Study Notes
Elasticity of Demand
- Elasticity of demand measures how responsive the quantity demanded is to price changes.
- Higher elasticity indicates consumers are more responsive to price changes, while lower elasticity means less responsiveness.
Types of Elasticity
- Long Run Elasticity: The elasticity of demand is higher in the long run as consumers have more time to adjust their purchasing behaviors.
- Elastic Demand: An elasticity of 1.0 or greater signifies elastic demand, where significant changes in demand occur with price changes.
- Unit Elastic Demand: An elasticity of exactly 1.0 indicates unit elastic demand, where the percentage change in quantity demanded equals the percentage change in price.
- Inelastic Demand: An elasticity between 0 and 1.0 represents inelastic demand, where quantity demanded changes little in response to price changes.
Calculation of Elasticity
-
Formula for Elasticity:
- Percentage change in quantity demanded: [(QDemand(NEW) - QDemand(OLD)) / QDemand(OLD)]
- Percentage change in price: [(Price(NEW) - Price(OLD)) / Price(OLD)]
- Elasticity: Step 1 (Quantity) divided by Step 2 (Price)
Factors Affecting Elasticity
- The presence of many substitutes makes a good's demand elastic, as consumers can easily switch to alternatives, leading to decreased demand if prices rise.
- A good with no substitutes exhibits inelastic demand, meaning that price changes have minimal effect on quantity demanded.
Demand Curve Shifts
- A price increase of a complementary good (Good Y) shifts the demand curve of Good X to the left, indicating a decrease in demand for Good X.
- Conversely, an increase in the price of a substitute good (Good Y) causes the demand curve for Good X to shift to the right, indicating an increase in demand for Good X.
