The effects of background music and sound in economic decision making: Evidence from a laboratory experiment

Abstract

This paper experimentally studies the effects of background music and sound on the preference of the decision makers for rewards in pairwise intertemporal choice tasks and lottery choice tasks. The participants took part in the current experiment, involving four treatments: (1) the familiar music treatment; (2) the unfamiliar music treatment; (3) the noise treatment and (4) the no music treatment. The experimental results confirm that background noise affects human performance in decision making under risk and intertemporal decision making, though the results do not indicate the significant familiarity effect that is a change of the preference in the presence of familiar background music and sound.Allais-type preferences; choice under risk; intertemporal choice; the familiarity effect
