The Law of Diminishing Marginal Utility

In terms of cardinal utility, the law states that the first unit yields more in comparison to the subsequent units and it results in a fall in marginal utility as consumption commodities figure increase.

The law is considered meaningful in the context of modern financial markets and institutions where it is used to analyze the inter-temporal choice made under ambiguity or as per social policies.

As acquisition increases, it decreases, and if consumption increases, the marginal utility may fall to zero, reaching the maximum total utility. 

This boost in commodities units results in creating negative marginal utility as it indicates discontentment.

It states that the marginal utility of each homogenous unit decline when the supply of units increases.

Also, the need for the large-sized units is higher as compared to small-sized units and vice verse. 

• For example – if one increases the dose of antibiotics to a certain level, it may not kill harmful antibodies when taken in a low amount, rather its intake can become harmful to the body. 

• People require an adequate amount of calories to maintain body functions but more than required calories can lead to health issues like obesity. 

• In everyday conditions – the companies offer free tickets to the British comedies movies– it may be useful only to a few; similarly, one will not invest in more than one washing machine for one family. 

Marginal indicate small change (increase or decline) that starts from baseline levels and it starts from the endowment (total resources).

The endowment is determined by physical laws, accidents of nature, and the outcomes of past decisions of individuals by themselves or others. 

It can be defined as the 1st derivative of total utility. The formulae used to determine the value is expressed as differential calculus.

Economists describe it as a quantifiable unit where different levels of utility can be compared along with a numerical value.

The quantitative concept allows arithmetic operations and assumptions of continuity and differentiability that increase tractability.
