Many experimental studies report that economics students tend to act more selfishly than students of other disciplines, a finding that received widespread public and professional attention. Two main explanations that the existing literature offers for the differences found in the behavior...

We investigate whether the concept of guilt aversion in economics is related to the psychological characterization of the same phenomenon. For trust games and dictator games we report correlations between the guilt sensitivity measured within a framework of psychological games most common in...

In experimental games, a substantial minority of players often fail to best respond. Using two-person 3x3 one-shot games, we investigated whether 'structuring' the pre-decision deliberation process produces greater consistency between individuals' stated values and beliefs on the one hand and...

When do ex-ante beliefs about the values of others affect compliance and honesty? To answer this question, we conduct an experiment, in which subjects face repeated trade-offs between monetary gain and honesty. As a source of exogenous variation, half of the subjects were told that their choices...

Since decades, cross-cultural psychology examines moral values using data from standardized surveys, assuming that values guide human behavior. We add to this literature by studying the link between moral values and various forms of prosocial behavior, using data from respondents of the sixth...

Members of various species engage in altruism — i.e. accepting personal costs to benefit others. Here we present an incentivized experiment to test for altruistic behavior among AI agents consisting of large language models developed by the private company OpenAI. Using real incentives for AI...

In recent years a large number of experimental studies have documented the existence of strong reciprocity among humans. Strong reciprocity means that people willingly repay gifts and punish the violation of cooperation and fairness norms even in anonymous one-shot encounters with genetically...

In experiments with two-person sequential games we analyze whether responses to favorable and unfavorable actions depend on the elicitation procedure. In our 'hot' treatment the second player responds to the first player's observed action while in our 'cold' treatment we follow the 'strategy...

Previous indirect evidence suggests that impulses towards pro-social behavior are diminished when an external authority is responsible for an outcome. The responsibility-alleviation effect states that a shift of responsibility to an external authority dampens internal impulses toward honesty,...

Using an economic bargaining game, we tested for the existence of two phenomena related to social norms, namely norm manipulation – the selection of an interpretation of the norm that best suits an individual – and norm evasion – the deliberate, private violation of a social norm. We found...
