💹Business Economics Unit 6 – Market Structures & Pricing Strategies

Key Concepts

• Market structures categorize industries based on characteristics such as the number of firms, barriers to entry, and product differentiation
• Pricing strategies involve setting prices for goods or services to maximize profits while considering factors like demand, competition, and production costs
• Market power refers to a firm's ability to influence the price of its products or services in the market
• Profit maximization occurs when a firm produces the quantity of output where marginal revenue equals marginal cost ($MR = MC$)
• Barriers to entry are obstacles that make it difficult for new firms to enter a market (high startup costs, government regulations, patents)
• Product differentiation distinguishes a firm's products from competitors through unique features, branding, or quality
• Elasticity of demand measures the responsiveness of quantity demanded to changes in price
  • Elastic demand: quantity demanded changes significantly with price changes
  • Inelastic demand: quantity demanded is relatively insensitive to price changes

Types of Market Structures

• Perfect competition: many small firms, homogeneous products, no barriers to entry, no market power
• Monopoly: single firm, unique product, high barriers to entry, significant market power
• Oligopoly: few large firms, interdependent decision-making, high barriers to entry, some market power
• Monopolistic competition: many firms, differentiated products, low barriers to entry, some market power
• Each market structure has distinct characteristics that influence firm behavior and market outcomes
• The degree of competition and market power varies across different market structures
• Market structures can change over time due to technological advancements, changes in consumer preferences, or government interventions

Perfect Competition

• Large number of small firms producing identical products
• Firms are price takers, meaning they have no control over the market price
• Free entry and exit of firms in the long run
• Perfect information about prices and products for both buyers and sellers
• Firms aim to maximize profits by producing where $MR = MC$
• In the long run, economic profits are driven to zero due to the entry of new firms
• Efficient allocation of resources as firms produce at the lowest possible cost
• Firms in perfect competition face a perfectly elastic demand curve

Monopoly

• Single firm producing a unique product with no close substitutes
• High barriers to entry (economies of scale, legal barriers, control over essential resources)
• Monopolist is a price maker and has significant market power
• Faces a downward-sloping demand curve, meaning it can set prices above marginal cost
• Profit maximization occurs where $MR = MC$, but the price is set above marginal cost
• May engage in price discrimination to capture more consumer surplus
• Inefficient allocation of resources as the monopolist produces less than the socially optimal quantity
• Government regulations (antitrust laws, price controls) aim to prevent monopolies from abusing their market power

Oligopoly

• Few large firms dominate the market, producing either homogeneous or differentiated products
• High barriers to entry (economies of scale, legal barriers, high startup costs)
• Firms are interdependent and consider rivals' actions when making decisions
• Engage in strategic behavior (price leadership, collusion, price wars)
• Kinked demand curve model explains price rigidity in oligopolies
  • Firms are reluctant to change prices due to the anticipated reactions of competitors
• Collusion among firms can lead to higher prices and reduced output, harming consumers
• Game theory is used to analyze the strategic interactions among oligopolistic firms

Monopolistic Competition

• Many firms producing differentiated products with close substitutes
• Low barriers to entry and exit
• Firms have some market power due to product differentiation
• Engage in non-price competition (advertising, branding, product innovation)
• Profit maximization occurs where $MR = MC$, but firms can set prices above marginal cost in the short run
• In the long run, economic profits are driven to zero due to the entry of new firms
• Inefficient allocation of resources as firms operate with excess capacity
• Examples include restaurants, clothing retailers, and beauty salons

Pricing Strategies

• Cost-plus pricing: adding a markup to the cost of production to determine the selling price
• Penetration pricing: setting a low initial price to attract customers and gain market share
• Skimming pricing: setting a high initial price to capture the consumer surplus of early adopters
• Predatory pricing: setting prices below cost to drive competitors out of the market
• Price discrimination: charging different prices to different customers based on their willingness to pay
  • First-degree: charging each customer their maximum willingness to pay
  • Second-degree: offering quantity discounts or versioning
  • Third-degree: segmenting the market based on observable characteristics (age, location)
• Bundling: selling multiple products together as a package
• Psychological pricing: using prices that appear more attractive to consumers ($9.99 instead of$10)

Real-World Applications

• Analyzing market structures helps businesses make informed decisions about pricing, production, and investment
• Antitrust laws (Sherman Act, Clayton Act) prevent monopolies and anticompetitive practices
• Natural monopolies (utilities, telecommunications) are regulated to ensure fair prices and access
• Oligopolistic markets (airlines, smartphones) often exhibit price rigidity and non-price competition
• Monopolistic competition is prevalent in industries with low barriers to entry and differentiated products (restaurants, hair salons)
• Price discrimination is common in industries with high fixed costs and low marginal costs (software, airlines)
• Predatory pricing allegations have been made against large companies like Amazon and Walmart
• Bundling is often used by telecommunications companies (cable TV, internet, phone) and in the software industry (Microsoft Office)
