Part 1) For a perfectly competitive firm, its marginal cost curve above the minimum of average variable cost curve is the same as its short-run supply curve. A supply curve shows how much output a firm will produce at every possible price level. This is because in the short-run a firm will shut down if the price falls below the average variable cost. So, the portion of the marginal cost curve above the average variable cost curve is equivalent to the short run supply curve of the firm.
Part 2) We have the following information
Total cost: TC = 1200 + 7Q2
Demand equation: P = 60 – Q
For profit maximization we need to equate Price and the marginal cost (MC)
MC = ΔTC/ΔQ = 14Q
P = MC
60 – Q = 14Q
15Q = 60
Equilibrium quantity = 4

Suppose a perfectly Competitive firms minimum average variable cost is $1 when it produces 50. If the price is $2 and the firm's marginal cost is $2 the firm should Continue to produce, but produce less than 50 Continue to operate, but produce more than 50 Shut down Continue to produce 50 To maximize economic profit of perfectly competitive firm: will sell its goods below the market price all of the above will sell its goods above the market price...

The long-run supply curve for a perfectly competitive, constant-cost industry O is horizontal at minimum ATC. O is upward-sloping. O is horizontal at minimum AVC. O is found by adding up the marginal cost curves for all firms in the industry. As more firms enter the market: O the short-run market demand curve shifts to the left.

4. Deriving the short-run supply curve Consider the perfectly competitive market for dress shirts. The following graph shows the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves for a typical firm in the industry. that when the price is exactly equal to the average variable cost, the firm is indifferent between producing zero shirts and the profit-maximizing quantity. Also, indicate whether the firm will produce, shut down, or be indifferent between the two in the short run....
