On the stability of risk preferences: Measurement matters
利用四国学生重复调查实验，发现疫情期间自评风险意愿下降，但激励性彩票任务中的风险意愿上升，表明风险偏好具有领域特异性且测量方式影响结论。
We exploit the unique design of a repeated survey experiment among students in four countries to explore the stability of risk preferences in the context of the COVID-19 pandemic. Relative to a baseline before the pandemic, we find that self-assessed willingness to take risks decreased while the willingness to take risks in an incentivized lottery task increased, for the same sample of respondents. These findings suggest domain specificity of preferences that is partly reflected in the different measures.
