Recently a credibility crisis has taken hold across the social sciences, arguing that a component of Fischer (1935)’s tripod has not been fully embraced: replication. The importance of replications is not debatable scientifically, but researchers’ incentives are not sufficient to encourage...

We combined a natural experiment (the occurrence of the COVID-19 pandemic in 2020) with the tools of laboratory experiments to study whether and how an unprecedented shock on social interactions (the introduction and abrogation of a nationwide lockdown) affected the evolution of individuals’...

Several recent papers argue that contracts provide reference points that affect ex post behavior. We test this hypothesis in a canonical buyer-seller relationship with renegotiation. Our paper provides causal experimental evidence that an initial contract has a highly significant and...

While previous research has shown that social preferences develop in childhood, we study whether this development is accompanied by reduced use of deception when lies would harm others, and increased use of deception to benefit others. In a sample of children aged between 7 and 14, we find...

A stream of research examining the effect of punishment on conformity indicates that punishment can backfire and lead to suboptimal social outcomes. We examine whether this effect is due to a lack of perceived legitimacy of rule enforcement, enabling agents to justify selfish behavior. We...

Little is known about the underlying mechanisms of behavioral contagion, in particular with respect to differences in contagion of pro- versus anti-social behavior. Our principal contribution is the use of a novel experimental approach that enables us to analyze the contagion of behavior under...

A stream of research examining the effect of punishment on conformity indicates that punishment can backfire and lead to suboptimal social outcomes. In such studies, the enforcement of a behavioral rule to cooperate originates from a single party. This feature may raise concern about the...
