Proposal for reformulation of behavioral economic concepts centered on intangible goods by quantum information theory: Feasibility of mathematical design of customer experience

Abstract

The purpose of this study is to explore whether it is possible to construct an economic model from the viewpoint of Theory of measurement, which is a constitutive principle of quantum information theory, the fundamental theory of quantum computers. I proposed a model for quantifying customer satisfaction with intangible goods, where the issue is uncertainty due to the subjectivity of customer evaluations. From the entropy obtained from this economic model, a nonlinear asymmetric value function was derived. The value function of subjective well-being, which is a general value function encompassing the nonlinear asymmetric value function, can be explained by treating the customer’s experience of intangible goods as a rotation in Hilbert space, which leads to a violation of the independence axiom that cannot be described by classical probability theory due to phase interference, and applying the results to behavioral economics. The results are explained by applying them to behavioral economics results. This has provided new insights into the structure of subjective evaluation of the experience of intangible goods, and has increased the feasibility of constructing an economic model based on quantum information theory and the feasibility of mathematical design of customer experience.
