Meaning
Demand is the quantity of a commodity that a consumer is willing and able to buy at a given price during a given period of time.
Essentials of Demand
- Desire for the commodity
- Ability to pay
- Willingness to pay
- Given price
- Given period of time
2. Law of Demand
Statement
"Other things remaining constant (Ceteris Paribus), the quantity demanded of a commodity increases when its price falls and decreases when its price rises."
Assumptions
- Consumer's income remains constant.
- Prices of related goods remain unchanged.
- Consumer tastes and preferences remain constant.
- No change in future price expectations.
- Population remains unchanged.
Demand Schedule
| Price (₹/kg) | Quantity Demanded (kg) |
|---|---|
| 50 | 10 |
| 40 | 15 |
| 30 | 20 |
| 20 | 25 |
| 10 | 30 |
Observation: As price decreases, demand increases.
3. Demand Curve

Utility Theory
5. Utility
Meaning
Utility is the satisfaction obtained from consuming a good or service.
Types of Utility
- Total Utility (TU)
- Marginal Utility (MU)
6. Law of Diminishing Marginal Utility (DMU)
Statement
As a consumer consumes more and more units of the same commodity, the marginal utility from each additional unit decreases, while total utility increases at a diminishing rate.
Assumptions
- Homogeneous units
- Continuous consumption
- Rational consumer
- Constant income
- No change in tastes
Illustration
| Units Consumed | Total Utility (TU) | Marginal Utility (MU) |
|---|---|---|
| 1 | 10 | 10 |
| 2 | 18 | 8 |
| 3 | 24 | 6 |
| 4 | 28 | 4 |
| 5 | 30 | 2 |
| 6 | 30 | 0 |
Observation:
- Total Utility increases at a diminishing rate.
- Marginal Utility continuously decreases.
- Marginal Utility becomes zero when Total Utility is maximum.
7. Law of Equi-Marginal Utility
Statement
A consumer obtains maximum satisfaction by spending income on different goods in such a way that:
MU₁/P₁ = MU₂/P₂ = MU₃/P₃ = ...
Where:
- MU = Marginal Utility
- P = Price
Importance
- Helps consumers allocate income efficiently.
- Maximizes total satisfaction.
- Basis of rational consumer behavior.
8. Consumer's Equilibrium
Meaning
Consumer's equilibrium is the position where the consumer obtains maximum satisfaction with the given income and prices.
Conditions
- MU/P is equal for all commodities.
- Entire income is spent.
- Consumer behaves rationally.
9. Derivation of Demand Curve
The demand curve is derived from the Law of Diminishing Marginal Utility.
- As price decreases, consumers purchase more units.
- Quantity demanded increases.
- Therefore, the demand curve slopes downward.
10. Consumer Surplus
Meaning
Consumer surplus is the difference between the maximum price a consumer is willing to pay and the actual price paid.
Formula
Consumer Surplus = Total Utility − Total Amount Paid
Example
- Maximum willingness to pay = ₹100
- Actual price paid = ₹80
- Consumer Surplus = ₹20
Quick Revision
| Topic | Key Point |
|---|---|
| Demand | Willingness + Ability to Pay |
| Law of Demand | Price ↑ → Demand ↓ |
| Demand Curve | Downward sloping |
| Utility | Satisfaction |
| Total Utility | Total satisfaction |
| Marginal Utility | Extra satisfaction |
| Law of DMU | Marginal Utility decreases with consumption |
| Equi-Marginal Utility | MU/P is equal for all goods |
| Consumer Equilibrium | Maximum satisfaction |
| Consumer Surplus | Total Utility − Amount Paid |
Important Exam Points
- Demand requires both willingness and purchasing power.
- Law of Demand shows an inverse relationship between price and quantity demanded.
- Demand curve always slopes downward.
- Marginal Utility decreases as consumption increases.
- Consumer equilibrium occurs when MU/P is equal for all goods.
- Consumer Surplus = Total Utility − Amount Paid.
CHAPTER 5
Chapter 5: Elasticity of Demand
1. Meaning of Elasticity of Demand
Elasticity of demand measures the degree of responsiveness of quantity demanded due to a change in price, income, or the price of related goods.
2. Price Elasticity of Demand (PED)
Meaning
Price elasticity of demand measures the percentage change in quantity demanded resulting from a percentage change in price.
Formula
Price Elasticity (Ep) = % Change in Quantity Demanded ÷ % Change in Price
Types of Price Elasticity
(i) Perfectly Elastic Demand (Ep = ∞)
- A small change in price causes an infinite change in demand.
- Demand curve is horizontal.
(ii) Perfectly Inelastic Demand (Ep = 0)
- Demand remains unchanged despite changes in price.
- Demand curve is vertical.
(iii) Relatively Elastic Demand (Ep > 1)
- Percentage change in demand is greater than the percentage change in price.
(iv) Relatively Inelastic Demand (Ep < 1)
- Percentage change in demand is less than the percentage change in price.
(v) Unitary Elastic Demand (Ep = 1)
- Percentage change in demand equals the percentage change in price.
3. Measurement of Price Elasticity
(a) Percentage (Proportionate) Method
Ep = (% Change in Quantity Demanded) ÷ (% Change in Price)
(b) Total Expenditure (Outlay) Method
- If price falls and total expenditure increases → Elastic Demand (Ep > 1)
- If price falls and total expenditure decreases → Inelastic Demand (Ep < 1)
- If total expenditure remains unchanged → Unitary Elastic Demand (Ep = 1)
(c) Point Elasticity Method
Used to measure elasticity at a particular point on the demand curve.
Formula:
Ep = Lower Segment ÷ Upper Segment
(d) Arc Elasticity Method
Used to measure elasticity between two points on a demand curve.
4. Income Elasticity of Demand (Ey)
Meaning
Income elasticity measures the change in quantity demanded due to a change in consumer income.
Formula
Income Elasticity = % Change in Quantity Demanded ÷ % Change in Income
Types
- Ey > 1: Luxury Goods
- 0 < Ey < 1: Necessity Goods
- Ey = 0: No effect of income
- Ey < 0: Inferior Goods
5. Cross Elasticity of Demand (Exy)
Meaning
Cross elasticity measures the change in demand for one commodity due to a change in the price of another commodity.
Formula
Cross Elasticity = % Change in Quantity Demanded of Good X ÷ % Change in Price of Good Y
Types
Positive Cross Elasticity (Exy > 0)
Occurs for Substitute Goods.
Examples:
- Tea and Coffee
- Butter and Margarine
Negative Cross Elasticity (Exy < 0)
Occurs for Complementary Goods.
Examples:
- Car and Petrol
- Pen and Ink
Zero Cross Elasticity (Exy = 0)
Occurs when two goods are unrelated.
6. Factors Affecting Elasticity of Demand
- Availability of substitutes
- Nature of the commodity (necessity or luxury)
- Number of uses
