Difficulty: HardMonopoly: Characteristics and Sources of Monopoly Power

Match each source of monopoly power on the left with its corresponding economic foundation or market scenario on the right.

  • Natural MonopolyA situation where long-run average costs decline continuously over the entire range of market demand, making single-firm production cheapest.
  • Statutory (Legal) MonopolyAn exclusive operating right granted by government decree, parliamentary act, or public utility charter.
  • Technological MonopolyOwnership of proprietary technical knowledge, specialized secrets, or patent protection prohibiting replication.
  • Collusive Monopoly (Cartel)A formal agreement among independent firms to restrict aggregate output and jointly dictate market price as a unified entity.

Answer

Natural Monopoly matches with continuous long-run average cost decline over market demand; Statutory Monopoly matches with exclusive government decrees or charters; Technological Monopoly matches with proprietary technical knowledge and patents; Collusive Monopoly matches with formal agreements among independent firms to jointly dictate prices.
Each classification accurately reflects the underlying economic origin of market power: Natural monopoly relies on structural economies of scale; Statutory monopoly relies on state legal grants; Technological monopoly relies on patents and secret processes; and Collusive monopoly relies on cartel agreements among independent firms.

Step-by-Step Solution

1
Analyze Natural Monopoly
Identified that natural monopolies stem from structural economies of scale where a single firm's long-run average cost (LRAC) declines throughout the market capacity.
Economic theory defines a natural monopoly by cost advantages arising naturally from scale rather than legal barriers.
2
Analyze Statutory Monopoly
Linked statutory monopoly to government laws, decrees, or public utility concessions.
Statutory barriers are explicitly created by legal authority.
3
Analyze Technological Monopoly
Connected technological monopoly to patents and exclusive technical know-how.
Control over technical processes prevents rivals from entering the industry due to technical entry barriers.
4
Analyze Collusive Monopoly
Matched collusive monopoly with cartels and output-coordination agreements among separate producers.
When oligopolists collude formally, they acquire collective monopoly power by behaving as a single firm.
