#1
Which of the following describes price elasticity of demand?
A measure of how much the quantity demanded of a good responds to a change in price
The total revenue divided by the quantity of the good sold
The total revenue multiplied by the price of the good
The quantity demanded of a good divided by the price of the good
#2
In terms of consumer behavior, what does a negative cross-price elasticity indicate?
Complementary goods
Substitute goods
Normal goods
Inferior goods
#3
What does it mean if the price elasticity of demand for a good is greater than 1?
The good is a necessity
The good is a luxury
The demand for the good is elastic
The demand for the good is inelastic
#4
How does income elasticity of demand help to classify goods?
It indicates whether a good is a normal or inferior good
It measures the change in demand for a good relative to a change in income
It determines the price responsiveness of a good
It indicates whether a good is a substitute or complementary good
#5
What does a price elasticity of demand of 0.5 signify?
The demand for the good is elastic
The demand for the good is inelastic
The good is a luxury
The good is a necessity
#6
How does the availability of substitutes affect the price elasticity of demand?
Increases elasticity
Decreases elasticity
Has no effect on elasticity
Increases total revenue
#7
How does time affect the price elasticity of demand for a good?
Longer time frames generally result in more elastic demand
Longer time frames generally result in less elastic demand
Time has no effect on price elasticity
Shorter time frames generally result in more elastic demand
#8
What does it mean if the price elasticity of supply is greater than 1?
The supply is perfectly inelastic
The supply is inelastic
The supply is elastic
The supply is perfectly elastic
#9
Which of the following factors affects the price elasticity of supply?
The availability of substitutes
The time horizon
Consumer income
The number of producers
#10
What is the formula for calculating price elasticity of demand using the midpoint method?
((Q2 - Q1) / (Q2 + Q1)) / ((P2 - P1) / (P2 + P1))
((P2 - P1) / ((P2 + P1)/2)) / ((Q2 - Q1) / ((Q2 + Q1)/2))
((Q2 - Q1) / ((Q2 + Q1)/2)) / ((P2 - P1) / ((P2 + P1)/2))
((P2 - P1) / (P2 + P1)) / ((Q2 - Q1) / (Q2 + Q1))
#11
What is the relationship between price elasticity and total revenue?
As price elasticity increases, total revenue decreases
As price elasticity increases, total revenue increases
Price elasticity and total revenue are unrelated
Total revenue is always maximized at unit elasticity
#12
What is an example of a highly price elastic good?
Salt
Gasoline
Diamonds
Insulin
#13
How does the elasticity of supply differ in the short run and the long run?
Supply is more elastic in the short run
Supply is more elastic in the long run
Supply is equally elastic in both short and long runs
Supply is perfectly inelastic in both short and long runs
#14
What is an example of a product with perfectly elastic supply?
Rare antiques
Generic pharmaceuticals
Custom-built luxury cars
Commodity crops like wheat or corn
#15
What effect does a perfectly inelastic demand curve have on total revenue when prices change?
Total revenue increases when prices decrease
Total revenue decreases when prices decrease
Total revenue remains constant regardless of price changes
Total revenue decreases when prices increase
#16
Why might luxury goods have more elastic demand compared to necessities?
Consumers have more substitutes available for luxury goods
Consumers are less sensitive to price changes for luxury goods
Luxury goods tend to have lower income elasticities
Necessities are less responsive to price changes
