- 1.Briefly state the basic characteristics of pure competition, pure monopoly, monopolistic competition, and oligopoly. Under which of these market classifications does each of the following most accurately fit? (a) a supermarket in your hometown; (b) the steel industry; (c) a Kansas wheat farm; (d) the commercial bank in which you or your family has an account; (e) the automobile industry. In each case, justify your classification. LO1arrow_forwardA firm in a purely competitive industry is currently producing 1,000 units per day at a total cost of $450. If the firm produced 800 units per day, its total cost would be $300, and if it produced 500 units per day, its total cost would be $275. What are the firm’s ATC per unit at these three levels of production? If every firm in this industry has the same cost structure, is the industry in long-run competitive equilibrium? From what you know about these firms’ cost structures, what is the highest possible price per unit that could exist as the market price in long-run equilibrium? If that price ends up being the market price and if the normal rate of profit is 10 percent, then how big will each firm’s accounting profit per unit be?arrow_forward4.

- Consider a set of 1000 companies operating in a competitive market. The supply curve for this market is given by O = 20+2P and the demand curve is given by D = 280-4P, where quantity Q is measured in millions of tons and Price P is measured in monetary units. Considering that the marginal cost of the individual firm is given by 2Q, the quantity Q being measured in thousands of tons, we ask: a) Sketch the market equilibrium and the equilibrium of an individual firm. b) What is the situation of this market at that particular moment. c) Make considerations about the long-run equilibrium trend of this market.arrow_forward(Last Word) Starbucks should continue to add stores in a city Multiple Choice a. as long as the marginal benefit of opening a new location does not fall below the marginal cost. b. as long as the marginal cost of opening a new location does not fall below the marginal benefit. c. until all remaining competing coffee stores have left the market. d. as long as the gap between marginal benefits and marginal costs is growing.arrow_forwardSuppose you are a perfectly competitive firm producing computer memory chips. Your production capacityis 1000 units per year. Your marginal cost is $10 per chip up to capacity. You have a fixed cost of $10,000 ifproduction is positive and $0 if you shut down. What are your profit-maximizing levels of production andprofit if the market price is ( a ) $5 per chip, ( b ) $15 per chip, and ( c ) $25 per chip?

- 2. Assume now that the costs of shipping are so large that Australian consumers can buy hand sanitizers from only one designated seller in Australia through both eBay and Amazon and there is no possibility of buying hand sanitizers in person in retail stores or any other online platforms. Explain with the help of a diagram whether this seller would be making a profit or a loss in the short run and in the long-run. Since it is one designated seller selling on two online market platforms (eBay and Amazon) would this be a monopoly or duopoly?arrow_forwardTeletronics reported record profits of $100,000 last year and is on track to exceed those profits this year. Teletronics competes in a very competitive market where many of the firms are merging in an attempt to gain competitive advantages. Currently, the company’s top manager is compensated with a fixed salary that does not include any performance bonuses. Explain why this manager might nonetheless have a strong incentive to maximize the firm’s profits. (LO4, LO5)arrow_forward5. (a) Assume that two firms A and B are in different industries (like computer software and computer hardware). What impact will a merger between these two firms have on the number of firms in each industry after the merger? Please give an explanation. (b) Current automobile companies are facing a shortage of computers chips used in cars to run various parts of the car, and therefore supply of cars has decreased since a necessary part(s) is not available. If an auto company like General Motors (GM) decided to buy a chip manufacturing company to ensure that it did not face a chip shortage in the future, would such a purchase lead to more concentration in either the auto industry or the chip-manufacturing industry?
