Chapter 10

The term "tit-for-tat strategy" describes a policy in which a firm is prepared to match whatever change in strategy a competitor makes. This strategy involves responding to the actions of the competitor in the same manner, mirroring their moves. It is a cooperative strategy that aims to maintain a balanced and competitive relationship with the competitor. This approach is based on the principle of reciprocity and can be an effective way to navigate the competitive landscape.

A focal point is a cooperation-inducing strategy that is so compelling that a firm would expect all other firms to adopt it. It is a strategy that stands out as the most obvious or natural choice for all parties involved, making it highly likely that they will coordinate and cooperate based on this common understanding. In other words, a focal point strategy creates a clear and easily identifiable point of reference that all firms can agree upon, leading to cooperation and coordination among them.

Predatory pricing would not help facilitate coordination of pricing across firms in an industry. Predatory pricing refers to the practice of setting prices below cost in order to drive competitors out of the market. This strategy is aimed at gaining a dominant market position rather than coordinating pricing with other firms. In fact, predatory pricing can lead to intense price competition and disrupt any attempts at coordination among firms in the industry.

Price umbrella describes the situation created by a large dominant firm where smaller firms can find buyers as long as they sustain a lower price. This means that the dominant firm sets a high price, creating a "umbrella" or range within which smaller firms can compete by offering lower prices. The dominant firm's high price provides a benchmark for the market, and smaller firms can attract buyers by offering products or services at a lower price.

A firm might not be able to react quickly to competitors' pricing moves due to several reasons. Firstly, there may be lags in detecting competitors' prices, which means that the firm may not be aware of the changes in pricing immediately. Secondly, if the firm has infrequent interactions with competitors, it may not have access to timely information about their pricing strategies. Additionally, ambiguities in identifying which firm among a group of firms in a market is cutting price can cause confusion and delay the firm's response. Lastly, difficulties in distinguishing drops in volume due to price cutting by rivals from drops in volume due to anticipated decreases in market demand can further hinder the firm's ability to react quickly.

In the office supply industry, competitive pricing interactions are not affected by lumpy orders. This means that even if there are fluctuations or irregularities in the order sizes, it does not impact the pricing strategies and competition among suppliers in this industry. Unlike other industries such as airframe manufacturing, shipbuilding, supercomputing, and automobile seat manufacturing, where the size and timing of orders can significantly influence pricing dynamics, the office supply industry seems to have a more stable and consistent pricing environment regardless of order patterns.

In the airline travel industry, more "public" sales transactions enhance the likelihood of sustained cooperative pricing. This is because in the airline industry, prices are often publicly displayed and easily accessible to customers. When customers can easily compare prices and make informed decisions, it creates a competitive environment where airlines are more likely to cooperate and maintain fair pricing to attract and retain customers. Additionally, public sales transactions increase transparency, making it more difficult for airlines to engage in price-fixing or other anti-competitive practices.

According to Dixit and Nalebuff, when misreads are possible, strategies that are less provocable and more forgiving than tit-for-tat are more desirable to use. This means that it is better to avoid aggressive and retaliatory strategies and instead opt for strategies that are more cooperative and forgiving in order to maintain better relationships and outcomes in situations where misinterpretations can occur.

Price-sensitive buyers tend to harm cooperative pricing in a market because they are more likely to be tempted to cut prices, even if they expect competitors to match. This behavior can lead to a price war and undermine the cooperative pricing agreements that may have been in place. As a result, competitors may engage in aggressive price-cutting strategies, leading to lower profits for all parties involved and potentially damaging the overall market dynamics.

The Folk Theorem is the correct answer because it explains the situation where any price between the monopoly price and marginal cost can be sustained as an equilibrium in the infinitely repeated prisoner's dilemma game. This theorem states that in repeated games, players can achieve outcomes that are not possible in a one-shot game through the use of strategies that involve punishment and cooperation. In the context of the question, it means that players can sustain prices within a certain range due to the repeated nature of the game and the possibility of punishment for deviating from the agreed-upon price.

The significant threat of entry does not contribute to the low profitability of the heavy-duty truck engine industry. This means that there is not a high likelihood of new competitors entering the market, which can lead to increased competition and lower profitability.

A grim trigger strategy in a two firm repeated game is a strategy where a firm initially cooperates with its opponent, but as soon as the opponent aggresses, the firm switches to always aggressing for the remainder of the game. This strategy is called "grim trigger" because once the trigger of aggression is pulled by the opponent, the firm responds with continuous aggression, showing no forgiveness or willingness to cooperate again. This strategy is meant to deter the opponent from aggressing in the first place, as they know that any act of aggression will result in a permanent shift to aggression from the firm.

Barometric price leadership occurs when a dominant firm in the market sets the price, and other firms in the industry follow suit. In the case of a prime-rate loan, banks or financial institutions typically set the prime rate, which serves as a benchmark for other interest rates in the market. Other lenders then adjust their rates based on the prime rate, making it an example of barometric price leadership.

When the merge threatens to substantially increase market concentration, the Department of Justice and Federal Trade Commission are most likely to challenge the merge between two competitors. This is because increased market concentration can lead to reduced competition, which can negatively impact consumers by potentially resulting in higher prices, limited choices, and decreased innovation. The authorities aim to maintain a competitive market environment to protect consumer welfare and prevent the formation of monopolies or anti-competitive behavior.

Cooperative pricing refers to situations in which firms can sustain prices in excess of those that would arise in a non-cooperative single-shot price or quantity-setting game. In cooperative pricing, firms collaborate and work together to set prices at a higher level than what would be achieved individually. This allows them to maximize their profits and maintain higher prices in the market. Unlike non-cooperative pricing, where firms compete against each other, cooperative pricing involves cooperation and coordination among firms to achieve higher prices and avoid price wars.

Price following is a practice that can help firms facilitate cooperative pricing. This practice involves setting prices based on the prices set by a dominant firm in the market. By following the pricing decisions of the dominant firm, other firms can avoid price wars and maintain stability in the market. This can lead to cooperation among firms and prevent aggressive price competition.
