A Theory of Ex Post Rationalization

Theoretical Economics 2022-03-21 v9

Abstract

People rationalize their past choices, even those that were mistakes in hindsight. We propose a formal theory of this behavior. The theory predicts that sunk costs affect later choices. Its model primitives are identified by choice behavior and it yields tractable comparative statics.
