Consumer Demand and Elasticity Quiz

#1

Which of the following is an example of a necessity good?

Bottled water
Explanation

Necessity goods are essential for daily life.

#2

What does the price elasticity of demand measure?

The responsiveness of quantity demanded to changes in price
Explanation

It quantifies how demand reacts to price changes.

#3

What is the formula to calculate price elasticity of demand?

Percentage change in quantity demanded / Percentage change in price
Explanation

Measure of responsiveness of quantity demanded to price changes.

#4

Which of the following factors does NOT affect the price elasticity of demand?

Brand loyalty
Explanation

Brand loyalty doesn't directly influence demand's price sensitivity.

#5

What does it mean if the price elasticity of demand is greater than 1?

Demand is elastic
Explanation

Small price changes result in large quantity demanded changes.

#6

Which of the following is a characteristic of goods with elastic demand?

A small change in price leads to a large change in quantity demanded
Explanation

Price change causes significant quantity demanded change.

#7

What does it mean if the price elasticity of demand is less than 1 but greater than 0?

Demand is inelastic
Explanation

Quantity demanded changes less than proportionate to price change.

#8

Which of the following is true regarding goods with inelastic demand?

The demand curve is steep
Explanation

Small price changes lead to minor quantity demanded changes.

#9

Which of the following is a characteristic of goods with unitary elasticity?

Total revenue remains constant regardless of price changes
Explanation

Proportionate changes in price and quantity keep total revenue constant.

#10

What effect does an increase in consumer income have on the demand for inferior goods?

Decrease in demand
Explanation

As income rises, demand for inferior goods declines.

#11

If the price elasticity of demand for a product is perfectly elastic, what does it mean?

Consumers are highly responsive to price changes
Explanation

Consumers will buy infinite quantities if price decreases.

#12

What happens to total revenue when the price of a product decreases and demand is elastic?

Total revenue increases
Explanation

Price decrease leads to a proportionally larger increase in quantity sold.

#13

If the cross-price elasticity of demand between two goods is positive, what does it indicate?

The goods are substitutes
Explanation

Increase in price of one leads to an increase in demand for the other.

#14

What is the relationship between price elasticity of demand and total revenue when demand is inelastic?

They move in the same direction
Explanation

Price increase decreases quantity sold but revenue rises.

#15

What effect does a shift in the demand curve have on equilibrium price and quantity?

Both price and quantity increase
Explanation

Increase in demand leads to higher equilibrium price and quantity.

#16

When is the price elasticity of supply perfectly inelastic?

When quantity supplied is fixed regardless of price changes
Explanation

Supply doesn't change with price variations.

#17

What is the primary determinant of the cross-price elasticity of demand between two goods?

Price of the second good
Explanation

Measure of how demand for one good changes with price of another.

#18

How does a decrease in the price of a complementary good affect the demand for the main good?

Increases the demand for the main good
Explanation

Lower price of a complement encourages more consumption of the main good.

#19

Which of the following represents perfectly inelastic demand?

Ed = 0
Explanation

Quantity demanded remains constant regardless of price changes.

#20

What is the primary determinant of the price elasticity of supply for a good?

Cost of production
Explanation

Higher production costs usually lead to lower elasticity of supply.

#21

If the income elasticity of demand for a good is negative, what type of good is it?

Inferior good
Explanation

Demand decreases when consumer income rises.

#22

What is the primary determinant of the income elasticity of demand for a good?

Consumer income
Explanation

Measures how demand changes with consumer income.

#23

Which of the following factors is likely to increase the price elasticity of demand for a good?

Shorter time horizon
Explanation

Consumers have more time to adjust their purchasing decisions.

#24

When is the price elasticity of supply perfectly elastic?

When quantity supplied is infinitely responsive to changes in price
Explanation

Supply quantity adjusts infinitely with slight price changes.

#25

Which of the following goods is most likely to have an income elasticity of demand greater than 1?

Luxury cars
Explanation

Demand for luxury cars increases more than proportionately to income rise.
