Which market structure is characterized by a few firms dominating the market and producing similar or identical goods, and is more competitive than a monopoly?

• A. Oligopoly
• B. Monopoly
• C. Monopolistic Competition
• D. Perfect Competition

Answer: (A)

The key idea is a market with only a few large firms that together dominate the industry and sell products that are very similar or the same. In this setup, each firm must think about how the others will respond to its decisions, leading to strategic behavior and interdependence. This makes the market more competitive than a monopoly because there is more than one major producer competing for customers, even though entry barriers keep it from being perfectly competitive. It’s not a monopoly, which has a single seller, nor monopolistic competition, which features many firms offering differentiated products, nor perfect competition, where many firms sell identical goods and none can influence the price. So the described market structure is oligopoly.
