Elasticity of Demand measures the responsiveness of the quantity demanded of a good or service to changes in its price. It is quantified by the price elasticity of demand (PED), which indicates how much the quantity demanded changes in percentage terms when the price changes by 1%.
### Key Concepts:
- **Elastic Demand**: When the absolute value of price elasticity of demand is greater than 1. This means that a small change in price leads to a relatively larger change in the quantity demanded. Examples include luxury goods or commodities with readily available substitutes.
- **Inelastic Demand**: When the absolute value of price elasticity of demand is less than 1. This indicates that changes in price have a lesser effect on the quantity demanded. Essentials like gasoline and basic food items often exhibit inelastic demand.
### Factors Influencing Elasticity:
1. **Availability of Substitutes**:
- **Elastic**: If there are many close substitutes available, consumers can easily switch to alternatives when prices rise.
- **Inelastic**: If few or no substitutes are available, consumers have less flexibility to change their purchasing habits.
2. **Necessity vs. Luxury**:
- **Elastic**: Luxury items tend to have more elastic demand since they are nonessential.
- **Inelastic**: Necessities (e.g., basic food items, medications) often have inelastic demand because consumers need to purchase them regardless of price changes.
3. **Proportion of Income**:
- **Elastic**: Goods that take a large portion of a consumer's income (e.g., cars, houses) tend to have more elastic demand; consumers are more sensitive to price changes.
- **Inelastic**: Items that cost a small amount of income (e.g., gum, salt) are typically inelastic because price changes are not significant enough to impact purchasing behavior.
4. **Time Frame**:
- **Elastic**: Demand can be more elastic in the long run as consumers have time to adjust their behavior and find substitutes.
- **Inelastic**: In the short run, demand may be more inelastic as consumers cannot adjust their consumption habits quickly.
5. **Brand Loyalty**:
- **Elastic**: If consumers are not loyal to a brand and can switch easily, demand tends to be more elastic.
- **Inelastic**: Strong brand loyalty can make demand inelastic, as loyal customers are less sensitive to price changes.
Understanding these factors helps businesses and policymakers predict consumer behavior in response to price changes and make informed decisions about pricing, production, and taxation.
