6.3 Pricing Strategies and Market Power

Pricing strategies and market power are crucial concepts in understanding how firms compete and maximize profits. These tools allow companies to set prices based on consumer behavior, market conditions, and their own market position.

From price discrimination to predatory pricing, businesses use various tactics to gain an edge. Understanding these strategies helps explain why prices differ across markets and how firms maintain their competitive advantage.

• Market power enables firms to influence market prices by controlling significant market share or possessing unique advantages
• Measure market power using indicators
  • Lerner Index quantifies a firm's ability to price above marginal cost
  • Herfindahl-Hirschman Index (HHI) assesses market concentration
• Firms with market power set prices above marginal cost resulting in higher profit margins
• Sources of market power include
  • Economies of scale (large-scale production efficiencies)
  • Network effects (value increases with user base, Facebook)
  • Brand loyalty (customer preference for established brands, Apple)
  • Legal barriers to entry (patents, licenses)

Impact of Market Power on Pricing and Demand

• Market power significantly influences pricing decisions
  • Allows for strategies not feasible in competitive markets (premium pricing)
• Affects demand elasticity faced by firms
  • Greater market power generally results in less elastic demand
  • Consumers have fewer alternatives, less sensitive to price changes
• Regulatory bodies monitor markets with substantial market power
  • Prevent abuse and maintain fair competition
  • Examples include antitrust laws and merger reviews

Pricing Strategies: A Comparison

Price Discrimination Techniques

• Price discrimination charges different prices to consumers for the same product based on willingness to pay
• Three degrees of price discrimination
  1. First-degree (perfect price discrimination): Charge each consumer their maximum willingness to pay
  2. Second-degree (quantity discounts): Offer lower prices for larger quantities purchased
  3. Third-degree (market segmentation): Divide consumers into groups and charge different prices (student discounts)
• Dynamic pricing adjusts prices in real-time based on demand fluctuations (airline tickets, ride-sharing services)
• Bundle pricing combines multiple products into discounted packages (cable TV and internet bundles)

Competitive and Market Entry Strategies

• Predatory pricing sets prices below cost to eliminate competitors
  • Intention to raise prices once competition is eliminated
  • Example: Amazon's aggressive pricing in its early years
• Penetration pricing sets low initial prices to gain market share quickly
  • Often used for new product launches (streaming services introductory rates)
• Skimming pricing sets high initial prices to maximize profits from early adopters
  • Common in technology markets (new smartphone models)
• Loss leader pricing uses heavily discounted items to attract customers
  • Expectation of profiting from additional purchases
  • Example: Discounted game consoles to sell more games

Welfare Effects of Pricing

Consumer and Producer Surplus Analysis

• Consumer surplus measures difference between willingness to pay and actual price paid
  • Indicates consumer welfare
  • Example: Paying $80 for a product valued at$100, resulting in $20 consumer surplus
• Producer surplus represents difference between market price and minimum acceptable price
  • Indicates producer welfare
  • Example: Selling a product for $80 when willing to accept$60, resulting in $20 producer surplus
• Price discrimination impacts welfare
  • Can increase total welfare by serving price-sensitive consumers
  • May reduce consumer surplus by capturing more value for producers

Long-term Market Effects and Regulation

• Predatory pricing initially benefits consumers through lower prices
  • May lead to reduced competition and higher prices long-term
  • Example: Local store closures due to big-box retailer price wars
• Dynamic pricing improves market efficiency by matching supply and demand
  • Can be perceived as unfair by consumers (surge pricing during emergencies)
• Bundling welfare effects depend on consumer preferences
  • Can increase or decrease total welfare based on market conditions
• Regulatory interventions aim to protect consumer welfare
  • Price ceilings or floors may have unintended consequences
  • Example: Rent control leading to housing shortages

Market Power and Firm Performance

Profitability and Competitive Advantage

• Market power allows firms to maintain prices above marginal cost
  • Leads to economic profits in the long run
  • Example: Apple's premium pricing in the smartphone market
• Creates barriers to entry protecting incumbent firms
  • Sustains profitability by limiting new competition
  • Example: High costs of entering the pharmaceutical industry
• Enables investment in research and development
  • Potentially leads to innovation and long-term sustainability
  • Example: Google's diverse portfolio of experimental projects

Sustainability and Risks of Market Power

• Market power helps firms weather economic downturns
  • Ability to adjust prices and output to maintain profitability
• Sustainability of market power depends on various factors
  • Strength of network effects (social media platforms)
  • Brand loyalty (luxury goods markets)
  • Adaptability to changing market conditions
• Excessive market power can lead to complacency
  • Reduced efficiency harming long-term sustainability
  • Example: Kodak's failure to adapt to digital photography
• Regulatory scrutiny poses risks to firms with significant market power
  • Potential antitrust actions impact profitability and sustainability
  • Examples include Microsoft's antitrust case in the 1990s and recent scrutiny of tech giants
