Which market structure describes many buyers and sellers trading in a uniform commodity like wheat or corn?

• A. Pure competition
• B. Monopolistic competition
• C. Oligopoly
• D. Monopoly

Answer: (A)

In a market with many buyers and sellers trading a uniform commodity like wheat or corn, the structure is pure competition. The distinguishing feature here is that the product is homogeneous—all the units are essentially the same—so no single seller can set the price. With many participants on both the buy and sell sides, everyone is a price taker, meaning they must accept the going market price rather than trying to charge a premium. Free entry and exit and full information about prices and quality also support this setup, keeping competition intense and preventing any one seller from gaining lasting market power. This fits best because the other structures involve elements that don’t align with a uniform commodity. Monopolistic competition has many sellers but product differentiation—think brands or variations—so each seller tries to distinguish their product and influence price a bit. An oligopoly features only a few sellers who may influence prices through interdependence. A monopoly has a single seller who sets prices without competition. None of these conditions describe a broad market for a standardized agricultural commodity the way pure competition does.
