LAW OF DIMINISHING MARGINAL UTILITY: The law of diminishing marginal utility describes a familiar and fundamental tendency of humanbehavior. The law of diminishing marginal utility states that: “As a consumer consumes more and more units of a specific commodity, the utility from the successiveunits goes on diminishing”. Mr. H. Gossen, a German economist, was first to explain this law in 1854. Alfred Marshal later onrestated this law in the following words: “The additional benefit which a person derives from an increase of his stock of a thing diminishes withevery increase in the stock that already has”.

If the marginal utility of money changes with the increaseor decrease in income, it then cannot yield correct measurement of the marginal utility of the good.(iii) Diminishing marginal utility: Another important assumption of utility analysis is that the utilitygained from the successive units of a commodity diminishes in a given time period.(iv) Utility is additive: In the early versions of the theory of consumer behavior, it was assumed that theutilities of different commodities are independent. The total utility of each commodity is additive. 1 1 2 2 3 3 n n U = U (X ) + U (X ) + U (X )………. U (X ) Handouts by: Sachin Pourush * 4.

If there is interval between the consumption of the same units of the commodity,the law may not hold good.
