By connecting the tops of these rectangles with a smooth line, we get the TU curve that peaks at point Q and then slowly declines. To draw the MU curve, we take marginal utility from column (3) of the table. The prices of the two goods are Rs 4 and Rs 5 respectively. 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.

- Any point outside the area is a non-attainable combination, which the consumer cannot afford to buy.
- When the consumer consumes 2nd unit of goods, TU increases to 18 utils from 10 utils and MU decreases to 8 utils.

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. 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. 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. There is a direct relationship between total utility and marginal utility.
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. Marginal Utility (MU) refers to additional utility on account of the consumption of an additional unit of a commodity. 6.Marginal Utility (MU) It refers to additional utility on account of the consumption of an additional unit of a commodity.
In the above table, there are three forms of marginal utility (MU) as positive, zero, and negative marginal utility. Up to 5 units of consumption, marginal utility (MU) is decreasing and remains positive. Until the marginal utility (MU) is positive, total utility (TU) surges/rises at a declining rate. 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. Movement along a demand curve occurs when changes in quantity sought when mu is falling tu is are connected with variations in commodity price.
Consumer’s Optimum Choice:
The capacity of a commodity to meet a need is its utility. 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. It is assumed that the different unit consumed should be identical in all respects and consumption should be continuous.
According to the IC analysis, a buyer maximises his utility by selecting a package of two commodities that is also within his budget. This will be used to calculate a commodity’s demand curve. The MU curve is represented by the increment in total utility shown as the shaded block for each unit in the figure. When the tops of these blocks are joined by a smooth line, we obtain the MU curve. So long as the TU curve is rising, the MU curve is falling.

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. It is the fundamental Law of Utility approach to consumer’s equilibrium. This law states that as more and more standard units of a commodity are continuously consumed, the Marginal Utility obtained from each successive unit goes on diminishing.
The two goods are equally priced at Rs 10 and the consumer’s income is Rs 40. The preferences of the consumer are known as monotonic preferences. This is where one bundle has more than the other of one good and not less of the other good in between two bundles.
Total Utility, Marginal Utility, and their Relationship
In this article we will discuss about the relationship between Total Utility and Marginal Utility.
When the consumer consumes the third apple, the total utility becomes 45 utils. Thus, marginal utility of the third apple is 10 utils (45—35). Shift in demand curve occurs when the price of a commodity remains unchanged however the quantity demanded changes due to other factors, allowing the curve to shift to one side. Movement in the demand curve occurs when a commodity experiences a change in both quantity demanded and price, leading the curve to move in a specific direction.
This law is also called as a ‘Fundamental Law of Satisfaction’ or ‘Fundamental Psychological Law’. The marginal utility can be defined as an extra utility drawn from an extra unit of a commodity. Hence, it is the change in total utility while consuming one more unit of commodity. In other words, it is the ratio of change in total utility with the change in units of a commodity (normally one unit). Marginal utility is the addition made to total utility by having an additional unit of the commodity.

The benefit of the Theory of Consumer Behaviour Class 12 notes PDF is that it lets you pick your area of weakness and keep revising it thoroughly to perform well in the exam. 1.Consumer The one who takes decisions about what to buy for the satisfaction of wants, both as an individual or as a member of a household, is called a consumer. With the help of the above schedule the relationship between MU and TU can be represented in the diagram. Ans.The wants satisfying power of a good is called utility.
When the former reaches the highest point Q1 the latter touches the X-axis at point С where the MU is zero. When the TU curve starts falling from Q onwards, the MU becomes negative from С onwards. Elasticity of demand is measured at any location by dividing the length of the lower segment of the demand curve by the length of the upper segment of the demand curve at that point. At the midpoint of any linear demand curve, the value of ed is unity.
