Market Equilibrium and Supply-Demand Dynamics Quiz

#1

What does the law of demand state?

As price decreases, demand increases
Explanation

Price and demand have an inverse relationship.

#2

What is a determinant of supply?

Technology
Explanation

Technological advancements impact production capabilities.

#3

What is the equilibrium price?

The price at which quantity supplied equals quantity demanded
Explanation

Market state where supply meets demand.

#4

What is a complementary good?

A good that is used in conjunction with another good
Explanation

Products consumed together, where demand for one influences the other.

#5

What is a surplus?

When quantity supplied exceeds quantity demanded
Explanation

Excess supply in the market.

#6

What is a price ceiling?

A government-imposed maximum price above which a good or service cannot be sold
Explanation

Regulation to prevent prices from rising above a set level.

#7

What is the relationship between price and quantity demanded on a demand curve?

Negative
Explanation

Inverse relationship: as price rises, quantity demanded decreases.

#8

What is the law of diminishing marginal utility?

As consumption increases, marginal utility decreases
Explanation

Additional satisfaction from consuming more of a good diminishes.

#9

What is the relationship between price and quantity supplied on a supply curve?

Positive
Explanation

Direct relationship: as price increases, quantity supplied increases.

#10

What is the law of increasing opportunity cost?

As production increases, the opportunity cost increases
Explanation

Allocating resources to produce more of one good increases the cost of producing another.

#11

What happens to market equilibrium if there is an increase in both demand and supply?

Equilibrium quantity increases, price is indeterminate
Explanation

Quantity supplied and demanded rise, affecting equilibrium quantity.

#12

What is price elasticity of demand?

The responsiveness of quantity demanded to changes in price
Explanation

Measure of consumer sensitivity to price changes.

#13

What is a price floor?

A government-imposed minimum price below which a good or service cannot be sold
Explanation

Regulatory measure to prevent prices from dropping below a certain level.

#14

What is the law of supply?

As price increases, supply increases
Explanation

Positive correlation between price and quantity supplied.

#15

Which factor does NOT typically cause a shift in the supply curve?

Changes in consumer preferences
Explanation

Supply curve shifts due to production-related factors, not consumer taste changes.

#16

What is the income elasticity of demand for normal goods?

Positive
Explanation

Normal goods have positive income elasticity, meaning demand increases with income.

#17

What is the price elasticity of demand for a perfectly inelastic good?

Equal to zero
Explanation

Quantity demanded remains constant despite price changes.

#18

What does a shift to the left in the demand curve indicate?

Decrease in demand
Explanation

Reduced demand across all price levels.

#19

What is the effect of a tax on a good in a market?

Decreases supply
Explanation

Tax imposes additional costs, reducing supply.

#20

What is the price elasticity of supply for a perfectly inelastic good?

Equal to zero
Explanation

Quantity supplied remains constant regardless of price changes.

#21

What does a shift to the right in the supply curve indicate?

Increase in supply
Explanation

Higher quantity supplied across all price levels.

#22

What is the effect of a subsidy on a good in a market?

Increases supply
Explanation

Subsidy reduces production costs, incentivizing higher supply.

#23

What is the difference between a movement along the demand curve and a shift of the demand curve?

A movement represents a change in quantity demanded at a specific price, while a shift represents a change in quantity demanded at all prices
Explanation

Movement along curve: Price change; Shift: Non-price factors affect demand.

#24

What is elasticity of supply?

The responsiveness of quantity supplied to changes in price
Explanation

How much producers adjust output in response to price changes.

#25

In the long run, a perfectly competitive market will adjust to changes in demand by:

Both adjusting quantity supplied and prices
Explanation

Market equilibrium achieved through price and output adjustments.
