudy we examine the effectiveness of a reputation system to reduce information asymmetries\r\nwhen customers may make mistakes in judging the provided service quality. In our model,\r\na service provider makes strategic quality choices and short-lived customers are asked to\r\nevaluate the observed quality by providing ratings to a reputation system. The customer is\r\nnot able to always evaluate the service quality correctly and possibly submits an erroneous\r\nrating according to a predefined probability. Considering reputation profiles of the last three\r\nsales, within the theoretical model we derive that the service provider’s dichotomous quality\r\ndecisions are independent of the reputation profile and depend only on the probabilities of\r\nreceiving positive and negative ratings when providing low or high quality. Thus, a service\r\nprovider optimally either maintains a good reputation or completely refrains from any reputation\r\nbuilding process. However, when mapping our theoretical model to an experimental\r\ndesign we find that a significant share of subjects in the role of the service provider deviates\r\nfrom optimal behavior and chooses actions which are conditional on the current reputation\r\nprofile. With respect to these individual quality choices we see that subjects use milking\r\nstrategies which means that they exploit a good reputation. In particular, if the sales price\r\nis high, low quality is delivered until the price drops below a certain threshold, and then\r\nhigh quality is chosen until the price increases again." article_number: e0207172 article_type: review author: - first_name: Behnud full_name: Mir Djawadi, Behnud id: '26032' last_name: Mir Djawadi orcid: 0000-0002-6271-5912 - first_name: Rene full_name: Fahr, Rene id: '111' last_name: Fahr - first_name: Claus-Jochen full_name: Haake, Claus-Jochen id: '20801' last_name: Haake - first_name: Sonja full_name: Recker, Sonja last_name: Recker citation: ama: Mir Djawadi B, Fahr R, Haake C-J, Recker S.

We argue that lying in professional contexts share three characterizing features: (1) the gain from the dishonest behavior is uncertain, (2) the harm that lying may cause to the other party is only indirect and (3) lies are more indirect lies by action or written statements. Conducted as a field experiment with a heterogenous group of participants during a University ‘‘Open House Day’’, our ‘‘gumball-machineexperiment’’ provides field evidence on how preferences for lying are shaped in situations typically found in professional contexts which we consider to be particularly prone to lying behavior compared to other contexts. As a key innovation, our experimental design allows measuring exact levels of cheating behavior under anonymous conditions. We find clean evidence that cheating is prevalent across all sub groups and that more than 32% of the population cheats for their own gain. However, an analysis of the cheating rates with respect to highest educational degree and professional status reveals that students cheat more than non-students. This finding warrants a careful interpretation of generalizing laboratory findings with student subjects about the prevalence of cheating in the population.' author: - first_name: Rene full_name: Fahr, Rene id: '111' last_name: Fahr - first_name: Behnud full_name: Mir Djawadi, Behnud id: '26032' last_name: Mir Djawadi orcid: 0000-0002-6271-5912 citation: ama: 'Fahr R, Mir Djawadi B. “…and they are really lying”: Clean Evidence on the Pervasiveness of Cheating in Professional Contexts from a Field Experiment.

Although many fields of studies including epidemiology, sociology, and psychology try to identify determinants for medical nonpersistence, comprehensive research to explain medical nonpersistence from an economics perspective is rather scarce.ObjectivesThe aim of the study was to develop a conceptual framework that augments standard economic choice theory with psychological concepts of behavioral economics to understand how patients’ preferences for discontinuing with therapy arise over the course of the medical treatment. The availability of such a framework allows the targeted design of mechanisms for intervention strategies.MethodsOur conceptual framework models the patient as an active economic agent who evaluates the benefits and costs for continuing with therapy. We argue that a combination of loss aversion and mental accounting operations explains why patients discontinue with therapy at a specific point in time. We designed a randomized laboratory economic experiment with a student subject pool to investigate the behavioral predictions.ResultsSubjects continue with therapy as long as experienced utility losses have to be compensated. As soon as previous losses are evened out, subjects perceive the marginal benefit of persistence lower than in the beginning of the treatment. Consequently, subjects start to discontinue with therapy.ConclusionsOur results highlight that concepts of behavioral economics capture the dynamic structure of medical nonpersistence better than does standard economic choice theory. We recommend that behavioral economics should be a mandatory part of the development of possible intervention strategies aimed at improving patients’ compliance and persistence behavior. author: - first_name: Behnud full_name: Mir Djawadi, Behnud id: '26032' last_name: Mir Djawadi orcid: 0000-0002-6271-5912 - first_name: Rene full_name: Fahr, Rene id: '111' last_name: Fahr - first_name: Florian full_name: Turk, Florian last_name: Turk citation: ama: Mir Djawadi B, Fahr R, Turk F.
