  text: <jats:p>The aggregation of rating metrics in reputation systems is crucial
    for mitigating information overload by condensing customer rating distributions
    into singular valence scores. While platforms typically employ technical aggregation
    functions, such as the arithmetic mean to capture product quality, it remains
    unclear whether these functions align with customers' innate aggregation patterns.
    To address this knowledge gap, we designed a controlled economic decision experiment
    to elicit customers' aggregation principles by analyzing their product ranking
    decisions and contrasting these with various reference functions. Our findings
    indicate that, on average, customers aggregate rating information in accordance
    with the arithmetic mean. However, a granular analysis at the individual level
    reveals significant heterogeneity in aggregation behavior, with a substantial
    cluster exhibiting binary patterns that focus equally on negative (1-2 star) and
    positive (4-5 star) ratings. Additional clusters concentrate on negative feedback,
    particularly 1-star ratings or 1-2 star ratings collectively. Notably, these inherent
    aggregation patterns exhibit stability across variations in numerical information
    presentation and are not significantly influenced by individual characteristics,
    such as online shopping experience, risk attitudes, or demographics. These findings
    suggest that while the arithmetic mean captures average consumer behavior, platforms
    could benefit from offering customizable aggregation options to better cater to
    diverse user preferences for processing rating distributions. By doing so, platforms
    can enhance the effectiveness of their reputation systems and improve the overall
    quality of decision-making for consumers.</jats:p>

  text: <jats:p>In many Western societies, mass immigration has been one of the most
    divisive policy issues in recent years. Seemingly moderate inflows of migrants
    can have substantial demographic consequences in the long run, due to (1) higher
    fertility of the migrant population, (2) its younger age distribution, and (3)
    the possibility of family reunification. Yet, demography hardly appears in the
    policy debate, even in media outlets that are critical of mass immigration. This
    may indicate that the mechanics of population dynamics are not widely understood.
    We design a laboratory experiment in which we confront subjects with 30 different
    migration scenarios. Subjects have to decide when to stop a given inflow of migrants
    to achieve a target share of migrants after 60 years. In line with all our pre-registered
    hypotheses, in scenarios that contain elements of usual mass immigration the growth
    of the migrant population is systematically underestimated. This bias is even
    stronger in scenarios that closely resemble the German situation since the opening
    of the borders during the 2015 refugee crisis.</jats:p>

  text: <jats:sec><jats:title>Introduction</jats:title><jats:p>Human-machine interactions
    become increasingly pervasive in daily life and professional contexts, motivating
    research to examine how human behavior changes when individuals interact with
    machines rather than other humans. While most of the existing literature focused
    on human-machine interactions with algorithmic systems in advisory roles, research
    on human behavior in monitoring or verification processes that are conducted by
    automated systems remains largely absent. This is surprising given the growing
    implementation of algorithmic systems in institutions, particularly in tax enforcement
    and financial regulation, to help monitor and identify misreports, or in online
    labor platforms widely implementing algorithmic control to ensure that workers
    deliver high service quality. Our study examines how human dishonesty changes
    when verification of statements that may be untrue is performed by machines vs.
    humans, and how ambiguity in the verification process influences dishonest behavior.</jats:p></jats:sec><jats:sec><jats:title>Method</jats:title><jats:p>We
    design an incentivized laboratory experiment using a modified die-roll paradigm
    where participants privately observe a random draw and report the result, with
    higher reported numbers yielding greater monetary rewards. A probabilistic verification
    process introduces risk of identifying a lie and punishment, with treatments varying
    by verification entity (human vs. machine) and degree of ambiguity in the verification
    process (transparent vs. ambiguous).</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Our
    results show that under transparent verification rules, cheating magnitude does
    not significantly differ between human and machine auditors. However, under ambiguous
    conditions, cheating magnitude is significantly higher when machines verify participants'
    reports, reducing the prevalence of partial cheating while leading to behavioral
    polarization manifested as either complete honesty or maximal overreporting. The
    same applies when comparing reports to a machine entity under ambiguous and transparent
    verification rules.</jats:p></jats:sec><jats:sec><jats:title>Discussion</jats:title><jats:p>These
    findings emphasize the behavioral implications of algorithmic opacity in verification
    contexts. While machines can serve as effective auditors under transparent conditions,
    their black box nature combined with ambiguous verification processes may unintentionally
    incentivize more severe dishonesty. These insights have practical implications
    for designing automated oversight systems in tax audits, compliance, and workplace
    monitoring.</jats:p></jats:sec>

  text: 'Normative expectations – beliefs about what others perceive as appropriate
    – have been shown to influence behavioural choices across various domains. 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. '

  text: 'Social norms fundamentally shape economic decision-making, yet individuals
    often systematically misperceive what others think and do, potentially leading
    to suboptimal social outcomes. We examine how such misperceptions affect behaviour
    and whether correcting them can induce a behavioural change, using whistleblowing
    as an application. Through survey data and an incentivized laboratory experiment,
    we demonstrate that while a majority of individuals (>75%) privately support whistleblowing,
    almost half (45.92%) misperceive the majority’s view. Both personal normative
    beliefs and normative expectations strongly predict whistleblowing behaviour.
    Their alignment is particularly noteworthy: individuals who personally support
    whistleblowing are more likely to report misconduct when they believe others share
    their views. A social information intervention revealing the true distribution
    of peer support affects subgroups differently: while it increases whistleblowing
    behaviour among individuals who already personally favour reporting misconduct,
    there is no effect among those who are personally resistant to it. Still, given
    the relatively low cost of such social information interventions, they offer an
    economically viable means of achieving behavioural change in at least some of
    the targeted individuals. '

  text: Aggregation metrics in reputation systems are important for overcoming information
    overload. 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.

  text: "Models on network formation have often been extended to include the potential
    of network disruption in recent years. 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)."

  text: "In Internet transactions, customers and service providers often interact
    once and anonymously.\r\nTo prevent deceptive behavior a reputation system is
    particularly important to\r\nreduce information asymmetries about the quality
    of the offered product or service. 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."

  text: 'We investigate the pervasiveness of lying in professional contexts such as
    insurance fraud, tax evasion and untrue job applications. 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.'

  text: BackgroundMedical nonpersistence is a worldwide problem of striking magnitude.
    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.
