Elasticity of Demand
Elasticity of demand measures how responsive the quantity demanded of a good is to changes in its price or other influential factors.
Types of Elasticity of Demand:
- Price Elasticity of Demand: Measures how responsive the quantity demanded is to changes in the price of the good.
- Income Elasticity of Demand: Measures how responsive the quantity demanded is to changes in consumer income.
- Cross-Price Elasticity of Demand: Measures how responsive the quantity demanded of one good is to changes in the price of another good.
Factors Affecting Elasticity of Demand:
- Availability of substitutes: The more substitutes available, the more elastic the demand.
- Degree of necessity: The more necessary a good is, the less elastic the demand.
- Time: The longer the time period, the more elastic the demand.
- Proportion of income: The higher the proportion of income spent on the good, the more elastic the demand.
Interpreting Elasticity of Demand:
- Elastic demand (elasticity > 1): A small price change leads to a large change in quantity demanded.
- Inelastic demand (elasticity < 1): A small price change leads to a small change in quantity demanded.
- Unit elastic demand (elasticity = 1): A small price change leads to a proportionate change in quantity demanded.
Importance of Elasticity of Demand:
- Price setting: Understanding elasticity of demand helps firms set optimal prices.
- Revenue maximization: Firms can use elasticity of demand to maximize revenue.
- Policy making: Elasticity of demand is important in understanding the impact of government policies, such as taxes and subsidies.
Elasticity of Demand
- Measures the responsiveness of quantity demanded to changes in price or other influential factors.
Types of Elasticity of Demand
- Price Elasticity of Demand: Responsiveness of quantity demanded to changes in the price of the good.
- Income Elasticity of Demand: Responsiveness of quantity demanded to changes in consumer income.
- Cross-Price Elasticity of Demand: Responsiveness of quantity demanded of one good to changes in the price of another good.
Factors Affecting Elasticity of Demand
- Availability of substitutes: More substitutes available → more elastic demand.
- Degree of necessity: More necessary a good is → less elastic demand.
- Time: Longer time period → more elastic demand.
- Proportion of income: Higher proportion of income spent on the good → more elastic demand.
Interpreting Elasticity of Demand
- Elastic demand: Elasticity > 1, small price change → large change in quantity demanded.
- Inelastic demand: Elasticity < 1, small price change → small change in quantity demanded.
- Unit elastic demand: Elasticity = 1, small price change → proportionate change in quantity demanded.
Importance of Elasticity of Demand
- Price setting: Understanding elasticity of demand helps firms set optimal prices.
- Revenue maximization: Firms can use elasticity of demand to maximize revenue.
- Policy making: Elasticity of demand is important in understanding the impact of government policies, such as taxes and subsidies.
