Question 1 — The four market structures
1. Perfect competition
- Definition: Many small firms selling an identical (homogeneous) product; buyers and sellers are price takers.
- Number of firms / product type: Very many firms; identical products.
- Barriers to entry: None (free entry and exit).
- How prices are determined: Market supply and demand set the market price; each firm accepts that price and produces where P = MC (profit max).
- Example industry: Agricultural commodities (e.g., wheat, corn) as a simplified real-world example.
2. Monopolistic competition
- Definition: Many firms selling differentiated products (product differentiation gives some market power).
- Number of firms / product type: Many firms; differentiated products (brands, quality, style).
- Barriers to entry: Low to moderate (relatively easy entry, some brand/advertising advantages).
- How prices are determined: Each firm faces a downward-sloping demand curve and has some pricing power (sets price above MC); in the long run entry erodes economic profit so firms earn zero economic profit.
- Example industry: Restaurants, clothing stores, hair salons.
3. Oligopoly
- Definition: A few large firms dominate the market; firms’ decisions are interdependent.
- Number of firms / product type: Few firms; products may be homogeneous or differentiated.
- Barriers to entry: High (economies of scale, large capital requirements, control of key inputs, legal/regulatory barriers).
- How prices are determined: Strategic interaction matters — prices may be set by tacit or explicit collusion (cartels), by competitive models (Cournot/Bertrand), or be sticky (kinked demand); outcomes can range from near-competitive to monopoly-like pricing depending on behavior.
- Example industry: Commercial airlines, automobile manufacturing, major telecoms, oil majors.
4. Monopoly
- Definition: Single seller supplying a unique product with no close substitutes.
- Number of firms / product type: One firm; unique product.
- Barriers to entry: Very high (legal barriers/patents, exclusive control of essential resources, extreme economies of scale that make a natural monopoly).
- How prices are determined: The monopolist is a price maker — chooses output where MR = MC and sets price from the market demand curve (price > MC); can earn long-run economic profits unless regulated.
- Example industry: Local public utilities (electricity distribution), a patented pharmaceutical during patent life.
