Why analyze a firm’s decisions under conditions of perfect competition?<\/h2>\n

This module is the second in the theory of the firm and the first of three modules examining models of market structure. Market structure means, in a nutshell, how competitive or monopolistic is a particular industry. It should be clear that market structure influences how firms behave. Figure 1 shows the full spectrum of types of markets, from perfect competition with many firms, to a monopoly, with one firm controlling the marketplace.<\/p>\n
