In economics, utility is a measure of preferences over some set of goods and services. The concept is an important underpinning of rational choice theory in economics and game theory, because it represents satisfaction experienced by the consumer of a good. A good is something that satisfies human wants. Explain features common to most operating systems. Most operating systems perform similar functions that include managing programs. Some utility programs are used primarily by select groups. For example, text editors.The utility programs is a type of system software that allows a user to perform maintenance-type tasks. Most operating system include several built-in utility. The backup utility allows users to make a. What are the most common desktop operating systems?

Some of the common Utility programs are those concerned with Searching They from BMIT 5103 at Information Technology High School. Since one cannot directly measure benefit, satisfaction or happiness from a good or service, economists instead have devised ways of representing and measuring utility in terms of economic choices that can be measured. Economists have attempted to perfect highly abstract methods of comparing utilities by observing and calculating economic choices. In the simplest sense, economists consider utility to be revealed in people's willingness to pay different amounts for different goods. Applications. Utility and indifference curves are used by economists to understand the underpinnings of demand curves, which are half of the supply and demand analysis that is used to analyze the workings of goods markets. Individual utility and social utility can be construed as the value of a utility function and a social welfare function respectively. When coupled with production or commodity constraints, under some assumptions these functions can be used to analyze Pareto efficiency, such as illustrated by Edgeworth boxes in contract curves. Such efficiency is a central concept in welfare economics. In finance, utility is applied to generate an individual's price for an asset called the indifference price. Utility functions are also related to risk measures, with the most common example being the entropic risk measure. Revealed preference. These 'revealed preferences', as they were named by Paul Samuelson, were revealed e. It has been already argued that desires cannot be measured directly, but only indirectly, by the outward phenomena to which they give rise: and that in those cases with which economics is chiefly concerned the measure is found in the price which a person is willing to pay for the fulfillment or satisfaction of his desire. At one time, it was assumed that the consumer was able to say exactly how much utility he got from the commodity. The economists who made this assumption belonged to the 'cardinalist school' of economics. Today utility functions, expressing utility as a function of the amounts of the various goods consumed, are treated as either cardinal or ordinal, depending on whether they are or are not interpreted as providing more information than simply the rank ordering of preferences over bundles of goods, such as information on the strength of preferences. Cardinal. For example, suppose a cup of orange juice has utility of 1. With cardinal utility, it can be concluded that the cup of orange juice is better than the cup of tea by exactly the same amount by which the cup of tea is better than the cup of water. One cannot conclude, however, that the cup of tea is two thirds as good as the cup of juice, because this conclusion would depend not only on magnitudes of utility differences, but also on the . A notable exception is in the context of analyzing choice under conditions of risk (see below). Sometimes cardinal utility is used to aggregate utilities across persons, to create a social welfare function. The argument against this is that interpersonal comparisons of utility are meaningless because there is no simple way to interpret how different people value consumption bundles. In the above example, it would only be possible to say that juice is preferred to tea to water, but no more. Ordinal utility functions are unique up to increasing monotone transformations. For example, if a function u(x). This means that the ordinal preference induced by these functions is the same. In contrast, cardinal utilities are unique only up to increasing linear transformations, so if u(x). Let X be the consumption set, the set of all mutually- exclusive baskets the consumer could conceivably consume. The consumer's utility functionu: X. If the consumer strictly prefers x to y or is indifferent between them, then u(x). Then this consumer prefers 1 orange to 1 apple, but prefers one of each to 2 oranges. In micro- economic models, there are usually a finite set of L commodities, and a consumer may consume an arbitrary amount of each commodity. This gives a consumption set of R+L. In the previous example, we might say there are two commodities: apples and oranges. If we say apples is the first commodity, and oranges the second, then the consumption set X=R+2. Note that for u to be a utility function on X, it must be defined for every package in X. A utility function u: X. They are usually monotonic and quasi- concave. However, it is possible for preferences not to be representable by a utility function. An example is lexicographic preferences which are not continuous and cannot be represented by a continuous utility function. Petersburg paradox was first proposed by Nicholas Bernoulli in 1. Daniel Bernoulli in 1. Bernoulli argued that the paradox could be resolved if decision- makers displayed risk aversion and argued for a logarithmic cardinal utility function. The first important use of the expected utility theory was that of John von Neumann and Oskar Morgenstern, who used the assumption of expected utility maximization in their formulation of game theory. Neumann. The required assumptions are four axioms about the properties of the agent's preference relation over 'simple lotteries', which are lotteries with just two options. Intuitively, if the lottery formed by the probabilistic combination of L. Under the four assumptions mentioned above, the agent will prefer a lottery L2. A variety of generalized expected utility theories have arisen, most of which drop or relax the independence axiom. As probability of success. Specifically for any utility function, there exists a hypothetical reference lottery with the expected utility of an arbitrary lottery being its probability of performing no worse than the reference lottery. Suppose success is defined as getting an outcome no worse than the outcome of the reference lottery. Then this mathematical equivalence means that maximizing expected utility is equivalent to maximizing the probability of success. In many contexts, this makes the concept of utility easier to justify and to apply. For example, a firm's utility might be the probability of meeting uncertain future customer expectations. The (indirect) utility function for money is a nonlinear function that is bounded and asymmetric about the origin. The utility function is concave in the positive region, reflecting the phenomenon of diminishing marginal utility. The boundedness reflects the fact that beyond a certain point money ceases being useful at all, as the size of any economy at any point in time is itself bounded. The asymmetry about the origin reflects the fact that gaining and losing money can have radically different implications both for individuals and businesses. The non- linearity of the utility function for money has profound implications in decision making processes: in situations where outcomes of choices influence utility through gains or losses of money, which are the norm in most business settings, the optimal choice for a given decision depends on the possible outcomes of all other decisions in the same time- period. This is so because if we take changes in peoples' behavior in relation to a change in prices or a change in the underlying budget constraint we can never be sure to what extent the change in behavior was due to the change in price or budget constraint and how much was due to a change in preferences. In the case of cardinal utility it is impossible to measure the level of satisfaction . In case of ordinal utility, it is impossible to determine what choices were made when someone purchases, for example, an orange. Any act would involve preference over a vast set of choices (such as apple, orange juice, other vegetable, vitamin C tablets, exercise, not purchasing, etc.). Whether people gain utility from coherence of wants, beliefs or a sense of duty is key to understanding their behavior in the utility organon. Principles of Economics.
