Don't use chatgpt or any AI A profit-maximising firm in a competitive market is currently producing 1,000 units of output. It has average revenue of $50, average total cost of $40 and fixed cost of $10,000. a) What is its profit? b) What is its marginal cost? c) What is its average variable cost? Is the efficient scale of the firm more than, less than or exactly 1,000 units?
Suppose that each firm in a competitive industry has the following costs: Total cost: TC = 50 + q2 Marginal cost: MC = q where q is an individual firms quantity produced.

2. Two cereal firms that set prices and sell differentiated products propose to merge. Firm 1sells CrunchyCrunch for a price of $10 with a marginal cost of $6. Firm 2 sells FibryFibre for aprice of $12 and a marginal cost of $6.(a) When the price of CC rises, 20% of its lost demand goes to FF. What is the marginal costreduction for CC that is required to offset the upwards pricing pressure on the CC price?(b) You are employed as a consultant by the merging firms. You know that the DOJ knowsthat the marginal cost of FF will fall by 50 cents as a result of the merger, but that the agency isunsure of the diversion between FF and CC. How small will you need to claim that the diversionis in order for there to be no net upwards pricing pressure on the CC price?
Perfect competition is great for consumers, but not for producers. Present a perfect competition equilibriumusing the average cost and marginal cost curve framework used in class, and explain using words why thisequilibrium is good for consumers but not for firms. Then, assume the firm innovates in a way that gives thefirm market power and provides the firm with an economic profit. In a second diagram, show the situationfor this firm after the innovation. Use your results to explain using words why free market capitalism tendsto provide an improving living standard for consumers over time.
