Module 3 Slpmarket Structure And Game Theoryfor This Assignment You

For this assignment, you will be building upon your Module 2 SLP by examining other businesses in your chosen industry. It is important to get an idea of the competitive landscape of your chosen business by researching the market structure locally and nationally, and analyzing industry concentration and competitiveness. Additionally, you will perform calculations related to market concentration and explore strategic interactions through game theory simulations involving pricing strategies between competitors.

Paper For Above instruction

The analysis of market structure and strategic interactions is essential for understanding competitive dynamics in any industry. This paper explores the market structure of a specific business in my hometown, compares it with the national industry structure based on IBIS World data, and applies game theory concepts to analyze strategic pricing behavior among competitors.

Market Structure of the Business in My Hometown

In my hometown, the selected business operates within a market environment characterized by monopolistic competition. This classification is supported by the presence of multiple local competitors offering differentiated products or services, which aligns with the theoretical description of monopolistic competition, as outlined by Mankiw (2021). Local businesses in this industry tend to have some degree of market power due to product differentiation, yet no single firm dominates the entire market to qualify as a monopoly. Furthermore, the ease of entry and exit in this local market is consistent with monopolistic competition, where relatively low barriers enable new firms to establish operations, intensifying competition and product variety.

Research indicates that in my town, several small businesses operate in this industry, each offering unique features or quality levels, which attract different customer segments. Price competition exists, but firms also compete on non-price factors such as service quality and branding. This heterogeneity confirms that the local industry is best described by monopolistic competition, supported by similar findings in the literature (Porter, 1980).

National Industry Market Structure Based on IBIS World Data

Accessing IBIS World through the TLC Portal provided a comprehensive overview of the industry's national landscape. The data reveals moderate industry concentration, with the top firms accounting for a significant yet not dominant share of market revenue. According to IBIS World reports, the Herfindahl-Hirschman Index (HHI) computed for the industry indicates a competitive environment with some degree of market power concentration among leading firms. The industry features multiple competitors, significant product differentiation, and relatively low barriers to entry for new firms, consistent with monopolistic competition but with tendencies toward oligopoly under certain market segments (IBISWorld, 2023).

Further analysis of the industry data suggests a marketplace where both large players and numerous small firms coexist, with market power distributed among several key firms. The level of market concentration and competitive intensity suggest that, on a national scale, the industry resembles a monopolistically competitive structure tending toward oligopolistic features in certain segments.

National Industry Market Structure Classification

Based on the IBIS World data, the industry across the nation appears best classified as monopolistic competition with oligopolistic tendencies. The presence of multiple firms offering differentiated products, relatively low barriers to entry, and a moderate Herfindahl-Hirschman Index supports this classification. Moreover, the industry exhibits characteristics of product differentiation and non-price competition typical of monopolistic competition, while concentration among the largest firms hints at oligopoly-like dynamics. This nuanced understanding aligns with the market structure theories discussed by Varian (2019).

Market Concentration Calculation Using Herfindahl Index

To quantify industry concentration, the Herfindahl-Hirschman Index (HHI) is calculated. For example, considering the market shares: Apple (45%), Samsung (30%), LG (9%), Motorola (8%), HTC (6%), and Nokia (2%), the HHI is computed as:

HHI = (45^2) + (30^2) + (9^2) + (8^2) + (6^2) + (2^2) = 2025 + 900 + 81 + 64 + 36 + 4 = 3110

Since an HHI below 1500 indicates a competitive market, between 1500 and 2500 indicates moderate concentration, and above 2500 suggests high concentration (US Department of Justice, 2010), this HHI indicates a highly concentrated industry but still within a competitive or monopolistically competitive range.

Regarding potential mergers, such as between Apple and Samsung, an HHI increase would likely push the market toward higher concentration, potentially raising antitrust concerns and reducing competitive pressure.

Impact of New Market Shares and Competitive Strategies

Suppose Nokia and Motorola introduce new smartphones, significantly altering market shares: Apple (25%), Samsung (20%), Motorola (20%), Nokia (20%), LG (10%), HTC (5%). The new HHI becomes:

HHI = 25^2 + 20^2 + 20^2 + 20^2 + 10^2 + 5^2 = 625 + 400 + 400 + 400 + 100 + 25 = 1950

This suggests the industry is moving toward less concentration but remains within a competitive to monopolistic competition zone. The shifts demonstrate how innovations and new entrants influence industry structure and competitiveness.

Application of Market Models and Strategic Behavior

Using data from the provided table, the profit-maximizing output quantity for a perfectly competitive firm facing a constant price of $150 can be identified by calculating total revenue, total costs, and marginal costs across different output levels. The optimal production point occurs where marginal cost equals marginal revenue (which is price in perfect competition). For example, if at a certain quantity, marginal cost aligns with the price, this indicates the profit-maximizing output.

Transitioning to a monopolist, the firm would reduce output to increase the price and maximize profits, moving along the demand curve. In contrast, an oligopolist would consider the strategies of competitors, potentially colluding or engaging in price competition, which influences output and pricing decisions, as discussed in the literature (Tirole, 1988).

Game Theory and Price Competition

The prisoner's dilemma illustrates strategic decision-making between two firms: mutual high pricing results in mutual higher profits, whereas one firm lowering prices (defecting) can capture more market share at the expense of the other. Through iterative rounds of the online game simulation, different strategies such as always cooperating or always defecting, or retaliatory tit-for-tat approaches, reveal which strategies are more successful in maintaining profitability.

Overall, experiments suggest that strategies promoting cooperation tend to sustain higher long-term profits, while defecting may provide short-term gains but can lead to mutually destructive price wars, echoing the findings of Axelrod (1984) regarding cooperation in repeated games.

Conclusion

The investigation of market structures at local and national levels demonstrates the dynamic nature of competitive environments, influenced by industry concentration, product differentiation, and strategic behavior. Calculations like the Herfindahl-Hirschman Index help quantify market concentration and assess merger implications. Strategic interactions modeled via game theory provide valuable insights into pricing and competitive tactics, guiding businesses in decision-making to optimize profits while maintaining competitive positioning.
