Answer 1

Sr. No.	Feature	Perfect Competition	Monopoly	Monopolistic Competition	Oligopoly
1	Number of Sellers	In a perfect competition market, there are a very large number of sellers.	In a monopoly market, there is only one seller.	In a monopolistic competition market, there are many sellers.	In an oligopoly market, there are a few large sellers.
2	Nature of Product	In a perfect competition market, products are homogeneous and identical.	In a monopoly market, the product is unique with no close substitutes.	In a monopolistic competition market, products are differentiated.	In an oligopoly market, products may be either homogeneous or differentiated.
3	Price Control	In a perfect competition market, a firm is a price-taker with no control over price.	In a monopoly market, the firm is a price-maker with full control over price.	In a monopolistic competition market, firms have partial control over price due to product differentiation.	In an oligopoly market, firms have considerable control over price but are interdependent.
4	Entry and Exit	In a perfect competition market, there is free entry and exit of firms.	In a monopoly market, there are strong barriers to entry.	In a monopolistic competition market, entry and exit of firms are relatively easy.	In an oligopoly market, entry is difficult due to scale economies and barriers.
5	Demand Curve (AR Curve)	In a perfect competition market, the demand curve is perfectly elastic or horizontal.	In a monopoly market, the demand curve is downward-sloping.	In a monopolistic competition market, the demand curve is downward-sloping but more elastic than monopoly.	In an oligopoly market, the demand curve may show kinked or uncertain behavior.
6	Profit in the Long Run	In a perfect competition market, firms earn only normal profit in the long run.	In a monopoly market, the firm can earn supernormal profits in the long run.	In a monopolistic competition market, firms earn only normal profits in the long run.	In an oligopoly market, firms may earn supernormal profits in the long run.
7	Knowledge of Market	In a perfect competition market, buyers and sellers have perfect knowledge.	In a monopoly market, knowledge is imperfect and may be controlled by the firm.	In a monopolistic competition market, knowledge is imperfect because of advertising and branding.	In an oligopoly market, knowledge is imperfect and firms are highly interdependent.
8	Examples:	Examples of perfect competition include wheat and rice (in theory).	Examples of monopolies include Indian Railways and local electricity boards.	Examples of monopolistic competition include toothpaste, soap, and clothing brands.	Examples of oligopolies include automobile companies, airlines, and telecom industries.
