Self-regulation is a complex process that involves consumers’ persistence, strength, motivation, and commitment in order to be able to override short-term impulses. In order to be able to pursue their long-term goals, consumers typically need to forgo immediate pleasurable experiences that are detrimental to reach their overarching goals. Although this sometimes involves resisting to simple and small temptations, it is not always easy, since the lure of momentary temptations is pervasive. In addition, consumers’ beliefs play an important role determining strategies and behaviors that consumers consider acceptable to engage in, affecting how they act and plan actions to attain their goals. This dissertation investigates adequacy of some beliefs typically shared by consumers about the appropriate behaviors to exert self-regulation, analyzing to what extent these indeed contribute to the enhancement of consumers’ ability to exert self-regulation.
