Concept:
In economics, markets are classified based on the degree of competition, number of buyers and sellers, and control over price.
Step 1: Perfect Competition.
- Large number of buyers and sellers
- Homogeneous products
- Free entry and exit
- Price is determined by market forces (no control by individual firms)
Step 2: Monopoly.
- Single seller and many buyers
- Unique product with no close substitutes
- High control over price
- Restricted entry of new firms
Step 3: Monopolistic Competition.
- Large number of sellers
- Differentiated products (branding, quality, features)
- Some control over price
- Free entry and exit
Step 4: Oligopoly.
- Few large firms dominate the market
- Products may be homogeneous or differentiated
- Interdependence among firms
- Entry barriers exist
Step 5: Duopoly.
- Special case of oligopoly with only two sellers
- High competition between two firms
Step 6: Conclusion.
Thus, markets are classified into perfect competition, monopoly, monopolistic competition, oligopoly, and duopoly based on economic characteristics.
