Die Pandemie verdeutlicht manche Schwächen menschlicher Rationalität, auf die die Verhaltensökonomie hinweist. Aber auch die Verhaltensökonomie selbst sollte aus der Krise lernen. Sie muss die Grenzen des von ihr propagierten Altruismus neu ausloten und das Verhältnis von Generosität im...

Increasing inequality and associated egalitarian sentiments have again put redistribution on the political agenda. Support for redistribution may also be affected by altruistic and egalitarian preferences, but knowledge about the distribution of these preferences in the broader population and...

Building on the epidemiological SIR model we present an economic model with heterogeneous individuals deriving utility from social contacts creating infection risks. Focusing on social distancing of individuals susceptible to an infection we theoretically analyze the gap between private and...

We study physician agency and optimal payment policy in the context of an expensive medication used in dialysis care. Using Medicare claims data we estimate a structural model of treatment decisions, in which physicians differ in their altruism and marginal costs, and this heterogeneity is...

In this paper, we first provide a brief exposition of the simplest version of the selfish life cycle model or hypothesis, which is undoubtedly the most widely used theoretical model of household behavior in economics, and then survey the literature on household saving behavior in Japan (with...

Do rising inequality and youth unemployment aect preferences for redistribution? Using country-level European survey data from 2002 to 2015, I show that changes in market inequality and the rise of (youth) unemployment increase preferences for redistribution. The ndings are supported by the...

The literature suggests that the household invests in the human capital of a child member not only for altruistic reasons but also as insurance against future income shocks. Hence, the allocation of the child's time between school and work is a function of the risk preference of the household...

We conduct an experiment where subjects are matched in groups of three and vote on a moral transgression. Analyzing different voting rules, the frequency of votes for the moral transgression increases with the number of votes required for it. This effect persists when considering pivotal votes...

Do people conform to social norms at least partly to signal their social preferences? Using a vignette experiment, we find that parents who do not marry off their under-age daughters in Malawian villages where child marriage is prevalent are perceived as less altruistic, reciprocal, and...

Two important aspects of global environmental problems are that (1) the actions of past generations affect the opportunities of the present, and (2) both in the past and the present generations, collaboration across different countries is needed to provide global public goods. In this paper, we...

Indirect reciprocity is defined as a specific kind of behavior: An agent rewards or penalizes another agent for having behaved kindly or unkindly toward a third party. This paper analyzes the question of what drives indirect reciprocity: Does the agent reward or penalize because she...

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...

We investigate the quality provision behavior and its implications for the occurrence of collusion in competitive health care markets where providers are assumed to be altruistic towards patients. For this, we employ a laboratory experiment with a health care market framing where subjects decide...

Decisions with long-term consequences require comparing utility derived from present consumption to future welfare. But can we infer socially relevant intertemporal preferences from saving behavior? I allow for a decomposition of the present generation's preference for the next generation into...

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...

Mutation-generated variation in behavior is thought to promote the evolution of cooperation. Here, we study this by distinguishing two effects of mutation in evolutionary games of the finitely repeated Prisoner’s Dilemma in infinite asexual populations. First, we show how cooperation can...

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...

We study the interaction between competition and social proximity on altruism, trust, and reciprocity. We decompose the behavioral channels by utilizing variants of both the Trust Game and the Dictator Game in a design that systematically controls the transmission of relevant information. Our...

Our thesis is that the reason many of us today are inclined toward socialism (explicit cooperation) and against laissez-faire capitalism (implicit cooperation) is because the first type of behavior was much more genetically beneficial during previous generations of our species. There is,...

This study examines the relationship between the access to homebuyer credits and housing satisfaction among those buying affordable apartments, using a sample of 1,000 respondents from our own survey in 2016 in Hanoi, Da Nang and Ho Chi Minh Cities. Our regression analysis reveals the education...

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...

This paper explores inequalities in IQ and economic preferences between children from high and low socio-economic status (SES) families. We document that children from high SES families are more intelligent, patient and altruistic, as well as less risk-seeking. To understand the underlying...

Charitable donations provide positive externalities and can potentially be increased with an understanding of donor preferences. We obtain a uniquely comprehensive characterization of donation motives using an experiment that varies treatments between and within subject. Donations are increasing...

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...

Parenting decisions are among the most consequential choices people make throughout their lives. Starting with the work of pioneers such as Gary Becker, economists have used the toolset of their discipline to understand what parents do and how parents' actions affect their children. In recent...

We present controlled experimental evidence on how rent extraction by an administrator affects giving to non-profit associations. Holding the price of giving constant, we compare contributions between two conditions: a rent extraction condition, in which an administrator can expropriate a part...

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. Our study questions the universality of these claims. We employ a novel four-party setup to disentangle the roles that...

A growing body of research has been investigating the role of management practices and managerial behaviour in conventional private firms and public sector organizations. However, little is known about managers' behavioural profile in noninvestor-owned firms. This paper aims to fill this gap by...

We investigate the presence and stability of dynamically inconsistent time preferences across contexts with and without interpersonal trade-offs. In a longitudinal experiment subjects make a series of intertemporal allocation decisions of real-effort tasks between themselves and another person....

This study investigates the role of owners' personal preferences and behaviour in determining the success of micro, small and medium-sized enterprises using a lab-in-the-field experiment with small-business owners in Myanmar. The study is a complement to a 2017 quantitative survey conducted...

Can social norms affect fundamental patterns of behavior such as income effects? Studies of determinants of giving to charities and other individuals yield a wide range of income-effect estimates. We conduct two experiments to first test whether the effect of income on charitable giving depends...

Empirical evidence suggests that charitable contributions to public goods by businesses may be driven not only by the familiar warm-glow of giving motive but also as a means for businesses to signal high product quality. Building on this finding, we present an analytical framework that...

We study spatially differentiated competition between charities by partnering with two foodbanks in two neighboring cities to conduct a field experiment with roughly 350 donation appeals. We induce spatial differentiation by varying the observability of charities' location such that each donor...

An often-replicated result in the experimental literature on social dilemmas is that a large share of subjects reveal conditionally cooperative preferences. Cooperation generated by this type of preferences is notoriously unstable, as individuals reduce their contributions to the public good in...
