In expenditure minimisation the utility level is given and well as the prices of goods, the role of the consumer is to find a minimum level of expenditure required to reach this utility level. The utilitarian social choice rule is a rule that says that society should choose the alternative that maximizes the sum of utilities. While utility ...
In order to compare the different decision outcomes, one commonly assigns a utility value to each of them. If there is uncertainty as to what the outcome will be but one has knowledge about the distribution of the uncertainty, then under the von Neumann–Morgenstern axioms the optimal decision maximizes the expected utility (a probability ...
The expected utility hypothesis is a foundational assumption in mathematical economics concerning decision making under uncertainty. It postulates that rational agents maximize utility, meaning the subjective desirability of their actions. Rational choice theory, a cornerstone of microeconomics, builds this postulate to model aggregate social ...
The term E-utility for "experience utility" has been coined [2] to refer to the types of "hedonistic" utility like that of Bentham's greatest happiness principle. Since morality affects decisions, a VNM-rational agent's morals will affect the definition of its own utility function (see above).
The word utility is used to mean general well-being or happiness, and Mill's view is that utility is the consequence of a good action. Utility, within the context of utilitarianism, refers to people performing actions for social utility. By social utility, he means the well-being of many people.
The theory of consumer choice is the branch of microeconomics that relates preferences to consumption expenditures and to consumer demand curves.It analyzes how consumers maximize the desirability of their consumption (as measured by their preferences subject to limitations on their expenditures), by maximizing utility subject to a consumer budget constraint.

The main problem for total utilitarianism is the "mere addition paradox", which argues that a likely outcome of following total utilitarianism is a future where there is a large number of people with very low utility values. Parfit terms this "the repugnant conclusion", believing it to be intuitively undesirable. [4]
Given some ε > 0, an outcome is called ε-Pareto-efficient if no other outcome gives all agents at least the same utility, and one agent a utility at least (1 + ε) higher. This captures the notion that improvements smaller than (1 + ε ) are negligible and should not be considered a breach of efficiency.
