Part 3- Economics: Market Structures Overview

Monopolistic Competition

• Differentiates products: Firms sell unique goods or services to appeal to specific customer preferences.
• Example: Cafés in an area compete with unique menus and atmospheres.
• Profit maximization: Achieved when marginal revenue equals marginal cost.
• Pricing power: Firms have some control over pricing due to differentiated products.
• Example: Clothing brands offer unique products which influence consumer choice.

Oligopoly

• Few dominant firms: Market controlled by a limited number of large companies.
• Interdependence: Companies' actions impact each other, like price changes.
• Example: Airline industry, where pricing strategies are influenced by competitors.

Monopoly

• Single supplier: One company controls the entire market for a product or service.
• Downward sloping demand curve: Reduce prices to sell more units.
• Example: Regional water utility provider has a monopoly in their area.

Perfect Competition

• Homogeneous products: All firms sell identical goods or services.
• Price takers: Firms cannot set prices and must accept the market rate.
• Example: Wheat or raw cotton from different suppliers are virtually the same.
• Free entry and exit: No barriers for new firms to enter or existing firms to leave.
• Example: Agricultural markets, where farmers can enter or exit based on profitability.

Market Structures

• Monopoly: High barriers to entry, price setting power.
• Oligopoly: High barriers to entry, interdependent firms.
• Monopolistic Competition: Low barriers to entry, some pricing power.
• Perfect Competition: No barriers to entry, no pricing power.

Key Takeaways

• Product differentiation: Key factor in monopolistic competition, driving firms to offer unique goods and services.
• Interdependence: Crucial characteristic of oligopolies, leading to careful consideration of competitors' responses.
• Pricing power: Monopolies have the highest pricing power, while perfectly competitive firms are price takers.
• Barriers to entry: Influence the level of competition in each market structure.
• Market dynamics: Entry and exit of firms are influenced by factors like profitability and barriers to entry.

Monopolistic Competition

• Many firms selling differentiated products
• Firms can cater to specific customer preferences through quality, branding, or customer service
• Example: Cafés in the same area offer unique menus and atmospheres

Oligopoly

• Few firms are independent
• One firm’s actions affect other firms
• Example: Airline industry

Monopoly

• Single firm controls the supply of a product
• The demand curve slopes downwards, meaning to sell more, the monopolist must lower its price
• Example: Regional water utility provider

Perfect Competition

• Firms sell identical products with no distinction
• Firms are "price takers"
• Example: Wheat or cotton from different suppliers

Monopolistic Competition Profit Maximization

• Firms maximize profit when marginal revenue equals marginal cost
• Firms have control over pricing due to differentiated products
• Example: Clothing brands offer a unique product

Perfect Competition vs. Monopolistic Competition

• Monopolistic competition: Firms offer differentiated products and have pricing power
• Perfect competition: Firms sell identical products and are price takers

Oligopoly Characteristics

• Smartphone market dominated by Apple and Samsung
• Companies respond to each other's product launches and pricing strategies

Monopoly Existence

• Single firm has complete control over a product’s supply
• No direct competitors
• Example: Regional electricity suppliers

Market Structure with No Barriers to Entry

• Perfect competition
• Farmers can enter or exit the market based on crop prices and profitability

Oligopoly Firm Behavior

• Firms closely watch competitors’ actions and adjust prices accordingly
• Example: Airlines respond to competitors’ fare adjustments

Monopolistic Competition Firm Behavior

• Firms have pricing power due to unique products
• Example: Each café in a city may set different prices for coffee based on brand, location, and quality

Natural Monopoly

• One firm can supply the entire market at a lower cost than multiple suppliers
• Example: Public utilities, like water companies

Perfect Competition Price Setting

• Firms cannot set prices.
• If they charge more than the market price, consumers will buy from competitors offering the same product at the market rate
• Example: Grains

Least Affected by Pricing Decisions

• Perfect competition because firms cannot influence the market price due to many firms selling identical products.

Barriers to Entry in Oligopoly

• High barriers prevent new firms from entering easily
• Existing firms have brand loyalty and economies of scale
• Example: Automobile Industry

Highest Price Setting Power

• Monopoly
• Example, Local water utility

Company with Sole Provider of Public Utility

• Monopoly
• Example: Electricity or water services

Monopolistic Competition Product Differentiation

• Gives firms some pricing power
• Example: Shampoo brands are marketed with unique benefits

Least Important Product Differentiation

• Perfect competition
• Products are identical: grains
• Firms compete on price

Entering and Exiting Monopolistic Competition Market

• Low entry barriers allow firms to enter and exit the market based on profit opportunities
• Example: Restaurants
