Learning to Reoptimize Consumption at New Income Levels: A Rationale for Prospect Theory
为前景理论的三个实验结果（基于得失的风险偏好、损失厌恶、敏感性递减）提供了理论解释，认为有限理性的决策者在新收入水平下无法确定最优消费，从而改变间接效用函数，导致风险态度变化。
This paper provides a theoretical rationale for three experimental results of Prospect Theory: risk preferences are over gains and losses, loss aversion, and diminishing sensitivity. We consider a (boundedly rational) decision maker who does not find her new optimal consumption bundle with certainty when she is faced with a new income level. This alters her indirect utility function and makes her more risk averse at her current reference income level and less risk averse for a range of incomes below her reference income level.
