UTILITY THEORY Flashcards
(34 cards)
Refers to want the satisfying power of a commodity. It is the satisfaction, actual or expected, derived from the consumption of a commodity.
Utility
differs from person-to-person, place-to-place and time-to-time.
Utility
“Utility is the ability of a good to satisfy a want”.
words of Prof. Hobson
The commodity is capable of satisfying human wants, we can conclude that the commodity has
Utility
How to Measure Utility?
Util
These are imaginary and psychological units that are used to measure satisfaction (utility) obtained from the consumption of a certain quantity of a commodity.
Utils
Suggested the measurement of utility in monetary terms.
Alfred Marshall
Utility can be measured in terms of money or price, which the consumer is willing to pay.
TRUE
Refers to the total satisfaction obtained from the consumption of all possible units of a commodity.
Total Utility (TU)
The additional utility is derived from the consumption of one more unit of the given commodity.
Marginal Utility (MU)
“Marginal utility is the addition made to the total utility by consuming one more unit of a commodity”
Chapman
MU is positive and TU is increasing till the 4th ice-cream. After consuming the 5th ice-cream, MU is zero and TU is maximum.
TRUE
stage of maximum satisfaction.
point of satiety
MU is negative
Disutility or Dissatisfaction
Is the opposite of utility. It refers to loss of satisfaction due to the consumption of too much of something.
Disutility
A commodity which satisfies any type of want, whether moral or immoral, socially desirable or undesirable, has utility, i.e., a knife has utility as a household appliance to a housewife, but it has also a utility to a killer for stabbing some body.
Utility has no Ethical or Moral Significance
It’s based on the cardinal counting numbers like 1, 2, 3, 4.
The Cardinal Approach or the Marginal Utility Approach
This means ranking items under consideration from most satisfaction to the least
Ordinal Approach or the Indifference Curve Approach
Utility of a commodity depends on a consumer’s mental attitude and assessment regarding its power to satisfy his particular want. Thus, utility of a commodity may differ from person to person. Psychologically, every consumer has his likes and dislikes and everyone determines his own level of satisfaction.
Utility is Psychological
Utility simply means the ability to satisfy a want. A commodity may have utility but it may not be useful to the consumer. For instance—A cigarette has utility to the smoker but it is injurious to his health.
Utility is not Necessarily Equated with Usefulness
The utility of a commodity varies in different situations in relation to time and place. Even the same consumer may derive a higher or lower utility for the same commodity at different times and in different places. For example—a person may find more utility in woolen clothes during the winter.
Utility is always Individual and Relative
Utility being a subjective phenomenon or feeling of a consumer cannot be expressed in numerical terms. So utility cannot be measured cardinally or numerically. It cannot be measured directly in a precise manner. Professor Marshall has however, unrealistically assumed cardinal measurement of utility in his analysis of demand.
Utility cannot be Measured Objectively:
Utility is the function of the intensity of want. A want that is unsatisfied and greatly intense will imply a high utility for the commodity concerned to a person.
Utility Depends on the Intensity of Want
A commodity may have utility but its consumption may not give any pleasure to the consumer, e.g., medicine or an injection. An injection or medicinal tablet gives no pleasure, but it is necessary for the patient.
Utility is Different from Pleasure
