For a perfectly competitive firm, profit maximization doesnot conflict with resource allocative efficiency. Do you agree?Explain your answer.
The graph below shows the marginal cost (MC), average variable cost (AVC), and average total cost (ATC) curves for a firm in a
competitive market. These curves imply a short-run supply curve that has two distinct parts. One part, not shown, lies along the vertical
axis (quantity-0); this represents a condition of production shutdown. Where is the other part? Use the straight-line tool to drawit.

If the market price for this firm's product is $40, calculate the profit maximizing level of output for this firm using marginal analysis. It may help to create your own cost table and fill in columns for Marginal Cost and Average Total Cost based on the Total Cost information below. a.What is the level of profit for this firm at the profit maximizing output? b.To convince yourself that the quantity you found is indeed the profit maximizing quantity, try calculating what the profit would be at the next higher level of output.

- In the long run, perfectly competitive firms make zero economic profit. If this is the case, why does the firm even bother producing? Why not exit the market completely?arrow_forwardyou've been learning about what makes a market perfectly competitive, how a firm in a perfectly competitive market makes profit-maximizing decisions, and how a perfectly competitive market moves towards equilibirium. But how applicable is this to real life? For this discussion, try to think of a market (for a product or service) that is perfectly competitive or very close to it. What characteristics of the market make it like perfect competition? Are there factors that keep it from being perfectly competitive? If so, what are they? How close do you think the firms in this market are to perfectly competitive firms in choosing equilibrium price and quantity?arrow_forwardSuppose Larry runs a small business that manufactures shirts. Assume that the market for shirts is a price-taker market, and the market price is $10 per shirt. The following graph shows Larry's total cost curve. Use the blue points (circle symbol) to plot total revenue and the green points (triangle symbol) to plot profit for the first seven shirts that Larry produces, including zero shirts. 125 100 TOTAL COST AND REVENUE (Dollars) 25 ☐ Total Cost ☐ -50 0 1 2 3 4 5 6 7 8 QUANTITY (Shirts) Total Revenue A Profit (?)
