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.
