Market Equilibrium and Shifts in Supply and Demand Quiz

#1

In the market equilibrium, what is true about the quantity demanded and the quantity supplied?

Quantity demanded equals quantity supplied
Explanation

Market equilibrium occurs when quantity demanded by consumers equals quantity supplied by producers.

#2

What is the law of demand?

As price increases, quantity demanded decreases
Explanation

Consumers demand less of a good as its price increases, ceteris paribus.

#3

If both supply and demand increase simultaneously, what will happen to the equilibrium quantity?

Remain unchanged
Explanation

Increase in both supply and demand keeps equilibrium quantity stable.

#4

What is the primary determinant of supply in a market?

Production technology
Explanation

The efficiency and technology of production determine the supply of goods.

#5

What is the concept of price elasticity of supply?

A measure of how much quantity supplied responds to a change in price
Explanation

Price elasticity of supply measures the responsiveness of quantity supplied to price changes.

#6

What happens to the equilibrium price and quantity when there is an increase in demand?

Price and quantity both increase
Explanation

Increase in demand shifts the demand curve right, causing price and quantity to rise.

#7

Which of the following factors can cause a shift in the supply curve?

Changes in production technology
Explanation

Improvements or changes in production methods can alter the supply of goods.

#8

What is the main determinant of demand in a market?

Consumer income
Explanation

Consumer income influences purchasing power and hence demand for goods.

#9

If the government imposes a tax on a good, how does it affect the equilibrium price and quantity?

Price increases, quantity decreases
Explanation

Tax raises the cost to consumers, reducing demand and thus equilibrium quantity while increasing price.

#10

If the market for a good is in disequilibrium, what can be expected to happen?

Price and quantity will adjust to reach equilibrium
Explanation

Market forces will push price and quantity towards equilibrium levels.

#11

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

Decreases price, but increases quantity
Explanation

Subsidy lowers costs for producers, reducing price while increasing quantity supplied.

#12

If the price of a good is above the equilibrium price, what is likely to happen?

Surplus of the good
Explanation

Excess supply results in a surplus of the good.

#13

What is the concept of elasticity of demand?

A measure of how much quantity demanded responds to a change in price
Explanation

Elasticity of demand measures the sensitivity of quantity demanded to changes in price.

#14

If the government imposes a price floor in a market, what is likely to happen?

Surplus of the good
Explanation

Price floor sets a minimum price above equilibrium, causing a surplus of the good.

#15

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

They are substitutes
Explanation

Positive cross-price elasticity suggests goods are substitutes, as an increase in one's price leads to increased demand for the other.

#16

What is the concept of a perfectly elastic demand curve?

Consumers are willing to buy any quantity at a given price
Explanation

Consumers will only buy at a specific price, regardless of quantity.

#17

What is the impact of a technological advancement in the production of a good on the market equilibrium?

Increases supply and decreases demand
Explanation

Technological advancement lowers production costs, increasing supply and reducing demand.

#18

What is the concept of deadweight loss in economics?

Total loss in economic welfare
Explanation

Deadweight loss represents the loss of economic efficiency due to market inefficiency.

#19

What is the primary factor influencing the elasticity of demand for a good?

Availability of substitutes
Explanation

The availability of substitutes influences how sensitive consumers are to price changes.
