The fundamental problem in utility analysis is that it makes the incorrect assumption that utility can only be stated in cardinal numbers. It implies that utils like 1, 2, and 3 can never accurately represent usefulness. When two things are consumed concurrently, satisfaction can be compared at best. Due to this drawback, utility analysis is shown to have minimal application in describing consumer equilibrium. When a consumer consumes the 6th unit of the commodity, s/he gets no utility or there is zero utility and as a result, total utility (TU) remains constant and becomes maximum.
He makes choices about the kinds of items to be bought to fulfil his desires. The primary goal is to maximise satisfaction from the goods and services he purchases with his income. To achieve the highest level of satisfaction, a consumer must follow certain rules or principles since resources are limited in nature in comparison to limitless demands. The two basic approaches for studying customer behaviour are the Cardinal Utility approach and Ordinal Utility Approach.
A shift in the demand curve is caused by changes in non-price factors, such as income, taste, expectation, population, price of comparable commodities, and so on. The rate at which a consumer substitutes one good for another as long as the latter good is providing equal satisfaction is known as the marginal rate of substitution. This approach states that utility can not be expressed in cardinal numbers like 1,2,3, and 4, rather it can only be ranked as high or low. The concept of cardinal utility was discarded by modern economists.
Often referred to as consumer purchasing behaviour, consumer behaviour consists of all of the factors that influence a consumer’s product search, selection, and purchase. We can also use the phrase to refer to the acquisition of services. Consumer behaviour’s post-purchase stage has also been included here. Marketers must understand consumer purchasing behaviour for their products to succeed. Marketers must understand what motivates a consumer to buy a certain product and what prevents him from doing so.

If there is a change in the price of one of the goods, this causes the budget line to rotate. The fall in the price causes outward radiation, which happens because there is a rise in the purchasing power of money. A linear demand curve’s elasticity may be simply assessed graphically. The elasticity of demand at each point on a straight line demand curve is determined by the ratio between the demand curve’s lower and upper segments at that position. Changes in the quantity demanded are indicated by movement along the demand curve.
Question
For the utility theory to work, it must be assumed that people are rational beings. In economics, rationality has a different connotation than it does in everyday speech. In economics, a person is “rational” if they make decisions that maximise utility.

In the diagram, where the IC curve is tangent to the budget line, that is point E is the optimal choice, and also a point of consumer equilibrium. This is the point where the slope of both, the indifference curve and budget line are equal to each other. The more the utility obtained from an item, the greater the need for it or the stronger the desire to have it. The same product can provide various levels of utility to different people. A consumer’s desire for an item is usually determined by the utility (or satisfaction) he obtains from it. Marginal Utility is the utility obtained from the last unit of a product or service.
Chapter 8: Theory of Supply
Thus, the law of DMU explains that, the more of a thing you have, the less you want to have more of it.In short, as consumption of identical units of commodity increases, MU diminishes. Utility refers to the satisfaction or benefit a consumer gets from consuming a good or service. There are different types, like total utility (overall satisfaction) and marginal utility (satisfaction from one additional unit). This happens because of the marginal rate of substitution that gets diminished. The indifference curve will neither touch nor will they intersect each other. Two points of the indifference curve do not give the same satisfaction level.
TU increases with an increase in the consumption of a commodity and as long as MU is positive. Till 4 burgers, TU increases at a diminishing rate as MU from each successive burger diminishes. There is a direct relationship between total utility and marginal utility. Total utility is always based on marginal utility as a total utility (TU) is the summation of marginal utilities. The relationship between TU and MU can be explained with help of the following table. The given is the schedule which shows the relationship between total utility and marginal utility.
Total Utility, Marginal Utility, and their Relationship
On the basis of given schedule, MU curve and TU curve can be drawn, as shown in the following diagram. If customers want to buy one more unit of Item 1, they may only do so if they are willing to give up some quantity of another good. Any point within the area budget line is an attainable combination that a consumer can buy given his income and price of goods. Any point outside the area is a non-attainable combination, which the consumer cannot afford to buy. The relationship between TU and MU can be explained with the help of the following schedule and diagram. Utility maximising consumers would like to decrease the consumption when ______.
- Each of the combinations will offer the sale satisfaction level to the consumer.
- When there is a drop in the consumer’s income, it shifts the budget line to the left.
- The effects of price changes on the amount desired of an item are described in the form of a law known as the law of demand.
- If any unit of commodity consumed beyond the point of satiety, consumer experiences dissatisfaction.
It asserts that when the price of an item decreases, the amount required rises, and when the price of a commodity rises, the quantity demanded declines. In other words, if everything else remains constant, the price of a commodity and its quantity requested have an inverse relationship. Our notes will guide you through the essentials of this chapter, aligning with the CBSE Class 12 Economics Syllabus. They provide a clear explanation of theories and practical applications, ensuring you grasp the material effectively. Class 12 Economics Revision Notes are designed to simplify challenging ideas, helping students develop a strong understanding of microeconomics and feel more confident for their exams. The questions involved in Balbharati Solutions are essential questions that can be asked in the final exam.
- It is possible that there can be a parallel shift in the budget line.
- However, as long as MU remains positive, the Total Utility (TU) will increase.
- The change happens because of the change in the consumer’s income and a change in the goods’ prices.
- Consumers are the ones who make the majority of consumption decisions.
- Thus, the consumer gets maximum satisfaction when MU is zero and that point is known as the point of saturation.
They help in understanding consumer preferences and how consumers choose between different combinations of goods. The indifference curve is a simple curve that shows the different combinations of two goods. Each of the combinations will offer the sale satisfaction level to the consumer. Movement along a demand curve occurs when changes in quantity sought are connected with variations in commodity price. According to the IC analysis, a buyer maximises his utility by selecting a package of two commodities that is also within his budget.
Explain the relationship between Total utility and Marginal utility. – Economics
For you, a commodity could be normal good, but for someone else, it might be inferior. The law of demand is founded on this principle, as the concept of reduced pricing is related to the Law of Diminishing Marginal Utility. MU of the commodity becomes negative when TU of a commodity is ______. When TU is at its maximum point, MU becomes zero; i.e., when the 5th burger is consumed. State with reasons whether you agree or disagree with the following statement.
Ultimately, when the consumption of a commodity is increased beyond the point of satiety, TU starts falling as MU becomes negative. It is considered to be measured in terms of cardinal numbers such as 1, 2, 3, 4, and so on. Thus, four utils are more significant than three utils, three utils are more significant than two utils, and so when mu is falling tu is on. All those goods and services which have the capacity to satisfy human wants are said to contain utility in the viewpoint of economics.
In the diagram, TU is the total utility curve and MU is the marginal utility curve. As the consumer consumes the first unit of commodity, s/he obtains 10 utils of utility. Total utility is the sum of all utilities derived by a consumer from all units of commodity consumed by him. Whereas, Marginal utility is the addition to the total utility derived by consuming an extra or additional unit of a commodity. In other words, marginal utility derived from the consumption of an additional or extra unit of a commodity.
When the indifference curve is high it shows a high satisfaction level. The marginal rate of substitution is the slope of the indifference curve. It is because of the MRS diminishing, that the indifference curve is convex in nature. As with increase in quantity of one good, the consumer forgoes less and less of the ther good. Consumers are the ones who make the majority of consumption decisions. A consumer is someone who buys goods and services to fulfil demands.
Although wealth and finance are frequently discussed in the book, it isn’t all about money. The budget constraint includes all the different combinations of goods or products that a person can afford based on the cost of goods and consumer income. The budget line is a graphical representation of all the bundles that cost the same as the consumer’s income. The budget line depicts two different combinations of goods that a consumer can buy based on his or her income and commodity prices. Consumers are prepared to spend lesser monetary amounts for more of a product as its utility falls with increased consumption. MU is the change in TU caused by the consumption of one extra unit.
