Discounting of reward sequences: a test of competing formal models of hyperbolic discounting

Humans are known to discount future rewards hyperbolically in time. Nevertheless, a formal recursive model of hyperbolic discounting has been elusive until recently, with the introduction of the hyperbolically discounted temporal difference (HDTD) model. Prior to that, models of learning (especially reinforcement learning) have relied on exponential discounting, which generally provides poorer ...

Physical and cognitive effort discounting across different reward magnitudes: Tests of discounting models

The effort required to obtain a rewarding outcome is an important factor in decision-making. Describing the reward devaluation by increasing effort intensity is substantial to understanding human preferences, because every action and choice that we make is in itself effortful. To investigate how reward valuation is affected by physical and cognitive effort, we compared mathematical discounting ...

A Simple Axiomatization of Quasi-hyperbolic Discounting∗

This paper provides a novel axiomatization of quasi-hyperbolic discounting, which imposes consistency restrictions directly on the intertemporal tradeoffs. The experimental design proposed in this paper will be useful for experimental work since it renders the short-run discount factor elicitation independent of the utility function. This makes comparisons of impatience across a spectrum of dif...

Uncertainty and Hyperbolic Discounting

Empirical studies in economics and behavioral ecology suggest that, ceteris paribus, animals and humans appear to place less weight on the future than on the present, i.e., they act as though they discount future payoffs. Furthermore (and more interestingly), they do so with discount rates that increase as the time before those payoffs are realized grows shorter. In other words, subjects act as...
