Ultimatum Game Model Based on Facial Trait Inference

摘要

The existence of a beauty premium in the labor market suggests that appearance can exert effect in the real world. We explored facial trait inference-especially focused on facial attractiveness and facial trustworthiness-in an Ultimatum Game experiment, which is commonly used to examine economic decision making [1]. Based on the traditional FS model, which clearly described the function of ultimatum game, we modified and made improvements of it and constructed a model that was appropriate for our research. These findings point to important effects of facial trait inferences on decision and provide initial insight into the psychological processes regarding to the decision behavior.
