Law of Diminishing Marginal Returns: Definition, Example, Use in Economics

In this episode of tutor2u’s A-Level Economics Mastery Series, Geoff Riley dives into the fascinating world of Utility Theory and the Law of Diminishing Marginal Utility. Learn how economists explain consumer choices and the downward-sloping demand curve through concepts like total utility, marginal utility, and the point of maximised satisfaction. Businesses can use the law of diminishing marginal utility to understand consumer behavior, price their goods and services, and diversify their offerings. The law of diminishing marginal utility also will not apply if the commodity being considered is money. The utility of money does not decrease as a person acquires more of it. The law of diminishing marginal utility affects how businesses price their goods and services.

Negative Utility

2. This concept is helpful for explaining the principles of supply and demand, and is essential aspects of models of imperfect competition.
3. Of course, some people do like to take risks, and we have already explained how the fact that some people may like extreme sports, etc. does not weaken or qualify the strong results of the LARA utility function – human preferences remain generally MU decreasing.
4. However, if the two items complement each other, then the exchange ratios might remain constant.19 In situations where traders can improve their position by offering trades that are more favorable to complementary traders, they are likely to do so.
5. After that, every unit of consumption to follow holds less and less utility.

It necessarily leads to a decline in its exchange value — when compared with a situation in which the money stock had remained unchanged; and it should also be noted here that a rise in the money stock affects different market agents differently (the “Cantillon Effect”). Businesses can use this principle to structure their workforce. For example, a company may benefit from having three accountants on its staff. But if there is no real need for a third, hiring one results in a diminished utility due to the minimum benefit gained. If you have two accountants but no one to process paperwork, hiring a new administrative assistant has a higher level of utility than hiring a third accountant. In this case the law also applies to societies – the opportunity cost of producing a single unit of a good generally increases as a society attempts to produce more of that good.

With each subsequent increase in the level of consumption, Law of Diminishing Marginal Utility mentions that an increase in consumption reduces the additional utility acquired. The change in total utility caused by a one-unit change in the level of consumption is referred to as Marginal Utility. In particular, the law explains that marginal utility, which is defined as satisfaction or benefit, decreases gradually with the level of consumption. There is an inverse relationship between returns of inputs and the cost of production,24 although other features such as input market conditions can also affect production costs. Suppose that a kilogram of seed costs one dollar, and this price does not change.

1. The law of diminishing marginal utility predicts how consumers will react to a certain level of supply.
2. For example, a factory employs workers to manufacture its products, and, at some point, the company operates at an optimal level.
3. There are many ways, therefore, in which the theory of diminishing marginal utility has been historically developed.
4. Each dish of food fills Ray up, reducing the amount of satisfaction he will derive from the plates of food that come afterwards.
5. We often find examples of diminishing marginal utility in the food and drink sector – consider the temptations of an all you can eat buffet or a decision to start and then finish off a tube of crisps!
6. At the same time, the world economy is undergoing significant changes.
7. It can inform a business’ marketing and sales strategies, as well.

This concept of a budget model is assessed against how much utility consumers gain from additional purchases. The Law of Diminishing Marginal Utility is introduced to explain consumers’ behavior related to purchasing and the satisfaction of their decisions. Consumers want to maximize their utility function subject to their budget constraint. But this decision represents an efficient market operation that brings them the highest level of satisfaction, given their budget constraint. To illustrate the concept of a budget constraint, let’s first assume that a consumer derives utility from the first $5 the consumer has to spend as a market constraint.

Total Utility vs. Marginal Utility

Proposed on the cusp of the First Industrial Revolution, it was motivated with single outputs in mind. The second assumption is that when you are spending money on a commodity, the marginal utility of money remains constant throughout. This facilitates the measurement of the utility of commodities in terms of money.

In case of a fall in the price of the commodity, the equality between marginal utility and price gets disturbed. Therefore, the consumer will consume more units of the good leading to a fall in the marginal utility. On the other hand, in case of a rise in the price of the commodity, he will consume less and achieve equilibrium too. In other words, as we consume more units of a good, the extra satisfaction that we derive from the extra unit keeps falling. However, it is important to remember that the marginal utility declines NOT the total utility. If a person has a good or service that has less value to them compared to another good or service they could trade it for, it would be beneficial for them to make that trade.

So, the amount of money that you are willing to spend for a unit of commodity rather than going without it is the measure of utility that you derive from the said commodity. IntroductionBy now, the increasing impact of economic globalization on national economies is clear. Processes that have been at work for decades, if not centuries, have come to the fore, creating widespread debate on their characteristics, causes, and consequences. At the same time, the world economy is undergoing significant changes. The end of the Soviet Union as a significant political and economic force has led the economies of the former Union to open to international trade and foreign… IntroductionVietnam has experienced rapid economic development over the last decade.

Understanding the Law of Diminishing Marginal Returns

A rise in the money stock will thus necessarily lead to a decrease in the marginal utility of the money unit (compared to the situation in which the money stock had remained unchanged). It is necessary to make certain assumptions in order for the law of diminishing marginal utility to hold true. Each premise stands on its own logic and makes sense on its own. It is untenable for the law of diminishing marginal utility to hold true if any of the assumptions are not true. The law of diminishing marginal utility directly impacts a company’s pricing because the price charged for an item must correspond to the consumer’s marginal utility and willingness to consume or utilize the law of diminishing marginal utility given by good.

Mill, A. Marshall, W. S. Jevons, C. Menger, F. Y. Edgeworth, U. Philips, F. A. Hayek, V. Pareto, C. Wicksteed, and P. Sraffa have accepted and utilized the law of diminishing marginal utility. It is worth appreciating how the classical economists discovered the law independently, since this theory was based not on statistical data but on experiments arrived upon the theories on the consumption of commodities by human beings. The neoclassical economists have advanced the law of diminishing marginal utility into the theory of consumer’s demand. The modern economists seek to establish the law on the basis of the feeling of human beings and to utilize it into the business policies and practices. All such formulations emphasize that the marginal utility of commodities decreases when commodities are consumed in larger quantities, and that is why the consumer’s behavior is dismal to its consumption.

He currently researches and teaches economic sociology and the social studies of finance at the Hebrew University in Jerusalem. After you eat the second slice of pizza, your appetite is becoming satisfied. You’re not as hungry as before, so you experience a smaller benefit and less enjoyment with the second slice than with the first.

If 50 people are employed, at some point, increasing the number of employees by two percent (from 50 to 51 employees) would increase output by two percent and this is called constant returns. It states that the total utility that you get from a collection of goods is a simple sum total of the separate utilities of each good. The theory further states that money is the measuring rod of utility.

This ensures that he derives maximum satisfaction by being in equilibrium in respect of the quantity of the commodity. The Law of Diminishing Marginal Utility states that if the consumption of a good or service increases, the satisfaction derived gradually increases but at a decreasing rate, to the point where it reaches zero. By developing praxeology, Mises showed that economic theory is the formal logic of the irrefutably true axiom of human action.
