摘要我们研究了在两种常见的风险态度诱导任务中，提供预期彩票结果对实验参与者的影响。在一个受试者间的设计，无论是霍尔特和劳里任务或埃克尔和格罗斯曼任务进行的样本208名学生。我们没有发现显着的影响所示的期望值的风险态度测量的任务。如果我们将实验参与者分为特定的子组，即女性和男性，或较低的计算能力和较高的计算能力参与者，这个结果甚至成立。此外，理解和处理时间没有显着影响所提出的期望值。因此，我们得出的结论是，提供有关期望值的信息不会影响涉及风险的任务的决策。这一结果表明，在常见的实验方法的变化引起的风险态度的鲁棒性，并表明，可以提供更多的信息，而不会产生偏见的结果。
Abstract We investigate the influence of providing expected lottery results to experiment participants in two common risk attitude elicitation tasks. In a between-subject design, either the Holt and Laury task or the Eckel and Grossman task is carried out by a sample of 208 students. We find no significant effect of shown expected values on the risk attitude measured by the tasks. This result even holds true if we divide the experiment participants into specific sub-groups, i.e. female and male, or lower numeracy and higher numeracy participants. Furthermore, comprehension and processing time are not significantly influenced by presented expected values. Therefore, we conclude that providing information on expected values does not influence decision-making in tasks involving risk. This result indicates the robustness of elicited risk attitudes to variation in common experimental methods, and demonstrates that more information could be provided without creating bias in the results.
