In behavioral economics, time preference (or time discounting, [1] delay discounting, temporal discounting, [2] long-term orientation [3]) is the current relative valuation placed on receiving a good at an earlier date compared with receiving it at a later date. [1] Applications for these preferences include finance, health, climate change.
Time discounting or temporal discounting is a wide range of ideas involving the connection between time and the extent to which an object, situation, or course of action is seen as valuable. The overall theory is that people put more value and worth into immediate events and outcomes, and apply less value to future outcomes or events. According ...
Hyperbolic discounting is mathematically described as = + where g(D) is the discount factor that multiplies the value of the reward, D is the delay in the reward, and k is a parameter governing the degree of discounting (for example, the interest rate).
In findings presented in the journal Proceedings of the Royal Society B in 2021, Marine Biological Laboratory, researchers described cuttlefish (Sepia officinalis) that were able to pass an adapted version of the marshmallow test. Cephalopods engage in "future-oriented foraging" and the nine-month-old cuttlefish in the experiments were able to ...
Picoeconomics is a term Ainslie used to describe the different implications of an experimental discovery: the tendency for people to have a stronger preference for more immediate payoffs relative to later payoffs, where the tendency increases the closer to the present both payoffs are. Given two similar rewards, humans show a preference for one ...
Intuitively, it seems odd that the welfare of an 80-year-old born in 1970 is intrinsically superior to the welfare of an 80-year-old born in 1980; in the context of social (rather than private) discount rates, when asked for their preferences over the welfare of others, most peoples' apparent "pure time preferences" becomes smaller or even ...
In economics, dynamic inconsistency or time inconsistency is a situation in which a decision-maker's preferences change over time in such a way that a preference can become inconsistent at another point in time. This can be thought of as there being many different "selves" within decision makers, with each "self" representing the decision-maker ...
The term of present bias was coined in the second half of the 20th century. In the 1930s economic research started investigating time preferences. The findings led to the model of exponential discounting, thus time consistent discounting. However, later research led to the conclusion that time preferences were indeed not consistent, but ...
