Matching the market structures with their characteristics:
– Perfect competition (A): Characterised by many producers selling identical or similar products (homogeneous) and free entry/exit. This matches Characteristic 4 (Many producers selling similar products).
– Monopoly (B): Characterised by a single producer selling a unique product with high barriers to entry. This matches Characteristic 1 (Only one producer selling one commodity).
– Monopolistic competition (C): Characterised by many producers selling differentiated products and relatively easy entry/exit. This matches Characteristic 3 (Many producers selling differentiated products).
– Oligopoly (D): Characterised by a few producers selling similar or differentiated products with significant barriers to entry. This matches Characteristic 2 (Few producers selling similar or almost similar products).
Thus, the correct match is A-4, B-1, C-3, D-2.
– Perfect competition: Many firms, homogeneous product, free entry.
– Monopoly: Single firm, unique product, high barriers.
– Monopolistic competition: Many firms, differentiated product, low barriers.
– Oligopoly: Few firms, homogeneous or differentiated product, high barriers.
These market structures represent different degrees of competition, ranging from perfect competition (most competitive) to monopoly (least competitive). Real-world markets often fall somewhere between these ideal types.
