This study tests some of its design features to determine whether\r\nelicited beliefs and related behaviours vary depending on i) the time of elicitation (before vs after the\r\ndecision), ii) incentivizing vs not incentivizing a question about normative expectations, and iii)\r\nquestioning subjects on their beliefs about the action of interest alone or combined with an alternative\r\naction. An online experiment is conducted via Prolific comprising a dictator game and the elicitation of\r\nfairness beliefs. A pretest reveals that applying role uncertainty does not alter beliefs and behaviours\r\ncompared to a baseline treatment without it. Subsequently, three treatments are implemented. Contrary\r\nto previous studies, results indicate that varying the time of elicitation does not significantly alter the\r\nmoney-share decision. However, incentivizing the question about normative expectations significantly\r\nincreases the fit with the actual majority norm. Finally, asking about a fair share and an unfair share\r\ninstead of only about fair sharing does not alter personal normative beliefs or normative expectations,\r\nbut it increases the empirical expectations that other dictators have provided a fair share." author: - first_name: Sabrina full_name: Plaß, Sabrina id: '34502' last_name: Plaß citation: ama: Plaß S.

How to meet this need is an open question, but “behavioral insights” are likely components of future policy designs. Applying well-established behavioral insights to low-income house- holds raises questions of transportability as they are typically underrepresented in the existing evidence base. We illustrate this problem by conducting a randomized field experiment on scalable, low-cost design elements to improve program take-up in one of the world’s largest en- ergy efficiency assistance programs. Observing investment decisions of over 1,800 low-income households in Germany’s “Refrigerator Replacement Program”, we find that the transportabil- ity problem is real and consequential: First, the most effective policy design would not have been chosen based on existing behavioral insights. Second, design elements favored by these insights either prove ineffective or even backfire, violating ‘do no harm’ principles of policy advice. Systematic testing remains crucial for addressing the transportability problem, partic- ularly for policies targeting vulnerable groups.\r\n" author: - first_name: Martin full_name: Kesternich, Martin id: '98922' last_name: Kesternich orcid: 0000-0002-0653-7680 - first_name: Bettina full_name: Chlond , Bettina last_name: 'Chlond ' - first_name: 'Timo ' full_name: 'Goeschl, Timo ' last_name: Goeschl - first_name: Madeline full_name: Werthschulte, Madeline last_name: Werthschulte citation: ama: 'Kesternich M, Chlond B, Goeschl T, Werthschulte M.

We examine this concept in the context of whistleblowing, where potential whistleblowers face two competing norms: promoting fairness by reporting wrongdoing versus maintaining loyalty to peers by staying silent. We investigate how normative expectations about these two mutually exclusive actions affect reporting decisions. Specifically, we test whether providing information on the majority beliefs about either the appropriateness of whistleblowing, or of staying silent, or about both behaviours together, differentially affects the whistleblowing decision. Using an incentivized experiment with UK employees on Prolific, our study yields four key findings: First, employees are more likely to report misconduct when they believe that the majority considers whistleblowing to be appropriate. Second, they are less likely to blow the whistle when they believe staying silent is deemed appropriate. Third, this effect prevails for a particularly important subgroup: among employees who believe that the majority supports whistleblowing, the reporting probability increases substantially when they simultaneously expect that staying silent is deemed inappropriate. Fourth, providing information about both normative dimensions combined or only about the inappropriateness of staying silent significantly increases whistleblowing compared to the (no information) baseline and to information about whistleblowing appropriateness alone. These findings demonstrate the importance of normative expectations about both behavioural options for accurately predicting whistleblowing behaviour, and that social information interventions are most effective when they target behaviours where appropriateness beliefs about conflicting options are dispersed.

The ratchet-up mechanism prescribes that parties’ commitments to the global response to climate change cannot decrease over time, and our results show that its effect is detrimental. We design a public goods game to study whether cooperation is promoted by an amendment to the mechanism that stipulates that all agents must contribute at least a collectively chosen minimum based on the principle of the lowest common denominator. We find that binding collective minimum contributions improve the effectiveness of the ratchet-up mechanism. Non-binding minimum contributions, by contrast, do not encourage cooperation. Our data indicate that the difference is attributable to conditional cooperative dynamics. If other participants contribute less than the collective minimum contribution, even initially cooperative participants start to negatively reciprocate this form of non-compliance by contributing less. author: - first_name: Marius full_name: Alt, Marius last_name: Alt - first_name: Martin full_name: Kesternich, Martin id: '98922' last_name: Kesternich - first_name: Carlo full_name: Gallier, Carlo last_name: Gallier - first_name: Bodo full_name: Sturm, Bodo last_name: Sturm citation: ama: Alt M, Kesternich M, Gallier C, Sturm B.

Students often demonstrate limited ability to link these different levels. Augmented reality (AR) offers the possibility to increase contiguity by embedding virtual models into hands-on experiments. Therefore, this paper presents a pre- and post-test study investigating how learning and cognitive load are influenced by AR during hands-on experiments. Three comparison groups (AR, animation and filmstrip), with a total of N = 104 German secondary school students, conducted and explained two hands-on experiments. Whereas the AR group was allowed to use an AR app showing virtual models of the processes on the submicroscopic level during the experiments, the two other groups were provided with the same dynamic or static models after experimenting. Results indicate no significant learning gain for the AR group in contrast to the two other groups. The perceived intrinsic cognitive load was higher for the AR group in both experiments as well as the extraneous load in the second experiment. It can be concluded that AR could not unleash its theoretically derived potential in the present study. article_number: '9' author: - first_name: Hendrik full_name: Peeters, Hendrik id: '49942' last_name: Peeters orcid: https://orcid.org/ 0000-0002-7143-3781 - first_name: Sebastian full_name: Habig, Sebastian last_name: Habig - first_name: Sabine full_name: Fechner, Sabine id: '54823' last_name: Fechner orcid: 0000-0001-5645-5870 citation: ama: Peeters H, Habig S, Fechner S.

Despite a wide-ranging debate on the use of learning objectives, empirical research on their effectiveness is scarce. The present study uses the features of digital teaching platforms to investigate the perception and effectiveness of learning objectives applying a randomised controlled experiment followed by a survey in a course for undergraduate economics students (N = 30). Controlling group preconditions and the treatment effect allows to draw conclusions about the different learning outcomes of the student groups. The specification of behaviour-oriented learning objectives in the online course system leads to significantly better performance in the treatment group. A stronger perception of the learning objectives in the treatment group supports this effect that remains significant in a regression analysis. Thus, the study provides an empirical justification to integrate learning objectives in university teaching." article_type: original author: - first_name: Thorsten Fabian full_name: Auer, Thorsten Fabian id: '49071' last_name: Auer citation: ama: Auer TF.

Following the steadily growing interest in business model innovation, software tools have shown great potential in supporting business model development and innovation. Yet, understanding the cognitive processes involved in the generation of business model ideas is an aspect of software design-knowledge that has so far been neglected. To investigate whether providing stimuli – in this case, brainstorming questions – can enhance individual creativity in this context, we conduct an exploratory experiment with over 100 participants. Our study is the first to systematically investigate the process of idea generation using a software-based business model development tool with stimuli. Our preliminary findings have the potential to support the future development of business model development tools and to refine the research design used to evaluate such tools. accept: '1' author: - first_name: Daniel full_name: Szopinski, Daniel id: '36372' last_name: Szopinski citation: ama: 'Szopinski D.
