Market Interventions and Elasticity Quiz

#1

Which of the following is an example of a market intervention?

Price ceiling
Explanation

Government-imposed limit on how high a price can be charged for a product.

#2

What is the primary objective of market interventions?

To stabilize prices
Explanation

Interventions aim to prevent rapid price fluctuations.

#3

What is the primary goal of a price floor?

To prevent prices from falling below a certain level
Explanation

Sets a minimum price that can be charged for a product.

#4

Which of the following is an example of a government-imposed quota?

Production limit
Explanation

Restricts the quantity of a good that can be produced or sold.

#5

What is the primary goal of a subsidy in a market?

To incentivize producers
Explanation

Encourages increased production or consumption of a good.

#6

What does price elasticity of demand measure?

The responsiveness of quantity demanded to changes in price
Explanation

Percentage change in quantity demanded divided by percentage change in price.

#7

Which of the following statements is true regarding elastic demand?

Price changes have a proportionately larger effect on quantity demanded
Explanation

Small changes in price lead to large changes in quantity demanded.

#8

If the price elasticity of demand for a good is greater than 1, it is considered to be:

Elastic
Explanation

Demand is sensitive to price changes.

#9

What is the formula for calculating price elasticity of demand?

Percentage change in price / Percentage change in quantity demanded
Explanation

Formula measures the responsiveness of quantity demanded to price changes.

#10

Which of the following is an example of a price ceiling?

Rent control
Explanation

Government imposes a maximum rent that landlords can charge.

#11

If the cross-price elasticity of demand between two goods is negative, what can be concluded about their relationship?

They are complementary goods
Explanation

Consumers buy more of one good when the price of another decreases.

#12

What is the relationship between the price elasticity of supply and the slope of the supply curve?

They are inversely related
Explanation

Elastic supply curves are flatter; inelastic curves are steeper.

#13

If the income elasticity of demand for a good is negative, what can be inferred about the good?

It is an inferior good
Explanation

Demand decreases as income rises, indicating inferior good.

#14

Which of the following is a characteristic of perfectly elastic demand?

The demand curve is horizontal
Explanation

Consumers will only buy at one price, making demand curve flat.

#15

What is the formula for calculating income elasticity of demand?

Percentage change in quantity demanded / Percentage change in income
Explanation

Measures the responsiveness of quantity demanded to income changes.

#16

What happens to total revenue if demand is inelastic and the price decreases?

Total revenue increases
Explanation

Inelastic demand causes total revenue to increase when prices decrease.

#17

Which of the following is NOT a determinant of price elasticity of demand?

Income level of consumers
Explanation

Income level does not directly determine price elasticity of demand.

#18

If a good has perfectly inelastic demand, its price elasticity of demand is equal to:

0
Explanation

Quantity demanded remains constant regardless of price changes.

#19

Which of the following describes a situation where the demand for a good is highly price elastic?

The good has few substitutes available
Explanation

Consumers readily switch to alternatives when prices change.

#20

What effect does a tax imposed on producers have on the equilibrium price and quantity in the market?

Price increases, quantity decreases
Explanation

Tax shifts supply curve, leading to higher prices and lower quantity.

#21

What happens to consumer surplus if the price of a good decreases?

It increases
Explanation

Difference between what consumers are willing to pay and what they actually pay expands.

#22

What effect does a subsidy on a good have on consumer surplus?

It increases
Explanation

Subsidies lower prices, expanding consumer surplus.

#23

What is the main objective of a government-imposed quota in international trade?

To limit the quantity of imports
Explanation

Protects domestic industries by restricting foreign competition.

#24

In a market with perfectly elastic demand, what happens to total revenue when the price decreases?

Total revenue decreases
Explanation

Consumers buy the same quantity at lower prices, reducing total revenue.

#25

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

Consumer preferences
Explanation

Supply elasticity determined by factors such as production time, resource availability.
