Development of Household Discrete Choice Model Incorporating Multiple Decision-Marking Rules and Application to Analysis of Car Type Choice

Abstract

This paper developed a household choice model incorporating heterogeneous group decision-making rules using latent class modeling approach. In addition, the model can consider correlation between alternatives by paired combinatorial logit modeling approach. This paper deals with the following three types of household choice rules: additive, max-min and maxmax rules, and applies the model to household car type choice behavior analysis. As a result, the model with additive and max-max roles has the highest model performance, and household characteristics and life stage are important factors explaining household decision-marking rules.
