Transferable utility is a term used in Cooperative game cooperative game theory and in economics . Utility is transferable if one player can losslessly transfer part of its utility to another player. Such transfers are possible if the players have a common currency that is valued equally by all. Note that being able to transfer cash payoff s does not imply that utility is transferable wealthy and poor players may derive a different utility from the same amount of money. Transferable utility is assumed in many cooperative game s, where the payoff s are not given for individual players, but only for coalitions. In this case the assumption implies that irrespective of the division of the coalitional payoff, members of the coalition enjoy the same total utility .

Utilitarianism expanded Problems The utility monster is a thought experiment in the study of ethics . It was created by philosopher Robert Nozick in 1974 as a criticism of utilitarianism . In the thought experiment, a hypothetical being is proposed who receives as much or more utility from each additional unit of a resource he consumes as the first unit he consumes. In other words, the utility monster is not subject to diminishing marginal returns with regard to utility, but instead experiences constant marginal returns, or even increasing marginal returns. Since ordinary people receive less utility with each additional unit consumed, if the utility monster existed, it would justify the mistreatment and perhaps annihilation of everyone else, according to the doctrine of utilitarianism. fact date February 2012 Robert Nozick believes that Utilitarian theory is embarrassed by the possibility of utility monsters who get enormously greater sums of utility from any sacrifice of others than these others lose . . . the theory seems to require that we all be sacrificed in the monster s maw, in order to increase total utility. ref Robert Nozick, Anarchy, State, and Utopia 1974 ref This thought experiment attempts to show that utilitarianism is not actually egalitarian , even though it appears to be at first glance.

Ordinal utility Economic theory theory states that while the utility of a particular good economics good or service cannot be measured using a numerical scale bearing economic meaning in and of itself, pairs of alternative bundles combinations of goods can be ordered such that one is considered by an individual to be worse than, equal to, or better than the other. This contrasts with cardinal utility theory, which generally treats utility as something whose numerical value is meaningful in its own right. Indifference curve mappings When a large number of bundles of goods are compared, the preferences of the individual can be seen.

The term utility station is used to describe fixed radio broadcasters disseminating signals that are not intended for reception by the general public but such members are not actively prohibited from receiving . Utility stations, as the name suggests, do broadcast signals that have an immediate practical use, by means of analog or usually digital modes most often utility transmissions are of a point to point nature, intended for a specific receiving station. Utility stations are most prevalent on shortwave frequencies, though they are not restricted to the shortwave frequencies. Examples of utility station and modes One common use of utility stations is disseminating weather information. Weather information is often broadcast using radioteletype RTTY and sending synoptic code s, or weather chart s are sent using radiofax , which are used by mariners and others. Airports make voice weather broadcasts on High frequency HF , known as VOLMET . Some examples include New York Radio, which broadcasts weather information for locations in the eastern United States, or Shanwick Radio, which does the same for Europe. HF frequencies are still often used for trans oceanic air traffic control. News agencies previously used RTTY for news stories, and, less commonly, radiofax for the images, although is no longer done.
