3.8 Market Structure
3.8.1 Competitive Markets
- Definition: Market with many buyers and sellers, no single firm can control price.
- Firms compete mainly through price, quality, and service.
Characteristics:
- Many small firms.
- Freedom of entry/exit.
- Prices determined by demand and supply.
- Products often similar but may have some differentiation.
- Firms earn normal profit (little pricing power).
Advantages:
- Lower prices (competition keeps prices down).
- Greater choice for consumers.
- Higher efficiency (firms cut waste, reduce costs).
- Innovation to attract customers.
Disadvantages:
- Small firms may struggle to survive.
- Profits are low → less money for research and development.
- Quality may be sacrificed in price wars.
Examples: Street food markets, retail shops, agriculture (vegetables, fruits).

Advantages:
- Economies of scale → lower average costs.
- Stability in supply and prices.

- Natural monopolies may be more efficient than having many small firms (e.g., electricity supply).
Disadvantages:
- Higher prices for consumers (less competition).
- Less choice.
- Risk of inefficiency (lack of competitive pressure).
- Potential exploitation of consumers and workers.
Examples:
- Microsoft (software dominance in the 1990s).
- State-owned electricity and water utilities.
