text: 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.

text: The security of Industrial Control Systems is relevant both for reliable production
system operations and for high-quality throughput in terms of manufactured products.
Security measures are designed, operated and maintained by different roles along
product and production system lifecycles. Defense-in-Depth as a paradigm builds
upon the assumption that breaches are unavoidable. The paper at hand provides
an analysis of roles, corresponding Human Factors and their relevance for data
theft and sabotage attacks. The resulting taxonomy is reflected by an example
related to Additive Manufacturing. The results assist in both designing and redesigning
Industrial Control System as part of an entire production system so that Defense-in-Depth
with regard to Human Factors is built in by design.

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: "Successful design of human-in-the-loop control sys- tems requires appropriate
models for human decision makers. Whilst most paradigms adopted in the control
systems literature hide the (limited) decision capability of humans, in behavioral
economics individual decision making and optimization processes are well-known
to be affected by perceptual and behavioral biases. Our goal is to enrich control
engineering with some insights from behavioral economics research through exposing
such biases in control-relevant settings.\r\nThis paper addresses the following
two key questions:\r\n1) How do behavioral biases affect decision making?\r\n2)
What is the role played by feedback in human-in-the-loop control systems?\r\nOur
experimental framework shows how individuals behave when faced with the task of
piloting an UAV under risk and uncertainty, paralleling a real-world decision-making
scenario. Our findings support the notion of humans in Cyberphysical Systems underlying
behavioral biases regardless of – or even because of – receiving immediate outcome
feedback. We observe substantial shares of drone controllers to act inefficiently
through either flying excessively (overconfident) or overly conservatively (underconfident).
Furthermore, we observe human-controllers to self-servingly misinterpret random
sequences through being subject to a “hot hand fallacy”. We advise control engineers
to mind the human component in order not to compromise technological accomplishments
through human issues."

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.
