 Bicchieri and Chavez (2010) designed an experiment to investigate norm compliance in ultimatum games. Specifically, their experiment involved a variant of the ultimatum game whereby the proposer could choose one of the following three options: ($5, $5), ($8, $2), or Coin (in which case one of the other two allocations would be selected at random). This design allows for two plausible notions of fairness: as an equal outcome ($5, $5) or as a fair procedure (Coin). The experimenters elicited subjects’ normative expectations about the actions they thought would be considered fair by most participants: proposers and responders showed a remarkable degree of agreement in their notions of fairness, as most subjects believed that a majority of participants deemed both ($5, $5) and Coin to be appropriate. Further, the experimenters had subjects play three instances of the above ultimatum game under different information conditions. In the “full information” condition, all participants knew that the Coin option was available, and that responders would know if their respective proposer had chosen Coin. In the “private information” condition, responders did not know that Coin was available to proposers, and proposers were aware of responders’ ignorance. In the “limited information” condition, participants knew that the Coin option was available, but responders would not be able to distinguish whether their respective proposer had implemented one of the two allocations directly or had chosen Coin instead. The experimental results show that when normative expectations supporting the Coin option were either absent (in the private condition) or could be defied without consequence (in the limited condition), the frequency of choice of ($5, $5) and ($8, $2), respectively, were considerably higher than those of Coin. Moreover, the frequency of Coin choices was highest in the public information condition, where such option was common knowledge and its outcome transparent: this shows that there proposers followed the rule of behavior that favored them most, and that such a rule was effectively a social norm. On the other hand, substantial norm evasion characterized proposers’ behavior in the limited information condition, where ($8, $2) was the most frequent choice.
