In which market, there is no difference between the industry and the firm ?

Question

Accepted Answer

The correct option is 1:
In a Monopoly market structure, there is fundamentally no distinction between the firm and the industry. This is because a monopoly, by definition, is characterized by a single seller or producer controlling the entire market for a specific good or service that has no close substitutes. Therefore, the single firm *is* the industry itself. Any output decision made by the firm directly affects the total industry output, and any decision regarding price is the market price. The monopolist faces the market demand curve, which reinforces the identity between the firm and the industry.

The incorrect option is 2:
Perfect competition involves numerous small firms, none of which can influence the market price or output individually. In this case, the industry consists of all these numerous firms combined, which is distinct from any single, individual firm.

The incorrect option is 3:
Imperfect competition is a broad term that includes market structures like monopolistic competition and oligopoly. In monopolistic competition, many firms sell differentiated products, and in oligopoly, a few large firms dominate the market. In both scenarios, multiple firms exist, meaning the industry (the collective group of firms) is separate and distinct from any single firm operating within it.

The incorrect option is 4:
Duopoly is a specific type of oligopoly where exactly two firms control the entire market. Since there are two separate firms operating, the collective market (the industry) is composed of both firms, making it distinct from either one of the individual firms.
