Neid, Völlerei, Habgier, Wollust, Hochmut, Trägheit und Zorn - die sogenannten sieben Todsünden sind weitgehend bekannt und noch weiter verbreitet. Sie beschreiben sieben Motive und Verhaltensweisen, die viele Menschen im Alltag begleiten, aber zugleich als Vergehen moralisch gebrandmarkt...

While it is well established that individuals and groups make different economic decisions, the reasons for the behavioral differences are still not fully understood. We experimentally compare individual and group behavior in a competitive setting where cheating can be used to outperform the...

We experimentally investigate whether individuals strategically distort their beliefs about dominant norms. Embedded in the context of lying, we systematically vary both the nature of elicited beliefs (descriptive about what others do, or normative about what others approve of) and whether...

Both theory and recent empirical evidence on nudging suggest that observability of behavior acts as an instrument for promoting (discouraging) pro-social (anti-social) behavior. We connect three streams of literature (nudging, social preferences, and social norms) to investigate the universality...

This paper studies, theoretically and experimentally, whether the entitlement effect created by deservingness affects the willingness to lie. In a laboratory experiment, we compare the lying behavior of high-endowment participants with low-endowment participants. In one treatment, the allocation...

Welche Bedeutung hat eine Lockerung der Kontaktbeschränkungen für die Erholung der deutschen Wirtschaft, und welche Schlussfolgerungen für das angemessene Niveau der Kontaktbeschränkungen sind in den kommenden Monaten zu ziehen? Um diese Fragen zu beantworten, wird abgeschätzt, welche...

Bei der Bewertung von Maßnahmen zur Eindämmung der Corona-Pandemie muss zwingend zwischen Korrelation und Kausalität unterschieden werden. Ein simpler Abgleich des zeitlichen Verlaufs der Neuinfektionen mit dem zeitlichen Verlauf der Abwehrmaßnahmen ist unzureichend: Menschen passen in der...

Is punishment of free riders driven by descriptive social norms of cooperation and punishment? We conduct experiments in which participants interact in a one-shot social dilemma with punishment. We study how punishment of free riders is influenced by behavior among members of a payoff-irrelevant...

Nicht nur aus gesundheitspolitischer Perspektive, sondern auch aus ökonomischer Sicht sollte die Lockerung der Anfang April 2020 in Deutschland existierenden Kontaktbeschränkungen zur Eindämmung der Covid-19-Pandemie auf keinen Fall übereilt erfolgen, sondern in gut vorbereiteten Schritten....

The perception of risk affects how people behave during crises. We conduct a series of experiments to explore how people form COVID-19 mortality risk beliefs and the implications for prosocial behavior. We first document that people overestimate their own risk and that of young people, while...

We investigate the causal impact of public discourse on socially responsible market behavior. We conduct laboratory market experiments with products that differ in their production costs and social impact, and provide market actors and impacted third parties with the opportunity to discuss...

This dissertation presents three independent essays that elicit social preferences in school children by using a combination of experimental measures and survey data. Chapter 2 consider the development of motivations for helping in informal risk-sharing networks from a sample of school children...

Hierarchies in social identities have been found to be integrally related to divergences in economic status. In India, caste is one such significant social identity where continued discriminatory practices towards the lower castes have resulted in poor outcomes for them. While there is...

We investigate the influence of self and social image concerns as potential sources of lying costs. In a standard die-rolling experiment, we exogenously manipulate self-awareness and observability, which mediate the focus of a person on their private and public selves, respectively. First, we...

In our laboratory experiment, subjects, in sequence, have to predict the value of a good. The second subject in the sequence makes his prediction twice: first ("first belief"), after he observes his predecessor's prediction; second ("posterior belief"), after he observes his private signal. We...

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disavantaged children aged 12 to 24 months at baseline. We estimate the determinants of parents' material and time...

I present a novel experimental design to measure lying and mistrust as continuous variables on an individual level. My experiment is a sender-receiver game framed as an investment game. It features two players: firstly, an advisor with complete information (i.e., the sender) who is incentivized...

A landmark study published in PNAS (Côté S, House J, Willer R, 2015, 112:15838–15843, doi:10.1073/pnas.1511536112) showed that higher income individuals are less generous than poorer individuals only if they reside in a U.S. state with comparatively large economic inequality. This finding...

The mission of a job does not only affect the type of worker attracted to an organisation, but may also provide incentives to an existing workforce. We conducted a natural field experiment with 267 short-time workers and randomly allocated them to either a prosocial or a commercial job. Our data...

In this work, we explore the role of learning dynamics and social norms in human cooperation on networks. We study the model recently introduced in [Physical Review E, 97, 042321 (2018)] that integrates the well-studied Experience Weighted Attraction learning model with some features...

There is a large body of evidence showing that a substantial proportion of people cooperate in public goods games, even if the situation is one-shot and completely anonymous. In the present study, we bring together two major endogenous factors that are known to affect cooperation levels, and in...

A large body of evidence shows that social identity affects behavior. However, our understanding of the substantial variation of these behavioral effects is still limited. We use a novel laboratory experiment to measure differences in preferences for social identities as a potential source of...

There is a longstanding concern that material rewards might undermine pro-social motivations, thereby leading to a decrease in blood donations. This paper provides an empirical test of how material rewards affect blood donations in a three-month large-scale field experiment and a fifteen-month...

This study shows that different belief concepts within the same religion can have different effects on distributive behaviour. A dictator game experiment measures the causal effects of the concepts of God and Jesus on both the prosociality of Christians and their propensity to discriminate...

Many modern organisations collect data on individuals' personality traits as part of their human resource selection processes. We test experimentally whether revealing information on personality data impacts on pro-social behaviour as measured in a one-shot modified dictator game and a public...

Private information is at the heart of many economic activities. For decades, economists have assumed that individuals are willing to misreport private information if this maximizes their material payoff. We combine data from 90 experimental studies in economics, psychology and sociology, and...

This paper studies individual truth-telling behavior in the presence of multiple lying opportunities with heterogeneous stake sizes. The results show that individuals lie downwards (i.e. forgo money due to their lie) in low-stakes situations in order to signal honesty, and thereby mitigate the...

Incorporating the understandings from affect theory of social exchange and rejection sensitivity theory, this study investigates relationship between rejection sensitivity and job performance. This study investigates how rejection sensitivity (RS) reducesjob performance (JP) by acknowledging...

This article studies whether people want to control which information on their own past pro-social behavior is revealed to other people. Participants in an experiment are assigned a color which depends on their own past pro-sociality. They can then spend money to increase or decrease the...

Economic inequality may fuel frustration, possibly leading to anger and antisocial behavior. We experimentally study a situation where only the rich can reduce inequality while the poor can express their discontent by destroying the wealth of a rich counterpart with whom they had no previous...

This paper focuses on belief distortion in the context of lying decisions. We employ a twostage variant of the "dice under the cup" paradigm, in which subjects' beliefs are elicited in stage 1 before performing the dice task in stage 2. In stage 1, we elicit the subjects' beliefs about (i)...

We propose a new family of mechanisms, whereby players may give more or less directly to one another. A cornerstone case is the regular linear public goods mechanism (LPGM), where all contribute into a single common group account, the total amount of which is then distributed equally among...

Economic inequality may fuel frustration, possibly leading to anger and antisocial behavior. We experimentally study a situation where only the rich can reduce inequality while the poor can express their discontent by destroying the wealth of a rich counterpart with whom they had no previous...
