Journal Article

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...

Who discriminates? Evidence from a trust game experiment across three societies (2023)
Journal Article

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?

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

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?

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)
Journal Article

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.

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

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’).
