Will a profit-maximizing firm in a competitive market ever produce a positive level of output in the range where the marginal cost is falling? Give an explanation.
The market for paperback detective novels is perfectly competitive. Market Demand is given by Q=393-7P. Market Supply is given by Q=3P-9.
Suppose 55 units are bought to the market. Consider the Marginal Cost of production for these 55 units. What is the maximum Marginal Cost of production of these 55 units? Enter a number only, do not include the $ sign.
Hint: 55 doesn't have to be the market quantity.
Firms in a perfectly competitive market are said to be “price takers”—that is, once the market determines an equilibrium price for the product, firms must accept this price. If you sell a product in a perfectly competitive market, but you are not happy with its price, would you raise the price, even by a cent?

- 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 eliminating profits.

- Homework Consider the 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.

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?
