ECONO 2202 CH 14 Key Terms/ Review ETC.
Barriers to entry
Anything that keeps new firms from entering an industry in which firms are earning economic profits. three most important barriers to entry in an oligopoly are economies of scale, ownership of a key input, and government barriers
Given the decision tree below, TruImage's profits are $1.5 million if the firm accepts Dell's contract offer of $20 per copy. Given the decision tree above, will Dell offer TruImage a contract of $20 per copy or a contract of $30 per copy?
$30
price leadership
A form of implicit collusion in which one firm in an oligopoly announces a price change and the other firms in the industry match the change.
Prisoner's Dilemma
A game in which pursuing dominant strategies results in noncooperation that leaves everyone worse off.
Cartel
A group of firms that collude by agreeing to restrict output to increase prices and profits. I.e. OPEC
Oligopoly
A market structure in which a small number of interdependent firms compete.
Nash Equilibrium
A situation in which each firm chooses the best strategy, given the strategies chosen by other firms.
Business Strategy
Actions that a firm takes to achieve a goal, such as maximizing profits.
Actions of firms that are aimed at deterring entry include A. setting lower prices to keep profits at a level that makes entry less attractive. B. introducing new products to fill market niches. C. advertising to create product loyalty. D. All of the above.
All of the above.
Collusion
An agreement among firms to charge the same price or otherwise not to compete.
cooperative equilibrium
An equilibrium in a game in which players cooperate to increase their mutual payoff.
noncooperative equilibrium
An equilibrium in a game in which players do not cooperate but pursue their own self-interest.
A duopoly game
An oligopoly consisting of only two firms is a duopoly. Each firm is known as a duopolist.
Why is the basic prisoner's dilemma story not always applicable to the real world?
Because it assumes the game will only be played once. In the real world, we play games more than once. Most business situations are repeated over and over. This is called a repeated game.
Competition from Substitute Goods or Services
Firms are always vulnerable to competitors introducing a new product that fills a consumer need better than their current product does
What are some key questions firms consider when pricing a good/ service?
How will different prices affect the likelihood that competitors enter the market? What is the minimum rate of return they must earn? What is competitors do enter the market?
terminal node
In a sequential game presented in extensive form, a final outcome point (node) showing the payouts to each player if the game ends at that point. (rates of return)
Consider a Caribbean cruise route served by two cruise lines, Carnival and Royal Caribbean. Both lines must choose whether to charge a high price ($280) or a low price ($270) to vacationers. These price strategies with corresponding profits are illustrated in the payoff matrix to the right. Carnival's profits are in red and Royal Caribbean's are in blue. Suppose the cruise lines decide to collude. At which outcome are joint profits maximized? Joint profits are maximized when Carnival picks $280 and Royal Caribbean picks $280. Is this outcome a Nash equilibrium? The cooperative equilibrium A. is not a Nash equilibrium because the game does not have an equilibrium. B. is a Nash equilibrium because joint profits are maximized. C. is not a Nash equilibrium because Carnival can increase its profit by picking the low price. D. is not a Nash equilibrium because both cruise lines can increase profits by picking the low price. Your answer is correct. E. is not a Nash equilibrium because Royal Caribbean can increase its profit by picking the low price.
Joint profits are maximized when Carnival picks $280 and Royal Caribbean picks $280. is not a Nash equilibrium because both cruise lines can increase profits by picking the low price.

economies of scale
The situation when a firm's long-run average costs fall as the firm increases output. This is the most important barrier to entry in an oligopoly
Under "early decision" college admission plans, students apply to a college in the fall and, if they are accepted, they must enroll in that college. Some critics of early decision plans, including some college presidents, argue that the plans put too much pressure on students to decide early in their senior year in high school which college to attend. Some college administrators have proposed abolishing early decision plans, but as a columnist in the New York Times noted, "It's more prevalent than ever, with some selective schools using it to fill upward of 40 percent of their incoming freshman class." Source: Frank Bruni, "The Plague of 'Early Decision,'" New York Times, December 21, 2016. Can game theory help analyze this situation? Game theoryLOADING... can help us analyze this situation as an example of what? A. The prisoner's dilemma. Your answer is correct. B. A cartel. C. A cooperative equilibrium. D. Collusion.
The prisoner's dilemma.
Suppose Securitex is a small firm that has developed a new anti-theft device for automobiles. Securitex currently sells its device online and earns profit of $18 million per year. GM is considering installing Securitex's system on its automobiles. The two firms first, however, must bargain over what price GM will pay Securitex for its software. GM chooses how much to offer Securitex for its system and then Securitex chooses whether to accept the offer and install its system on GM's automobiles. The strategies and corresponding profits for GM (GM) and Securitex (SX) are depicted in the decision tree to the right. Profits are in millions, and GM's payoffs represent the additional profit it can earn on its automobiles with Securitex's anti-theft system. What is the subgame-perfect equilibrium? A.

why is it difficult to determine an oligopoly's demand and marginal revenue curves?
because of how oligopoly firms make decisions. the decisions oligopoly firms make depends on how other oligopolies make decisions -> strategic interdependence. So we use game theory instead.
Competition From Existing Firms
(1) Competition among firms in an industry can lower prices and profits. (2) Competition in the form of advertising, better customer service, or longer warranties can also reduce profits by raising costs.
Why are the graphs used for analyzing perfect competition and monopolistic competition not helpful for analyzing oligopoly?
1) we need to use economic models that allow us to analyze more complex business strategies of large oligopoly firms i.e. more than just choosing the profit-maximizing price and output 2) We aren't able to draw the demand curves because we can't assume that price changes have no effect on the prices other firms in the industry charge. This is because firms in oligopolistic competition are large relative to their market
Five Competitive Forces Model
1. Competition from Substitute Goods or Services 2. Threat from Potential Entrants 3. Competition from existing firms 4. Bargaining power of suppliers 5. Bargaining power of buyers
three key characteristics for games
1. Rules that determine what actions are allowable In a business situation, rules are laws that a firm must obey and also factors outside of the firm's control (but only in the short run, i.e. production function.) 2. strategies that players employ to attain. their objectives in the game In a business situation, this is a business strategy i.e. maximizing profit 3. payoffs that are the results of the interactions among player's strategies In a business situation, the payoff is the profit a firm earns as a result of how its strategies interact with the strategies of other firms

flaws of concentration ratios
1. they do not include the goods and services foreign firms export to the U.S. 2. they are calculated for the national market, even though the competition in some industries, such as restaurants and college bookstores, is mainly local. 3. they do not account for competition that sometimes exists between firms in different industries. I.e. Walmart is included in the discount department store industry but also competes with firms in the supermarket and retail toy store industry
dominant strategy
A strategy that is the best for a firm, no matter what strategies other firms use.
payoff matrix
A table that shows the payoffs that each firm earns from every combination of strategies by the firms. This table is used to analyze oligopoly games
implicit collusion
A type of collusion in which multiple firms make the same pricing decisions even though they have not explicitly consulted with one another.

Nutco is a cashew-processing firm that operates in the developing country of Ecotopia. After procuring raw cashews from farms around the country, Nutco processes them using a labor-intensive method. The workers at Nutco recently demanded a 20 percent increase in their overtime wage rate. All members of Nutco's labor union, which was a substantial proportion of the company's labor force, went on an unannounced strike when the management only agreed to a 5 percent hike. During negotiations that followed, the management informed the union leader that this was a take-it-or-leave-it offer. The union leader was not convinced and declared that the workers would not come back to work unless their demands were fully met. Kurt Whitman, Nutco's human resources manager, however thinks that the strike will end soon because of the company's strong stand. Which of the following, if true, would suggest that the management's threat of not accepting the workers' demands is not credible? A. The production subsidies that Nutco receives as a part of the Ecotopian government's export promotion program were recently reduced. B. Due to the impact on production and the consequent delay in delivering export orders, several of Nutco's customers have indicated that they may cancel existing contracts. Your answer is correct. C. Nutco had accepted the labor union's demand for a higher number of sick leaves last year. D. Cashew-processing industries in other countries are relatively more capital-intensive. E. The demand for products like cashew wine and cashew brittle declined in spite of extensive promotion and advertising undertaken by the firms in this industry.

Eckerd Pharmacy will choose the large quantity and Walgreens Pharmacy will not enter.
The late Thomas McCraw, while a professor at the Harvard Business School, wrote: "Throughout American history, entrepreneurs have tried, sometimes desperately, to create big businesses out of naturally small-scale operations. It has not worked." Entrepreneurs hope to increase profitability by creating "big businesses." Unless there are significant economies of scaleLOADING..., they will not be successful. In the figure, firms producing at a level of output that is a small fraction of total industry sales, represented by LRAC1, have the lowest average costs for most levels of output. If a firm tries to grow to a larger size, such as that represented by LRAC2, its average costs will rise. Source: Thomas K. McCraw, ed., Creating Modern Capitalism, Cambridge, MA: Harvard University Press, 1997, p. 323. If an entrepreneur is planning on producing 5,000 units, should he choose the smaller or larger operation? A. The larger operation. B. The smaller operation. C. Either the smaller or larger operation.

Eleanor Alback is an equity research analyst working on a report on the semiconductor industry in the country Sillikon. The price of semiconductor chips is quite low. Since it is an important input in the production of personal computers, she feels that firms could increase prices without drastically affecting sales. However, it appears that none of the firms are interested in hiking the price of their product despite high demand. Lan Shih, who works at a government think-tank, attributes the low prices to intense price wars between the firms. Which of the following, if true, would weaken Lan's claim that price-war is the cause of low prices? A. The boom in the semiconductor industry led to productivity gains in many industries that use semiconductors. B. Although many firms in this industry own patents on their products, similar products are almost always introduced by a rival firm for a lower price. C. The skilled engineers that the industry hires are very well-paid. D. Existing firms in the semiconductor industry consciously target different market segments that are mutually exclusive. Your answer is correct. E. Some commentators feel that the growth in this industry can only be sustained with continuous innovation.
Existing firms in the semiconductor industry consciously target different market segments that are mutually exclusive.
Threat from Potential Entrants
Firms face competition from companies that currently are not in the market but might enter Existing firms will act to deter entry. Some actions include advertising to create product loyalty, introducing new products to fill market niches, and setting lower prices to keep profits at a level that makes entry less attractive for potential new entrants

Deterring Entry & Bargaining Between Firms
Firms use Sequential Games to analyze these two Business Strategies:
Coca-Cola and Pepsi both advertise aggressively, but would they be better off if they didn't? Their commercials are usually not designed to convey new information about their products. Instead, they are designed to capture each other's customers. The payoff matrix to the right illustrates the following information: ≻If neither firm advertises, Coca-Cola and Pepsi both earn profits of $750 million per year. ≻ If both firms advertise, Coca-Cola and Pepsi both earn profits of $500 million per year. ≻If Coca-Cola advertises and Pepsi doesn't, Coca-Cola earns profits of $900 million and Pepsi earns profits of $400 million. ≻If Pepsi advertises and Coca-Cola doesn't, Pepsi earns profits of $900 million and Coca-Cola earns profits of $400 million. If Coca-Cola wants to maximize profit, they will advertise. If Pepsi wants to maximize profit, they will advertise. Is there a Nash equilibrium? A. There is a Nash equilibrium in which Pepsi advertises and Coca-Cola does not advertise. B. There is only a Nash equilibrium in which both firms advertise. Your answer is correct. C. There is only a Nash equilibrium in which both firms do not advertise. D. There is a Nash equilibrium in which both firms advertise and one in which both firms do not advertise.

In June 2013, Microsoft announced that its new Xbox One video game console would have a price of $499. Sony then announced that its new PlayStation 4 video game console would have a price of $399. An article on the event where Microsoft introduced the new console noted that the Microsoft spokesman "started by showing off features like live-television technology and the ability to video-chat through its Skype service." The article goes on to say that not until nearly half way through the presentation did the Microsoft spokesman mention the new games the console could play. Source: Ian Sherr and Daisuke Wakabayashi, "Xbox One to Launch at $499, PlayStation 4 at $399," Wall Street Journal, June 10, 2013.

Michael Porter has argued that in many industries "strategiesLOADING... converge and competition becomes a series of races down identical paths that no one can win." Source: Michael E. Porter, "What Is Strategy?" Harvard Business Review, November-December 1996, p. 64. Are firms in these industries likely to earn economic profits?
No
When Apple first launched Apple Music, singer Taylor Swift refused to allow her album 1989, which had been the best selling album of 2014, to be made available for the service because Apple did not intend to pay royalties on songs it streamed during an initial three month period when the service would be free to subscribers. In response, Apple changed its policy and agreed to pay royalties during those three months even though doing so reduced its profit. Source: Mike Ayers and Ethan Smith, "Taylor Swift Is Now Making '1989' Available on Apple Music," Wall Street Journal, June 25, 2015. Do singers typically have substantial bargaining power with Apple, Spotify, and the other streaming services? A. Not unless they are top performers in the market. Your answer is correct. B. Only if they have a contract with the streaming services. C. Not unless they collude. D. Only if they get most of their revenue from the streaming services.

Erin Reinhardt and her friend Carol Newman have just arrived in the country Boloni for a summer holiday. While renting a car on their first day in Boloni they notice that the car rental rates are so much higher than rates back home. Carol says that in a matter of time, competition should drive prices down. Erin feels that the market for car rentals is probably competitive enough; it could just be high cost of operations in Boloni that are responsible for the high prices. Which of the following, if true, would weaken Erin's argument that high costs are responsible for high prices? A. Only 3 firms account for almost 88 percent of the car rental market. Your answer is correct. B. The car rental industry in Boloni is valued at $50 million. C. Most of the growth in the car rental industry comes from the high-value rentals of luxury cars. D. Most households in Boloni own at least one car. E. After global oil prices increased, the government of Boloni decided to ration the quantity of gasoline sold
Only 3 firms account for almost 88 percent of the car rental market.
Getchecked Inc. is a leading medical devices manufacturer. A cosmetic surgeon, Dr. Matt Breen is discussing the prices of Getchecked's medical devices with his colleague, Dr. Ed Walter. Matt says, "Getchecked probably finds it difficult to make profits. The medical device market is highly crowded." Ed replies, "Well, they do have quite a few patented products so the profits must be flowing in." Meanwhile James Radford, a medical technician, agrees that Getchecked must be doing well. Given that Getchecked's products are widely used in the market, even an increase in prices would not affect sales or profits according to James. Which of the following, if true, would weaken Matt's argument that Getchecked's profits are most likely negligible due to competition? A. Product differentiation in terms of quality is common in this market because the buyers are very quality-conscious. Your answer is correct. B. Doctors choose the brand of medical devices that should be used in the hospital. C. Lifestyle-related diseases like diabetes and hypertension are on the rise in this country. D. Some firms in the market have started manufacturing medical devices that can be directly used by the final consumer. E. Getchecked recently hiked the per-unit commission paid to its salesmen.

The demand for personal computers has been growing at a remarkable annual rate of 30 percent for the last five years. B. Although semiconductors are crucial to the production of personal computers, they form a small proportion of the total inputs used to produce personal computers. C. Since the semiconductor industry has high fixed costs, a low price charged by existing firms can keep new entrants out of the market. Your answer is correct. D. Investment in manufacturing facilities forms a substantial proportion of the fixed cost in this industry. E. With new advances in computing technology, the prices of personal computers have been falling in spite of high demand.
Since the semiconductor industry has high fixed costs, a low price charged by existing firms can keep new entrants out of the market.

Matt says, "Getchecked probably finds it difficult to make profits. The medical device market is highly crowded." Ed replies, "Well, they do have quite a few patented products so the profits must be flowing in." Meanwhile James Radford, a medical technician, agrees that Getchecked must be doing well. Given that Getchecked's products are widely used in the market, even an increase in prices would not affect sales or profits according to James. Which of the following, if true, would weaken Ed's claim that Getchecked's patents would ensure profits in this market? A. Getchecked entered the pharmaceutical industry last year and recently acquired a pharma company that owns several patents. B. The market for healthcare and medical devices in developing countries is projected to grow by 15 percent in the next five years. C. The sale of used medical equipment in the country is not regulated by the government. D. The Medical Administrative Authority in the country has increased the annual registration fee that needs to be paid by firms that produce medical devices. E.

Bargaining power of suppliers
Suppliers can exert power by threatening to raise prices or reduce the quality of purchased goods and services Suppliers have greater bargaining power when there are only a few or a single supplier of an input. Firms buying these inputs face high prices and their profitability is limited because there are little to no alternatives for this input. bargaining power of suppliers can change over time because of changes in technology and demand

Nutco is a cashew-processing firm that operates in the developing country of Ecotopia. After procuring raw cashews from farms around the country, Nutco processes them using a labor-intensive method. The workers at Nutco recently demanded a 20 percent increase in their overtime wage rate. All members of Nutco's labor union, which was a substantial proportion of the company's labor force, went on an unannounced strike when the management only agreed to a 5 percent hike. During negotiations that followed, the management informed the union leader that this was a take-it-or-leave-it offer. The union leader was not convinced and declared that the workers would not come back to work unless their demands were fully met. Kurt Whitman, Nutco's human resources manager, however thinks that the strike will end soon because of the company's strong stand. Which of the following, if true, would suggest that the labor union's threat of not resuming work is credible? A. Due to the occupational hazards of cashew-processing, the Ministry of Labor closely monitors the working conditions in this industry. B. The yield of cashews this year was low due to unfavorable climatic conditions. C. Most of Nutco's employees are migrant female workers who are willing to work for slightly lower wages. D. Most firms cannot take advantage of economies of scale because the industry is highly fragmented. E. The demand for labor in this industry has increased due to an increase in the demand for Ecotopian cashews abroad.

Until the late 1990s, airlines would post proposed changes in ticket prices on computer reservation systems several days before the new ticket prices went into effect. Then the federal government took action to end the practice. Now airlines can only post prices on their reservations systems for tickets that are immediately available for sale. Source: Scott McCartney, "Airfare Wars Show Why Deals Arrive and Depart," Wall Street Journal, March 19, 2002. Why would the federal government object to the old system of posting prices before they went into effect? A. The old system provided a way for firms to implicitly collude because one firm could propose a price change and the other firms could respond before the change went into effect. B. Proposing prices before they go into effect gives some airlines an unfair competitive advantage. C. The old system provided a way for firms to explicitly collude because one firm could propose a price change and the other firms could respond before the change went into effect. Your answer is correct. D. Posting prices that are not actually being offered is a form of false advertising.

The U.S. Department of Justice investigated whether the four major U.S. airlines were colluding. Some analysts believed the airlines were restraining increases in capacity by failing to buy more planes or fly additional routes in order to reduce pressure to cut ticket prices. An airline industry analyst commented on the investigation, "I don't sense that the executives talk to each other. They actually hate each other, truth be told. But with so few of them left, there's almost a natural oligopoly." Source: Christopher Drew, "Airlines Under Justice Dept. Investigation Over Possible Collusion," New York Times, Jul 1, 2015. a.

World War I began in August 1914 and on the Western Front quickly bogged down into trench warfare. In Belgium and northern France, British and French troops were dug into trenches facing German troops a few hundred yards away. The troops continued firing back and forth until a remarkable event occurred, which historians have labeled "The Christmas Truce." On Christmas Eve, along several sectors of the front, British and German troops stopped firing and eventually came out into the area between the trenches to sing Christmas carols and exchange small gifts. The truce lasted until Christmas night in most areas of the front, although it continued until New Year's Day in a few areas. Most of the troops' commanding officers were unhappy with the truce-they would have preferred the troops to keep fighting through Christmas-and in the future they often used a policy of rotating troops around the front so that the same British and German troops did not face each other for more than relatively brief periods. Source: Robert M. Sapolsky, "The Spirit of the 1914 Christmas Truce," Wall Street Journal, December 19, 2014.

in game theory, a game in which the parties make their moves in turn, with one party making the first move, followed by the other party making the next move, and so on
repeated game
in game theory, a game that is played again sometime after the previous game ends Many business situations are repeated games. Because they are repeated games, firms may end up implicitly colluding to keep prices high
The North Carolina State Board of Dental Examiners had been requiring that only licensed dentists be allowed to sell teeth-whitening services. The board brought legal action against hair salons and spas that also offered these services arguing that only licensed dentists had the training to ensure that consumers weren't injured in the teeth-whitening process. In 2015, the U.S. Supreme Court ruled that a federal government agency had the authority to stop the board from preventing non-dentists from offering teeth-whitening services. According to a news report, the federal agency argued that "the dental board was motivated by financial self-interest, not health concerns." Source: Brent Kendall, "Supreme Court Affirms FTC Antitrust Authority Over Licensing Boards," Wall Street Journal, February 25, 2015.

C. increase and the price to fall. Your answer is correct. D. decrease and the price to fall. The well-being of consumers of teeth-whitening services in North Carolina A. will decrease because the service they receive from non-dentists will be less thorough compared to what they receive from dentists. B. will increase because prices fall and consumer surplus rises. C. may increase as a result of larger consumer surplus, but may decrease if there is injury as a result of non-dentists offering the services. Your answer is correct. D. cannot be determined because we don't know their preferences.

For several years, a professor at Johns Hopkins University had been using the following grading scheme for his final exam: He would give an A to the student with the highest score. The grades of the remaining students were then based on what percentage their scores were of the top student's score. In the fall of 2012, the students in the class came up with the idea of boycotting the final exam. They stood in the hallway outside the classroom but did not enter the room to take the exam. After waiting for a time, the professor cancelled the exam and, applying his grading scale, gave everyone in the class an A on the exam. An article in the New York Times about this incident observes: "This is an amazing game theory outcome, and not one that economists would likely predict." Source: Catherine Rampell, "Gaming the System," New York Times, February 14, 2013.
