Question 1

"Because apples and oranges are substitutes,an increase in the price of oranges will cause the demand for apples to increase.This initial shift in demand for apples results in a higher price for apples;this higher price will cause the demand curve for apples to shift to the right." Which of the following correctly comments on this statement?
A)The statement will be true if consumer tastes for apples and oranges do not change.
B)The statement is false because a change in the price of apples would not change the demand for apples.
C)The statement is false because oranges are inferior goods;apples are normal goods.
D)The statement is false because one cannot assume that apples and oranges are substitutes for all consumers.

Question 2

The demand for lobster is higher in the summer than in the spring.If the price of lobster is lower in summer than in spring then
A)the supply of lobster is lower in spring than in summer.
B)consumers' tastes for lobster are greater in spring than in summer.
C)there is a surplus of lobster in summer and a shortage of lobster in spring.
D)there are more substitutes for lobster in summer than there are in spring.

Accepted Answer

Since the demand for lobster is higher in summer than in spring, a lower price in summer would suggest that the supply of lobster is higher in summer than in spring, leading to a surplus and lower prices. Therefore, choice A is the best option.

Question 5

Which of the following would cause a decrease in the equilibrium price and an increase in the equilibrium quantity of salmon?
A)a decrease in demand and an increase in supply
B)an increase in supply
C)an increase in supply and an increase in demand greater than the increase in supply
D)a decrease in demand and a decrease in supply

Accepted Answer

An increase in supply would shift the supply curve to the right, causing a decrease in the equilibrium price and an increase in the equilibrium quantity. Option A would cause a decrease in both equilibrium price and quantity. Option C would cause an increase in both equilibrium price and quantity, but the increase in demand would need to be greater than the increase in supply for the price to rise. Option D would cause a decrease in both equilibrium price and quantity.

Question 6

The following appeared in a Florida newspaper a week after a hurricane hit the state."Floridians are relieved that the storm produced no fatalities but homeowners face weeks,if not months,of rebuilding.Matters are made worse by the soaring prices of plywood and other building materials that always follow in a hurricane's path.Complaints of profiteering and price gouging have not deterred firms from raising their prices by over 100 percent." Which of the following offers the best explanation for the price increases referred to in the article?

Question 9

Select the phrase that correctly completes the following statement."A positive change in technology caused an increase in the supply of flat-screen televisions.As a result ________."
A)the price of flat-screen televisions decreased and the demand for flat-screen televisions increased
B)the equilibrium quantity of flat-screen televisions decreased
C)the price of flat-screen televisions decreased and the quantity demanded of flat-screen televisions increased
D)the price of flat-screen televisions decreased.The lower price caused the supply of flat-screen televisions to decrease

Accepted Answer

An increase in the supply of flat-screen televisions would lead to a decrease in price and an increase in quantity demanded, according to the law of supply and demand. Choice A is incorrect because it suggests the demand also increased, which is not necessarily true. Choice B is incorrect because an increase in supply would cause an increase in equilibrium quantity, not a decrease. Choice D is incorrect because it suggests that the lower price caused a decrease in supply, which is the opposite of what was stated in the question.

Question 10

What would happen in the market for laser eye surgery if insurance companies started to cover a portion of the price of voluntary procedures?
A)Demand will increase,but this will not shift the supply curve.
B)Supply will increase,but this will not shift the demand curve.
C)Demand and supply will both increase.
D)Demand will increase and supply will decrease.

Accepted Answer

If insurance companies started to cover a portion of the price of voluntary procedures, the demand for laser eye surgery would increase as more people would have access to it. However, since it is a voluntary procedure, the supply curve is unlikely to shift. The increase in demand will only result in a higher equilibrium price and quantity, without affecting the supply curve.

Question 11

Question 12

If more insurance companies decide to cover part of the price of voluntary laser eye surgery and more doctors decide to enter the field of laser eye surgery,what will happen in the market for laser eye surgery as a result of these two factors?
A)Demand will increase,but these two factors will not shift the supply curve.
B)Supply will increase,but these two factors will not shift the demand curve.
C)Demand and supply will both increase.
D)Demand will increase and supply will decrease.

Accepted Answer

With more insurance companies covering part of the price of voluntary laser eye surgery, more people will be able to afford the procedure and therefore demand will increase. Additionally, with more doctors entering the field, supply will also increase. Therefore, both demand and supply will increase as a result of these two factors.

Question 13

Blu-ray players were introduced to the market in 2006,and new technology has allowed for the cost of manufacturing the players to decline significantly since the initial introduction.How did this change in technology affect the market for Blu-ray players?
A)The new technology caused an increase in the supply of Blu-ray players and a decrease in price of Blu-ray players.
B)The new technology caused an increase in the supply of Blu-ray players and an increase in price of Blu-ray players.
C)The new technology caused an decrease in the demand for Blu-ray players.
D)The new technology caused an increase in the quantity of Blu-ray players supplied.

Accepted Answer

The new technology caused a decrease in the cost of manufacturing Blu-ray players, which increased the supply of Blu-ray players. An increase in supply usually causes a decrease in price, so the price of Blu-ray players decreased. Therefore, choice A is the best answer. The information in the question does not suggest any changes in demand for Blu-ray players, so choice C is not correct. The question also did not mention any changes in consumer behavior or preferences that could affect demand, so choice D is not correct either.

Question 14

Which of the following statements is true?
A)An increase in demand causes a change in equilibrium price;the change in price does not cause a further change in demand or supply.
B)A decrease in supply causes equilibrium price to rise;the increase in price then results in a decrease in demand.
C)If both demand and supply increase there must be an increase in equilibrium price;equilibrium quantity may either increase or decrease.
D)If demand decreases and supply increases one cannot determine if equilibrium price will increase or decrease without knowing which change is greater.

Accepted Answer

According to the law of supply and demand, an increase in demand will cause an increase in price, given a constant supply. However, the change in price does not cause a further change in demand or supply. The statement in option A accurately reflects this principle. The other options are incorrect because they either misunderstand the relationship between supply and demand or present scenarios that are too ambiguous to make definitive statements about equilibrium price.

Question 17

"The price of compact fluorescent light bulbs fell because of improvements in production technology.As a result,the demand for incandescent light bulbs decreased.This caused the price of incandescent light bulbs to fall;as the price of incandescent light bulbs fell the demand for incandescent light bulbs decreased even further." Evaluate this statement.
A)The statement is false.A decrease in the price of compact fluorescent light bulbs would decrease the demand for incandescent light bulbs,but a decrease in the price of incandescent light bulbs would not cause the demand for incandescent light bulbs to decrease.
B)The statement is false because the demand for incandescent light bulbs would increase as the price of compact fluorescent light bulbs fell.
C)The statement is false because compact fluorescent light bulbs producers would not reduce their prices as a result of improvements in technology;doing so would reduce their profits.
D)The statement is false because it confuses the law of demand with the law of supply.

Accepted Answer

The statement is false because it suggests that a decrease in the price of incandescent light bulbs would decrease the demand for them, which is not true according to the law of demand. A decrease in price would typically increase the demand for a product, not decrease it.

Question 18

Question 19

All else equal,a shortage of display screens used in the manufacture of tablet computers would
A)shift the supply curve for tablet computers to the right.
B)shift the supply curve for tablet computers to the left.
C)shift the demand curve for tablet computers to the right.
D)shift the demand curve for tablet computers to the left.

Accepted Answer

A shortage of display screens used in the manufacture of tablet computers would increase the production cost and decrease the supply, leading to a shift in the supply curve for tablet computers to the left. This is because the manufacturers would have to pay more to obtain the limited number of display screens, causing them to produce fewer tablets at the same cost.

Question 20

A decrease in the equilibrium price for a product will result
A)when the quantity demanded for the product exceeds the quantity supplied.
B)when there is a decrease in supply and a decrease in demand for the product.
C)when there is an increase in supply and a decrease in demand for the product.
D)when there is a decrease in demand and a decrease in the number of firms producing the product.

Accepted Answer

A decrease in equilibrium price can occur if there is an increase in supply and a decrease in demand for the product. This would shift the supply curve to the right, leading to a lower equilibrium price, and shift the demand curve to the left, leading to a decrease in the equilibrium quantity.
