Market Structures

1. Market Structures

2. Market Structures Market structure refers to how the market is organized, based mainly on the degree of competition among producers. There are four basic market structure.

3. Market Structures Characteristics of market structure: • Number of producers- helps determine the level of competition • Similarity of products-the degree to which products in the market are similar. The more similar the products are, the greater the competition among producers

4. Market Structures • Ease of entry & exit- how easy is it to enter & exit. Markets that are easy to enter & exit , with few restrictions, have more producers and are more competitive. • Control over price-The ability to influence prices--usually by (control over supply/output) increasing or decreasing the supply of goods--is known as market power.

5. Market Structures Wireless cell phone provider “Cell phone jail” • Offer customers fewer choices • Require binding contracts Clothing companies • Give shoppers many choices • No strings attached

6. Market Structures • Prior to the mid 1990 Tim Horton’s operated with market power in Canada.

7. Market Structures • Perfect Competition is an ideal; there are few market that are perfectly competitive • Characteristics of Perfect Competition: • Many Producers- no individual seller can influence price • Identical Products a product that is exactly the same is called a commodity e.g. grain, cotton, milk & sugar • Easy entry and exit to market- Large number of buyers and sellers • No control over price -–Producers are price takers – have to accept the market price for their product • Easy access to information about products and prices • Transaction cost-the cost of shopping around

8. Market Structures • Example of perfect competition: • Market for milk • 65,000 dairy farmers in US • All offer the same basic commodity • No farmer has market power because of the number of producers • Ease of entry- Anyone can enter the market assuming he or she has the resources

9. Market Structures • Perfect competition exist mainly among agriculture products. • Advantages of Perfect Competition: • Firms operate at maximum efficiency • Consumers benefit- easy access to information about product & price

10. Imperfect Markets • Most markets are NOT perfectly competitive • These market do not allocate goods and services in the most efficient way

11. Market Structures What is a Monopoly? single suppler • Economist call this imperfect competition • The most extreme version of imperfect competition is monopoly

12. Market Structures • Monopoly share four main characteristics: • One Producer -consumer choice limited • Unique producer- no competition/close subsitutes • High barriers to entry • Firm controls price OR output/supply- great market power- price setters rather than price takers.

13. Market Structures • Monopoly: • Pure monopoly – IS RARE! • May survive for a time , but will often break down because of competition or government regulation. • Most feared monopoly was Standard Oil. • Bankrupt its competitors; controlled about 90 percent of U. S. oil sales. • Broke up in 1911 into smaller competing companies.

14. Microsoft • Was the largest provider of computer operating systems • Attempted to drive Netscape out of business by including a free web browser with Windows • Was accused of monopoly/unfair competition • Microsoft settled its case by changing the way it dealt with other software fiirms.

15. Market Structures Three types of legal monopolies: • Resource monopoly – where firm controls key natural resources An example of a resource monopoly is De Beers (South Africa), a diamond mining company. De Beers owns the mines where diamond are found. By controlling this resource, De Beers is able to gain monopoly powers. • Government-created monopolies- Right to grants a single firm or individual the exclusive right to provide a good or service. Pharmaceutical, National Park Service, Public Parking • Natural Monopoly – high fixed costs – gas, electricity, water, telecommunications, rail

16. Market Structures • Advantages and disadvantages of monopoly: • Advantages: • May be appropriate if natural monopoly • Encourages R&D and innovation • Development of some products not likely without some guarantee of monopoly in production • Economies of scale can be gained – the more you produce the cheaper;consumer may benefit

17. Market Structures • Disadvantages: • Higher prices • Limited supply/less choice • Potential for inefficiency – –Complacency over controls on costs

18. Market Structures • Oligopoly is similar to monopoly • It is another form of imperfect competition • Oligopolies are quite common in the real economy • Examples include the airline industry, car companies, or soft drink companies

19. Market Structures Oligopoly • Industry dominated by small number of large firms, however, many firms may make up the industry • High barriers to entry • Similar products could be differentiated - e.g. Coke to Pepsi • Some control over prices

20. Market Structures • Identifying an Oligopoly (p.128 7.4): • Concentration ratio – the proportion of market share accounted for by the four largest firms.

21. Market StructuresWhen an Oligopoly Acts like a Monopoly • Price leadership-Dominating firm may try to control the price through price leadership. • Potential for collusion- when producers get together and make agreements on production levels and pricing • Collusion is illegal because it unfairly limitscompetition • Cartel formation-is an organization of producers established to set production and price level for a product. They are illegal in the U S, but sometime operate on a global scale, most often in commodities. • OPEC is the best known cartel. OPEC consist on a dozen countries that agree to set quotas on oil production and exports. • High degree of interdependence between firms

22. Market Structures Barnes & Noble sell a majority of books publisher, ClearChannel and Viacom own a major portion of radio stations in the U S Five companies own almost all of the channels on your TV set.

23. Market Structures Monopolistic competition has all the condition of perfect competition except for identical products. • Examples – shoes, designer clothing, cosmetics, restaurants, gas stations, service industries such as banks, auto repair shops, supermarkets.etc

24. Market Structures • Monopolistic Competition 1 Many producers or sellers 2 Products differentiated- real or perceived very close substitutes & competing brands are: • Distinct enough to appear unique customers may develop brand loyalty • Loyalty give the favored company market power the company may have a tiny “monopoly” can charge more for its brand. • The competitive aspect is that if sellers raise or lower prices, customer will ignore minor differences and changebrands. 3 Relatively few barriers to entry and exit 4 Firm has some control over price

25. Market Structures Increasing Market share Through Non-price Competition Using price differiation and advertising to attract customers Nonprice focus on four factors: • Physical Characteristic- running shoes • Service- Wholefoods vs Kroger's • Location- • Status and image- Designer jeans vs.. jeans from K-Mart

26. Market Failures: Market Failures Definition: • Where the market structures do not allocate goods and services in the most efficient way.

27. Market Failures • Market Failures occurs where: • Knowledge is not perfect - producers unaware of opportunities, decisions often based on past decisions rather than future knowledge • Goods are differentiated- designer labeling… they cost 3 x more but is the quality 3 X more? • Resource immobility- land,labor, capital • Market Power- e.g. monopoly, collusion • Goods/Services would or could not be provided in sufficient quantity by the market • Existence of external costs and benefits • Inequality exists

28. Market Failures: What are Externalities? • Externalities is spillover effects of production or consumption, some positive and others negative. • An example of a positive externality is a technology spillover- when technical knowledge spreads to other companies thus causing further innovation.

29. Positive Externality • Immunization provides a positive externality. They protect the community---not just the recipients.

30. Market Failures: Negative Externality • Factory pollution is a negative externality. It imposes a cost on people other than the producer and consumer (cost may be monetary, or an undesired effect).

31. Market Failures: How Externalities Reflect Inefficiency • Although positive and negative externalities have very different effect, they are both examples of inefficiency and market Failures. • Why?-because they fail to factor all cost of production and all benefits toconsumers into the model of supply and demand.

32. Market Failures: • External Costs • Decision makers do not take into account the cost imposed on society and others as a result of their decision • e.g. pollution, traffic congestion, environmental degradation, depletion of the ozone layer, misuse of alcohol, tobacco, anti-social behavior, drug abuse, poor housing

33. Market Failures • External benefits� • by products of production and decision making that raise the welfare of a third party • e.g. education and training, health education and preventative medicine

34. Market Failures • Goods and services that generate negative externalities tend to be overproduced. • Goods an services that generate positive externalities tend to be under produced.

35. Market Failures: Public Goods • Goods and services that are not provided bythe market system because of the difficulty getting people who use them to to pay for there use. • Available to everyone (non excludable) • Consumption by one person does not prevent another from consuming (non-rival in consumption) • Free-rider problems- anyone who passes under a streetlight can use it.

36. Market Failures: Private Good • Available only to purchasers (excludable) • Consumption by one person prevents another from consuming (rival in consumption)

37. Assessment Question Which of these is the bestexample of an externality? A. You decide to stop snacking between meals. B. You enjoy looking at your neighbor’s garden. C. Your shoe store stops selling your favorite style. D. Your new bicycle goes faster than you expected.
