The company that I am focusing on is Apple iPhones. What are the main companies in the industry? What is the level of market concentration in the industry? To what extent are the products/services from this industry homogenous? How would you characterize the barriers to entry in this industry? How would you characterize the market structure of this industry (perfect competition, monopolistic competition, oligopoly or monopoly)? How does the market structure affect the business strategy and performance of Apple? To what extent may the market structure in this industry lead firms to engage in anticompetitive behaviors?
