Self‐Fulfilling Mistakes: Characterisation and Welfare
将自我实现的错误纳入经典决策框架，用Sen公理α和γ刻画行为主体的选择数据，并提供一个福利基准来判断错误选择。
This article incorporates self‐fulfilling mistakes into an otherwise classical decision‐making framework. A behavioural agent makes a mistake when he fails to internalise all the consequences of his actions on himself. We show that Sen’s axioms α and γ fully characterise choice data consistent with behavioural agents. These two axioms are weaker than Sen’s axioms α and β that fully characterise rational agents. We offer a welfare benchmark that can be applied to existing behavioural economics models and show the conditions under which our welfare ranking can be used to infer welfare dominated (i.e. mistaken) choices using choice data alone.
