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?

Accepted Answer

When the wages of seamstresses rise, the cost of producing women's clothing increases. This causes a decrease in the supply of women's clothing, as shown by the leftward shift of the supply curve in panel (b). As a result, the equilibrium price of women's clothing increases, as shown by the upward movement along the demand curve from point A to point B in panel (b). The equilibrium quantity of women's clothing decreases, as shown by the decrease in the horizontal axis value from Q1 to Q2. Panels (a), (c), and (d) do not accurately depict the effects of an increase in seamstresses' wages on the market for women's clothing.

Question 3

Question 4

Let D = demand,S = supply,P = equilibrium price,Q = equilibrium quantity.What happens in the market for tropical hardwood trees if the government restricts the amount of forest lands that can be logged?

Accepted Answer

If the government restricts the amount of forest lands that can be logged, the supply of tropical hardwood trees decreases, causing a shift to the left in the supply curve. This results in a higher equilibrium price (P) and a lower equilibrium quantity (Q). The demand for tropical hardwood trees is unlikely to be affected by the regulation, so there is no shift in the demand curve. Therefore, the best choice is B, which describes a decrease in supply (S), increase in price (P), and decrease in quantity (Q) without any change in demand (D).

Question 5

Assume that the hourly price for the services of tarot card readers has risen and sales of these services have also risen.One can conclude that

Accepted Answer

If the price for tarot card readers has risen and sales have also risen, it indicates that there has been an increase in demand for their services despite the higher price. This is in accordance with the law of demand, which states that as the price of a good or service increases, the quantity demanded will decrease. Therefore, option C is the best choice. Option A can be eliminated as the law of demand has not been violated. Option B is not necessarily true and there may not be an increase in the number of tarot card readers. Option D is speculative and cannot be confirmed based on the given information.

Question 6

Which of the following would cause both the equilibrium price and equilibrium quantity of cotton (assume that cotton is a normal good)to increase?

Accepted Answer

An increase in consumer income, assuming cotton is a normal good, would lead to an increase in demand. This increased demand shifts the demand curve to the right, resulting in a higher equilibrium price and quantity.

Question 7

Orange juice drinkers want to consume more orange juice at a lower price.Which of the following events would have this effect?

Accepted Answer

A decrease in the price of orange juice processing would lead to a lower cost of production for orange juice. This may result in a decrease in the price of orange juice, which would encourage orange juice drinkers to consume more orange juice at a lower price. Option B is unlikely to have a direct impact on the price of orange juice as it increases the cost of production. Option C suggests a decrease in demand due to a decrease in income, which is not what the question asks for. Option D is irrelevant as it does not affect the price of orange juice.

Question 8

Let D = demand,S = supply,P = equilibrium price,Q = equilibrium quantity.What happens in the market for walnuts if the Centre for Disease Control and Prevention announces that consuming half a cup of walnuts each week helps to lower bad levels of cholesterol?

Accepted Answer

The announcement by the Centre for Disease Control and Prevention will likely lead to an increase in demand for walnuts as consumers are made aware of the potential health benefits. This will result in an increase in demand (D), but there will be no change in supply (S). The increase in demand will cause the equilibrium price (P) and quantity (Q) to increase as well. Therefore, the correct answer is A.

Question 9

If the price of a product is above equilibrium,what forces it down?

Accepted Answer

The answer of If the price of a product is...

-Refer to Figure 3-7.Assume that...

Question 11

Assume that the price for swimming pool maintenance services has risen and sales of these services have fallen.One can conclude that

Accepted Answer

If the price for swimming pool maintenance services has risen, it implies that the suppliers are charging more for the service, which can result in a decrease in the supply of swimming pool maintenance services, as suppliers may not be able to provide as many services at the new higher price. Additionally, if sales have fallen, it suggests that there are fewer people willing to purchase these services at the new higher price. Therefore, the decrease in demand as well as the decrease in the supply of these services is contributing to the fall in sales. The law of supply is not being violated here, as an increase in price can lead to a decrease in supply. There is no evidence or indication to suggest that swimming pool maintenance services are becoming more technologically advanced, so option D can be ruled out.

Question 12

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

Accepted Answer

A decrease in demand and an increase in supply will cause a surplus of soft drinks in the market. In order to clear the surplus, suppliers will have to compete by lowering prices, leading to a decrease in the equilibrium price. The equilibrium quantity may increase or decrease, depending on the extent to which the decrease in demand outweighs the increase in supply.

Question 14

Which of the following would cause the equilibrium price of white bread to decrease and the equilibrium quantity of white bread to increase?

Accepted Answer

A decrease in the price of flour would decrease the production cost of white bread, leading to a decrease in its equilibrium price. As a result, the suppliers will produce more white bread and the equilibrium quantity of white bread will increase. None of the other options would cause a decrease in the equilibrium price of white bread and an increase in its equilibrium quantity.

Question 18

An increase in the demand for lobster due to changes in consumer tastes,accompanied by a decrease in the supply of lobster as a result of bad weather reducing the number of fishermen trapping lobster,will result in

Accepted Answer

An increase in demand raises the equilibrium price and quantity, while a decrease in supply raises the price but lowers the quantity. The net effect is an increase in price, but the change in quantity depends on the relative magnitudes of the shifts in demand and supply.
