In this article, we are going to define oligopoly.
What are they and how do they work? How do I know if I am facing one?
Let’s dive in.
An oligopoly is a market structure in which a small number of firms dominate the industry. Oligopolies often arise in industries where there are high barriers to entry, such as in industries with high fixed costs or where there are significant economies of scale.
In an oligopoly, each firm is aware of the actions and reactions of its competitors, and decisions made by one firm can significantly impact the other firms in the market.
As a result, firms in an oligopoly market may engage in strategic behaviour, such as setting prices or engaging in non-price competition, in order to gain an advantage over their competitors.
Oligopolies can take various forms, such as a pure oligopoly, in which there are only a few firms producing a homogenous product; a differentiated oligopoly, in which firms produce slightly different products; or a Cournot oligopoly, in which firms compete by choosing how much to produce.
One of the key characteristics of oligopoly is the interdependence of firms.
In an oligopoly, each firm is aware of the actions and reactions of its competitors, and the decisions made by one firm can significantly impact the other firms in the market.
This interdependence can lead to strategic behaviour among oligopolists, as they try to anticipate the actions of their competitors and respond accordingly.
Another characteristic of oligopoly is the existence of barriers to entry.
These barriers can be economic, such as high fixed costs or economies of scale, or non-economic, such as regulatory barriers or brand recognition.
The high barriers to entry in an oligopoly market allow the existing firms to maintain their dominant positions and prevent new firms from easily entering the market.
Oligopoly markets can take various forms, including pure oligopoly, differentiated oligopoly, and Cournot oligopoly. In a pure oligopoly, there are only a few firms producing a homogenous product.
An example of a pure oligopoly is the market for gasoline, in which a small number of firms control the majority of gas stations and produce a product that is largely the same across all brands.
In a differentiated oligopoly, firms produce slightly different products, but the products are still close substitutes.
An example of a differentiated oligopoly is the market for airlines, in which a small number of firms offer slightly different services and routes, but the overall product (transportation by plane) is largely the same.
In a Cournot oligopoly, firms compete by choosing how much to produce.
Each firm takes into account the expected production of its competitors when deciding how much to produce.
This form of oligopoly is named after French economist Antoine Augustin Cournot, who first formalized the concept in the 19th century.
An oligopoly can have both positive and negative effects on consumers and the economy.
On the one hand, oligopoly may lead to increased efficiency and innovation, as firms strive to differentiate themselves and offer the best products or services to attract customers.
Oligopoly may also lead to lower prices for consumers, as firms compete on price to win market share.
On the other hand, oligopoly can also lead to reduced competition and higher prices for consumers. In some cases, oligopolists may collude to limit production and raise prices, leading to reduced consumer welfare.
Oligopoly may also discourage new firms from entering the market, which can stifle competition and innovation.
To address these potential negative consequences of oligopoly, governments may implement various regulatory measures.
For example, anti-trust laws can be used to prevent firms from colluding and engaging in anticompetitive behaviour. Merger regulations can also be used to prevent the concentration of market power in the hands of a few firms.
An oligopoly is a market structure characterized by a small number of firms dominating an industry and the interdependence of those firms.
Oligopoly can have both positive and negative effects on consumers and the economy, and governments may implement various regulatory measures to address potential negative consequences.
There are several different types of oligopoly, each with its own characteristics and dynamics.
Pure oligopoly: In a pure oligopoly, there are only a few firms producing a homogenous product. These firms have a high level of market power and are able to influence the price of their product. Because the products are identical, firms in a pure oligopoly may engage in price competition, trying to undercut each other to win market share.
Differentiated oligopoly: In a differentiated oligopoly, firms produce slightly different products, but the products are still close substitutes. Firms in a differentiated oligopoly may engage in non-price competition, such as advertising or product innovation, to differentiate themselves from their competitors and attract customers.
Cournot oligopoly: In a Cournot oligopoly, firms compete by choosing how much to produce. Each firm takes into account the expected production of its competitors when deciding how much to produce. This form of oligopoly is named after French economist Antoine Augustin Cournot, who first formalized the concept in the 19th century.
Bertrand oligopoly: In a Bertrand oligopoly, firms compete on price. Each firm takes into account the expected price of its competitors when deciding how much to charge for its product. This form of oligopoly is named after French economist Joseph Louis François Bertrand, who first developed the concept in the late 19th century.
It’s important to note that these types of oligopolies are not mutually exclusive and can sometimes overlap in real-world markets. For example, a market may be a pure oligopoly in terms of the number of firms, but the firms may still engage in non-price competition to differentiate themselves from each other.
Understanding the type of oligopoly a market is can help inform the strategies that firms may use to compete and the potential outcomes for consumers and the economy.
Oligopoly can be found in various industries, including the following:
The automobile industry is often cited as an example of an oligopoly. A small number of firms, such as Toyota, General Motors, and Volkswagen, dominate the market and have a significant level of market power.
These firms engage in various forms of competition, including price competition and non-price competition, such as advertising and product innovation.
The telecommunications industry is also often cited as an example of an oligopoly.
A small number of firms, such as AT&T, Verizon, and T-Mobile, dominate the market for mobile phone service and have a significant level of market power.
These firms engage in various forms of competition, including price competition and non-price competition, such as advertising and offering various plans and packages to attract customers.
The aerospace industry is another example of an oligopoly. A small number of firms, such as Boeing and Airbus, dominate the market for commercial aeroplanes and have a significant level of market power.
These firms engage in various forms of competition, including non-price competition, such as advertising and product innovation, as well as bidding on contracts with airlines.
It’s worth noting that oligopoly markets can change over time as new firms enter the market or existing firms exit.
For example, the automobile industry was once dominated by a few American firms, but it has become more globalized in recent decades with the rise of Asian firms such as Toyota and Hyundai.
In an oligopoly, firms may use various pricing strategies to compete with each other and gain an advantage in the market. Some common pricing strategies in oligopoly include the following:
Price leadership: In price leadership, one firm takes the lead in setting the price for the industry. The other firms in the market then follow the price set by the leader. This can occur through explicit collusion, where the firms agree to follow the price set by the leader, or through implicit collusion, where the firms follow the price set by the leader without explicitly agreeing to do so. Price leadership can lead to stable prices in the market, but it can also lead to reduced competition and higher prices for consumers if the firms collude to limit production and raise prices.
Price matching: In price matching, firms match the price of their competitors in order to remain competitive. This can occur through explicit agreements between firms or through implicit behavior, where firms adjust their prices in response to the prices set by their competitors. Price matching can lead to increased competition and lower prices for consumers, but it can also lead to a price war, where firms continually lower their prices to win market share, potentially leading to reduced profits for the firms.
Price discrimination: In price discrimination, firms charge different prices for the same product to different groups of customers. This can occur through various methods, such as offering discounts to certain groups or charging higher prices in certain locations. Price discrimination can lead to increased profits for the firms, but it can also lead to reduced consumer welfare if certain groups are charged higher prices than they are willing to pay.
It’s important to note that these pricing strategies are not mutually exclusive and firms may use multiple strategies in combination to compete in an oligopoly market. Understanding the pricing strategies used by firms in an oligopoly can help inform the potential outcomes for consumers and the economy.
In addition to pricing strategies, firms in an oligopoly may also engage in non-price competition in order to gain an advantage in the market. Some common forms of non-price competition in oligopoly include the following:
Advertising: Firms may engage in advertising to differentiate themselves from their competitors and attract customers. Advertising can take various forms, such as television commercials, print ads, or online ads. Firms may also use other forms of promotion, such as sponsorships or partnerships, to increase brand awareness and attract customers.
Innovation: Firms may also compete by introducing new and innovative products or services to the market. This can be a way for firms to differentiate themselves from their competitors and attract customers. Innovation can also lead to increased efficiency and reduced costs for the firm, which can be passed on to consumers in the form of lower prices.
Quality of products and services: Firms may also compete on the quality of their products and services. This can include offering higher quality products, better customer service, or more convenient delivery options. Firms that focus on the quality of their products and services may be able to differentiate themselves from their competitors and attract more customers.
It’s important to note that non-price competition can take many forms and may vary depending on the industry and the specific market conditions. Understanding the types of non-price competition used by firms in an oligopoly can help inform the potential outcomes for consumers and the economy.
To address potential negative consequences of oligopoly, such as reduced competition and higher prices for consumers, governments may implement various regulatory measures.
Some common regulatory measures used to address oligopoly include the following:
Anti-trust laws: Anti-trust laws, also known as competition laws, are designed to prevent firms from engaging in anticompetitive behaviour, such as colluding to limit production and raise prices.
These laws can be used to enforce penalties on firms that engage in such behaviour and to prevent such behaviour from occurring in the future.
Merger regulations: Merger regulations are designed to prevent the concentration of market power in the hands of a few firms.
These regulations can be used to prevent mergers and acquisitions that would result in an oligopoly market structure or to require firms to divest certain assets in order to maintain competition in the market.
It’s worth noting that regulatory measures can vary by country and may be implemented at the national, regional, or local level. Understanding the regulatory measures in place in a given market can help inform the potential outcomes for consumers and the economy.
An oligopoly can have both positive and negative effects on consumers and the economy.

Oligopoly may also discourage new firms from entering the market, which can stifle competition and innovation.
To address these potential negative consequences of oligopoly, governments may implement various regulatory measures, such as anti-trust laws and merger regulations.
These regulatory measures can help promote competition and protect consumer welfare, but they may also have unintended consequences, such as reducing the incentives for firms to innovate or invest in new technologies.

It’s important to consider the potential trade-offs of oligopoly and the regulatory measures used to address it in order to understand the potential outcomes for consumers and the economy.
