Monopolistic competition differs from pure competition and pure monopoly in several ways.
In pure competition, there are many buyers and sellers, homogeneous products, perfect information, and ease of entry or exit into the market. This means that no individual firm has control over the market price, and each firm is a price taker. In monopolistic competition, on the other hand, there are still many buyers and sellers, but each firm differentiates its product in some way to make it unique or distinct from its competitors. This product differentiation may be achieved through branding, quality, features, location, or any other factor that makes the product appealing to consumers. Additionally, there may be some control over the market price, as firms can exercise some influence over price due to the perceived uniqueness of their products.
In pure monopoly, there is only one seller in the market, and they have complete control over the price. There are significant barriers to entry, such as patents, licenses, or economies of scale, which prevent other firms from entering the industry. This lack of competition allows the monopolist to set the price at a level that maximizes their profit.
Product differentiation in monopolistic competition refers to the process of making a firm's product different from competing products in the market. This differentiation may involve various strategies, such as introducing unique features, offering different packaging or branding, focusing on superior customer service, or using effective advertising and marketing techniques. The goal of product differentiation is to make the firm's product stand out and create a perception of uniqueness in the minds of consumers. This, in turn, allows firms to have some degree of control over the price and demand for their product.
The entry of new firms into a monopolistically competitive industry affects the demand curve faced by existing firms. When new firms enter the market, they offer alternative products that are similar to those already available. This increases the number of substitutes for consumers, reducing the demand for each firm's product. As a result, the demand curve facing a monopolistic competitor becomes more elastic (flatter), indicating that consumers are more responsive to price changes. With more substitutes available, consumers have options and can easily switch to another firm's product if the price becomes less favorable.
The effect of this increased competition on economic profit depends on the extent of product differentiation and the strength of consumer preferences for unique products. If the firm has developed strong brand loyalty or has distinctive features that consumers value, the impact of new entrants may be limited, and the firm can maintain higher prices and earn positive economic profit. However, if the new entrants offer highly similar or better products, the demand for the existing firm's product may decline significantly, leading to a decrease in economic profit or even losses. In response, the monopolistic competitor may need to adjust its pricing, advertising, or product features to retain customers and differentiate from competitors.
