Cartel Oligopoly
A cartel oligopoly is a market structure in which a small group of firms (typically 2-4) collude to coordinate their actions and maximize their collective profits. Cartel members agree to set prices, output levels, and market shares to avoid competition and maintain high prices.
Characteristics of Cartel Oligopoly:
- Small Number of Firms: A cartel is formed when a few large firms dominate the industry, controlling a significant portion of the market.
- Collusion: Firms explicitly agree to coordinate their behavior, including pricing, output, and market shares.
- Market Power: By acting as a unified entity, cartel members gain significant market power, allowing them to restrict competition and set prices above the competitive level.
- Barriers to Entry: High barriers to entry, such as economies of scale, patents, or government regulations, make it difficult for new firms to enter the market and challenge the cartel.
Formation of Cartels:
Cartels are typically formed when firms recognize that they can gain higher profits by cooperating rather than competing. Factors that can lead to cartel formation include:
- Economic Interdependence: Firms in the same industry are highly dependent on each other for sales and inputs.
- Similarity in Products: Firms produce similar products, making it easier to coordinate pricing and output.
- Common Interests: Firms share similar goals, such as maximizing profits or minimizing risk.
- Low Information Costs: Firms have access to information about each other's costs, production levels, and sales, which facilitates collusion.
Pricing and Output in Cartel Oligopoly:
Cartels typically use one of two pricing strategies:
- Cournot Model: Firms set output levels strategically, taking into account the expected output of other cartel members. The equilibrium price and output are determined by the interaction of these strategies.
- Bertrand Model: Firms compete on price, setting prices below the cartel target to gain market share. However, cartel members may retaliate by lowering prices further, leading to a "price war."
Cartel members also agree on market shares to prevent any one firm from dominating the market. This can be achieved through quotas, production caps, or agreements on specific customer segments.
Stability and Enforcement:
Cartels are inherently unstable due to incentives for firms to cheat and gain a competitive advantage. To maintain stability, cartels need mechanisms to enforce agreements and punish deviations. These mechanisms may include:
- Agreements on Penalties: Cartel members agree on penalties for cheating, such as fines or expulsion.
- Monitoring and Verification: Firms regularly exchange information to monitor compliance with cartel agreements.
- Third-Party Facilitators: Lawyers, accountants, or consultants may assist in coordinating cartel activities and enforcing agreements.
Antitrust Laws and Cartels:
Cartel agreements are illegal in most jurisdictions due to their anti-competitive nature. Antitrust laws prohibit firms from engaging in activities that restrain trade, including price fixing, output restrictions, and market sharing. Governments can impose penalties, fines, and criminal charges against companies and individuals involved in cartels.
Examples of Cartel Oligopolies:
- OPEC: The Organization of the Petroleum Exporting Countries (OPEC) is a cartel composed of 13 oil-producing countries that control a significant portion of the global oil market.
- De Beers: De Beers is a diamond cartel that controlled the world's diamond supply for over a century.
- Pharmaceutical Industry: Several cases of price fixing and market sharing have been uncovered in the pharmaceutical industry, with large companies forming cartels to maintain high drug prices.
Conclusion:
Cartel oligopolies represent a form of market failure where firms collude to reduce competition, maximize profits, and restrict consumer choice. While cartels can provide benefits to member firms, their anti-competitive practices can harm consumers and negatively impact economic efficiency. Antitrust laws are essential for preventing and breaking up cartels and promoting a competitive market environment.
