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?

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]
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 there are 500 identicsl competitivd firms producing widgets and assume the total cost curve for each firm is given as, TC= 5q2+wq+10 and marginal cost is given as MC=10q + w where w is the widget maker's wage and q is the firm's output. If w=$50 what is the equation of the firms short run supply curve? 1) what is the average firm's profit (losses) at the new price of $61? 2) is the average firm in the short-run or long run? given it's profit(losses) should the firm continue to operate? 3) what would you predict, based on the perfectly competitive model of markets, will happen in this industry in the long run?
Suppose the short-run demand for a product is give byQD= 200−2P. Supposethe short-run supply curve isQD= 3P−50. (a) What is the market clearing, or competitive equilibrium price and quan-tity. (b) If the existing firms’ average total cost is 40, and the industry is a perfectlycompetitive, constant returns to scale industry, in the long run willpricerise or all? Explain.
The fact that a purely competitive firm’s totalrevenue curve is linear and upsloping to the right impliesthat: A. product price increases as outputincreases. B. product price decreases as outputincreases. C. product price is constant al all levels ofoutput. D. marginal revenue declines as more output isproduced.
2) Cost functionsConsider the following total cost function for an individual firm: C(q)= 10 +q + ¼ q^2 a- At what level of output is average cost at its lowest?b- Draw a graph showing firm average cost against quantity.c- Suppose that there is an industry with two identical firms, with this cost function. What is the industry total cost curve? What is the industry marginal cost curve?d- Suppose these two firms together act in a perfectly competitive manner. What is the price level in the case where these firms act perfectly competitively? What are the profits of the firms given perfectly competitive pricing?
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?
Consider the perfectly competitive market for steel. Assume that, regardless of how many firms are in the industry, every firm in the industry is identical and faces the marginal cost (MCMC), average total cost (ATCATC), and average variable cost (AVCAVC) curves shown on the following graph. The following diagram shows the market demand for steel. Use the orange points (square symbol) to plot the short-run industry supply curve when there are 10 firms in the market. (Hint: You can disregard the portion of the supply curve that corresponds to prices where there is no output since this is the industry supply curve.) Next, use the purple points (diamond symbol) to plot the short-run industry supply curve when there are 15 firms. Finally, use the green points (triangle symbol) to plot the short-run industry supply curve when there are 20 firms. If there were 20 firms in this market, the short-run equilibrium price of steel would be per ton. At that price, firms in this…
