Suppose you are the manager of a watchmaking firm operating in a competitive market. Your cost of production is given by C= 300 + 29°, where q is the level of output and C is total cost. (The marginal cost of production, MC(q), is 4q; the fixed cost, FC, is $300). If the price of a watch is $80, how many watches should you produce to maximize profits? You should produce watches. (Enter your response as an integer.) What will the profit level be? Profit will be $ (Enter your response rounded to two decimal places.) At what minimum price will the firm produce a positive output? In the short run, the firm will produce if price is greater than $ per watch. (Enter your response as an integer.)
In the long-run equilibrium of a competitive market with identical firms, what are the relationships among price (P), marginal cost (MC), and average total cost (ATC)?
Question a) The average cost function of a competitive firm is AC= 5/Q+5+9*Q. The optimal quantity is: 10. How much is the profit? b) The average cost function of a competitive firm is AC= 3/Q +8 +9*Q The optimal quantity is: 3 How much is the profit? c) The marginal utility of x is 100-5x, and that of y is 200- 6y. The price of x is 1, the price of y is 2, the income of the consumer is 100. How many of y is there in the optimal basket?
A catering company producing fruit ice, in the Tandy school, has a production function q = 10min(k,l), where k is capital and 1 is labor. a. 15% If v = 81000 and w = 500 and P = 8600, where v, w, and P are as per the lecture notes, how many units of fruit ice will be produced and how much profit will be obtained? b. 10% Draw the supply curve for this catering company.
What happens to a competitive firm whose cost function exhibits decreasing marginal cost everywhere? Construct a concrete cost function of this type and carry out the search for the profit-maximizing output.
a) Find the long run equilibrium price. Find the minimum efficient scale of the typical firm. Find the typical firm’s average cost when it operates at minimum efficient scale. In the long run, what price will prevail in this market? In words, clearly justify your answer. Suppose demand is QD = 3,200 – 100P. (b) Explain why you expect the number of firms in this market to be fifty-five. In this market, what is the short run supply function of the typical firm? What is the short run market supply function? Suppose the local government introduced a $90 licensing fee that raised the fixed cost from $160 to $250. c) Would the introduction of the licensing fee affect the short run equilibrium price or quantity? Justify your answer? Clearly explain why you expect that in the long run fewer larger firms will operate in this market. After the introduction of the licensing fee, what is the new long run equilibrium price? How many firms will survive in this market?
Suppose that there are 90 firms in a market, each with the following cost function: C(q) = 65+4q2. Suppose the market demand is D(p) = 1,260 - 39p How much profit does each firm make in the short-run equilibrium? Your Answer:
A firm's profit function is T(q) = R(q) – C(q) = 40q – (35 + 20q + - 10q²). What is the positive output level that maximizes the firm's profit (or minimizes its loss)? What is the firm's revenue, variable cost, and profit? Should it operate or shut down in the short run? The output level at which the firm's profit is maximized is q =. (Enter your response as a whole number.) At this level of output, the firm's revenue (R) is $ (Enter your response as a whole number.) At the profit-maximizing level of output, the firm's variable cost (VC) is $ - (Enter your response as a whole number.) Profit (T) is $ (Enter your response as a whole number and include a minus sign if necessary.) The firm should produce in the short run.
