Elasticity of Demand Midpoint Method

What is the midpoint method in calculating elasticity of demand?

• A method to calculate the average elasticity between two points on a demand curve

• A method to calculate the elasticity at a single point on a demand curve

• A method to calculate the elasticity of supply

• A method to calculate the elasticity of income

Why is the midpoint method preferred over the simple percentage change method?

• It provides a more accurate measure of elasticity

• It is easier to calculate

• It is the only method available

• It is used only for supply elasticity

In the midpoint method, what is the formula for calculating the percentage change in quantity demanded?

• (Q2 - Q1) / ((Q2 + Q1) / 2)

• (Q2 - Q1) / Q1

• (Q2 + Q1) / 2

• (Q2 - Q1) / Q2

In the midpoint method, what is the formula for calculating the percentage change in price?

• (P2 - P1) / ((P2 + P1) / 2)

• (P2 - P1) / P1

• (P2 + P1) / 2

• (P2 - P1) / P2

What does a price elasticity of demand greater than 1 indicate?

• Demand is elastic

• Demand is inelastic

• Demand is unitary elastic

• Demand is perfectly inelastic

What does a price elasticity of demand less than 1 indicate?

• Demand is inelastic

• Demand is elastic

• Demand is unitary elastic

• Demand is perfectly elastic

What does a price elasticity of demand equal to 1 indicate?

• Demand is unitary elastic

• Demand is elastic

• Demand is inelastic

• Demand is perfectly elastic

If the price of a good increases from $10 to $12 and the quantity demanded decreases from 100 to 80, what is the elasticity of demand using the midpoint method?

• 1.22

• 0.82

• 1.5

• 0.5
