#1
What is price elasticity of demand?
The measure of the responsiveness of quantity demanded to a change in price
ExplanationIt quantifies how much the quantity demanded changes in response to a change in price.
#2
If a 10% decrease in price leads to a 20% increase in quantity demanded, what is the price elasticity of demand?
2
ExplanationThe elasticity is calculated as the percentage change in quantity demanded divided by the percentage change in price.
#3
What is the price elasticity of supply?
The measure of the responsiveness of quantity supplied to a change in price
ExplanationIt gauges how much the quantity supplied changes in response to a change in price.
#4
Which of the following products is likely to have the most elastic demand?
Luxury cars
ExplanationLuxury cars typically have more elastic demand as consumers are more responsive to price changes for non-essential items.
#5
What does a price elasticity of demand of 0.5 indicate?
Inelastic demand
ExplanationAn elasticity less than 1 implies inelastic demand, meaning quantity demanded is less responsive to price changes.
#6
What is the formula to calculate price elasticity of demand?
Percentage change in quantity demanded / Percentage change in price
ExplanationThe formula expresses how much quantity demanded changes in response to a percentage change in price.
#7
If the price elasticity of demand for a product is -1.5, what does this imply?
The demand is relatively elastic
ExplanationThe negative sign indicates an inverse relationship, and the magnitude greater than 1 suggests relatively elastic demand.
#8
What does it mean if the price elasticity of demand is perfectly inelastic?
A change in price leads to no change in quantity demanded
ExplanationConsumers show no responsiveness to changes in price; quantity demanded remains constant regardless of price changes.
#9
Which of the following factors does NOT affect the price elasticity of demand?
Price of complementary goods
ExplanationThe price of complementary goods does not directly impact the responsiveness of quantity demanded to a change in price.
#10
If the price of a product increases by 10% and the quantity demanded decreases by 5%, what is the price elasticity of demand?
0.2
ExplanationElasticity is calculated as the percentage change in quantity demanded divided by the percentage change in price.
#11
If the cross-price elasticity of demand between two products is positive, what does it indicate about the products?
They are substitutes
ExplanationA positive cross-price elasticity suggests that an increase in the price of one product leads to an increase in demand for the other, indicating substitute goods.
#12
If a product has an income elasticity of demand of 0.8, what does this mean?
It is a normal good
ExplanationA positive income elasticity less than 1 implies a normal good, as an increase in income leads to a less than proportionate increase in quantity demanded.
#13
What is the relationship between price elasticity of demand and total revenue?
They have an inverse relationship
ExplanationAs price elasticity increases, total revenue moves in the opposite direction; when demand is elastic, lowering prices increases revenue.
#14
If the price elasticity of demand for a product is greater than 1, the demand is considered:
Elastic
ExplanationAn elasticity greater than 1 indicates elastic demand, meaning quantity demanded is responsive to price changes.
#15
Which of the following statements about perfectly elastic demand is true?
The demand curve is vertical
ExplanationIn perfectly elastic demand, consumers are willing to buy any quantity at a specific price, resulting in a vertical demand curve.
