Answer :-
Theory of monopoly :-
Monopoly is a market structure in which there is only one supplier of a product.
Characteristics of a monopoly:
May be small or large, only one supplier of the product, and sells a product where there are no close substitutes.
Natural monopoly is monopoly that arises from economies of scale.
Rivalry :-
Rivalry is the threat that firms will compete away profit margins. Rivalry occurs through:
1. Price competition
2. Frequent intro of new products
3. Intense advertising
4. Fast competitive response
5. Exit barriers
Sources of increasing rivalry;
1. Large number of competing firms of similar size
2. Lack of product differences
3. Slow industry growth
4. Fixed costs are a significant fraction of total costs
5. Production capacity added in large increments.
Greatest threat to performance is for rivals to dissipate economic profits through price competition.
Oligopoly :-
Oligopoly is a market structure in which a small number of interdependent firms compete.
It is a market structure in which a few large firms dominate a market; barriers to entry, cooperation, collusion and cartels.
Characteristics/ Key Features:
1) Few Sellers in the Industry
2) Interdependence Between Firms
3) Product Differentiation Occurs
4) Barriers to Entry Exist
5) Collusion May Occur
6) Non-price Competition is More Common than Price Competition.
Barriers to entry exist these are common in oligopolistic markets as existing firms wish to maintain their market share. E.g. High start-up costs or Brand proliferation.
Monopolistic competition :-
Monopolistic Competition is a market structure in which a large number of firms compete.Each firm produces a differentiated product.Firms compete on price, product quality, and marketing.Firms are free to enter and exit.
Characteristics of monopolistic competition:
1)Many small buyers and sellers
2)Freedom of entry and ext
3)Perfect information
4)Slightly different (heterogenous products)
It is to be noted that 1-3 match up with perfect competition but in perfect competition products are perfect substitutes.
Efficiency of monopolistic competition:
Not very efficient because they usually do not produce at the minimum average cost.
