6.4 Applications to collusion and tacit cooperation
3 min read•august 7, 2024
in business can take many forms, from explicit agreements to subtle coordination. Firms may divide markets, set prices, or limit output to boost profits. These practices, while tempting, are often illegal and unstable.
Antitrust policies aim to stop collusion and promote competition. Authorities use tools like and to catch cartels. But detecting tacit collusion remains tricky, as firms find sneaky ways to cooperate without getting caught.

- Collusion involves firms in an industry coordinating their behavior to achieve higher profits than they would under competition
- consists of direct communication and formal agreements between firms to coordinate prices, quantities, or market shares
- or collusion occurs when firms coordinate their behavior without explicit communication or formal agreements
- Firms may engage in tacit collusion by observing and responding to each other's actions in the market
- Tacit collusion can lead to outcomes similar to explicit collusion without the need for direct communication
Market Sharing Arrangements
- involves firms dividing up the market and agreeing not to compete in each other's designated segments
- Firms may divide the market geographically, by customer type, or by product line
- Market sharing allows firms to act as monopolists within their designated segments, leading to higher prices and profits
- Examples of market sharing include:
- Oil companies agreeing to divide up global markets (Middle East, North America, Europe)
- Pharmaceutical companies agreeing not to compete in each other's therapeutic areas (cardiovascular drugs, oncology drugs)
Cartel Dynamics
Factors Affecting Cartel Stability
- refers to the ability of a collusive agreement to persist over time without firms deviating from the agreement
- Factors that influence cartel stability include:
- Number of firms in the industry (fewer firms make coordination easier)
- Similarity of firms' cost structures (more similar costs reduce incentives to deviate)
- (less elastic demand makes collusion more profitable)
- Frequency of interaction (more frequent interaction facilitates monitoring and punishment)
- Cartels are inherently unstable because firms have an incentive to cheat on the agreement by secretly lowering prices or increasing output
Price Wars and Punishment Strategies
- occur when firms in a collusive agreement deviate from the agreed-upon prices, leading to a breakdown of the cartel
- Firms may engage in price wars to punish cheaters or to gain market share
- Price wars can be costly for all firms involved, as they lead to lower profits
- are punishment mechanisms used to deter firms from cheating on a collusive agreement
- In a trigger strategy, firms agree to revert to competitive behavior (low prices, high output) for a period of time if cheating is detected
- The threat of a costly price war can deter firms from deviating from the collusive agreement
- Example: (Organization of the Petroleum Exporting Countries) has experienced price wars when member countries have exceeded their agreed-upon production quotas
Antitrust Enforcement
Antitrust Policy Objectives and Tools
- aims to promote competition and prevent collusive behavior that harms consumers
- Antitrust authorities use various tools to detect and prosecute collusion:
- Market monitoring and analysis to identify suspicious pricing patterns
- Leniency programs that offer reduced penalties to firms that report their involvement in a cartel
- Fines and criminal charges for firms and individuals found guilty of collusion
- Challenges in antitrust enforcement include detecting tacit collusion and balancing the benefits of cooperation (e.g., joint ventures, standard-setting) with the risks of anticompetitive behavior
Leniency Programs and Cartel Detection
- Leniency programs offer reduced penalties or immunity to firms that report their involvement in a cartel and cooperate with antitrust authorities
- Leniency programs can destabilize cartels by creating incentives for firms to betray their partners
- The threat of a cartel member reporting the agreement can deter firms from engaging in collusion
- Markers are used in leniency programs to establish a firm's place in the queue for leniency
- The first firm to report a cartel and cooperate with authorities typically receives the most lenient treatment
- Examples of successful leniency programs include the US Department of Justice's Corporate Leniency Policy and the European Commission's Leniency Notice
Key Terms to Review (26)
Antitrust policy: Antitrust policy refers to a set of laws and regulations designed to promote competition and prevent monopolistic practices in the marketplace. This policy aims to protect consumers by ensuring that no single entity can dominate a market, which could lead to higher prices, reduced innovation, and decreased consumer choices. By regulating corporate behavior, antitrust policies are essential in addressing issues like collusion and tacit cooperation among firms that could stifle competition.
Cartel detection: Cartel detection refers to the methods and techniques used to identify and investigate collusive behavior among firms that coordinate their actions to control market prices or limit competition. This process is essential for regulatory bodies to maintain fair competition in markets, ensuring that consumers benefit from lower prices and more choices. Effective cartel detection combines economic analysis, data collection, and legal frameworks to uncover secretive agreements that harm market dynamics.
Cartel stability: Cartel stability refers to the ability of a group of firms to maintain collusion over time in order to maximize collective profits, often by controlling prices or limiting production. Stability is essential for cartels because it allows members to reap the benefits of their coordinated actions without being undermined by competition or defection from within. Factors such as market conditions, the number of participants, and external regulatory pressures play a crucial role in determining the stability of a cartel.
Coalition formation: Coalition formation is the process by which individuals or groups come together to form alliances in order to achieve common goals or enhance their bargaining power. This concept is particularly relevant in scenarios where parties may benefit from working together rather than acting independently, often seen in competitive environments such as markets or political arenas. Understanding coalition formation helps illuminate how collusion and tacit cooperation can arise among competitors seeking to maximize their collective payoffs.
Collusion: Collusion is an agreement between two or more players to coordinate their strategies in order to achieve a favorable outcome, often at the expense of others. This practice usually aims to manipulate market conditions, control prices, or limit competition. Understanding collusion involves examining how players interact, the strategies they employ, and the payoffs that motivate their decisions. It also connects with concepts of rationality, where players seek to maximize their own benefits while possibly harming competitors.
Cooperative Game Theory: Cooperative game theory is a branch of game theory that studies how players can work together to achieve a better outcome for all participants, rather than acting solely in their self-interest. This approach emphasizes the importance of forming coalitions and agreements among players to maximize their collective payoffs. By analyzing the ways in which players can collaborate, cooperative game theory provides insights into situations where teamwork can lead to improved results, such as in collusion, voting scenarios, and negotiation processes.
Demand elasticity: Demand elasticity refers to the degree to which the quantity demanded of a good or service changes in response to a change in its price. When demand is elastic, consumers significantly reduce their purchase amounts as prices rise, while inelastic demand indicates that changes in price have little effect on the quantity demanded. Understanding demand elasticity is crucial in analyzing pricing strategies, consumer behavior, and market dynamics, especially within contexts involving collusion and tacit cooperation among firms.
Explicit collusion: Explicit collusion refers to an agreement between firms in an industry to coordinate their actions, such as setting prices or output levels, with the intention of maximizing collective profits. This type of collaboration often involves direct communication and negotiation among firms, creating a formal arrangement that allows them to act as a single entity rather than competing against each other. Such practices are typically illegal in many jurisdictions due to their potential to undermine competition and harm consumers.
Focal Points: Focal points are solutions that people tend to choose in strategic situations when there is ambiguity or uncertainty, often due to social conventions or cultural norms. These points help players coordinate their strategies, especially when they cannot communicate directly. The significance of focal points lies in their ability to guide players toward a mutual decision, making them crucial in analyzing situations like pure strategy Nash equilibria and scenarios involving collusion and tacit cooperation.
Jean Tirole: Jean Tirole is a renowned French economist recognized for his significant contributions to industrial organization and game theory, particularly in understanding market structures and the behavior of firms. His work often emphasizes the complexities of competition, collusion, and regulatory policies in various industries, making his insights relevant to analyzing economic behavior in both theoretical and practical contexts.
Leniency Programs: Leniency programs are initiatives established by competition authorities that encourage firms involved in anti-competitive behavior, such as collusion, to come forward and provide evidence against their co-conspirators in exchange for reduced penalties or immunity from fines. These programs play a critical role in promoting competition by breaking the secrecy of collusive agreements and incentivizing firms to cooperate with authorities, ultimately leading to the dismantling of anti-competitive practices.
Market monitoring: Market monitoring refers to the process of observing and analyzing market behaviors, pricing, and strategies of competitors to maintain an advantageous position within the market. This practice is crucial for firms engaged in collusion or tacit cooperation, as it allows them to assess whether their partners are adhering to agreed-upon strategies, prices, or production levels. By effectively monitoring the market, firms can detect deviations from cooperative behavior and adjust their strategies accordingly to sustain profitability and stability in their agreements.
Market sharing: Market sharing is an agreement between competing firms to divide the market into segments, where each firm agrees to serve a specific portion of customers or geographic areas. This practice is often seen in collusive arrangements, where firms coordinate to reduce competition and increase their market power by stabilizing prices and output. It can be done explicitly through formal contracts or implicitly through tacit cooperation.
Monopoly power: Monopoly power is the ability of a firm or entity to set prices above the competitive level and control the market supply of a particular good or service. This power arises when a single seller dominates the market, leading to reduced competition and the potential for higher profits. It can have significant implications for consumer welfare and market dynamics, especially in the context of collusion and tacit cooperation among firms.
Nash Equilibrium: Nash Equilibrium is a concept in game theory where no player can benefit by unilaterally changing their strategy if the strategies of the other players remain unchanged. This means that each player's strategy is optimal given the strategies of all other players, resulting in a stable outcome where players have no incentive to deviate from their chosen strategies.
Oligopoly: An oligopoly is a market structure characterized by a small number of firms that dominate the market, leading to limited competition and the potential for collusion. In this setting, each firm holds significant market power, influencing prices and outputs while being mindful of the actions of rival firms. This interdependence creates a unique dynamic where firms may engage in tacit cooperation or explicit collusion to maximize profits.
Oliver Williamson: Oliver Williamson is an influential economist known for his work on transaction cost economics, which examines the costs associated with economic exchanges and how these costs affect organizational structures. His ideas have been crucial in understanding collusion and tacit cooperation among firms, emphasizing how firms choose to organize themselves to minimize costs and maximize efficiency in competitive environments.
OPEC: OPEC, or the Organization of the Petroleum Exporting Countries, is an intergovernmental organization formed in 1960 to coordinate and unify the petroleum policies of its member countries. By working together, OPEC aims to secure fair and stable prices for petroleum producers, ensure a steady supply of oil to consumers, and provide a fair return on capital to those investing in the petroleum industry. This collective approach connects directly to applications of collusion and tacit cooperation in the global oil market, as OPEC often behaves like a cartel by regulating production levels to influence oil prices.
Price Leadership: Price leadership is a pricing strategy where one leading firm sets the price for a product or service, and other firms in the industry follow suit. This practice often arises in oligopolistic markets, where a few firms dominate and their prices can influence competitors' pricing decisions. By establishing a price point, the leader helps to stabilize the market and reduce competitive pressure, which can lead to tacit cooperation among firms.
Price wars: Price wars are competitive exchanges among rival companies to undercut each other's prices, typically to gain market share or drive competitors out of the market. This aggressive pricing strategy can lead to reduced profit margins and potentially harm the overall industry if prolonged, impacting the dynamics of collusion and tacit cooperation among firms.
Prisoner's dilemma: The prisoner's dilemma is a standard example of a game in which two players must choose between cooperation and betrayal, with the outcome for each dependent not only on their own choice but also on the choice made by the other player. This scenario highlights the conflict between individual rationality and collective benefit, demonstrating how two rational individuals may not cooperate even if it appears that it is in their best interest.
Punishment strategies: Punishment strategies are methods used to discourage undesirable behavior in strategic interactions by imposing costs or negative consequences on the offending party. These strategies play a vital role in maintaining cooperation among self-interested individuals, as they can deter deviations from agreed-upon actions, thus stabilizing relationships and fostering equilibrium outcomes. By aligning individual incentives with collective goals, punishment strategies contribute significantly to concepts like folk theorems and collusion dynamics.
Repeated games: Repeated games are strategic situations where the same game is played multiple times by the same players, allowing for the possibility of strategies to evolve based on past interactions. This framework enables players to build reputations, establish trust, and potentially achieve cooperative outcomes that would not be attainable in a one-shot game. The dynamics of repeated interactions can lead to various equilibria, including the possibility of sustaining cooperation over time.
Stochastic games: Stochastic games are a type of game theory framework that incorporates randomness and strategic interactions over time, allowing for dynamic decision-making in uncertain environments. These games involve multiple players making decisions at various stages, where the outcomes depend not only on the players' actions but also on probabilistic events. This setting is particularly relevant for understanding how collusion and tacit cooperation can emerge among players when faced with uncertain rewards and potential punishments.
Tacit cooperation: Tacit cooperation refers to the implicit understanding among individuals or firms to coordinate their actions without explicit agreements or communication. This concept often arises in contexts where parties have shared interests and recognize that working together can lead to mutual benefits, as seen in collusion among competitors who avoid undercutting each other's prices.
Trigger Strategies: Trigger strategies are contingent plans used in repeated games where a player responds to another player's actions with predetermined responses, often designed to enforce cooperation or deter defection. These strategies can be particularly effective in sustaining equilibrium outcomes by threatening punitive responses to uncooperative behavior. They are essential in understanding dynamics like collusion, as they help maintain cooperative agreements among players through the threat of reverting to a less favorable strategy if the agreement is violated.
