A Time/Utility Function (TUF), née Time/Value Function, specifies the application-specific utility that an action (e.g., computational task, mechanical movement) yields depending on its completion time. [1] [2] TUFs and their utility interpretations (semantics), scales, and values are derived from application domain-specific subject matter ...
In economics, utility is a measure of a certain person's satisfaction from a certain state of the world. Over time, the term has been used with at least two meanings. In a normative context, utility refers to a goal or objective that we wish to maximize, i.e., an objective function.
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.
In health economics, time trade-off (TTO) is a technique used to measure the quality of life that a person or group is experiencing. An individual will be presented with a set of directions such as: An individual will be presented with a set of directions such as:
In economics, discounted utility is the utility (desirability) of some future event, such as consuming a certain amount of a good, as perceived at the present time as opposed to at the time of its occurrence. [1]
Preferences are intertemporally homothetic if, across time periods, rich and poor decision makers are equally averse to proportional fluctuations in consumption. Models of modern macroeconomics and public finance often assume the constant-relative-risk-aversion form for within period utility (also called the power utility or isoelastic utility ...
In economics, exponential discounting is a specific form of the discount function, used in the analysis of choice over time (with or without uncertainty).Formally, exponential discounting occurs when total utility is given by
This principle is so well established that economists call it the "law of diminishing marginal utility" and it is reflected in the concave shape of most utility functions. [13] This concept is fundamental to understanding a variety of economic phenomena, such as time preference and the value of goods. Assumptions -
