Competition vs. Collusion: Strategic Choices in Oligopolistic Markets

Curated by Kelvin Hong, founder of The Economics Tutor. Part of our Free Economics Notes series.

Firms operating within various market structures, particularly oligopolies, face a fundamental strategic dilemma: whether to engage in aggressive competition for market share or to cooperate (collude) with rivals to collectively control market outcomes. This chapter delves into the economic implications of both competition and collusion, examining how the latter can lead to monopoly-like power and whether competition among oligopolies ultimately benefits or harms consumers. Through real-world examples, we will analyse the profound effects of these strategies on market efficiency, business profitability, and consumer welfare.

1. Competition vs. Collusion: Defining the Spectrum

Firms’ strategic interactions are shaped by the market structure they operate. While intense rivalry characterises some industries, others may exhibit degrees of explicit or implicit cooperation.

• Competition: Occurs when firms act independently and rivalrously to attract customers. This typically involves strategies such as:
  • Price Competition: Lowering prices to gain a larger share of the market.
  • Non-Price Competition: Differentiating products, improving quality, investing heavily in marketing and branding, enhancing customer service, or innovating to offer unique features.
• Collusion: Refers to an agreement (formal or informal) among competing firms to limit competition in a market. The aim is to jointly restrict output, fix prices, or divide markets, thereby increasing collective profits and acting more like a monopolist.

Understanding the dynamics and consequences of these opposing strategies is crucial for analysing business behaviour, market efficiency, and the role of regulatory bodies.

2. Monopoly Power When Firms Collude

2.1 What is Collusion?

Collusion effectively transforms an oligopolistic market into one that mimics a monopoly, allowing the colluding firms to collectively maximise profits at the expense of consumers. There are two primary forms:

• Explicit Collusion (Cartel): This involves a formal, overt agreement among competing firms to coordinate their actions. Common forms include:
  • Price-Fixing: Agreement to set prices at a predetermined level.
  • Output Restriction: Agreement to limit total industry output to drive up prices.
  • Market Sharing: Dividing geographical markets or customer segments among colluding firms. Explicit collusion is illegal in most countries, as it directly undermines the principles of free competition and harms consumer welfare.
• Tacit Collusion: This occurs when firms coordinate their actions without any formal agreement. Instead, they observe and anticipate each other’s moves, implicitly understanding that mutual restraint will lead to higher profits for all. This can manifest as:
  • Price Leadership: One dominant firm sets the price, and other firms follow.
  • Parallel Pricing: Firms independently change prices in the same direction and by similar amounts.
  • Avoidance of Price Competition: Firms may focus solely on non-price competition (e.g., advertising, product differentiation) to avoid disruptive price wars. While more difficult to prove, tacit collusion can still be investigated by competition authorities if it leads to anti-competitive outcomes.

2.2 Why Do Firms Collude?

Firms are incentivised to collude due to the potential for greater profitability and reduced market uncertainty:

• Higher Joint Profits: By restricting output and raising prices, colluding firms can move closer to the monopoly outcome, thereby increasing their collective producer surplus.
• Avoidance of Destructive Price Wars: In an oligopoly, aggressive price competition can erode profit margins for all firms, potentially leading to losses. Collusion offers a way to avoid such outcomes.
• Market Stability and Reduced Uncertainty: Collusion provides a predictable environment, reducing the uncertainty associated with rivals’ competitive actions and making long-term planning easier.
• Barriers to Entry: Successful collusion can create higher barriers to entry for potential new firms, as the established firms maintain high prices and profits without the typical competitive pressures.

2.3 Real-World Examples of Collusion

History is replete with examples of detected collusion, highlighting its prevalence despite illegality:

• OPEC (Oil Cartel): The Organisation of the Petroleum Exporting Countries is a classic example of an international cartel. Member countries coordinate oil production levels to influence global crude oil prices, directly impacting fuel prices worldwide. As a sovereign entity, OPEC operates outside national competition laws.
• Airline Cargo Price Fixing: In the early 2000s, major airlines, including British Airways, Virgin Atlantic, Lufthansa, and others, were found to have secretly colluded to fix fuel surcharges on air cargo shipments. This resulted in significant fines imposed by competition authorities globally.
• European Truck Cartel: From 1997 to 2011, major European truck manufacturers (e.g., Daimler, Volvo/Renault, DAF, MAN, Iveco) engaged in a long-running cartel to coordinate gross list prices for trucks and delay the introduction of new emissions technologies. The European Commission imposed a record €3.8 billion fine on the participating companies.

2.4 Impact of Collusion on Consumers

Collusion unequivocally harms consumers and reduces overall economic welfare:

• Higher Prices: Consumers are forced to pay artificially inflated prices, transferring significant consumer surplus to the colluding firms.
• Reduced Innovation: With less competitive pressure, firms have reduced incentives to invest in research and development, leading to slower product improvements and fewer new offerings.
• Lower Quality: Similarly, without competitive rivalry, firms may have less incentive to maintain or improve product quality.
• Restricted Choice: Collusion can limit the variety of products or services available as firms agree on specific offerings or market divisions.
• Allocative Inefficiency: Artificially high prices and restricted output mean that resources are not allocated efficiently according to consumer preferences, leading to a deadweight loss to society.

3. Does Competition Among Oligopolies Benefit Consumers?

An oligopoly is a market structure characterised by a small number of large firms that dominate the industry. A key feature of oligopolies is interdependence, meaning that each firm’s decisions significantly impact its rivals’ profits and strategies, and vice versa. This interdependence leads to complex strategic interactions, making the outcome of competition highly variable.

Examples of oligopolies include:

• Telecommunications: In Singapore, Singtel, StarHub, and M1 (and emerging players like SIMBA) dominate the mobile and broadband markets.
• Technology: Giants like Apple, Microsoft, Google, and Amazon operate in various oligopolistic segments (e.g., smartphones, operating systems, search engines, cloud computing).
• Automobiles: The global industry is dominated by a few large manufacturers like Toyota, Volkswagen, Hyundai-Kia, General Motors, Stellantis, and Tesla.

3.1 When Competition is Good for Consumers

When oligopolies engage in vigorous competition, it generally leads to significant benefits for consumers:

• Lower Prices: Firms compete by reducing prices to attract customers, leading to greater affordability.
  • Example: The intense competition among Singapore’s telecom providers, particularly with the entry of new virtual operators (MVNOs) and SIMBA (formerly TPG), has led to significant price wars for mobile data plans, resulting in cheaper options and larger data bundles for consumers.
• Better Quality and Innovation: To differentiate themselves, firms invest heavily in research and development (R&D) to improve product quality, introduce new features, and enhance performance.
  • Example: The fierce rivalry between Apple and Samsung in the smartphone market constantly drives advancements in camera technology, screen quality, processing power, and overall user experience, benefiting consumers with cutting-edge devices.
• More Choices and Variety: Competition encourages firms to offer a wider range of products, services, and price points to cater to diverse consumer preferences.
  • Example: In the ride-hailing market in Southeast Asia, the competition between Grab, Gojek, and traditional taxi operators (like ComfortDelGro in Singapore) has resulted in a variety of service options, pricing structures, and additional features (e.g., food delivery, payments) for consumers.
• Increased Efficiency: To offer lower prices or higher quality, firms are incentivised to improve their production processes, reduce waste, and achieve internal efficiencies.

3.2 When Competition Can Potentially Harm Consumers (or Lead to Market Failure)

While competition is generally beneficial, certain aggressive competitive behaviours in oligopolies can have negative long-term consequences:

• Price Wars Can Lead to Market Exit and Reduced Long-Term Competition: While initially beneficial, prolonged and severe price wars can drive some firms out of business, reducing the number of competitors. In the long run, this can lead to a more concentrated market with less competition, allowing remaining firms to raise prices later.
  • Example: Uber’s exit from the Southeast Asian market in 2018 (by selling its operations to Grab) was partly attributed to unsustainable losses from an intense price war with Grab. While Grab became dominant, the reduction in primary competitors allowed it to subsequently raise prices and reduce incentives, leading to regulatory concerns.
• Predatory Pricing: A particularly harmful form of aggressive price competition where a large, financially powerful firm temporarily slashes prices below cost to eliminate smaller rivals. Once competitors are driven out, the dominant firm can then raise prices to monopoly levels. This is illegal in most jurisdictions.
  • Example: While difficult to definitively prove, Amazon has faced accusations globally of using its vast financial resources and scale to offer products at extremely low prices, sometimes at a loss, to drive smaller retail competitors out of business, thereby increasing its market dominance.
• Excessive Marketing Costs: In an attempt to differentiate products where objective quality differences are minimal, oligopolistic firms may engage in intense and costly advertising or branding campaigns. These costs are often passed on to consumers through higher prices, without necessarily providing proportional increases in utility or quality.
  • Example: The ongoing “cola wars” between Coca-Cola and Pepsi involve massive advertising budgets aimed at fostering brand loyalty rather than significant product innovation. These marketing expenditures contribute to the final price consumers pay.

3.3 Case Study: Budget Airlines in Europe

The evolution of the European airline industry offers a compelling illustration of the mixed effects of competition:

• Positive Impact of Competition: The emergence and rapid growth of budget airlines (e.g., Ryanair, EasyJet, Wizz Air) from the late 1990s introduced intense price competition. This forced traditional full-service carriers (e.g., Lufthansa, Air France-KLM, British Airways) to significantly lower their ticket prices, unbundle services, and become more efficient. This phenomenon made air travel much more affordable and accessible to a broader segment of the population, leading to a substantial increase in overall air travel.
• Negative Consequences (Market Consolidation): In response to the intense competition and financial pressures, there has been significant consolidation among European airlines. Larger legacy carriers have acquired smaller or struggling regional airlines (e.g., Lufthansa acquiring parts of Air Berlin, Swiss, and nd Austrian Airlines; IAG acquiring British Airways and Iberia). While some consolidation might bring efficiencies, it has also reduced competition on specific routes, leading to fewer choices and potentially higher fares for consumers in those consolidated markets, thus diminishing some of the initial benefits of competition.

3.4 Why is Collusion Illegal?

Collusion is almost universally prohibited by competition law (also known as antitrust law) due to its profound negative impact on market efficiency and consumer welfare. Key reasons for its illegality include:

• Higher Prices for Consumers: The most direct and harmful effect, that colluding firms collectively exploit their market power.
• Reduced Competition: Collusion eliminates beneficial price wars, removes incentives for product differentiation, and stifles innovation, leading to a stagnant market.
• Lower Consumer Choice: Firms may agree to limit product variety or geographical reach, reducing options for consumers.
• Market Inefficiency (Allocative and Productive): Instead of competing to lower costs (productive efficiency) or matching supply with consumer demand at marginal cost (allocative efficiency), firms rely on mutual agreements to maintain high profits, leading to a misallocation of resources and a deadweight loss to society.
• Real-World Example: The Airline Price-Fixing Scandal (2000s): The extensive global investigations and massive fines imposed on major airlines for coordinating fuel surcharges on cargo and passenger flights served as a stark reminder of the widespread harm collusion causes. Passengers and businesses paid millions more than they should have, directly impacting their welfare and the economy.

3.5 Are There Any Legal Forms of Collaboration (often mistaken for collusion)?

While outright collusion is illegal, certain forms of inter-firm collaboration are permissible and even encouraged if they promote efficiency or innovation without harming competition:

• Joint Ventures: When two or more companies collaborate on specific projects (e.g., R&D partnerships, new product development, exploring new markets) while remaining independent entities for their core businesses. These are generally legal if their scope is limited and they do not lead to anti-competitive market-wide behaviour.
  • Example: Toyota and Subaru’s joint venture to develop the GR86/BRZ sports car allowed both companies to share R&D costs and leverage each other’s engineering expertise for a niche product.
• Government-Approved Cartels/Cooperation: In rare instances, usually at an international level or within specific regulated industries, governments may sanction cooperative agreements. These are exceptions typically justified by unique circumstances (e.g., managing natural resources, strategic industries) and are subject to strict oversight.
  • Example: While controversial, OPEC operates as a legal cartel under international law, as it consists of sovereign states coordinating oil production.

4. Conclusion

Firms operating in oligopolistic markets constantly weigh the benefits of fierce competition against the potential gains from collusion. While collusion can lead to monopoly-like power, higher profits for firms, and market stability, it profoundly harms consumers through inflated prices, reduced innovation, and overall market inefficiency. Consequently, it is largely illegal and heavily penalised by competition authorities.

Conversely, competition among oligopolies, when vigorous and fair, generally benefits consumers through lower prices, higher quality, greater product variety, and increased efficiency. However, overly aggressive competition, such as predatory pricing or ruinous price wars, can sometimes lead to market consolidation and reduced long-term competition if firms are driven out of business. Governments, therefore, play a crucial role in regulating markets to prevent anti-competitive collusion while fostering healthy competition that ultimately serves consumer welfare.

Discussion Questions

1. Why do firms, despite the severe legal consequences, still find collusion an attractive strategy? Discuss the economic incentives and challenges associated with maintaining a collusive agreement.
2. Can you think of a specific industry (other than those mentioned) where price competition has demonstrably helped consumers? Conversely, identify an industry where aggressive competition, perhaps even leading to predatory pricing, might have harmed consumers in the long run.

Given the potential benefits of competition and the harms of collusion, should governments intervene more aggressively in industries where oligopolistic structures make collusion more likely (e.g., highly concentrated markets, industries with high barriers to entry)? Justify your argument with economic reasoning.
