Which market structure is characterized by a small number of producers sharing the market?

• A. Monopoly
• B. Renewable Resource
• C. Oligopoly
• D. Natural rights

Answer: (C)

A small number of producers sharing the market is an oligopoly. In this setup, each firm has substantial influence, but because there are only a few players, each firm must consider how the others will respond when it sets prices or output. High barriers to entry—like large capital needs, brand loyalty, or access to technology—keep new firms from joining easily. Because of this interdependence, prices and production levels tend to be more stable than in a perfectly competitive market, and firms often compete through branding, product differences, or advertising rather than by undercutting each other on price. Classic examples include airlines or automobile manufacturers, where a handful of big players dominate. This is different from a monopoly, which has a single producer, and from concepts like renewable resource or natural rights, which are not market structures.
