Abstract

The fact that any two choices are necessarily asynchronous raises the question of whether some alternative x at moment t remains the same alternative x at moment t + 1. It is argued that this question cannot be answered without taking into account the decision-maker’s perception of the choice problem. Consequently, an objective description of a choice problem is impossible for each description involves an interpretation. A definition of sameness is provided and an extension of the standard choice model is suggested. The problem of the possibility of different perceptions of the decision-maker and the observer is emphasized
