“…The idea of a preference, impatience, or impulsivity for advancing the timing of future satisfaction has been central to research on intertemporal choice. Building on the classical exponential discounted utility (EDU) model, a plethora of different models of intertemporal choice have been developed over the years (Dhami, 2016), each challenging the critical preference conditions of the EDU model, most notably time consistency and intertemporal separability (Bleichrodt, Keskin, Rohde, Spinu, & Wakker, 2015). First, the rejection of constant (exponential) discounting, although some empirical studies found support for consistent impatience over time (e.g., Benhabib, Bisin, & Schotter, 2010;Harrison, Lau, & Williams, 2002), has led to the development and testing of hyperbolic (Loewenstein & Prelec, 1992), quasi-hyberbolic (Laibson, 1997), and subadditive (Read, 2001;Read & Roelofsma, 2003) models.…”
