We report results from three well-known experimental paradigms, where we use time, rather than money, as the salient component of subjects’ incentives. The three experiments, commonly employed to study social preferences, are the dictator game, the ultimatum game and the trust game. All...

This paper studies lying in a novel context. Previous work has focused on situations in which people are either fully aware of the economic consequences of all available actions (e.g., die-under-cup paradigm), or they are uncertain, but this uncertainty cannot be cleared in any way (e.g.,...

We review two fundamentally different ways that decision time is related to cooperation. First, studies have experimentally manipulated decision time to understand how cooperation is related to the use of intuition versus deliberation. Current evidence supports the claim that time pressure (and,...

Recent work using decontextualized economic games suggests that cooperation is a dynamic decision-making process: automatic responses typically support cooperation on average, while deliberation leads to increased selfishness. Here we performed two studies examining how these temporal effects...

Whether or not there are gender differences in altruistic behaviour in Dictator Game experiments has attracted considerable attention in recent years. Earlier studies found women to be more altruistic than men. However, this conclusion has been challenged by more recent accounts, which have...

This paper addresses four stylized facts that summarize data from experimental studies of voluntary contributions to provision of public goods. Theoretical propositions and testable hypotheses for voluntary contributions are derived from two models of social preferences, the inequity aversion...
