We examine the role of cooperative preferences, beliefs, and punishments to uncover potential cross-societal differences in voluntary cooperation. Using one-shot public goods experiments in four comparable subject pools from the US and the UK (two si...

What personal characteristics are associated with the extent to which individuals discriminate against particular groups? We use an incentive-compatible measure of an individual's tendency to discriminate on others’ different social identities that t... Read More about Who discriminates? Evidence from a trust game experiment across three societies.

Measuring “Group Cohesion” to Reveal the Power of Social Relationships in Team Production (2023)
Journal Article

We introduce "group cohesion" to study the economic relevance of social relationships in team production. We operationalize measurement of group cohesion, adapting the "oneness scale" from psychology. A series of experiments, including a pre-register...

Preferences and Perceptions in Provision and Maintenance Public Goods (2022)
Journal Article

We study two generic versions of public goods problems: in Provision problems, the public good does not exist initially and needs to be provided; in Maintenance problems, the public good already exists and needs to be maintained. In four lab and onli... Read More about Preferences and Perceptions in Provision and Maintenance Public Goods.

Social closeness can help, harm and be irrelevant in solving pure coordination problems (2022)
Journal Article
Gächter, S., Starmer, C., Thöni, C., Tufano, F., & Weber, T. O. (2022). Social closeness can help, harm and be irrelevant in solving pure coordination problems. Economics Letters, 216, Article 110552. https://doi.org/10.1016/j.econlet.2022.110552

Experimental research has shown that ordinary people often perform remarkably well in solving coordination games that involve no conflicts of interest. While most experiments in the past studied such coordination games among socially distant anonymou...

Peer observation can influence social norm perceptions as well as behavior in various moral domains, but is the tendency to be influenced by and conform with peers domain-general? In an online experiment (N = 815), we studied peer effects in honesty... Read More about Conforming with peers in honesty and cooperation.

Social proximity and the erosion of norm compliance (2021)
Journal Article

We study how compliance with norms of pro-social behavior is influenced by peers' compliance in a dynamic and non-strategic experimental setting. We show that social proximity among peers is a crucial determinant of the effect. Without social proximi... Read More about Social proximity and the erosion of norm compliance.

Individual-level loss aversion in riskless and risky choices (2021)

Loss aversion can occur in riskless and risky choices. We present novel evidence on both in a non-student sample (660 randomly selected customers of a car manufacturer). We measure loss aversion in riskless choice in endowment effect experiments with... Read More about Individual-level loss aversion in riskless and risky choices.

Social mindfulness and prosociality vary across the globe (2021)
Journal Article

Humans are social animals, but not everyone will be mindful of others to the same extent. Individual differences have been found, but would social mindfulness also be shaped by one’s location in the world? Expecting cross-national differences to exis...

Contextualised strong reciprocity explains selfless cooperation despite selfish intuitions and weak social heuristics (2021)
Journal Article

Humans frequently cooperate for collective benefit, even in one-shot social dilemmas. This provides a challenge for theories of cooperation. Two views focus on intuitions but offer conflicting explanations. The Social Heuristics Hypothesis argues tha...

Moderating Loss Aversion: Loss Aversion Has Moderators, But Reports of its Death are Greatly Exaggerated (2019)
Journal Article

Loss aversion, the principle that losses impact decision making more than equivalent gains, is a fundamental idea in consumer behavior and decision making, though its existence has recently been called into question. Across five unique samples (Ntota... Read More about Moderating Loss Aversion: Loss Aversion Has Moderators, But Reports of its Death are Greatly Exaggerated.

People prefer coordinated punishment in cooperative interactions (2019)
Journal Article

Human groups can often maintain high levels of cooperation despite the threat of exploitation by individuals who reap the benefits of cooperation without contributing to its costs1,2,3,4. Prominent theoretical models suggest that cooperation is parti... Read More about People prefer coordinated punishment in cooperative interactions.

Leaders as role models and ‘belief managers’ in social dilemmas (2018)
Journal Article

We investigate the link between leadership, beliefs and pro-social behavior in social dilemmas. This link is interesting because field evidence suggests that people's behavior in domains like charitable giving, tax evasion, corporate culture and corr...

Dispositional free riders do not free ride on punishment (2018)
Journal Article
Weber, T. O., Weisel, O., & Gächter, S. (2018). Dispositional free riders do not free ride on punishment. Nature Communications, 9(1), Article 2390. https://doi.org/10.1038/s41467-018-04775-8

Strong reciprocity explains prosocial cooperation by the presence of individuals who incur costs to help those who helped them (‘strong positive reciprocity’) and to punish those who wronged them (‘strong negative reciprocity’). Theories of social pr... Read More about Dispositional free riders do not free ride on punishment.

Societal background influences social learning in cooperative decision making (2018)
Journal Article

Humans owe their ecological success to their great capacities for social learning and cooperation: learning from others helps individuals adjust to their environment and can promote cooperation in groups. Classic and recent studies indicate that the... Read More about Societal background influences social learning in cooperative decision making.

Social cooperation often requires collectively beneficial but individually costly restraint to maintain a public good, or it needs costly generosity to create one. Status quo effects predict that maintaining a public good is easier than providing a n... Read More about Reciprocity and the tragedies of maintaining and providing the commons.
