  • Collusive vs. Non-Collusive Oligopoly: A Comparison

Welcome to our latest blog post where we will dive into the fascinating world of oligopoly. Have you ever wondered how companies like Apple and Samsung dominate the smartphone industry? Or why do airlines seem to charge similar prices for flights despite being competitors? The answer lies in oligopoly.

Collusive Oligopoly is a market structure where a few firms cooperate and coordinate their actions to maximize joint profits through agreements and collusion. While Non-Collusive Oligopoly is a market structure where firms compete independently without formal agreements or collusion, employing competitive strategies to gain market share.

Collusive vs. Non-Collusive Oligopoly

Collusive OligopolyNon-Collusive Oligopoly
Collusive oligopoly is a market structure where a few firms coordinate their actions to maximize joint profits.Non-collusive oligopoly is a market structure where firms compete with each other independently without any formal agreement or collusion.
Firms in a collusive oligopoly engage in collusion, such as price-fixing, output restrictions, or market allocation, to avoid direct competition and maintain higher prices.Firms in a non-collusive oligopoly compete with each other through pricing strategies, product differentiation, advertising, and other competitive tactics to gain market share.
Collusive oligopolistic firms collectively possess significant market power, enabling them to control prices and restrict output in their favor.Non-collusive oligopolistic firms also hold market power individually, but their actions are not coordinated, leading to independent decision-making and potentially more competitive outcomes.
The firms are highly interdependent as their actions and decisions are influenced by agreements and understandings with other firms in the market.The, firms are still interdependent to some extent, as their actions and strategies are influenced by the behavior and performance of their competitors. However, there is no formal coordination or collaboration.
Collusive oligopoly faces the risk of cheating among the participating firms, where some firms may deviate from the agreed-upon collusive behavior to gain a competitive advantage.Non-collusive oligopoly faces the risk of intense price competition, aggressive advertising, and other competitive tactics employed by firms to gain a larger market share.
It tends to exhibit more stable market conduct, with less price volatility and reduced uncertainty for the participating firms.It is often experiences more dynamic market conduct, characterized by price fluctuations, product innovation, and a higher degree of competitive intensity.
Collusive oligopoly practices, such as price-fixing and market allocation, are generally considered illegal and subject to antitrust regulations and penalties.Non-collusive oligopoly, as long as firms compete fairly without engaging in anticompetitive behavior, operates within the legal framework of competition law and regulations.

Definition of Collusive and Non-Collusive Oligopoly

Collusive Oligopoly: Collusive oligopoly refers to a market structure where a small number of firms coordinate their actions and make agreements to limit competition, manipulate prices, or control market share, with the aim of maximizing their joint profits.

Non-Collusive Oligopoly: Non-collusive oligopoly is a market structure where firms compete with each other independently, without any formal agreements or coordination. Each firm in a non-collusive oligopoly makes decisions based on its own strategic considerations, such as pricing, advertising, and product differentiation, to gain a competitive edge in the market.

Similarities between Collusive and Non-Collusive Oligopoly

  1. Both collusive and non-collusive oligopolies involve a small number of firms operating in the market.
  2. In both collusive and non-collusive oligopolies, firms have significant market power and can influence market outcomes.
  3. Both types of oligopolies can result in barriers to entry, making it difficult for new firms to enter the market.
  4. Both collusive and non-collusive oligopolies require firms to engage in strategic decision-making to gain a competitive advantage.
  5. Both collusive and non-collusive oligopolies can lead to interdependence among firms, where their actions and strategies are influenced by the behavior of their competitors.

Examples of Collusive and Non-Collusive Oligopolies

Examples of Collusive Oligopoly:

  1. OPEC (Organization of the Petroleum Exporting Countries) in the global oil market, where member countries coordinate production levels and prices to control oil supply and stabilize prices.
  2. Cartels in the illegal drug trade, where different criminal organizations collaborate to control the production, distribution, and pricing of illicit drugs.

Examples of Non-Collusive Oligopoly:

  1. Automobile industry, where major car manufacturers compete independently by implementing various pricing strategies, product differentiation, and marketing campaigns.
  2. Mobile phone industry, with companies like Apple, Samsung, and Huawei competing with each other through innovation, marketing, and pricing to gain market share and attract customers.

Pros and cons of both

Pros of Collusive Oligopoly:

  1. Stability: Collusive oligopolies can provide stability in terms of prices and market conditions, as firms coordinate their actions to avoid intense price competition.
  2. Profit Maximization: Collusive agreements allow firms to maximize their joint profits by collectively setting prices and output levels.
  3. Reduced Uncertainty: Collusive oligopolies can reduce uncertainty for participating firms, as they have a better understanding of how their competitors will behave.

Cons of Collusive Oligopoly:

  1. Higher Prices: Collusion can result in higher prices for consumers, as firms manipulate prices to maximize their profits.
  2. Lack of Competition: Collusive oligopolies reduce competition in the market, limiting consumer choice and potentially stifling innovation.
  3. Risk of Breakdown: Collusive agreements can be unstable and prone to breaking down if firms cheat or deviate from the agreed-upon strategies.

Pros of Non-Collusive Oligopoly:

  1. Competitive Pricing: Non-collusive oligopolies promote price competition among firms, leading to potentially lower prices for consumers.
  2. Innovation: In a non-collusive oligopoly, firms compete to differentiate their products and innovate, which can lead to technological advancements and improved offerings for consumers.
  3. Consumer Choice: Non-collusive oligopolies provide consumers with a wider range of options and choices in terms of products and services.

Cons of Non-Collusive Oligopoly:

  1. Potential Price Instability: Non-collusive oligopolies can experience price volatility due to intense competition, which may lead to uncertain pricing patterns.
  2. Predatory Practices: Firms in non-collusive oligopolies may engage in predatory pricing or aggressive tactics to gain a competitive advantage, potentially harming smaller competitors.
  3. Limited Market Entry: Non-collusive oligopolies can create barriers to entry, making it challenging for new firms to enter the market and compete effectively.

Key differences between Collusive and Non-Collusive Oligopoly

1. In a collusive oligopoly, there is an agreement between firms to cooperate in order to keep prices high and production low. In a non-collusive oligopoly, there is no such agreement and firms compete against each other.

2. In a collusive oligopoly, firms may engage in price fixing or other anti-competitive practices. In a non-collusive oligopoly, such practices are not possible since firms are competing against each other.

3. Collusive oligopoly can be seen as a cartel while a non-collusive oligopoly cannot.

4. Collusive oligopoly is illegal under many antitrust laws while non-collusive oligopoly is not.

Differences between Collusive and Non-Collusive oligopoly


Collusive oligopoly involves firms engaging in secret agreements in order to increase their profits, whereas non-collusive oligopoly is characterized by a lack of cooperation among the firms and a focus on competition instead. Understanding these two types of market structures can help businesses better identify which type they are operating within and adjust their strategy accordingly.
