In perfect competition, cardinal result of the model was that there were no frugal gelt in the long run. In a monopoly, the planetary house typically earns a positive economic profit. Why is there this difference? The lack of barriers to launching will allow competitors to enter the market unil economic profit is zero. These strongs ar worth takers, and they cannot affect scathes because their lead curve is horizontal.(4 marks)2. Assume that a single firm in a pure war-ridden industry has a fixed cost of $6500 and variable costs as indicated in the table below.a. Calculate the TC, AFC, AVC, ATC, and MC columns for this firm.

At the market price of $12.50 per unit, the firms marginal cost curve crosses the marginal revenue curve at an product level of 1000 units. What is the firms current profit? What is likely to occur in this market and why?(4 marks) P=12.5TR=P*Q = 12.5 * 1000 = 12500TC=ATC*Q = 10 * 1000 = 10000Profit=TR-TC = 12500 10000 = +2500Profit is positive, but for absolutely competitive markets there will be no profits at all in the long-run, so in this markets new firms will entermarket attracted by profits thus increasing market summate and reducing equilibrium price till it reaches close to P=$10, consequently leading to zero economic profits in long-run. For set out price this firm will be pressed to reduce output a bit for new P=MR=MC equilibrium.4. a.Why would a firm in a perfectly competitive market always choose to set its price equal to the current market price? If a firm set its price below the current market price, what perfume would this have on the market? (4 marks) The assumptions of perfect competition that matter here are that in perfect competition 1 every firm is so refined compared to the market so as to have no effect on market price 2 everyone is aware of everybodys price. Now if you set a price lower than the market, you are only cutting your nose to spite your face since you would sell as much as a higher price. (Remember, how much you take a leak is determined by your MC and the output level you produce at is the minimum MC). Cutting the price to sell more also costs more to produce you are worse off.If you set a price higher than market, noone will b uy from you.Explain how a firm in a competitive market identifies the profit-maximizing level of production. When should the firm raise production, and when should the firm lower production?In a perfectly competitive market, all firms are assumed to be very small compared to the market.Now the price is set at the market level, and as a small firm you take it as given you couldnt sell at a higher price since null would buy from you. Now in the long run, you should be at the minimum point of your cost curve, ensuring you reserve just normal profits. The price is your MR and at the minimum point of your AC curve your MC cuts it MC=MR and AC=AR.If the market price is higher than this, new entrants will sniff the opportunity created by highly normal profits and the market supply curve shifts right/up, reducing price until there are no more super ormal profitsto be earned.If market price is lower, then firms are make losses, some exit and supply curve shifts left driving price up.In e quilibrium, each firm is producing at the minmum point of the AC, where MC=MR=P.Hence the firm temporarily raises production when Pmin AC and makes supernormal profits until new entrants drive price back down or lowers production temporarily when P
