Market structures
Market structures refer to the various characteristics of an economic environment in which businesses operate, influencing how firms compete, set prices, and interact with consumers. There are four primary types of market structures: perfect competition, monopolistic competition, monopoly, and oligopoly. In perfect competition, numerous small firms sell identical products, with no single firm able to influence market prices. Monopolistic competition features many companies selling differentiated products, allowing them to set their own prices, albeit at the cost of market efficiency.
A monopoly exists when a single company dominates the market without any close substitutes, granting it significant pricing power. Finally, an oligopoly consists of a few large firms that hold substantial market shares, where companies may sell identical or differentiated products and must consider the actions of their competitors when making pricing and production decisions. Understanding these market structures helps to grasp the dynamics of competition and consumer choice within different industries.

Market structures
Market structure refers to the characteristics of an economic environment in which businesses operate. The characteristics may include factors such as product differentiation, product demand and utilization, market entry requirements, pricing power, and the types and extent of industry competition. There are four basic types of market structure. In perfect competition, numerous small companies with the same product compete against each other. In monopolistic competition, many companies with slightly different products compete with one another. In a monopoly, one company operates with no direct competition. An oligopoly structure occurs in markets where only a few companies compete.
Overview
Perfect competition is a market structure in which many companies sell identical products and any seller can enter or exit the market freely. In perfect competition, each seller represents only a tiny portion of the total market so no individual firm can set the market price for the product. That price is set by supply and demand. The product itself is standardized across the market, meaning that there is no differentiation by company; each firm’s product can serve as a substitute for another firm’s product. With no barriers to entry and exit, there is no possibility of achieving economies of scale, which are the cost advantages achieved when per-unit expenses are shared across higher quantities of product output.
Perfect competition is viewed as the most efficient market structure within any given stable market environment, producing the maximum benefit for the least cost. Other market structures provide long-term advantages over perfect competition, including consumer choice and economies of scale.
Monopolistic competition is similar to perfect competition in that there are many companies and market entry is easy. The key difference is that companies in monopolistic competition sell differentiated products—for which they can set their own prices—that are close substitutes for a competitor’s goods but are not identical to them. The differentiation increases consumer choice but the higher prices set by companies for their own products reduce overall efficiency as a result of lower total output.
Monopoly occurs when there is only one company supplying the entire market with a product that has no close substitutes. Consumers have no choice of product, and the providing company has all the market power. The company determines the selling price for its product and the quantity of product that it will offer for sale. Higher prices will usually result in fewer sales, meaning that a company in a monopoly market will sell a lower quantity of product at a higher price than companies in other types of market structures.
Monopolies are possible because the barriers to market entry prevent other firms from entering the sector. With other firms unable to enter the market to compete, it is possible for companies in a monopoly market to earn profits over the long term.
The characteristics that distinguish oligopoly from other market structures include a few relatively large companies and difficult market entry. Products may be identical or differentiated. In an oligopoly, companies have some control over product pricing, although there is a large degree of interdependence given that each player holds a large share of the market and must act accordingly in order to maintain market share and profits. Companies in an oligopoly continually try to stay ahead of the competition through innovation and improvements designed to lure customers.
