The assignment provides a comprehensive analysis of different market structures—monopoly, duopoly, oligopoly, and monopolistic competition—and their implications for business strategies. In monopolies, a single firm dominates the market with significant control over prices due to high entry barriers and lack of substitutes. Duopolies feature two main competitors whose strategic decisions directly affect each other’s outcomes, often leading to competitive or cooperative behaviors based on game theory principles. Oligopolies consist of a few dominant firms that can collude to set prices or outputs but may also engage in intense competition. Monopolistic competition involves many firms offering differentiated products with some degree of market power due to brand loyalty and product variation. The assignment evaluates how these structures impact pricing strategies, consumer choices, and overall economic efficiency, using theoretical frameworks and real-world examples to illustrate key points.
