# How does hyperbolic discounting differ from exponential discounting and what implications does it have?

Contents

This contrasts with exponential discounting, in which valuation falls by a constant factor per unit delay and the discount rate stays the same. … The most important consequence of hyperbolic discounting is that it creates temporary preferences for small rewards that occur sooner over larger, later ones.

## What is the difference between exponential and hyperbolic discounting?

Whereas an exponential curve has a constant discount rate, a hyperbolic discount curve has a higher discount rate in the near future and lower discount rate in the distant future.

## What is hyperbolic discounting in psychology?

Hyperbolic discounting is our inclination to choose immediate rewards over rewards that come later in the future, even when these immediate rewards are smaller.

## How does hyperbolic discounting work?

Put simply, hyperbolic discounting happens when people would rather receive \$5 right now than \$10 later. That’s it. People value the immediacy of time over the higher value of money. Expressed another way, hyperbolic discounting is a person’s desire for an immediate reward rather than a higher-value, delayed reward.

## What is exponential discounting model?

Exponential discounting implies that the marginal rate of substitution between consumption at any pair of points in time depends only on how far apart those two points are. … A key aspect of the exponential discounting assumption is the property of dynamic consistency— preferences are constant over time.

## How is hyperbolic discounting measured?

The hyperbolic model (Mazur, 1987) is a descriptive model, calculated as V = A / (1+kD), where V is the present value, A is the future amount, D is the delay,1 and k is the discount rate.

## What is the principle of discounting?

According to the discounting principle, the perceived role of a given cause in leading to a given effect is diminished when other possible causes for that event are also detected.

## What is the discount factor in finance?

Discount Factor is a weighing factor that is most commonly used to find the present value of future cash flows and is calculated by adding the discount rate to one which is then raised to the negative power of a number of periods.

## What is discounting in psychology?

In psychology, the discounting principle refers to how someone attributes a cause to an eventual outcome. Discounting in psychology is sometimes intertwined with the augmentation principle, which takes the discounting principle evaluation and then adjusts choices based this.

## Is hyperbolic discounting a cognitive bias?

Hyperbolic discounting, also called “present bias,” is a cognitive bias, where people choose smaller, immediate rewards rather than larger, later rewards.

## Is temporal discounting rational?

The best justification of time-discounting is roughly that it is rational to care less about your more distant future because there is less of you around to have it. … Most people exhibit at least positive time-preference for fixed monetary sums. For instance, you would prefer \$100 now to \$100 in a year’s time.

## What is temporal discounting theory?

Temporal discounting refers to an individual’s tendency to perceive a desired result in the future as less valuable than one in the present, which is also known as time discounting or delay discounting (Rodzon et al., 2011).

## What is quasi hyperbolic discounting?

Hyperbolic discounting is a behavioral bias which describes the tendency for people to increasingly choose a smaller-sooner reward over a larger-later reward as the delay occurs sooner rather than later in time.

## What is the Beta Delta model?

According to the beta-delta model, techniques for increasing the likelihood that this individual will take the preventive health measure include reducing the up-front costs or offering her a commitment device. Recent field studies, however, have documented the success of another technique.
