Cardinal Utility Analysis/Approach:

DEFINITION AND EXPLANATION:

Cardinal Utility Analysis/Approach:

Human wants are unlimited and they are of different intensity. The means at the disposal of a man are not only scarce but they have alternative uses. As a result of scarcity of recourse, the consumer cannot satisfy all his wants. He has to choose as to which want is to be satisfied first and which afterward if the recourse permit. The consumer is confronted in making a choice.

For example, a man is thirsty. He goes to the market and satisfy his thirst by purchasing coca cola instead of tea. We are here to examine the economic forces which make him purchase a particular commodity. The answer is simple. The consumer buys a commodity because it gives him satisfaction. In technical term, a consumer purchases a commodity because it has utility for him. We now examine the tools which are used in the analyzes of consumer behavior.

Concept of Utility:

Jevon (1835 -1882) was the first economist who introduces the concept of utility in economics. According to him:

"Utility is the basis on which the demand of a individual for a commodity depends upon".

Utility is defined as:

"The power of a commodity or service to satisfy human want".

Utility is thus the satisfaction which is derived by the consumer by consuming the goods.

For example, cloth has a utility for us because we can wear it. Pen has a utility who can write with it. The utility is subjective in nature. It differs from person to person. The utility of a bottle of wine is zero for a person who is non drinker while it has a very high utility for a drinker.

Here it may be noted that the term ‘utility’ may not be confused with pleasure or unfullness which a commodity gives to an individual. Utility is a subjective satisfaction which consumer gets from consuming any good or service.

For example, poison is injurious to health but it gives subjective satisfaction to a person who wishes to die. We can say that utility is value neutral.

ASSUMPTIONS OF CARDINAL UTILITY ANALYSIS:

The main assumption or premises on which the cardinal utility analysis rests are as under.
 

(i) Rationality. The consumer is rational. He seeks to maximize satisfaction from the limited income which is at his disposal.
 

(ii) Utility is cardinally measurable. The utility can be measured in cardinal numbers such as 1, 3, 10, 15, etc. The utility is expressed in imaginary cardinal numbers tells us a great deal about the preference of the consumer for a good.
 

(iii) Marginal utility of money remains constant. Another important premise of cardinal utility of money spent on the purchase of a good or service should remain constant.
