Consider total cost and total revenue given in the following table: TABLE IN IMAGE Calculate profit for each quantity. How much should the firm produce to maximize profit?(ii) Calculate marginal revenue and marginal cost for each quantity. Graph them. (Hint: Put the points betweenwhole numbers. For example, the marginal cost between 2 and 3 should be graphed at 2½.) At what quantitydo these curves cross? How does this relate to your answer to part (a)?(iii) Can you tell whether this firm is in a competitive industry? If so, can you tell whether the industry is in along-run equilibrium? (8.75)
3. Suppose each firm's long run average cost curve, for positive levels of output, is given by AC = 0.1 + 0.05y + 5. The marginal cost curve is given by MC = 0.1 + 0.1y. (a) Find the level of output, for which the average cost is minimized. (b) What is the firm's minimum average cost? (c) Suppose you have many identical firms in a long run competitive equilibrium. Demand is p = 13.1 – 0.04Q. What is the market quantity? How many firms are there?
You are running a business in a perfectly competitive market. Your product sells for $5 and your marginal costs rise as output rises.(a) If the cost of producing another unit of output is $4, what should you do? What will happen to your profit?(b) If the cost incurred from your last unit of output produced is $6, what has happened to your profit? What should you do about this?(c) What general rule do the above examples suggest about how a firm should determine the level of output to produce so as to maximize profit?
