- 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. The market demand curve for this product is Demand:QD = 120 P where P is the price and Q is the total quantity of the good. Currently, there are 9 firms in the market. a. What is each firms fixed cost? What is its variable cost? Give the equation for average total cost. b. Graph average-total-cost curve and the marginal-cost curve for q from 5 to 15.

In the long run with free entry and exit, what is the equilibrium price and quantity in this market? h. In this long-run equilibrium, how much does each firm produce? How many firms are in the market?The total revenue curve of a firm is R(q) = 40q − 12q2 and its average cost A(q) =1/30 q2 − 12.85q + 20 + 400/q, where q is the firm's output. i.

- A small firm operating in a purely competitive market has fixed costs of $45 per day compensates each employee $96 per day and has daily input and raw material costs as indicated in the table below. A. What would be the profit maximizing level of production if demand increased such that each unit sold for $130?, will the company make an economic profit producing this quantity of output? b: suppose the demand significantly decreased so that price for a unit of ouput sold to $115 each. What should the firm do? Why?a. Why is the marginal revenue of a perfectly competitive firm equal to the market price? b. Would a perfectly competitive firm produce if price were less than the minimum level of average variable cost? Why?The profit-maximizing quantity is the one at which the marginal revenue of the last unit was: O greater than the marginal cost. O less than the marginal cost. O equal to the marginal cost. O zero.
- Suppose 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?The total revenue curve of a firm is R(q) = 40q − 12q2 and its average cost A(q) = 1/30 q2 − 12.85q + 20 +400/q, where q is the firm's output. i. Derive an expression C(q) for the firm's total cost function.ii. Derive an expression Π(q) for the firm's profit function.iii. Is the rate of change of profit increasing or decreasing when theouput level of the firm is 10 units?iv. Determine the level of output for which the firm's profit is maximized.v. What is the firm's maximum profit?Please no written by hand solutions 7If SRTC 200+2q+4qwhere q is output, the firm's short-run supply function is a.P = 2 + 8q for P >= 2 and zero otherwise b. q = 0 P < 2; 0.125P - 0.25 P >= 2 c.P = 2 + 8a for p > 0 and zero otherwise. d.q = 0 P < 0; 0.125P - 0.25 P >= 0 8 Each firm in a perfectly competitive market has long-run average total cost represented as ATC+100/q. Long-run marginal cost is MC = 200q - 10 The market demand is O^ prime =215 dot 0 * 5P . At the long-run equilibrium price, how many firms are in the market? a= 500 b. n = 1000 c. n = 1200 d.n-2000 e.n = 2400
- a. Are the following statements true or false? Explain your reasons. For a firm with price in excess of average total cost, the presence of economic profits implies that the firm should increase output in the short run even if price is below marginal cost. If marginal cost is rising with increasing output, average cost must also be rising. Fixed cost is the same at each output level except when no output is produced. When a firm produces no output, there are no fixed costs. b. Allsmart’s demand curve is given by Q=10-P for its dishwashers. The marginal and average cost is $3 per dishwasher produced. Complete the following table.c) Assume that the market price for bagel services is 42 and store produces 30 units of the bagel. Calculate theprofit level. Is the store profit maximizing? Explain your answer. d) Go back to part c) and assume that there are 100 identical bagel store in the market. Determine the market supply curve. (You will obtain total market quantity, Q, as a function of price,P). Are elasticities of individual firm supply and market supply curves different? e) Given the market supply curve you have calculated in part d), now assume that market demand forhairdressers are given by Q=2900-50P. Find the equilibrium price and quantity in the market. Does the marketequilibrium correspond to long-run equilibrium? Explaina) 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?
