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.
Some argue that the only reason for discriminating against future generations is that these generations might cease to exist in the future. Thus the rate of time preference should equal zero since the probability for such a catastrophic event is so low (assumed to be 0.1% per year). [8] This infers that there is equal weight given to all ...
The phenomenon of hyperbolic discounting is implicit in Richard Herrnstein's "matching law", which states that when dividing their time or effort between two non-exclusive, ongoing sources of reward, most subjects allocate in direct proportion to the rate and size of rewards from the two sources, and in inverse proportion to their delays. [8]
An alternative way to use high–low pricing is to increase the price for a short time, sometimes as much as 500 per cent, after which it is "discounted" to what its normal selling price. [4] After the price is reduced to the "sale" price, it may often stay at that price for a long time, sometimes longer than two weeks, after which customers ...
Revealed preference theory was a means to reconcile demand theory by defining utility functions by observing behaviour. Therefore, revealed preference is a way to infer the preferences of individuals given the observed choices. It contrasts with attempts to directly measure preferences or utility, for example through stated preferences.
A simple example of a preference order over three goods, in which orange is preferred to a banana, but an apple is preferred to an orange. In economics, and in other social sciences, preference refers to an order by which an agent, while in search of an "optimal choice", ranks alternatives based on their respective utility.
A reasonable preference ordering should satisfy several axioms: [4]: 66–69 1. Monotonicity: if the utility of one individual increases, while all other utilities remain equal, R should strictly prefer the second profile. For example, it should prefer the profile (1, 4, 4, 5) to (1, 2, 4, 5). Such a change is called a Pareto improvement. 2.
Single-peaked preferences are a class of preference relations. A group has single-peaked preferences over a set of outcomes if the outcomes can be ordered along a line such that: Each agent has a "best outcome" in the set, and; For each agent, outcomes that are further from his or her best outcome are preferred less.
