Market Structure
  • The nature and degree of competition among firms in the same industry
perfect competition
Perfect Competition
  • Market structure characterized by a large number of well-informed independent buyers and sellers who exchange identical products.
  • A Theoretical idea

Q: So why does perfect competition serve as a theoretical market structure?

A: Its advantages serve as a yardstick or example for other structures to be measured by.

perfect competition conditions
Perfect Competition Conditions
  • Must be a large number of buyers and sellers
  • Buyers and sellers deal in identical product
  • Each buyer and seller acts independently
  • Buyers and sellers are reasonably well-informed about product and prices
  • Buyers and sellers are free to enter into, conduct, or get out of business
monopolistic competition
Monopolistic Competition
  • Market structure that has all the conditions of perfect competition except for identical products.
  • Seller has the ability to raise or lower the price
  • If sellers raise or lower the price enough, customers will change brands
monopolistic competition1
Monopolistic Competition
  • Characterized by product differentiation: real or perceived differences between competing products in the same industry.
  • To make their products stand out, they use nonprice competition: the use of advertising, giveaways, or other promotions designed to convince buyers that the product is somehow unique or fundamentally better than a competitor’s.
oligopoly
Oligopoly
  • Market Structure in which a few large sellers dominate the industry
  • Products may be distinct like the car industry or standardized like the steel industry
  • When one firm changes prices, enhances product, etc the other firms usually follow or they run the risk of losing customers
monopoly
Monopoly
  • Market structure with a single seller of a particular product
  • Few Pure Monopolies today…very rare
types of monopolies
Types of Monopolies
  • Natural Monopoly: market situation where the costs of production are minimized by having a single firm produce the product
    • IE: Public utilities
  • Geographic Monopoly: market structure based on the absence of other sellers in a particular geographic area
    • IE: Only 1 gas station in a small town
types of monopolies1
Types of Monopolies
  • Technological Monopoly: based on a firm’s ownership or control of a production method, process, or other scientific advance
    • IE: item with a patent
  • Government Monopoly: monopoly owned and operated by the government
    • IE: oversee water use, weapon-grade uranium for military
market failure
Market Failure
  • Condition that causes a competitive market to fail
5 reasons for failure
5 Reasons for Failure:
  • Inadequate Competition
  • Inadequate Information – if the knowledge is important to buyers and sellers but is difficult to obtain
  • Resource Immobility – factors of production do not move to markets where returns are the highest
  • Public Goods – products that are collectively consumed by everyone
  • Externalities – unintended side effect that either benefits or harms a third party not involved.
externalities
Externalities
  • Negative: harm, cost, or inconvenience suffered by a third party because of actions by others
    • IE: Noise from an airport, pollution
  • Positive: a benefit someone receives who was not involved in the activity that generated the benefit.
    • IE: Airport expansion provides more business for local restaurants

Doesn’t matter if they are positive or negative: they are considered market failures, because their costs and benefits are not reflected in the market prices that buyers and sellers pay.

the role of government
The Role of Government
  • The government exercises its power to maintain competition within markets
  • Two ways that government can maintain competitive markets:
    • Prohibiting market structures that are not competitive
    • Regulating markets where full competition is not possible
antitrust legislation
Antitrust Legislation
  • Trust: illegal combination of corporations or companies organized to hinder competition
  • Price Discrimination: the practice of selling the same product to different consumers at different prices
  • Cease and Desist Order: ruling requiring a company to stop an unfair business practice that reduces or limits competition
anti monopoly legislation
Anti-Monopoly Legislation
  • Sherman Antitrust Act 1890 – Outlawed all contracts to stop the growth of trusts and monopolies
  • Clayton Antitrust Act 1914 – Strengthened the Sherman Act by outlawing price discrimination
  • Federal Trade Commission Act 1914 – Established the Federal Trade Commission to regulate unfair methods of competition in interstate commerce.
  • Robinson-Patman Act 1936 – Made it where everyone got the same rebates and discounts
what two market failures does the government have the ability to correct

Q:

Inadequate Information

and Public Goods

What two market failures does the government have the ability to correct?

A:

improve economic efficiency
Improve Economic Efficiency
  • Promote Transparency – information and actions are not hidden and are easily available for review
    • Public Disclosure: requirement that businesses reveal certain information to the public
  • Provide Public Goods
