Question 1

A decrease in the demand for soft drinks due to changes in consumer tastes,accompanied by an increase in the supply of soft drinks as a result of reductions in input prices,will result in
A)a decrease in the equilibrium quantity of soft drinks and no change in the equilibrium price.
B)a decrease in the equilibrium price of soft drinks and no change in the equilibrium quantity.
C)a decrease in the equilibrium price of soft drinks;the equilibrium quantity may increase or decrease.
D)an increase in the equilibrium quantity of soft drinks;the equilibrium price may increase or decrease.

Accepted Answer

A decrease in demand for soft drinks will shift the demand curve to the left, resulting in a lower equilibrium price and quantity. An increase in supply due to lower input prices will increase the quantity supplied but lower the price, due to the law of supply. Therefore, the equilibrium price of soft drinks will decrease, but the equilibrium quantity may increase or decrease depending on the magnitude of the shift in demand versus supply.

Question 2

Figure 3-7 
-Refer to Figure 3-7.Assume that the graphs in this figure represent the demand and supply curves for women's clothing.Which panel best describes what happens in this market when the wages of seamstresses rise?
A)Panel (a)
B)Panel (b)
C)Panel (c)
D)Panel (d)

Accepted Answer

In panel (b), the supply curve shifts to the left due to an increase in the cost of production (i.e. higher wages for seamstresses), resulting in a decrease in quantity supplied and an increase in price. This reflects the market adjustment that occurs when the cost of producing women's clothing goes up, making it more expensive for firms to produce and limiting the quantity that can be supplied at any given price level.

Question 8

Figure 3-7 
-Refer to Figure 3-7.Assume that the graphs in this figure represent the demand and supply curves for tuna.Which panel best describes what happens in this market when there is a decrease in the productivity of commercial fishermen?
A)Panel (a)
B)Panel (b)
C)Panel (c)
D)Panel (d)

Accepted Answer

When there is a decrease in the productivity of commercial fishermen, the supply curve shifts to the left, as shown in panel (b) where the supply curve shifts from S1 to S2. This results in an increase in the equilibrium price (from P1 to P2) and a decrease in the equilibrium quantity (from Q1 to Q2). Panels (a) and (c) show scenarios of changes in demand, while panel (d) shows a scenario of government intervention.

Question 9

An article in the Wall Street Journal in early 2001 noted two developments in the market for laser eye surgery.The first development concerned side effects from the surgery,including blurred vision.The second development was that the companies renting eye-surgery machinery to doctors had reduced their charges.In the market for laser eye surgeries,these two developments
A)decreased demand and decreased supply,resulting in a decrease in the equilibrium quantity and an increase in the equilibrium price of laser eye surgeries.
B)decreased demand and increased supply resulting in an increase in both the equilibrium quantity and the equilibrium price of laser eye surgeries.
C)decreased demand and increased supply,resulting in a decrease in the equilibrium price and an uncertain effect on the equilibrium quantity of laser eye surgeries.
D)decreased demand and increased supply,resulting in a decrease in both the equilibrium price and the equilibrium quantity of laser eye surgeries.

Accepted Answer

The article mentions that there are two developments in the market for laser eye surgery. The first development is about the side effects of the surgery, which could decrease the demand for laser eye surgeries. The second development is about reduced charges for renting eye-surgery machinery to doctors, which could increase the supply of laser eye surgeries. Therefore, the market for laser eye surgeries is expected to experience a decrease in demand and an increase in supply, which will decrease the equilibrium price of laser eye surgeries. The effect on the equilibrium quantity of laser eye surgeries is uncertain because it depends on the extent to which the decrease in demand and the increase in supply offset each other.

Question 10

Figure 3-7 
-Refer to Figure 3-7.Assume that the graphs in this figure represent the demand and supply curves for used clothing,an inferior good.Which panel describes what happens in this market as a result of a decrease in income?
A)Panel (a)
B)Panel (b)
C)Panel (c)
D)Panel (d)

Accepted Answer

A decrease in income will shift the demand curve for inferior goods, such as used clothing, to the left. This will result in a decrease in equilibrium price and quantity, as shown in panel (c) where the demand curve shifts from D1 to D2 causing the price to drop from P1 to P2 and quantity to decrease from Q1 to Q2.

Question 11

Figure 3-7 
-Refer to Figure 3-7.Assume that the graphs in this figure represent the demand and supply curves for frozen yogurt.Which panel describes what happens in the market for frozen yogurt when the price of ice cream,a substitute product,increases?
A)Panel (a)
B)Panel (b)
C)Panel (c)
D)Panel (d)

Accepted Answer

Panel (c) illustrates an increase in demand for frozen yogurt, which would occur if the price of a substitute product like ice cream increases. This is because consumers would likely switch to frozen yogurt as ice cream becomes more expensive, shifting the demand curve for frozen yogurt to the right.

Question 19

An increase in input costs in the production of electric automobiles caused the price of electric automobiles to rise.Holding everything else constant,how would this affect the market for gasoline-powered automobiles (a substitute for electric automobiles)?
A)The supply of gasoline-powered automobiles would increase and the equilibrium price of gasoline-powered automobiles would decrease.
B)The demand for gasoline-powered automobiles would increase and the equilibrium price of gasoline-powered automobiles would increase.
C)The demand for gasoline-powered automobiles would decrease because consumers could afford to buy fewer gasoline-powered automobiles.
D)The demand for gasoline-powered automobiles would increase and the equilibrium price of gasoline-powered automobiles would decrease.

Accepted Answer

An increase in the price of electric automobiles would cause some consumers to switch to gasoline-powered automobiles as a substitute, increasing the demand for gasoline-powered automobiles. This would result in an increase in the equilibrium price of gasoline-powered automobiles.

Question 20

A)Panel (a)
B)Panel (b)
C)Panel (c)
D)Panel (d)

Accepted Answer

In anticipation of a price increase, buyers are likely to purchase more coffee now to avoid higher prices later, shifting the demand curve to the right, as depicted in Panel (c). This shift represents an increase in demand due to the expectation of future price increases.
