An Empirical Study of Behavior on Overconfidence and Cell Phone Plan Selection―Questionnaire Survey with Hypothetical Question―

Abstract

This paper empirically analyzed the relationship between overconfidence and rate plan selection for cell phones based on the results of a questionnaire survey. In the hypothetical question, we asked the survey participants to select a plan which they considered to be the cheapest among the four cell phone rate plans. Empirical analysis shows that people with overconfidence tend to choose the cell phone plan by themselves.
