Chapter 7 Market Structures

1. Chapter 7Market Structures Hello!

2. Market Structure • Market structure refers to the ways that competition occurs, based on the number of firms, the similarity of the products being sold and the ease of entry for new firms or exit for existing firms. • Four Basic Structures *Perfect Competition *Monopoly *Monopolistic *Oligopoly

4. Barriers to Entry • Barriers – factors that make it difficult for new firms to enter a market • Barriers lead to imperfect competition

5. Examples of Barriers • Start-Up Costs – The expenses a new business must pay before it can enter the market • High Start-Up Costs prevent new firms from entering

6. Examples of Barriers • Technology – how much training does it take to enter the market?

7. Examples of Barriers • Government – may require licensing, certification, approval, etc.

8. Perfect Competition • Perfect Competition – a market where a large number of firms are all producing essentially the same product

9. Conditions Perfect Competition • Many buyers and sellers participate • Sellers offer identical products • Products that are the same no matter who makes or sells them are commodities

10. Perfect Competition • Buyers and sellers are well informed about products • Sellers are able to enter and exit the market freely

11. Price and Output • A perfectly competitive market produces the lowest sustainable prices possible • With many firms competing, each firm lowers its prices to the point of just covering their costs

12. Monopoly • Monopoly – Barriers prevent firms from entering a market that has a single supplier

13. Factors that Create a Monopoly • 1. Economies of Scale – average cost of production always drops, never increases • 2. Natural Monopoly – market runs most effectively when one large firm provides all output

14. Factors that Create a Monopoly • Natural Monopolies are usually given special status by the government, but the government is allowed to control their prices • New technologies can destroy a natural monopoly

15. Government Monopolies • Government Monopoly – a monopoly created by the government

16. Typical High School Boy Questions? Wait… what’s a government monopoly?

17. Government Monopolies • Government Monopoly – a monopoly created by the government • There are 3 types of government monopolies, each with a different reason for being formed

18. Three Kinds of Government Monopoly • Technological Monopoly – government issues a patent • Patent – exclusive rights to sell a good or service for a specific period of time

19. Three Kinds of Government Monopoly • Franchises and Licenses • Franchises – government allows company to create an exclusive market for their brand name and products

20. Three Kinds of Government Monopoly • Franchises and Licenses • Licenses – government grants a firm the right to operate a business

21. Three Kinds of Government Monopoly • Industrial Organizations – government allows companies in an industry to restrict the number of firms in the market

22. Output Decisions • Do you emphasize price or output? • Price-Takers – in a competitive market, businesses have no control over their own prices • Price-Setters – in a non-competitive market, business can choose what price to charge

23. Price Discrimination • Do you think monopolies usually charge the same price to all of their customers?

24. Price Discrimination NO!!

25. Price Discrimination • Price Discrimination – dividing consumers into different groups and charging different prices to each group

26. Price Discrimination • Monopolies are not the only companies that do this • Any company with market power, the ability to control prices and output, can use discrimination

27. Price Discrimination • The easiest way to maximize profit for a monopoly is to identify consumers who will not pay full price, and offer them a “discount” • These are called targeted discounts – think of airline fares, manufacturers rebates, student discounts

28. Limits to Price Discrimination • 1. Firm must have some market power • 2. There must be distinct consumer groups • 3. It must be difficult for consumers to resell the product

29. Monopolistic Competition • Monopolistic Competition – many companies compete in an open market, but sell products that are slightly different from one another

30. Example

31. 4 Characteristics of Monopolistic Competition • 1. Many Firms • 2. Few Artificial Barriers to Entry • 3. Slight Control Over Prices • 4. Differentiated Products

32. Other Means of Competition • In a Monopolistic Competition, firms compete in a variety of ways other than prices • Physical Characteristics • Location • Service Level/Quality • Advertising and Image

33. Oligopoly • Oligopoly – a market dominated by a few large, profitable firms • If 4 of the largest firms can claim 70% or more of the market share, it is an oligopoly

34. Example

35. Example

36. Characteristics of Oligopoly • 1. Many Barriers to Entry • 2. Cooperation and Collusion • Price Leadership – market leader raises prices, other firms follow suit (can also cause price war, though)

37. Characteristics of Oligopoly • 1. Many Barriers to Entry • 2. Cooperation and Collusion • Collusion – an agreement among members of an oligopoly to set prices and production levels

38. Characteristics of Oligopoly • 1. Many Barriers to Entry • 2. Cooperation and Collusion • Collusion causes price fixing, where firms agree to sell at the same or similar prices • It’s illegal, by the way

39. Characteristics of Oligopoly • 1. Many Barriers to Entry • 2. Cooperation and Collusion • Cartels – an agreement by producers to coordinate prices and production • Legal in some countries, not here

40. Regulation and Deregulation • What might a firm do to increase its market power? • Form a cartel • Merge with competitors • Predatory Pricing - Temporarily lower prices to put others out of business

41. Regulation and Deregulation • Government has Antitrust Laws in place to prevent such practices • Trust – a business combination similar to a cartel • Began with Sherman Antitrust Act in 1890

42. Fair or Unfair? • Nike is one of the world’s largest and most popular shoe manufacturers • Once Nike introduced clothing, it forced companies that wanted to buy its shoes to buy its clothes as well

43. Fair or Unfair? • Disney, ABC, AOL, and Time-Warner have merged together • They now control the Disney Channel, Cartoon Network, and the WB, which is a basic monopoly on children's programming

44. Regulation and Deregulation • Government can step in and break up monopolies based on the Sherman Antitrust Act • Famous examples: John D. Rockefeller’s Standard Oil (1911), AT&T (1982)

45. Regulation and Deregulation • Government can also block mergers from happening • Merger – when one company joins with another • Government uses research to see whether the merger will help or hurt consumers

46. Regulation and Deregulation • The Republican Party has typically supported deregulation – when the government stops making decisions about what businesses can and cannot do • Government uses regulation and deregulation for the same purpose – to promote competition
