タイトル：Normal form games with self-control preferences
A majority of self-control models have been considered in the context of single-person decision making. However, one’s propensity to resist temptation may well depend on others’ behavior, as observed in smoking, overeating, and overspending behaviors. This study introduces a new class of normal form games in which players have self-control preferences (Gul and Pesendorfer (2001)) and a player’s ability to resist temptation depends on the other players’ actions. We propose an equilibrium concept and establish the existence of equilibria. In addition, we discuss how strategic interaction plays an important role in games with self-control preferences through examples such as the demand for commitment devices in the presence of bandwagon effects.
