The document introduces the dual-self model of choice proposed by Fudenberg and Levine. The model suggests that decision making involves both a long-run, patient self that aims to maximize utility over time and multiple short-run, impulsive selves that only care about immediate experiences. Experimental evidence shows that when choices involve immediate rewards versus delayed rewards, individuals are more likely to choose immediate rewards. This is consistent with the dual-self model in which short-run selves have a stronger influence on choices involving immediate rewards compared to long-run delayed options. The findings have implications for understanding consumer behaviors related to credit use, food choices, and other domains involving delayed gratification.
