Title: Comparison of Regret Minimization and Utility Maximization in the Context of Travel Mode Choices
Abstract: This paper provides an empirical comparison between regret-minimization and utility-maximization perspectives on travel choice behavior. The key difference between these two perspectives is that regret-minimization implies that the anticipated satisfaction associated with a chosen alternative depends on the anticipated performance of non-chosen alternatives as well. In order to provide a meaningful statistical comparison, the paper will formulate a model of regret-minimization such that it reduces to utility-maximization for a given parameter restriction. Estimation results, based on a binary stated mode experiment, clearly show how the regret-based model outperforms its utilitarian counterpart. Furthermore it is shown how participants of the experiment attached relatively much weight to the situation where the non-chosen alternative is slightly better than the chosen one, and they tend to discount larger differences. The paper will show how this concavity of the regret-function is in line with the Prospect Theoretical notion of risk seeking behavior in the domain of losses.
