== Cartel vs. Oligopoly ==
An oligopoly is a market structure dominated by a small number of large sellers, while a cartel is a formal agreement among competing firms to control prices, production, and other market variables.<ref name="ref1" /><ref name="ref2" /><ref name="ref3" /> Although cartels often form within oligopolistic markets, the two terms are not interchangeable. An oligopoly can exist without a formal collusive agreement, whereas a cartel is defined by such an agreement.<ref name="ref1" /><ref name="ref4" />

In an oligopoly, firms are interdependent; the actions of one firm significantly impact the others, leading to strategic decision-making regarding pricing and output.<ref name="ref1" /><ref name="ref5" /> This can result in tacit collusion, where firms coordinate their actions without an explicit agreement, or non-collusive competition.<ref name="ref1" /> A key characteristic of oligopolies is the presence of high barriers to entry, such as substantial capital requirements, patents, or strong brand loyalty, which limit the number of new competitors.

A cartel, on the other hand, involves explicit collusion.<ref name="ref4" /> Members of a cartel enter into a formal agreement to act as a single entity to maximize collective profits.<ref name="ref2" /> These agreements typically involve price-fixing, setting production quotas, allocating markets, or rigging bids. Unlike the broader market structure of an oligopoly, cartels are illegal in most jurisdictions due to their anti-competitive nature.

=== Legality and Enforcement ===
Antitrust laws in many countries, such as the Sherman Antitrust Act in the United States, explicitly prohibit the formation and operation of cartels. These laws are designed to prevent practices that restrain trade and harm consumers through artificially high prices and reduced choice. Violators can face severe penalties, including substantial fines for companies and imprisonment for the individuals involved.

An oligopolistic market structure itself is not illegal. However, if the firms within an oligopoly engage in collusive practices that resemble a cartel, such as price-fixing, they can be prosecuted under antitrust laws.<ref name="ref1" /> Proving tacit collusion can be difficult for regulators, as it does not involve an overt agreement.<ref name="ref1" />

=== Stability and Market Impact ===
Cartels are often difficult to sustain because individual members have a strong incentive to cheat. By secretly lowering its price or increasing its output, a single member can capture a larger market share and increase its profits at the expense of other members.<ref name="ref3" /> This inherent instability can lead to the breakdown of the cartel agreement.

Oligopolies, while potentially competitive, can also lead to market outcomes that are detrimental to consumers, such as higher prices and less innovation, even without a formal cartel agreement. The interdependence of firms can create price rigidity, where firms are reluctant to change prices for fear of triggering a price war.<ref name="ref5" />
