Kinked Revenue Curve – It is a theory in economics that explains the behaviour of oligopolistic markets, where a few firms dominate the market. It suggests that if one firm raises its prices, its competitors will not follow suit, leading to a loss of market share for the price-raising firm.
Perfect competition - It is a market structure in which many small firms compete with each other to sell homogeneous products to a large number of buyers. In this type of market, no single firm has significant market power, and each firm is a price taker, meaning that it cannot influence the market price of the product.
Monopolistic Competition - It is a market structure characterized by a large number of small firms that sell similar but not identical products. Each firm has a degree of market power, as it can differentiate its product from its competitors' products through branding, advertising, packaging, or other means
Monopoly- It is a market structure characterized by a single seller who controls the entire market for a particular product or service. This gives the monopolist significant market power, as it can set the price of the product or service without fear of competition.
