Explain the advantages and disadvantages of monopoly.

Answer Details

A monopoly is a market in which a single firm is the sole seller of a product that has no close substitutes, protected by barriers to entry.

Advantages of monopoly:

• Economies of scale: being large, the firm can produce at lower average cost and may pass part of the saving to consumers.
• Funds for research and development: supernormal profits can finance innovation and improved products.
• Avoids wasteful duplication: in the case of natural monopolies such as water or electricity supply, a single network is more efficient than several.
• Stability and continuity: the firm can plan long-term investment without the uncertainty of intense competition.
• Can practise price discrimination that may allow some low-income consumers to be served.

Disadvantages of monopoly:

• Higher prices and lower output: the monopolist restricts output to raise price above the competitive level, reducing consumer welfare.
• Exploitation of consumers through high prices and, sometimes, poor quality.
• Inefficiency (X-inefficiency): lack of competition removes the pressure to keep costs low.
• Loss of consumer choice since there is only one supplier.
• Price discrimination can charge some buyers more for the same good.
• Possible poor service and slower innovation where the firm feels no competitive threat.
