MUxPx=MUyPy=MUmthe fraction with numerator cap M cap U sub x and denominator cap P sub x end-fraction equals the fraction with numerator cap M cap U sub y and denominator cap P sub y end-fraction equals cap M cap U sub m Reaching Equilibrium If
Condition 2: Law of DMU must operate (MU must fall as consumption increases).Condition 2: Law of DMU must operate (MU must fall as consumption increases). : The consumer gets more utility per rupee from . They will buy more consumption rises, MUxcap M cap U sub x falls until equality is restored. : The consumer gets more utility per rupee from . They will buy more until the ratios match again. 2. Ordinal Utility Approach (Indifference Curve Approach)
An indifference curve is a curve that shows different combinations of two goods that provide the consumer with the same level of total satisfaction. The consumer is indifferent between any of these combinations.
: The additional utility derived from consuming one more unit of a commodity. consumer equilibrium class 11 notes free
The utility approach had limitations, primarily the assumption of cardinal measurement of utility. To overcome this, economists J.R. Hicks and R.G.D. Allen developed the Indifference Curve Analysis, which uses an ordinal approach. In this approach, utility is not measured in numbers; consumers simply rank their preferences.
| Units | MU(_x) | MU(_x)/P(_x) | MU(_y) | MU(_y)/P(_y) | | :--- | :--- | :--- | :--- | :--- | | 1 | 20 | 10 | 24 | 6 | | 2 | 18 | 9 | 22 | 5.5 | | 3 | 16 | 8 | 20 | 5 | | 4 | 14 | 7 | 18 | 4.5 | | 5 | 12 | 6 | 16 | 4 |

This theory (developed by Hicks and Allen) argues that utility cannot be measured precisely. Instead, consumers can only rank their preferences (e.g., I prefer apples more than oranges). 3. Consumer Equilibrium in a Single-Commodity Case
Case B: Two Commodities Framework (Law of Equi-Marginal Utility) When spending income on two goods (
MRS is the rate at which a consumer is willing to substitute good without changing their total satisfaction level. : The consumer gets more utility per rupee from
Mastering the concept of is essential for students tackling Class 11 Economics. It forms the foundation for understanding how rational individuals make spending decisions to maximize their satisfaction.
The additional satisfaction gained from consuming one more unit of a good. Formula: B. The Law of Diminishing Marginal Utility (LDMU)
When MU reaches zero, TU reaches its maximum point (Point of Satiety). Phase 3: When MU becomes negative, TU starts declining.
