Economics Chapter 7 - Market Structures

Study Notes

Market Structures Overview

Perfect competition entails many firms producing identical products.
Imperfect competition occurs when market conditions do not meet perfect competition standards.

Conditions for Perfect Competition

Numerous buyers and sellers ensure market activity.
Products must be identical, facilitating easy consumer choice.
All participants should be well-informed on prices and products.
Free entry and exit from the market allows for healthy competition.

Key Concepts in Market Structures

Commodity: A uniform product like milk or petroleum, irrespective of producer.
Barrier to Entry: Factors impeding new firms from entering a market, such as start-up costs or technology.

Types of Market Structures

Monopoly: Exclusive control by a single seller, restricting competition.
- Conditions include one firm, no variety in goods, and complete barriers to entry with price control.
Monopolistic Competition: Many firms offering similar but differentiated products, allowing some price control.
Oligopoly: A few large firms dominate the market with high entry barriers and some control over prices.

Market Dynamics

Economies of Scale: Reduction in average costs per unit as production increases.
Natural Monopoly: Best efficiency achieved when one large firm supplies the market.
Government Monopoly: Established and regulated by the government.

Pricing and Competition

Price Discrimination: Charges different prices to different customer groups based on willingness to pay.
Market Power: Companies can set prices and output similarly to monopolists.

Competitive Strategies

Nonprice Competition: Strategies such as physical product differentiation or service quality to attract customers.
Collusion: Agreements among firms to manipulate market conditions (includes price fixing).
Predatory Pricing: Reducing prices below cost to eliminate competition.

Regulatory Framework

Antitrust Laws: Designed to promote market competition and prevent monopolistic practices.
Prominent antitrust cases include the Sherman Anti-Trust Act and the breakup of AT&T.

Corporate Structures

Merger: Combining two or more companies into one entity.
Trust: An illegal grouping of companies to restrict competition.

Deregulation and Its Impacts

Removal of government controls can have mixed results, seen in banking and airlines.
Banking benefits include new services, while challenges stem from financial crises.
Deregulation in airlines led to new entrants, but many eventually failed.

Requirements for a Perfectly Competitive Market

Attendance by many buyers and sellers.
Sellers offering identical products.
Information accessibility for buyers and sellers.
Freedom for sellers to enter and exit the market.

Limitations of Price Discrimination

Requires some market power and identifiable customer groups.
Resale of goods must be challenging for effective discrimination.
