We investigated whether financial risk preferences are dependent on the financial domain (i.e., the context) in which the risky choice options are presented. Previous studies have demonstrated that risk attitudes change when gambles are framed as gains, losses, or as insurance. Our study explores this directly by offering choices between identical gambles, framed in terms of seven financial domains. Three factors were extracted, explaining 68.6% of the variance: Factor 1 (Positive)-opportunity to win, pension provision, and job salary change; Factor 2 (Positive-Complex)-investments and mortgage buying; Factor 3 (Negative)-possibility of loss and insurance. Inspection of the solution revealed context effects on risk perceptions across the seven scenarios. We also found that the commonly accepted assumption that women are more risk averse cannot be confirmed with the context structure suggested in this research; however, it is acknowledged that in the students' population the variance across genders might be considerably less. These results suggest that our financial risk attitude measures may be tapping into a stable aspect of "context dependence" of relevance to real-world decision making.
我们研究了财务风险偏好是否取决于风险选择选项呈现的金融领域(即背景)。先前的研究表明,当赌博被框定为收益、损失或保险时,风险态度会发生变化。我们的研究通过在七个金融领域提供相同赌博的选择来直接探讨这一点。提取了三个因素,解释了 68.6%的方差:因素 1(正-机会赢、养老金规定和工作工资变化);因素 2(正-复杂-投资和抵押贷款购买);因素 3(负-损失和保险的可能性)。对七种情况下风险认知的解决方案进行检查,发现了上下文效应对风险认知的影响。我们还发现,不能用本研究中提出的上下文结构来证实女性更厌恶风险的普遍假设;然而,人们承认,在学生群体中,性别差异可能会小得多。这些结果表明,我们的财务风险态度衡量标准可能反映了与现实世界决策相关的“背景依赖性”的稳定方面。
