Abstract
We provide a simple geometric proof of the Gul and Pesendorfer’s (Econometrica 69(6):1403–1435, 2001) utility representation theorem about choice under temptation without self-control. We extract two incomplete orders from preferences: temptation relation and resistance relation. We characterize those relations geometrically and obtain temptation utility using a separation method à la Aumann (Econometrica 30(3):445–462, 1962).
