The classification of markets by the nature of competition rests mainly on two questions: how many sellers are there, and how similar or different is their product? Answering these two questions for a given market places it into one of four broad categories.

In a market of perfect competition, there are a very large number of small sellers, each offering an identical (homogeneous) product, so that no single seller can influence the market price by their own action alone — each seller is a "price-taker", accepting whatever price the overall market has settled on. Buyers, too, are numerous, and both sides have complete information about prices and products. Markets for many raw agricultural commodities come closest to this model in practice.

In monopolistic competition, there are still a large number of sellers, but each offers a somewhat differentiated version of the product — through branding, packaging, quality differences, or added features — so that each seller has some limited power to set a slightly different price for their own version, without losing all their customers to competitors. Branded consumer goods such as toothpaste, soaps, and readymade garments are typical examples, where many brands compete but each has built up some degree of customer loyalty.

In an oligopoly, there are only a few sellers, each large enough that a pricing or output decision by one seller noticeably affects, and is affected by, the decisions of the others; the sellers are said to be interdependent. Products may be broadly similar (as in cement or steel) or differentiated (as in automobiles or telecom services), but the defining feature is the small number of major players and their close attention to each other's moves.

Finally, in a monopoly, there is a single seller of a product that has no close substitute, giving that seller substantial control over price. Because an unregulated monopoly can potentially charge unfairly high prices or restrict output, monopolies (especially in essential services) are often subject to government regulation to protect consumer interests.

✓Final answer

The four types are perfect competition (very many sellers, identical product, no price control), monopolistic competition (many sellers, differentiated products, limited price control), oligopoly (few sellers, high interdependence), and monopoly (single seller, high price control).
