A Simple Model of Self‐Assessment
构建了一个简单模型，描述个体如何通过他人评价和自身经验学习自身能力，预测在不完美沟通下他人评价偏正面，且过度自信比自信不足更常见。
We develop a simple model that describes individuals' self-assessments of their abilities. We assume that individuals learn about their abilities from appraisals of others and experience. Our model predicts that if communication is imperfect, then ("i") appraisals of others tend to be too positive and ("ii") overconfidence leading to too much activism is more likely than underconfidence leading to too much passivity. The predictions of our model are consistent with findings in the social psychological literature. Copyright © The Author(s). Journal compilation © Royal Economic Society 2009.
