12.01-Competitors and Competition

Introduction to Competition

  • Focus: Competitors and competition in business strategies

  • Relation: Ties to microeconomics through industry rivalry

  • Acknowledgment: Not all firms in an industry are direct competitors

Identifying Competitors

  • Importance of understanding competitors to define business strategy

  • Types of Competition:

    • Direct Competition: Strategic choices of one firm directly impact another (e.g., Walmart vs. Target)

    • Indirect Competition: Effects may stem from a third firm's actions (e.g., supplier impacts)

Market Structures

  • Overview of market structures in competition:

    • Perfect Competition: Numerous sellers of homogeneous products

    • Monopolistic Competition: Many sellers but differentiated products

    • Oligopoly: Few sellers with significant market control

    • Monopoly: One seller dominates the market

Department of Justice Guidelines

  • Mergers should not create significant price increases (5% threshold)

  • Competitors include:

    • Firms offering similar products

    • Producers of substitute products (either within or outside the industry)

Characteristics of Substitutes

  • Close substitutes share similar performance and occasions of use

  • Examples:

    • Different types of shoes for specific activities (hiking vs. court shoes)

  • Geographic price differentiation may limit substitutes in certain markets (e.g., cement, housing)

Empirical Approaches to Competitor Identification

  • Cross Price Elasticity of Demand: Positive elasticity indicates that 'y' substitutes 'x'

  • Price Change Patterns: Analyze historical data on price shifts over time

  • Standard Industrial Classification (SIC): Segmentation into codes for data analysis

Market Structure Measures

  • Measurement of market concentration includes:

    • Herfindahl Index: Effective measure for concentration and competition

    • M Firm and N Firm Concentration Ratios: Focus on the relative size of firms

    • Herfindahl ranges help determine competition level

Types of Market Structures Explained

  • Perfect Competition: Many sellers, homogeneous products, price elasticity, free entry/exit

  • Monopolistic Competition: Differentiated products creating competition based on unique features (e.g., dry cleaners, restaurants)

  • Oligopoly: Small number of firms (e.g., airlines or car manufacturers) influencing each other’s prices

    • Duopoly: Only two firms present in the market structure

    • Monopoly: One firm controlling supply and prices, faces limited competition from fringe firms

Dynamics of Price Competition

  • In oligopolies, heavy price competition is common, especially when buyers have good alternatives

  • Excess capacity can lead to price drops and competitive pressure in industries

    • Many sellers may engage in price cutting strategies to attract customers

    • Firms maintain revenue through new customer acquisition or switching from competitors

Monopoly Characteristics

  • Monopolists have pricing power and face little competition

  • Pricing Mechanism: Setting price where marginal revenue equals marginal cost, often above competitive pricing

  • Antitrust Concerns: Monopolization may lead to consumer harm, but efficiencies and innovations can also benefit consumers

Innovation and Consumer Impact

  • Monopolists may drive innovation leading to better product variations and lower costs over time

  • Restricting monopolist profits might hinder innovation and reduce consumer benefits in the long term

Conclusion

  • Recap of competition dynamics in various market structures

  • Importance of strategic awareness in competitor analysis and market conditions
