Does time heal all wounds? Psychological responses to trauma and financial risk‐taking
研究创伤后应激障碍症状与个人金融风险承担行为的关系，发现中等症状者更可能投资风险资产，而高症状者则更保守，且这种关联通过偏好而非信念渠道起作用。
Abstract We study whether psychological responses to trauma are associated with financial risk‐taking behavior. Posttraumatic stress disorder (PTSD) symptoms for individuals, assessed after the traumatic experiences, are used as psychological responses to the events. Individuals who experience moderate‐level PTSD symptoms are 1.5% more likely to invest in risky assets, whereas individuals with high‐level PTSD symptoms are 2.4% less likely to invest in risky assets. Further analysis suggests that the association between PTSD symptoms and risk‐taking comes through a preferences channel rather than a beliefs channel.
