3. 3. Definition* The law of diminishing marginal utility describes a familiar and fundamental tendency of human behavior.* “The law of diminishing marginal utility states that, “as a consumer consumes more and more units of a specific commodity, utility from the successive units goes on diminishing”. 3
4. 4. a law of diminishing marginal utility MARGINAL UTILITY The consumption of various unit of commodity. TOTAL UTILITY(TU) The sum total of satisfaction which a consumer receives byconsuming the various unity of the commodity.(The more unit of a commodity he consumes, the greater will be histotal utility) 4
5. 5. The concept of marginal utility grew out of attempts by economists to explain the determination of price.•Marginal utility can be defined as a measure of relative satisfactiongained or lost from an increase or decrease in the consumption ofthat good or service.•Examples –A motor vehicle or A haircut 5
6. 6. The law of diminishing utility is based upon three facts.* Firstly The wants of a man are unlimited but single want can be satisfied.* Secondly Different goods are not perfect substitutes for each other in the satisfaction of various particular wants.* Thirdly There is no change in the tastes of the consumers. 6

17. 17. * It is clear that in a given span of time :-* The first cone of ice cream taken man gives 20 units of utility.* When he takes second cone of ice cream, the marginal utility goes down to 12 units.* When he consumes fifth cone of water, the marginal utility drops down to zero and if the consumption of water is forced further from this point, the utility changes into disutility (–3), and soon, until he pukes…* Here it may be noted that the utility of the successive units consumed diminishes not because they are of inferior in quality than that of others. We assume that 17 all the units of a commodity consumed are exactly alike
