In economics, market structure is a descriptive organizational term for discussing the economics of the market and other characteristics of a market.

History

Market structure has historically emerged in two separate types of discussions in economics, that of Adam Smith on the one hand, and that of Karl Marx on the other hand. Adam Smith in his writing on economics stressed the importance of laissez-faire principles outlining the operation of the market in the absence of dominant political mechanisms of control, while Karl Marx discussed the working of the market in the presence of a controlled economy sometimes referred to as a command economy in the literature. Both types of market structure have been in historical evidence throughout the twentieth century and twenty-first century.

Types

The discussion of market structure in free economies as described by Adam Smith is often qualified or discussed in terms of patterns of market organization which serve the buyers and sellers in any particular form of the marketplace. Some types of market structure may be described using several recurrent types of descriptive organizational mechanism which may or may not dominate any particular market over time or at particular points in time, such as;

1. Monopolistic competition, a type of imperfect competition such that many producers sell products or services that are differentiated from one another (e.g. by branding or quality) and hence are not perfect substitutes. In monopolistic competition, a firm takes the prices charged by its rivals as given and ignores the impact of its own prices on the prices of other. This market structure exists when there are multiple sellers who are attempting to seem different than each other.

2. Oligopoly, in which a market is run by a small number of firms that together control the majority of the market share.

  • Duopoly, a special case of an oligopoly with two firms.
  • Monopsony, when there is only a single buyer in a market.
  • Oligopsony, a market where many sellers can be present but meet only a few buyers.

3. Monopoly, where there is only one provider of a product or service.

  • Natural monopoly, a monopoly in which economies of scale cause efficiency to increase continuously with the size of the firm. A firm is a natural monopoly if it is able to serve the entire market demand at a lower cost than any combination of two or more smaller, more specialized firms.

4. Perfect competition, a theoretical market structure that features low barriers to entry, identical products with no differentiation, an unlimited number of producers and consumers, and a perfectly elastic demand curve.[1]

Elements and concerns

The imperfectly competitive structure is quite identical to the realistic market conditions where some monopolistic competitors, monopolists, oligopolists, and duopolists exist and dominate the market conditions. The elements of Market Structure include the number and size distribution of firms, entry conditions, and the extent of differentiation.

These somewhat abstract concerns tend to determine some but not all details of a specific concrete market system where buyers and sellers actually meet and commit to trade. Competition is useful because it reveals actual customer demand and induces the seller (operator) to provide service quality levels and price levels that buyers (customers) want, typically subject to the seller's financial need to cover its costs. In other words, competition can align the seller's interests with the buyer's interests and can cause the seller to reveal his true costs and other private information. In the absence of perfect competition, three basic approaches can be adopted to deal with problems related to the control of market power and an asymmetry between the government and the operator with respect to objectives and information: (a) subjecting the operator to competitive pressures, (b) gathering information on the operator and the market, and (c) applying incentive regulation.[2]

Quick Reference to Basic Market Structures
Market Structure Seller Entry Barriers Seller Number Buyer Entry Barriers Buyer Number
Perfect Competition No Many No Many
Monopolistic competition No Many No Many
Monopoly Yes One No Many
Duopoly Yes Two No Many
Oligopoly Yes Few No Many
Monopsony No Many Yes One
Oligopsony No Many Yes Few

The correct sequence of the market structure from most to least competitive is perfect competition, imperfect competition, oligopoly, and pure monopoly.

The main criteria by which one can distinguish between different market structures are: the number and size of producers and consumers in the market, the type of goods and services being traded, and the degree to which information can flow freely.
