6. Short-run supply and long-run equilibrium
Consider the perfectly competitive market for steel. 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.

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. 80 72 Supply (10 firms) 64 56 48 Demand Supply (20 firms) 40 32 Supply (30 firms) 24 16 8 120 240 360 480 600 720 840 960 1080 1200 QUANTITY (Thousands of pounds) If there were 10 firms in this market, the short-run equilibrium price of copper would be $ per pound.

- Which of the following statements in the full competitive market is correct? Choose an answer 1. The companies maximize their profit according to the rule «price equals average total costs». O 2. The companies maximize their profit according to the rule "marginal costs equal average total costs". 3. In the short term, the companies always make a profit. O 4. In the short-term market result, it always applies that the market price is above the average total costs. 5. In the long-term market result, the market price corresponds to the average total costs.arrow_forwardSuppose 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?
