本文报告了两种主要的个人风险态度测量方法-Holt和Laury（2002）彩票选择任务和Dohmen等人（2011）倡导的多项目问卷-随时间推移的受试者内稳定性的实证比较（一年）以及它们与实验室中实际冒险行为的相关性-这里是信任游戏中发送的金额（贝格等人，1995年）。我们的研究结果表明，这两个风险态度的措施，充其量只有弱相关。只有问卷测量显示出高的重测稳定性，而几乎没有这样的稳定性被发现在彩票选择任务。此外，只有问卷测量显示了与大五人格测量的预期相关性，并与实际的冒险行为相关。对于信任博弈中的行为，我们发现转移具有较高的重测稳定性。这支持了这样一个猜想，即信任行为有一个组成部分，它本身就是一个稳定的个人特征。
This paper reports on an empirical comparison of two prominent measures of individual risk attitudes – the Holt and Laury (2002) lottery-choice task and the multi-item questionnaire advocated by Dohmen et al. (2011) – with respect to their within-subject stability over time (one year) and their correlation with actual risk-taking behavior in the lab – here the amount sent in a trust game (Berg et al., 1995). Our results suggest that the two risk attitude measures are at best only weakly correlated. Only the questionnaire measure shows high test–retest stability, while virtually no such stability is found in the lottery-choice task. In addition, only the questionnaire measure shows the expected correlations with a Big Five personality measure and is correlated with actual risk-taking behavior. With respect to behavior in the trust game, we find a high retest stability of transfers. This supports the conjecture that trusting behavior has a component which itself is a stable individual characteristic.
