Under what condition does a natural monopoly (natuurlijk monopolie) typically develop in an industry?

Answer and explanation

Correct answer: A. When economies of scale allow a single firm to supply the entire market at lower cost than multiple firms

  1. Step 1: A natural monopoly arises in industries with massive fixed infrastructure costs and declining average total costs (e.g., railway tracks, electricity grids, water mains). Step 2. Having multiple competing networks would duplicate enormous capital costs and be economically inefficient. Answer: When economies of scale allow a single firm to supply the entire market at lower cost than multiple firms. Why not the others: Legal monopolies arise from statutory decrees or patents; natural monopolies stem from cost structure.
