As he keeps eating more and more food, his appetite will decrease and come to a point where he does not want to eat anymore. Marshall (1920, 1961) continued this line of thinking, giving a more technical definition. He stated that the additional benefit which a person derives from a given increase of his stock of a thing diminishes with every increase in the stock that he already has. According to Marshall, ‘The additional benefit which a person derives from a given increase of his stock of a thing diminishes with every increase in the stock that he already has’. The assumptions of the Law of Diminishing Marginal Utility include that the consumer has a fixed budget, the good being consumed is homogeneous, and the consumer’s preferences remain constant.
Explain the Law of Diminishing Marginal Utility
If budgets are fixed, a lower price means more can be consumed – providing more ‘real’ income. For example, if a consumer has a budget of $2400, then at a price of $6(at point A) he or she can buy 400 units of good X. The Law of Diminishing Marginal Utility may not apply to addictive substances or hobbies, as the marginal utility of each additional unit may not decrease for an addict or enthusiast. From the above discussion, it can be inferred that as more and more units of a commodity are consumed, the marginal utility from each successive unit goes on diminishing. Based on the above assumptions, the law of diminishing marginal utility can be explained with help of the following schedule. Sales techniques for each customer are altered depending on the consumer’s current marginal utility potential.
Whether food or clothing or gadgets or entertainment, the first round of consumption provides more satisfaction compared to second-round consumption and so on. If you haven’t had breakfast yet, that first hot dog will be delicious and the second one won’t be bad either. After a while, you’ll become averse to eating hot dogs and may even get sick (have negative utility) if you continue to eat more. It is more immediately profitable to lay off 10% of the manufacturing staff, and the manufacturing line may make do with the remaining resources for the first few vehicles. However, after a while, the marginal manufacturing benefit decreases due to a shortage of staff.
The first slice has a large benefit because you were hungry and this is the first food you’ve eaten lately. The law of diminishing marginal utility applies to both consumers and businesses. The law of diminishing marginal utility affects both consumers and businesses through its several components. Alfred Marshall’s Principles of Economics gave the law of diminishing marginal utility. A real-life example of the law of diminishing marginal utility is food.
Marginal utility can differ based on the consumer and the specific product. The benefit received for consuming every additional unit will be different, and the law of diminishing marginal utility states that this benefit will eventually begin to decrease. The law of diminishing marginal revenue states that once maximum efficiency is reached, the amount of profit earned per unit will decrease. This can be due to demand saturation (i.e., diminishing marginal utility for consumers) or escalating production costs (i.e., diminishing marginal product for production).
Water – Diamond Paradox:
The law of diminishing marginal utility dictates many aspects of how a company operates. A law of diminishing marginal utility given by company must adjust how many goods it carries in inventory and its marketing and sales tactics to reduce the impact of diminishing marginal utility. This is an important concept for companies that have a diverse product mix. If the shop only marketed a single product, consumers would likely grow tired of that product; its marginal utility would diminish. This concept is especially important for companies that carry inventory.
- Here are some ways diminishing marginal utility progresses along a business process.
- The second unit results in a lesser degree of satisfaction, and so on.
- Eventually, you may become full, and the satisfaction you derive from each additional slice of pizza will become negative.
Law of Diminishing Marginal Utility (DMU) : Meaning, Assumptions & Example
Yes, the Law of Diminishing Marginal Utility can be applied to any good or service that a person consumes, including food, clothing, electronics, and more. The Law of Diminishing Marginal Utility also has applications in other areas of economics, such as public policy. The concept is used to determine the optimal level of taxation and to understand the relationship between income and happiness.
Electricity prices – marginal cost pricing
The neoclassical microeconomic theory assumes that all commodities are infinitely divisible. This allows economists and mathematicians to assume continuous utility functions and use calculus to analyze marginal changes. John is extremely hungry and goes to a restaurant that offers a buffet. The amount of satisfaction gained by John from a plate of food is directly proportional to John’s hunger level. Therefore, the first plate of food will give John more satisfaction (utility) than the second plate of food, which in turn will give John more satisfaction than the third plate of food. Suppose your mother offers you food after you just got home from work.
- The law of diminishing marginal utility predicts that consumers will gain more satisfaction from the first unit of a product they purchase than from additional purchases of the same product.
- The neoclassical microeconomic theory assumes that all commodities are infinitely divisible.
- This has given them satisfaction, as is evident through countless social media fanatics and gate-crashers.
- One of the most important applications is in the pricing of goods and services.
The principle of diminishing marginal utility is one way to understandwhy a demand curve slopes downwards. An individual consumer demonstrates the law of diminishing marginal utility every time he or she consumes a product. The first unit that is consumed satisfies the consumer’s greatest need.
Of course, marginal utility depends on the consumer and the product being consumed. Many people only need one; there is an extremely large jump in utility from owning zero cell phones to owning one cell phone. Should a market become quickly saturated with people who all own cell phones, a company can be stuck holding inventory. In most cases, the income and substitution effect combine to create thenegative price/demand relationship.
Above gives the utility derived by a person from successive units of consumption of apples. While there may be some exceptions, the principle of diminishing marginal utility holds for most goodsand services consumed. Utility refers to the satisfaction or value that an individual derives from consuming a good or service. It is a subjective measure that varies from person to person and from situation to situation.
This law is essential as it also states that more consumption of commodities may result in less satisfaction. In the above diagram, units of commodity x are measured on X axis and marginal utility is measured on Y axis. Various points of MU are plotted on the graph as per the given schedule.

It is a concept that explains the relationship between the consumption of a good and the utility derived from it. The law states that as a consumer consumes more and more of a good, the marginal utility derived from each additional unit of the good decreases. In simple words, the more a consumer consumes a good, the less satisfaction they derive from each additional unit of the good. From Table 3.1 and figure 3.1 it is very clear that the marginal utility (addition made to the total utility) goes on declining. The consumer derives 20 units of utility from the first apple he consumes. When he consumes the apples continuously, the marginal utility falls to 5 units for the fourth apple and becomes zero for the fifth apple.
The X-axis represents the quantity of the goods consumed, while the Y-axis represents the marginal utility derived from each additional unit consumed. The first apple gives him great pleasure (higher utility) as he is hungry; when he takes the second apple, the extent of his hunger will reduce. If he continues to take additional apples, the utility derived from the third apple will be less than that of the second one. In this way, the additional utility (marginal utility) from the extra units will go on decreasing.
Most consumers spread their income among different varieties of goods when making choices. People prefer a variety of goods as consuming more and more of any one good diminishes the marginal satisfaction obtained from continued use of that good. This law explains a significant relationship between utility and the quantity of a commodity that is consumed. Marginal utility is the enjoyment a consumer gets from each additional unit of consumption. The utility gained from the second bottle of water is the marginal utility if you buy a bottle of water and then a second one.
