B) the equilibrium price of MP3 players will increase; the equilibrium quantity may increase or decrease.

C) the equilibrium price of MP3 players may increase or decrease; the equilibrium quantity will increase.

D) the equilibrium price of MP3 players will decrease; the equilibrium quantity may increase or decrease.

 

35) Assume that both the demand curve and the supply curve for MP3 players shift to the right but the supply curve shifts more than the demand curve. As a result

A) both the equilibrium price and quantity of MP3 players will decrease.

B) the equilibrium price of MP3 players will decrease; the equilibrium quantity will increase.

C) the equilibrium price of MP3 players may increase or decrease; the equilibrium quantity will decrease.

36) Assume that the demand curve for MP3 players shifts to the right and the supply curve for MP3 players shift to the left, but the supply curve shifts more than the demand curve. As a result

A) both the equilibrium price and quantity of MP3 players will decrease.

B) the equilibrium price of MP3 players will decrease; the equilibrium quantity will increase.

C) the equilibrium price of MP3 players may increase or decrease; the equilibrium quantity will decrease.

D) the equilibrium price of MP3 players will increase; the equilibrium quantity will decrease.

37) Assume that the demand curve for MP3 players shifts to the right and the supply curve for MP3 players shift to the left, but the supply curve shifts less than the demand curve. As a result

A) both the equilibrium price and quantity of MP3 players will decrease.

B) both the equilibrium price and quantity of MP3 players will increase.

C) the equilibrium price of MP3 players may increase or decrease; the equilibrium quantity will decrease.

38) “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.
