This paper explores the effect of Buddhism on economic decision-making. Unfortunately, the field of Buddhist Economics lacks theoretical foundation to answer how Buddhists behave differently from non-Buddhists in economic decision-making. Instead, the field of behavioral economics better reconciles Buddhism with “enhancement effects” and the “time inconsistency model,” and the paper argues that Buddhists have a low level of enhancement effect and future discounting. Moreover, this paper establishes a theoretical framework for the Buddhists’ time inconsistency model by reinterpreting a multiple-self model. Lastly, the paper addresses the importance of “religious bias” on the legal system, particularly, in the area of international economic law.
