hyperbolic discounting

5 9 29 If overcoming the tendency to temporary preference takes learning, the next obvious task for experimenters is to test theories of how and when this learning occurs (e.g.
The Science of Self-Control.13 The rate depends on a variety of factors, including the species being observed, age, experience, and the amount of time needed to consume the reward.Lakshmi Mani, a product designer working in San Francisco.For example, in an early study subjects said they would be indifferent papa john's discount coupons delhi between receiving 15 immediately or 30 after 3 months, 60 after 1 year, or 100 after 3 years.7, that is, subjects' choices "match" these parameters.In Loewenstein, George; Read, Daniel; Baumeister, Roy.Cavewoman Lakshmi never had to choose between eating a pig today versus investing it in a pig 401K that would yield a 4X return in the future.Cocaine self-administration in female rats".New York: Russell Sage Foundation.These indifferences reflect annual discount rates that declined from 277 to 139 to 63 as delays got longer.
However, the methods that they use to calculate that amount and the answers that they get will be different, and only the exponential discounter will use the correct method and get a reliably correct result: The exponential discounter will think "The best alternative investment available.
However, you instead choose to splurge on an expensive night out with friends, which is more fun right now, but might not be the best choice for future you.
21 The degree of discounting is vitally important in describing hyperbolic discounting, especially in the discounting of specific rewards such as money.This dynamic inconsistency happens because hyperbolas distort the relative value of options with a fixed difference in delays in proportion to how far the choice-maker is from those options.But the pattern follows a hyperbola, so once a certain time threshold is crossed, the devaluing effect of time diminishes; for example, most will opt to take 100 in ten years over 50 in nine years.Why am I this way?Green, Leonard and Myerson, Joel (2004) A discounting framework for choice with delayed and probabilistic rewards.Unfortunately, the choices you have to make in everyday life are not as clear or easily comparable.Too little is saved, he says."On hyperbolic discounting and uncertain hazard rates".Its easy to assume that future you has boundless energy, drive, and motivation.The representation of this approach in a maths formula is said to be hyperbolic rather than exponential.
