Questions
Suppose that the Gondwanaland chairman of production, who sets the governmental price floor for gosum berries, in an effort to assist the gosum berry producers to have a higher income, sets the price floor at $70 per barrel. In that particular year, the amount of gosum berries produced at the $70 price floor was 700 barrels per month. To support the price of gosum berries, the Chairman of Production’s Office had to purchase 400 barrels per month. The accompanying chart and diagram shows supply and demand curves illustrating the market for Gondwanaland gosum berries.
| Price | Quantity Supplied | Quantity Demanded |
| $120 | 1,200 | |
| $110 | 1,100 | |
| $100 | 1,000 | 0 |
| $90 | 900 | 100 |
| $80 | 800 | 200 |
| $70 | 700 | 300 |
| $60 | 600 | 400 |
| $50 | 500 | 500 |
| $40 | 400 | 600 |
| $30 | 300 | 700 |
| $20 | 200 | 800 |
| $10 | 100 | 900 |
| $0 | 0 | 1,000 |
The accompanying diagram shows supply and demand curves illustrating the market for Gondwanaland gosum berries. Utilizing this information, answer the following questions.
(Description: The diagram shows a graph with the Quantity along the horizontal axis and Price along the vertical axis. A blue downward sloping line, labeled “D” represents the Demand curve for the data in the accompanying chart. A red upward sloping line, labeled “S” represents the Supply curve for the data in the accompanying chart. The point where the two lines cross is labeled “E” and represents the Equilibrium Quantity and Price. A gray dotted line extends downward from the point labeled “E” to the horizontal axis and points to the quantity of 500. Another gray dotted line extends from the point labeled “E” and extends to the right to the vertical axis and points at the price of $50. A black line crosses the graph to the horizontal axis at a price of $70 and is labeled “Price Floor.” A red dashed line extends from the point where the black line crosses the red Supply curve and extends down to the horizontal axis and points to the quantity 700. A blue dashed line extends from the point where the black line crosses the blue demand curve and extends down to the horizontal axis, pointing to the quantity of 300.)
a. In the absence of a price floor, the maximum price that a few of the consumers are willing to pay is up to $100 per barrel of gosum berries. The market equilibrium (E) price is $50 per barrel. How much consumer surplus is created when there is no price floor? Show your calculations.
b. How much producer surplus is created when there is no price floor? Show your calculations.
c. What is the total surplus when there is no price floor? Show your calculations.
d. After the price floor is instituted, the legal minimum price that can be charged by suppliers is $70 per barrel. The maximum price that a few of the consumers are still willing to pay is $100 per barrel of gosum berries. With the price floor at $70 per barrel, consumers buy 300 barrels of gosum berries per month. How much consumer surplus is created with the price floor? Show your calculations.
e. After the price floor is instituted, the Chairman of Productions Office buys up any barrels of gosum berries that the producers are not able to sell. With the price floor, the producers sell 300 barrels per month to consumers, but the producers, at this high price floor, produce 700 barrels per month. How much producer surplus is created with the price floor? Show your calculations.
f. The Chairman of Production’s Office buys any barrels of gosum berries that the producers are not able to sell. With the price floor, the producers sell 300 barrels per month to consumers; but the producers, at this high price floor, produce 700 barrels per month. How much money does the chairman of production’s office spend on buying up gosum berries? Show your calculations.
g. The Emperor of Gondwanaland must collect taxes from the people to pay for the purchases of surplus gosum berries by the Chairman of Production’s Office. As a result, total surplus (producer plus consumer) is reduced by the amount the Chairman of Production’s Office spent on buying surplus gosum berries. Using your answers for problems d, e, and f above, what is the total surplus when there is a price floor? Show your calculations.
h. How does this compare to the total surplus without a price floor from question c above? Is it more, or less, and by how much?
