Price Elasticity of Supply
Law of Supply: If the price of a commodity increases, the supply usually goes up. But how much does supply change? That’s where elasticity of supply helps.
CISCE: Class 12
Definition: Elasticity of Supply
- "Elasticity of supply is defined as the percentage change in quantity supplied by percentage change in price." – Prof. Bilas
- "Elasticity of supply is the ratio of percentage change in 'quantity supplied over the percentage change in price." – Lipsey
CISCE: Class 12
Meaning of Elasticity of Supply
- Price elasticity of supply measures how much the quantity supplied changes when the price changes.
- It tells us if supply is sensitive or not to price changes.
- It shows the ratio between percentage change in supply and percentage change in price, not just the actual amounts.
CISCE: Class 12
Formula: Elasticity of Supply
\[e_s=\frac{\text{Proportionate Change in Quantity Supplied}}{\text{Proportionate Change in Price}}\]
Where:
- es: Elasticity of supply
- Δq: Change in quantity supplied
- ΔP: Change in price
- q: Original quantity supplied
- p: Original price
CISCE: Class 12
Types of Supply Elasticity
| Type | Description | What it Means |
|---|---|---|
| Elastic Supply | Supply changes more than price | Small price rise, bigger supply increase |
| Inelastic Supply | Supply changes less than price | Price rises, supply barely increases |
CISCE: Class 12
Distinction Between Contraction of Supply and Decrease in Supply
| Contraction of Supply | Decrease in Supply |
|---|---|
| Description | Quantity supplied falls at lower price |
| Reason | Due to fall in price of commodity |
| Supply Curve | Downward movement along same supply curve |
CISCE: Class 12
Real-Life Application
- Imagine a shopkeeper: If prices of sweets rise by 10%, and he brings out 20% more sweets to sell, his supply is highly elastic!
- If he only brings 3% more, his supply is inelastic.
CISCE: Class 12
Key Point Summary
- Price elasticity of supply shows how responsive supply is to price changes.
- “Contraction” happens when price falls, and supply moves down along the curve.
- “Decrease” happens due to other factors; the whole curve shifts left.
