MARKET STRUCTURE: The manner in which a market is organized, based largely on the number of firms in the industry. The four basic market structure models are: perfect competition, monopoly, monopolistic competition, and oligopoly. The primary difference between each is the number of firms on the supply side of a market. Both perfect competition and monopolistic competition have a large number of relatively small firms selling output. Oligopoly has a small number of relatively large firms. And monopoly has a single firm.

A principle of classical economics developed the French economist Jean-Baptiste Say that is commonly summarized as "supply creates its own demand." This law, also referred to as Say's "theory of markets" or "law of markets," indicates that the act of producing aggregate output generates a sufficient amount of aggregate income to purchase all of the output produced. This principle indicated that excess production or insufficient demand for production was unlikely to occur, at least for any extended period. When combined with flexible prices and saving-investment equality, Say's law further implied that an economy would achieve and maintain full employment of resources. This law was singled out by John Maynard Keynes in his critique of classical economics, but remains relevant in current macroeconomic analysis, reflected in the circular flow model.
