B) B

C) C

D) D

E) E

72) If both the supply and demand curves shift simultaneously, we can always predict what will happen to

A) both the price and the quantity.

B) either the price or the quantity, but not both.

C) only the price.

D) only the quantity.

E) neither the price nor the quantity.

73) A competitive market is in equilibrium. Then there is an increase in demand and an increase in supply. The equilibrium price ________, and the equilibrium quantity ________.

A) rises; increases

B) perhaps changes but we can’t say if it rises, falls, or stays the same; does not change

C) falls; increases

D) perhaps changes but we can’t say if it rises, falls, or stays the same; increases

E) falls; perhaps changes but we can’t say if it increases, decreases, or stays the same

74) If the demand and supply both increase equally, then the equilibrium price ________ and the equilibrium quantity ________.

A) increases; increase

B) increases; does not change

C) does not change; increases

D) increases; decreases

E) decreases; does not change

75) Kiwis and strawberries are substitutes for consumers. An increase in the price of a kiwi coupled with an increase in the number of strawberry growers ________ the equilibrium price of a pound of strawberries and ________ the equilibrium quantity of strawberries.

A) raises; increases

B) probably changes, but more information is needed to determine if it rises or falls; increases

C) raises; probably changes, but more information is needed to determine if it increases or decreases

D) lowers; probably changes, but more information is needed to determine if it increases or decreases

E) lowers; increases

76) A competitive market is in equilibrium. Then there is a decrease in demand and a decrease in supply. The equilibrium price ________, and the equilibrium quantity ________.

A) rises; decreases

B) perhaps changes but we can’t say if it rises, falls, or stays the same; decreases

C) falls; increases

D) perhaps changes but we can’t say if it rises, falls, or stays the same; increases

E) rises; increases

77) If both supply and demand decrease by the same amount, the equilibrium price

A) does not change.

B) rises.

C) falls.

D) cannot be predicted.

E) None of the answers is correct because the price depends on what happens to the equilibrium quantity.

78) Both the demand for and supply of cars changes in France. You observe that the quantity of cars does not change but the price rises. Thus, which of the following occurred?

A) Demand and supply increased by an equal amount.

B) Demand and supply decreased by an equal amount.

C) Demand increased and supply decreased by an equal amount.

D) Demand decreased and supply increased by an equal amount.

E) Demand increased by a larger magnitude than supply decreased.

79) Suppose that the demand curve for desktop computers shifts rightward and at the same time the supply curve shifts leftward. Which of the following could have caused these shifts?

A) Desktop computers are a normal good and incomes increased, while more firms entered the market.

B) The price of a laptop computer, a substitute for desktop computers, fell and the cost of producing desktop computers decreased.

C) Consumers purchased more computers because of the Christmas season and the labor costs of producing desktop computers decreased.

D) Desktop computers are a normal good and incomes increased, while the labor costs of producing personal computers increased.

E) Desktop computers are a normal good and incomes decreased, while the labor costs of producing personal computers increased.

80) If the demand curve for desktop computers shifts rightward and at the same time the supply curve shifts leftward, then

A) the equilibrium price definitely rises.

B) the equilibrium price definitely falls.

C) the equilibrium price definitely remains the same.

D) More information is needed to determine the effect on the equilibrium price.

E) the equilibrium quantity definitely increases.
