- A firm sells its product in a perfectly competitive market where other firms charge a price of $90 per unit. The firm’s total costs are C(Q) = 50 + 10Q + 2Q2. a. How much output should the firm produce in the short run? b. What price should the firm charge in the short run? c. What are the firm’s short-run profits? d. What adjustments should be anticipated in the long runSuppose that, in a perfectly competitive industry, every firm has total cost function TC(Q)= 5million +4Q+Q²/50,000. Demand is given by D(p) - 375,000(42-2p). (a) If the industry consists of five firms, with no possibility of entry or exit, how much does each firm produce in equilibrium? (b) What is the profit of each firm? (c) How would you answer to part (a) change if there would be a possibility of entry and/or exit? Provide a sketch of how one would solve for the equilibrium outcome.Start from a market with perfect competition. For a representative producer, the long-term marginal cost is given by LMC=9Q2−20Q+50LMC=9Q2−20Q+50 and the long-term total cost function is LTC=3Q3−10Q2+50QLTC=3Q3−10Q2+50Q Assume that the price on the market right now is SEK 50. a) How much profit or loss does the producer make in the initial situation? b) Describe in detail what will happen in the market and why c) What will the equilibrium price be? d) how much will our producer produce at market equilibrium?

In a perfectly competitive market, industry demand is given by Q = 1000 – 20P. The typical firm’s average cost is TC = 300 + Q2 /3, and marginal cost by MC = (2/3)Q. Suppose there are 10 identical firms in the market. What is the market supply? A. 30Q B. 40Q C. 15Q D. 5QSuppose that a perfectly competitive firm faces a market price of $7 per unit, and at this price the upward-sloping portion of the firm's marginal cost curve crosses its marginal revenue curveat an outpuut level of 1,400 units. If the firsm produces 1,400 units, it's average variable costs equal $6.50 per unit, and its average fixed costs equal $0.80 per unit. What is the firm's maximizing (or loss-minimizing output level? What is the amount of it's economic profits (or losses) at this output level?
- 66. In a perfectly competitive market, industry demand is given by Q = 1000 – 20P. The typical firm’s average cost is TC = 300 + Q2 /3, and marginal cost by MC = (2/3)Q. The firms supply curve in terms of P is: A. 3Q B. 1.5Q C. 2.5Q D. 0.67QA firm sells its product in a perfectly competitive market where other firms charge a price of $70 per unit. The firm estimates its total costs as C(Q) = 40 + 10Q + 2Q2. a. How much output should the firm produce in the short run? units b. What price should the firm charge in the short run? $ c. What are the firm’s short-run profits? $ d. What adjustments should be anticipated in the long run? multiple choice Exit will occur since these economic profits are too low. No firms will enter or exit at these profits. Entry will occur until economic profits shrink to zero.The table below shows the average cost (AC) for a purely competitive market. The average revenue (AR) is constant at RM5 per unit and the firm’s total fixed cost (TFC) is RM4. If the average revenue falls to RM3 per unit, calculate the firm’s new profit or loss at the equilibrium. Based on your answer, should the firm continue or stop the production? Justify.

(0) If the price is $75, how much does the firm supply? (d) Does the firm continue to supply this quantity in the short-run? (e) Suppose there exists a standard market demand function from consumers(downward slopping). Please provide a logical discussion about how the marketachieves short-run equilibrium.Refer to Figure 1 for questions 18-20.
