Collusive Oligopoly

A collusive oligopoly occurs when firms in an oligopolistic market—where only a few companies dominate—agree to work together instead of competing against each other. They might set prices, limit aggregate supply, divide markets into segments, or engage in other practices that would typically be undercut by competition. Such collusion can be explicit, forming cartels like OPEC, or tacit, where firms indirectly coordinate actions without explicit agreement. The impact of a collusive oligopoly...

A non-collusive oligopoly is a market structure where only a few firms dominate but compete against each other. In this setting, firms are independently trying to outdo their rivals through competitive practices such as price cuts, marketing campaigns, and product innovations. They operate under mutual interdependence, where the actions of one firm can significantly impact the others, leading to a strategic game of competition. The impact of a non-collusive oligopoly can be varied. On the one...

An oligopoly is a market structure characterized by large firms that dominate the market, offering similar or identical products. This concentration of market power with few competitors creates a unique set of dynamics and strategic interactions. One of the defining features of an oligopoly is the interdependence among firms. Decisions made by one firm regarding prices, output, and advertising affect the market share and profits of all other firms in the industry. This mutual dependence often...

In the Cournot model, businesses compete based on the assumption that each firm chooses its production quantity by presuming its rivals’ output levels. No firm has an incentive to change its production quantity given the rivals’ output levels, resulting in a stable market price where all firms maximize their individual profits.Consider two companies that produce identical goods, such as two automobile manufacturers. Initially, Company A decides to produce 50 cars as a profit-maximizing output...

An oligopoly, where market power is concentrated among a few entities, can lead to unfair strategies that disrupt the competitive landscape and reduce economic efficiency. Unfair practices in an oligopoly can distort the market's natural competitive forces, leading to consumer harm. Such practices often include price-fixing, market division, collusion, predatory pricing, and product tying. Price-fixing involves firms agreeing to sell at a set price above the competitive equilibrium, effectively...
