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.
