The SCP model dates back to the pioneering work of the Harvard economist Edward Mason, in the 1930s, and one of his doctoral student Joseph Bain, in the 1950s. Originally used by the US government in crafting antitrust policy, the model gained popularity among corporate strategists when Michael Porter (Competitive Strategy, 1980) used it as an analytic tool for businesses striving to compete within a market. The model's original form depicts the influence of an industry's structure (for example, the growth of demand and barriers to entry) on the conduct of producers (pricing, for example) and the performance of both the industry and the producers. You followed all these steps in your report and now it's the time to evaluate the model. What advantages and disadvantages did you find in the SCP model?
