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. At what quantity is average-total-cost curve at its minimum? What is marginal cost and average total cost at that quantity? c Give the equation for each firms supply curve. d. Give the equation for the market supply curve for the short run in which the number of firms is fixed. e. What is the equilibrium price and quantity for this market in the short run? f. In this equilibrium, how much does each firm produce? Calculate each firms profit or loss. Is there incentive for firms to enter or exit? g. 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?
If new technology in a perfectly competitive market brings about a substantial reduction in costs of production, how will this affect the market?
A computer company produces affordable, easy-to-use home computer systems and has fixed costs of 250. The marginal cost of producing computers is 700 for the first computer, 250 for the second, 300 for the third, 350 for the fourth, 430 for the fifth, 450 for the sixth, and 500 for the seventh. Create a table that shows the companys output, total cost, marginal cost, average cost, variable cost, and average variable cost. At what price is the zero-profit point? At what price is the shutdown point? If the company sells the computers for 500, is it making a profit or a loss? How big is the profit or loss? Sketch a graph with AC, MC, and AVG curves to illustrate your answer and show the profit or loss. If the firm sells the computers for 300, is it making a profit or a loss? How big is the profit or loss? Sketch a graph with AC, MC, and AVG curves to illustrate your answer and show the profit or loss.
Firms ill a perfectly competitive market are said to be price takers that is, once the market determines an equilibrium price for the product, firms must accept this price. If you sell a product in a perfectly competitive market, but you are not happy with its price, would you raise the price, even by a cent?
Return to Figure 9.2. Suppose P0 is 10 and P1 is 11. Suppose a new firm with the same LRAC curve as the incumbent tries to bleak into the market by selling 4,000 units of output. Estimate from the graph what the new firms average cost of producing output would be. If the incumbent continues. to produce 6,000 units, how much output would the two films supply to the market? Estimate what would happen to the market price as a result of the supply of both the incumbent firm and the new entrant. Approximately how much profit would each firm earn?

Why will profits for films in a perfectly competitive industry tend to vanish in the long run?
Since a perfectly competitive firm can sell as much as it wishes at the market price, why can the firm not simply increase its profits by selling an extremely high quantity?
Briefly explain the reason for the shape of a marginal revenue curve for a perfectly competitive firm.
Q23 Suppose a perfectly competitive firm is currently operating with the following information: Output = 1500 tonnesAverage total cost = $627 per tonneAverage variable cost = $614 per tonneMarginal revenue = $620 per tonneMarginal cost = $620 per tonneAt the current level of output, this firm is _____ profit and is an earning economic profit of _____. a. Maximising; -$10500. b. Not maximising; -$10500. c. Maximising; $10500. d. Maximising; $9000. e. Not maximising; -$9000.
Suppose a perfectly competitive firm is operating in short run. The information of MR, Q,ATC and AVC are 15 taka, 60 unit, 45taka and 35 taka respectively. Calculate firm’sprofit/loss and total fixed cost. From these calculations and based on all the giveninformation, can you conclude about the firm’s decision in short run? Explain your reasoningwith the help of a suitable diagram. Show all the relevant information in yourdiagram.[Q=profit maximizing output and MR=marginal revenue]

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
The market for fertilizer is perfectly competitive.Firms in the market are producing output but arecurrently incurring economic losses.a. How does the price of fertilizer compare to theaverage total cost, the average variable cost, andthe marginal cost of producing fertilizer?b. Draw two graphs, side by side, illustrating thepresent situation for the typical firm and for themarket.c. Assuming there is no change in either demand orthe firms’ cost curves, explain what will happenin the long run to the price of fertilizer, marginalcost, average total cost, the quantity supplied byeach firm, and the total quantity supplied to themarket.
