Which statement correctly identifies the market structure most consistent with many firms, differentiated products, and relatively easy entry?

• A. Monopolistic competition (many firms, differentiated products)
• B. Oligopoly (few large firms, interdependent pricing)
• C. Monopoly (single seller)
• D. Perfect competition (many firms, identical products)

Answer: (A)

Monopolistic competition describes a market with many firms, each selling a differentiated product. Because products are differentiated (brand, quality, features, service), each firm has some ability to set its own price rather than being a pure price taker. At the same time, entry and exit are relatively easy, so profits above normal tend to attract new competitors and push profits down in the long run. This combination—many firms, differentiated offerings, and easy entry—fits the scenario described. This differs from perfect competition, where products are identical and firms have no price-setting power; from monopoly, where a single seller with high barriers dominates the market; and from an oligopoly, where only a few large firms influence prices and entry is more restricted.
