What is Price Elasticity of Demand?
Price Elasticity of Demand (PED) measures how responsive the quantity demanded of a good is to changes in its price. It's a crucial concept in economics that helps businesses and policymakers understand consumer behavior and make informed decisions.
PED Formula:
PED = (% Change in Quantity Demanded) ÷ (% Change in Price)
Or: PED = ((Q₂-Q₁)/((Q₂+Q₁)/2)) ÷ ((P₂-P₁)/((P₂+P₁)/2))

Elasticity Categories & Interpretation
Elastic Demand
PED > 1
Consumers are very responsive to price changes. A small price increase leads to a large decrease in quantity demanded.
Examples: Luxury goods, restaurant meals, entertainment
Inelastic Demand
PED < 1
Consumers are not very responsive to price changes. Price increases have little effect on quantity demanded.
Examples: Gasoline, medicines, basic food items
Unitary Elastic
PED = 1
The percentage change in quantity demanded equals the percentage change in price. Revenue remains constant.
Examples: Many consumer goods at certain price points
Business Strategy Recommendations
For Elastic Products (PED > 1)
- Focus on competitive pricing strategies
- Invest in brand differentiation to reduce price sensitivity
- Use promotional pricing and discounts to increase sales volume
- Consider bundling products to increase perceived value
For Inelastic Products (PED < 1)
- Price increases can boost revenue without significant volume loss
- Focus on value-based pricing strategies
- Invest in quality improvements to justify higher prices
- Consider premium positioning and brand strengthening
General Pricing Strategies
- Regular elasticity analysis to understand market dynamics
- Segment markets based on price sensitivity
- Monitor competitor pricing and market conditions
- Test price changes in limited markets before full implementation
Real-World Examples
Elastic Products
Airline Tickets
PED ≈ -2.4
When airlines increase prices by 10%, demand typically decreases by 24%. This is why airlines use dynamic pricing and offer discounts to fill seats.
Restaurant Meals
PED ≈ -2.3
Dining out is highly elastic as consumers can easily cook at home. Restaurants often use promotional offers to attract price-sensitive customers.
Luxury Cars
PED ≈ -1.8
High-end vehicles are elastic as they're not necessities. Economic downturns significantly impact luxury car sales.
Inelastic Products
Gasoline
PED ≈ -0.25
Short-term demand for gasoline is highly inelastic as people need to drive. This allows for tax policies and explains why gas prices fluctuate significantly.
Prescription Drugs
PED ≈ -0.1 to -0.3
Essential medications have very low elasticity as patients need them regardless of price. This explains high pharmaceutical profit margins.
Basic Food Items
PED ≈ -0.5
Staple foods like bread and milk are relatively inelastic as they're necessities. However, specific brands can be more elastic.
Key Learning Points
Factors Affecting Elasticity
- Availability of substitutes: More substitutes = more elastic
- Necessity vs luxury: Necessities are less elastic
- Time period: Longer time = more elastic
- Income proportion: Larger % of income = more elastic
- Brand loyalty: Strong loyalty = less elastic
Applications in Economics
- Tax policy: Inelastic goods are easier to tax
- Pricing strategy: Determines optimal pricing approach
- Market regulation: Understanding consumer impact of policies
- Revenue optimization: Maximizing total revenue
- Competition analysis: Understanding market dynamics
