Solution:In an oligopoly market structure, a small number of large firms dominate the market. In the case of the mobile phone operators market in India, there are a few major players such as Jio, Airtel, Vodafone, and Idea, who control a significant portion of the market share. These firms have a significant influence over the pricing and output decisions, and they often compete on factors such as network coverage, pricing plans, and customer service.
A market situation where a large number of buyers and sellers deal in a homogeneous product at a fixed price set by the market is known as Perfect Competition. Homogeneous goods are goods of similar shape, size, quality, etc. In other words, in a perfectly competitive market, the
sellers sell homogeneous products at a fixed price determined by the industry and not by a single firm.
In the real world, the situation of perfect competition does not exist; however, the closest example of a perfect competition market is agricultural goods sold by farmers. Goods like wheat, sugarcane, etc., are homogeneous in nature and their price is influenced by the market.
Monopoly is a completely opposite form of market and is derived from two Greek words, Monos (meaning single) and Polus (Meaning seller).
A market situation where there is only one seller in the market selling a product with no close substitutes is known as Monopoly. For
example, Indian Railways. In a monopoly market, there are various restrictions on the entry of new firms and exit of existing firms. Also, there are chances of Price Discrimination in a Monopoly market.
A Monopolistic Competition Market consists of the features of both Perfect Competition and a Monopoly Market. A market situation in which there is a large number of firms selling closely related products that can be differentiated is known as Monopolistic Competition. The
products of monopolistic competition include toothpaste, shampoo, soap, etc.
For example, the market for soap enjoys full competition from different brands and has freedom of entry showing the features of a perfect competition market. However, every soap has its own different
features, which allows the firms to charge a different price for them. It shows the features of a Monopoly Market.
