Self–Control and Random Strotz Representations∗

NAIVETÉ ABOUT TEMPTATION AND SELF-CONTROL: FOUNDATIONS FOR NAIVE QUASI-HYPERBOLIC DISCOUNTING By

We introduce and characterize a recursive model of dynamic choice that accommodates naiveté about present bias. The model incorporates costly self-control in the sense of Gul and Pesendorfer (2001) to overcome the technical hurdles of the Strotz representation. The important novel condition is an axiom for naiveté. We first introduce appropriate definitions of absolute and comparative naiveté f...

The Revealed Preference Theory of Changing Tastes†

We analyze preferences over finite decision problems in order to model decision-makers with “changing tastes”. We provide conditions on these preferences that identify the Strotz model of consistent planning. Building on an example by Peleg and Yaari (1973), we show that for problems with infinitely many choices, Strotz’s representation of preferences may not be well-defined. For that case, we ...

Multivariate Operator-Self-Similar Random Fields

Multivariate random fields whose distributions are invariant under operatorscalings in both time-domain and state space are studied. Such random fields are called operator-self-similar random fields and their scaling operators are characterized. Two classes of operator-self-similar stable random fields X = {X(t), t ∈ R} with values in R are constructed by utilizing homogeneous functions and sto...

Comparison the Effectiveness of Positive Self-Talk Training and Self-Control Training Methods on Self-Efficacy Beliefs of High School Girl Students

Background and Objective: The review of literature suggests self-talk and self-control as effective methods for improving mental health and achievement of goals. Considering the importance of improving the level of self-efficacy of students, this study aimed to compare the effectiveness of positive self-talk and self-control training on self-efficacy of 10th high school female students.
