Study Notes
Price Elasticity of Demand
- When the price elasticity of demand is perfectly inelastic, it means that the quantity demanded does not change in response to a change in price.
Elasticity of Demand Curve
- A demand curve is considered elastic if a small price change leads to a large quantity change.
- A demand curve is considered inelastic if a large price change leads to a small quantity change.
Midpoint Formula
- The midpoint formula for price elasticity of demand helps solve the problem of averaging the two prices and quantities when calculating elasticity.
Price Elasticity Interpretation
- If the price elasticity of demand is less than one, demand is inelastic, meaning small price changes lead to small quantity changes.
- If the price elasticity of demand is greater than one, demand is elastic, meaning small price changes lead to large quantity changes.
- If the price elasticity of demand is equal to one, demand is unit-elastic, meaning small price changes lead to proportional quantity changes.
Elasticity Rule
- According to the elasticity rule, when two linear demand curves run through a common point, the steeper curve is more inelastic, and the flatter curve is more elastic.
Midpoint Method
- The midpoint method calculates changes in a variable compared to the average of the initial and final values.
Demand Curve Shapes
- A perfectly inelastic demand curve is a vertical line, indicating that quantity demanded does not change in response to price changes.
- A perfectly elastic demand curve is a horizontal line, indicating that a small price change leads to an infinite quantity change.
Total Revenue
- When demand is elastic, a price increase leads to a decrease in total revenue.
- When demand is inelastic, a price increase leads to an increase in total revenue.
Importance of Elasticity
- Elasticity allows us to analyze the responsiveness of demand and supply to changes in price and other factors with greater precision.
- It matters whether demand is unit-elastic, inelastic, or elastic because it affects how businesses and policymakers make decisions about pricing and production.
