Utility means it the power to satisfy a want or a desire of a customer.
Measurement of utility
We measure utility in unit which helps to understand consumer behaviour it is useful and analytical distinguish between the two utility concept
Initial utility-it refers utility which is derived by consuming first unit of a commentator utility gained by taking first last of water to quench the third will be initial utility it is also positive
Total utility. It refers to the sum total of satisfaction I which a consumer is used by consuming the various unit of commodity
Marginal utility-marginal utility that additional unit in total utility which by can be defined as to increase or decrease one or two unit in the rate of consumption
Relationship between total utility and marginal utility
Quantity TU | Marginal Utility
1. 10. | Initial utility
2. 18 .| 18 - 10 =8
3. 24. |. 24 - 8 6
4. 28. | 28 - 4 = 4
5. 30. | 30 - 28=2
6. 30. | 0
7. 28. | 28-30=-2
It is clarified from diagram that you till total utility increases as were successive unity you is consume. Red 6th unit total total utility is constant then it will be declining on 17 8 which is 28
It is clarify that from the diagram that total utility and marginal utility start from same point when total utility false marginal utility becomes negative.

Cardinal Utility. Ordinarily utility
Introduction of Cardinal Utility
Marshall provides a Cardinal Measurements of utility.It also called Marshallian theory
Higher the price paid buy consumers for a commodity.higher shall be it's utility and vise versa in lower. Price can be measured of utility of number.In this way consumer is assumed to be capable of assign to every commodity.
Assumption of cardinal utility
Consumer is rational being
- .Consumer poses for perfect knowledge of the price in the market
- .The choice of goods are certain in market
- .there are no substitute and the earth the utility are measurable in terms of money
- . The tastes of consumer do not change
- .utility of different commodity are independent of each other
in general freakonomics now believe that utility is measurable in cardinal number indeed it was a reaction against an reality of cardinal measurement that gave rise to ordinalism
Criticism of cardinal utility theory
- . Utility is subjective
- . Cardinal measurement of utility is not possible
- .Everycom entity is not an independent commodity
- . Marginal utility cannot be estimated for all comedies
- . Marginal utility of money does not remain constant
- . Do not explain giffen paradox-It has no answer to explain why demand curve of many inferior goods slope up words from left to right
