Question 1

When price is $5 per unit, quantity demanded is 12 units. When price is $6 per unit, quantity demanded is 8 units. The value of the absolute price elasticity of demand is approximately
A) 2.20.
B) 4.00.
C) 1.82.
D) 0.36.

Accepted Answer

The absolute price elasticity of demand is calculated using the formula: |Ed| = |(ΔQ / Q_avg) / (ΔP / P_avg)|, where ΔQ is the change in quantity demanded, ΔP is the change in price, Q_avg is the average quantity demanded, and P_avg is the average price. Here, ΔQ = 8 - 12 = -4, ΔP = 6 - 5 = 1, Q_avg = (12 + 8) / 2 = 10, and P_avg = (5 + 6) / 2 = 5.5. Plugging these into the formula gives |Ed| = |(-4 / 10) / (1 / 5.5)| = |(-0.4) / (0.1818)| ≈ 2.20.

Question 2

A value of the absolute price elasticity of demand equal to 0.5 indicates that
A) a 5 percent increase in price leads to a 10 percent decrease in quantity demanded.
B) a 10 percent increase in price leads to a 5 percent decrease in quantity demanded.
C) a 0.5 percent increase in price leads to a 1 percent decrease in quantity demanded.
D) a 1 percent increase in price leads to a 5 percent decrease in quantity demanded.

Accepted Answer

A value of the absolute price elasticity of demand equal to 0.5 indicates that a 10 percent increase in price leads to a 5 percent decrease in quantity demanded. This means that demand is relatively inelastic, as the change in price results in a smaller proportionate change in quantity demanded.

Question 3

A value of the absolute price elasticity of demand equal to 0.25 indicates that
A) a 10% decrease in price leads to a 4% increase in quantity demanded.
B) a 10% decrease in price leads to a 25% increase in quantity demanded.
C) a 1% decrease in price leads to a 2.5% increase in quantity demanded.
D) a 0.25% decrease in price leads to a 1% increase in quantity.

Accepted Answer

The absolute price elasticity of demand is defined as the percentage change in quantity demanded divided by the percentage change in price. A value of 0.25 means that for every 1% change in price, the quantity demanded changes by 0.25%. Therefore, a 10% decrease in price leads to a 2.5% increase in quantity demanded, which is closest to the 4% increase described in option A, considering the options provided.

Question 4

The actual value of the price elasticity of demand is always
A) positive because of the law of demand.
B) negative because of the law of demand.
C) positive because of diminishing marginal utility.
D) negative because percentages can only be negative.

Accepted Answer

The law of demand states that as the price of a good or service increases, the quantity demanded decreases. As a result, the price elasticity of demand is always negative. However, the negative sign is often ignored in the analysis and only the absolute value is considered. So, the price elasticity of demand can be expressed as a positive value, but the actual value is negative.

Question 5

The word best associated with price elasticity of demand is
A) relative.
B) total.
C) absolute.
D) unit.

Accepted Answer

Price elasticity of demand is a measure of how much the quantity demanded of a good responds to a change in the price of that good, expressed as a percentage change in quantity demanded divided by the percentage change in price, making it a relative measure.

The percentage change in quantity demanded is ((100 - 150) / ((100 + 150) / 2)) * 100 = -40%. The percentage change in price is ((20 - 15) / ((20 + 15) / 2)) * 100 = 28.57%. The elasticity is |-40% / 28.57%| = 1.4.

Question 16

The price elasticity of demand measures
A) the responsiveness of quantity demanded to a change in price.
B) the responsiveness of price to a change in competition.
C) the change in quantity demanded due to a change consumer income.
D) the change in price due to a change in demand.

Accepted Answer

Price elasticity of demand measures the responsiveness of quantity demanded to a change in price. It measures how much the quantity demanded changes when the price changes. If the demand is elastic, a small change in price results in a large change in quantity demanded, whereas if the demand is inelastic, a change in price has a smaller effect on quantity demanded. The formula for price elasticity of demand is (Percentage change in quantity demanded)/(Percentage change in price).
