91) Studies have shown that drinking one glass of red wine per day may help prevent heart disease. Assume this is true, and a fungal disease destroys a large portion of the grape harvest of California vineyards. In the market for red wine, these two developments would
A) increase demand and increase supply, resulting in an increase in the equilibrium quantity and a decrease in the equilibrium price of red wine.
B) increase demand and decrease supply resulting in a decrease in both the equilibrium quantity and the equilibrium price of red wine.
C) increase demand and decrease supply, resulting in an increase in the equilibrium price and an uncertain effect on the equilibrium quantity of red wine.
D) increase demand and decrease supply, resulting in an increase in both the equilibrium price and the equilibrium quantity of red wine.

C) the equilibrium price of DVD players may increase or decrease; the equilibrium quantity will decrease.
D) the equilibrium price of DVD players will increase; the equilibrium quantity may increase or decrease.
97) Assume that both the demand curve and the supply curve for DVD 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 DVD players will decrease.
B) the equilibrium price of DVD players will decrease; the equilibrium quantity may increase or decrease.
C) the equilibrium price of DVD players may increase or decrease; the equilibrium quantity will increase.
D) the equilibrium price of DVD players will increase; the equilibrium quantity will decrease.
98) Assume that the demand curve for DVD players shifts to the left and the supply curve for DVD players shifts to the right, but the supply curve shifts more than the demand curve. As a result
A) both the equilibrium price and quantity of DVD players will decrease.
B) the equilibrium price of DVD players will decrease; the equilibrium quantity may increase or decrease.
C) the equilibrium price of DVD players may increase or decrease; the equilibrium quantity will increase.
D) the equilibrium price of DVD players will decrease; the equilibrium quantity will increase.
99) Assume that the demand curve for DVD players shifts to the left and the supply curve for DVD players shifts to the right, but the supply curve shifts less than the demand curve. As a result
A) both the equilibrium price and quantity of DVD players will decrease.
B) the equilibrium price of DVD players will decrease; the equilibrium quantity may increase or decrease.
C) the equilibrium price of DVD players may increase or decrease; the equilibrium quantity will increase.
D) the equilibrium price of DVD players will decrease; the equilibrium quantity will increase.
100) “The price of digital cameras fell because of improvements in production technology. As a result, the demand for non-digital cameras decreased. This caused the price of non-digital cameras to fall; as the price of non-digital cameras fell the demand for non-digital cameras decreased even further.” Evaluate this statement.
A) The statement is false because the demand for non-digital cameras would increase as the price of digital cameras fell.
B) The statement is false. A decrease in the price of digital cameras would decrease the demand for non-digital cameras, but a decrease in the price of non-digital cameras would not cause the demand for non-digital cameras to decrease.
C) The statement is false because it confuses the law of demand with the law of supply.
D) The statement is false because digital camera producers would not reduce their prices as a result of improvements in technology; doing so would reduce their profits.
