短视损失规避(MLA)是指如果投资者频繁地评估其投资回报,那么他在投资时就会减少对风险资产的投入。本文采用实验法探讨了任务概率水平与模糊性对MLA的影响。结果 MLA只存在于中等损失概率中,说明该现象并非普遍存在。一旦概率变得模糊,在高损失概率任务中会出现MLA,而在低损失概率任务中则出现反向的MLA,说明模糊性能扩展“短视”起作用的概率范围。
Short-hacking Losses Avoidance (MLA) means that if an investor evaluates his return on investment frequently, he or she will reduce its investment in risky assets when investing. In this paper, the influence of mission probabilities and fuzziness on MLA is discussed by means of experiments. Results MLA exists only in the probability of moderate loss, indicating that the phenomenon is not ubiquitous. Once the probability becomes fuzzy, MLA appears in the task with high probability of loss, while in the task with low probability of loss, the opposite MLA appears, which indicates the range of probability that fuzzy performance will be extended.
