Motivational Goal Bracketing with Non-Rational Goals [PDF]

SSRN Electronic Journal, 2021
Abstract We provide a tractable model of motivational goal bracketing by a present-biased individual, extending previous work to show that the main insights from models with rational goals carry over to a setting with non-rational goals. Goals motivate because they serve as reference points that make substandard performance psychologically painful. A
