摘要

一个长期存在的难题是，过度自信是如何在以反复反馈为特征的环境中持续存在的。本文研究了多次参与高强度赛事激励系统，每次学习相对绩效的管理者。通过简化形式和结构方法，我们发现(1)管理者对未来绩效的预测过于自信;(2)管理者对过去业绩的记忆过于正面;(iii)这两种现象在个人层面上有联系。我们的研究结果与动机信念模型是一致的，在这种模型中，个体被动机扭曲对反馈的记忆，并保持不切实际的期望。(jel d82, d83, j33, l25, l81, m52, m54)

Persistent Overconfidence and Biased Memory: Evidence from Managers

A long-standing puzzle is how overconfidence can persist in settings characterized by repeated feedback. This paper studies managers who participate repeatedly in a high-powered tournament incentive system, learning relative performance each time. Using reduced form and structural methods we find that (i) managers make over-confident predictions about future performance; (ii) managers have overly positive memories of past performance; (iii) the two phenomena are linked at an individual level. Our results are consistent with models of motivated beliefs in which individuals are motivated to distort memories of feedback and preserve unrealistic expectations.
