At that price, firms in this industry would Therefore, in the long run, firms would the copper market. Because you know that competitive firms earn economic profit in the long run, you know the long-run equilibrium price must be per pound. From the graph, you can see that this means there will be v firms operating in the copper industry in long-run equilibrium. PRICE (Dollars per pound)

7. Short-run supply and long-run equilibrium Consider the competitive market for copper. Assume that, regardless of how many firms are in the industry, every firm in the industry is identical and faces the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves shown on the following graph.
Suppose that the monthly market demand schedule for Frisbees is: Price $8 $7 $6 $5 $4 $3 $2 $1 Quantity Demanded 100 200 400 800 1,600 3,200 6,000 15,000 Suppose further that the marginal and average costs of Frisbee production for every competitive firm are Rate of Output 10 20 30 40 50 60 Marginal Cost $2.00 $3.00 $4.00 $5.00 $6.00 $7.00 Average Cost $2.00 $2.50 $3.00 $3.50 $4.00 $4.50 Finally, assume that the equilibrium market price is $5 per Frisbee. (a) How many Frisbees are being sold in equilibrium? (b) How many (identical) firms are initially producing Frisbees? (c) How much profit is the typical firm making? (d) In view of the profits being made, more firms will want to get into Frisbee production. In the long run, these new firms will shift the market supply curve to the right and push the price down to average total cost, thereby…
Consider the competitive market for ruthenium. Assume that no matter how many firms operate in the industry, every firm is identical and faces the same marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves plotted in the following graph. 80 72 56 · ཉི་ ཀ་ཇཱ་སྐ་ན་ COSTS (Dollars per pound) AVC 16 MC- 8 ATC B 12 16 20 24 28 QUANTITY (Thousands of pounds) 36 The following graph plots the market demand curve for ruthenium. ? Use the orange points (square symbol) to plot the initial short-run industry supply curve when there are 10 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 20 firms. Finally, use the green points (triangle symbol) to plot the short-run industry supply curve when there are 30 firms. PRICE (Dollars per pound) 80 72…

Use the orange points (square symbol) to plot the short-run industry supply curve for the wheat industry. Specifically, place an orange point at the lowest point of the supply curve and another orange point at the highest point of the supply curve. (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. Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.) 2.
