    Study Notes

    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.
