F. Highgarden was the seat of House Tyrell and is the regional capital of the Reach, which is the most
fertile part of Westeros, supplying the rest of the realm (especially King's Landing) with grain, fruit, wine,
and livestock. Such large-scale agriculture industry has led to a competitive fertilizer market. Suppose
the market for fertilizer in the Reach is perfectly competitive. Firms in the market are producing at their
profit-maximizing output but are currently incurring economic losses.
1. How does the price of fertilizer compare to the average total cost and the marginal cost of producing
fertilizer?
2. Draw two graphs, side by side, illustrating the present situation for the typical firm and for the
market as a whole.
3. Assuming there is no change in either demand or the firms' cost curves, how will the market adjust
in the long run? Explain what will happen in the long run to the price of fertilizer, marginal cost, average
total cost, the quantity supplied by each firm, and…

Use the orange points (square symbol) to plot the initial short-run industry supply curve when there are 20 firms in the market. (Hint: You can
disregard the portion of the supply curve that corresponds to prices where there is no output since this is the industry supply curve.) Next, use the
purple points (diamond symbol) to plot the short-run industry supply curve when there are 30 firms. Finally, use the green points (triangle symbol) to
plot the short-run industry supply curve when there are 40 firms.

Suppose the market of surgical mask in Country D is competitive.
а.
Assume the market of surgical mask in Country D operates at her long run
equilibrium. Draw side-by-side diagrams to show the long run equilibrium
conditions for a typical firm producing surgical masks and the market for surgical
masks. Label your diagrams clearly.
b.
Suppose a trade war happens and many other countries refuse to buy surgical masks
from Country D.
Making use of your diagram in (a), explain its short run effects on the equilibrium
price and quantity in the market of surgical masks in Country D, and the output and
the profit/loss of a typical firm producing surgical masks in Country D.

What effect might suppliers have on an industry? A. If many firms can supply an input comma then suppliers are like to have the bargaining power to limit a firm's profits. B. If suppliers are price takers, then a firm will likely be a price taker with no ability to raise price. C. If an input is specialized comma then the supplier is likely to have the bargaining power to limit a firm's profits. D.
