Market power is a measure of the ability of a company to successfully influence the pricing of its products or services in the overall marketplace.
Factors influencing Market Power
1. Number of competitors in a market
For a company to hold extensive market power in the industry in which it operates, the industry must not be heavily populated with competition. Market power is inversely related to the number of companies present in the market. Fewer companies mean greater market power is available to each player.
2. Elasticity of demand
For a company to exert market power, there must be inelastic demand for its products. This means that regardless of the price of the product, there is a persistent need for the product. Companies can achieve an inelastic demand curve by providing unique products and services that create value for the customer.
3. Product differentiation
If a company offers differentiated products and services or holds an extensive market share, it can, to some extent, dictate the pricing of its products and meet the inelastic demand from customers. A high degree of pricing power helps a company achieve market power.
4. Ability of companies to make above “normal profit”
In a perfectly competitive market, where buyers and sellers are both price takers, it is not possible to make above-normal profits in the long run. If there is a scenario where companies can make profits above the normal profit range, more companies will join the industry seeking the same, and this will dilute the position of each player and bring down the profits to normal. A company with great market power will be able to make profits above “normal profit.”
5. Pricing power
If a company offers distinguished products and services or holds extensive market share, it can, to some extent, dictate the pricing of its products and meet the inelastic demand from customers. A high degree of pricing power helps a company achieve market power.
6. Perfect information
If an industry enjoys a perfect flow of information and there is no mismatch between facts and information available to sellers, players will not achieve market power.
7. Barriers to entry or exit
If an industry has high barriers to entry, the players typically hold market power. High barriers to entry mean the existing players are protected because new players cannot easily enter to disrupt the marketplace.
8. Factor mobility
If an industry provides equal ease of access to inputs of its products or services, the market power of individual firms will not be better off.
Market Power in Different Market Concentrations
1. Perfect competition
In a perfectly competitive market, multiple sellers sell a standardized product to multiple buyers. There are many sellers in a homogeneous market that can freely exit or enter the market. Barriers to entry do not exist, and companies cannot make above “normal profits” in the long run.
Buyers in a perfectly competitive market will enjoy perfect information regarding the product or service. Since all products in the market are substitutes for one another, the demand for products is extremely elastic. All companies are price takers and hold zero market power.
2. Monopolistic competition
Monopolistic competition is a form of imperfect competition wherein a few sellers control the market by differentiating their products through branding or customization. Because of such traits, the products in the market are not perfect substitutes for each other, and sellers can determine prices.
In the long run, however, the demand becomes elastic as companies eventually modify their products to suit the market’s needs. Barriers to entry do exist, but they may be low. Perfect information is not available to the buyers and sellers; there is an ambiguity to be exploited by a more knowledgeable player. Sellers in a monopolistic market are price setters and hold market power.
In a monopoly, a single company is the sole seller of a distinct type of product or service. The products are not merely customized by a different specialized category in their sphere. Due to the unique nature of the product, the demand remains inelastic, and the company can exercise extensive pricing power and make profits that are above “normal profits.”
The industry is characterized by extremely high barriers to entry, as the existing company may be protected by patents, and the factor mobility does not exist. Buyers are unable to access perfect information, and, in some cases, the sole seller can exploit the market by indulging in price discrimination. A monopolistic firm enjoys extremely high, if not absolute, market power.
