An individual's willingness to share resources declines as the social distance between the decision maker and the recipient increases, which is known as social discounting. This social-distance-dependent prosocial behavior is likely to be influenced by the region in which individuals were raised. Based on previous studies on social discounting, this research focuses on the differing social dist...

Consumers spend their money to acquire both material products and experiences. While much can be said about differences between material and experiential purchase, little is known about consumers’ impatience towards such products. The authors propose that these items are different in terms of how willing consumers are towards delaying them, and also in how steeply this discounting declines over...

Dynamic decision-making without commitment is usually modelled as a game between the current and future selves of the decision maker. It has been observed that if the time-horizon is infinite, then such games may have multiple subgame-perfect equilibrium solutions. We provide a sufficient condition for uniqueness in a class of such games, namely infinitely repeated decision problems with discou...

Using a continuous impulsivity and risk platform (CIRP) that was constructed using a video game engine, choice was assessed under conditions in which waiting produced a continuously increasing probability of an outcome with a continuously decreasing magnitude (Experiment 1) or a continuously increasing magnitude of an outcome with a continuously decreasing probability (Experiment 2). Performanc...

We study the impact of deliberation time on intertemporal choice. Using studies in an online labor market, the laboratory, and a field experiment in the Democratic Republic of Congo, we show that the introduction of waiting periods – designed to prompt deliberation by temporally separating news about choice sets from choices themselves – cause a shift towards substantially more patient decision...

Neuroeconomic conditions for "rational addiction" (Becker & Murphy 1988) have been unknown. This paper derived the conditions for "rational addiction" by utilizing a nonlinear time-perception theory of "hyperbolic" discounting, which is mathematically equivalent to the q-exponential intertemporal choice model based on Tsallis' statistics. It is shown that (i) Arrow-Pratt measure for temporal co...

On the origin of utility, weighting, and discounting functions : how they get their shapes and how to change their shapes. A note on versions: The version presented in WRAP is the published version, or, version of record, and may be cited as it appears here. W e present a theoretical account of the origin of the shapes of utility, probability weighting, and temporal discounting functions. In an...
