The additional utility derived from the consumption of one more unit of a commodity. It is calculated as:
: The consumer gets more utility per rupee from Good X. They will buy more X and less Y. As consumption of X increases, MUxcap M cap U sub x falls until equality is restored. If consumer equilibrium class 11 notes free
The slope of the Indifference Curve must equal the slope of the Budget Line.
MUXPX=MUYPY=MUMthe fraction with numerator cap M cap U sub cap X and denominator cap P sub cap X end-fraction equals the fraction with numerator cap M cap U sub cap Y and denominator cap P sub cap Y end-fraction equals cap M cap U sub cap M MUcap M cap U must fall as more units are consumed. As consumption of X increases, MUxcap M cap
This law states that as a consumer consumes more and more units of a commodity, the marginal utility derived from each successive unit goes on declining. This is a fundamental assumption for reaching equilibrium. 3. Equilibrium in Single Commodity Case
Depending on the theory, utility is either measurable in numbers (Utils) or rankable (Preferences). 2. The Utility Approach (Cardinal Utility) This law states that as a consumer consumes
The units consumed must be identical in size, shape, and quality (e.g., a cup of water, not a spoonful).
Here are comprehensive Class 11 Economics notes on . These notes cover the syllabus generally prescribed by CBSE/State Boards (NCERT), focusing on both the Utility Analysis and Indifference Curve Analysis approaches.
