1 Market Structures

2 Chapter 7: Market Structures
KEY CONCEPT A market structure is an economic model that helps economists examine the nature and degree of competition among businesses in the same industry. WHY THE CONCEPT MATTERS The level of competition in a market has a major impact on the prices of products. The more sellers compete for your dollars, the more competitive prices will be.

3 The Characteristics of Perfect Competition
What Is Perfect Competition? The Characteristics of Perfect Competition KEY CONCEPTS Economists classify markets based on how competitive they are Market structure—economic model of competition within an industry Perfect competition—ideal model of a market economy economists assess how competitiveness of market by where it falls short

4 The Characteristics of Perfect Competition
Characteristic 1: Many Buyers and Sellers No one buyer or seller has power to control price in the market Many sellers means buyers can choose a producer with better price Many buyers means sellers can all sell product at market price lack of demand will not cause sellers to lower prices

5 The Characteristics of Perfect Competition
Characteristic 2: Standardized Product Standardized product—one producer’s product is identical to another’s Perfect substitutes include agricultural products, such as wheat, eggs, milk basic commodities, such as notebook paper, gold Price is only basis for consumer choice

6 The Characteristics of Perfect Competition
Characteristic 3: Freedom to Enter and Exit Markets Producers can enter market when profitable and exit when unprofitable Regulations do not restrict businesses from entering or exiting

7 The Characteristics of Perfect Competition
Characteristic 4: Independent Buyers and Sellers Neither buyers nor sellers join together to influence price Supply and demand set the equilibrium price Independent action ensures that market stays competitive

8 The Characteristics of Perfect Competition
Characteristic 5: Well-informed Buyers and Sellers Buyers can compare prices Sellers know what competitors charge, what buyers willing to pay Price taker—seller that accepts market price set by supply and demand

9 Competition in the Real World
KEY CONCEPTS No perfectly competitive markets; none meet all conditions Imperfect competition—market structures that lack one or more of the conditions Some markets come close, such as some wholesale farm products

10 Competition in the Real World
Example 1: Corn Thousands of growers; decide only how much to produce at market price Many buyers; standardized product; wholesale price easy to determine In reality, several factors can interfere: government subsidies; farmers or buyers sometimes band together

11 Competition in the Real World
Example 2: Beef Many producers; each cut of beef is standard sellers can adjust only their production Competition somewhat imperfect because ranchers may join together to influence price producers may say products differ due to factors such as feed

12 Reviewing Key Concepts
Explain the differences between the terms in each of these pairs: market and market structure perfect competition and imperfect competition

13 Characteristics of a Monopoly
The Impact of Monopoly Characteristics of a Monopoly KEY CONCEPTS Monopoly—market structure with one seller, no substitutes for product Cartel—organization of sellers that agree to set prices, limit output Price maker—business without competitors, can set prices Barrier to entry—obstacle to entering market include government regulations, size, resources, technology

14 Characteristics of a Monopoly
Characteristic 1: Only One Seller Single business controls supply of product without close substitutes De Beers cartel controlled diamond market in 20th century because produced over half of world’s diamond supply bought up diamonds from smaller producers to resell

15 Characteristics of a Monopoly
Characteristic 2: A Restricted, Regulated Market Government regulations allow single firm to control market De Beers worked with South African government restricted access of other producers controlled supply of diamonds

16 Characteristics of a Monopoly
Characteristic 3: Control of Prices Monopolists can control prices because there are no close substitutes During economic downturns, De Beers created artificial shortage by withholding diamonds from market, kept prices higher

17 Types of Monopolies KEY CONCEPTS
Natural monopoly—cost of production lowest with only one producer Government monopoly—government owns and runs or permits only one producer Technological monopoly—one firm owns invention, technology, method Geographic monopoly—no other sellers within a region

18 Types of Monopolies Example 1: Natural Monopoly: A Water Company
In some markets, inefficient to have companies competing Example: public utilities that require complex systems economies of scale—average production cost falls as production grows Government both supports and regulates

19 Types of Monopolies Example 2: Government Monopoly: The Postal Service
Government runs some businesses that provide goods and services private firms cannot or do not want to provide because of low profits Example: Postal Service has sole right to deliver first-class mail New services and technologies now compete private delivery companies, fax, , online bill paying

20 Types of Monopolies Example 3: Technological Monopoly: Polaroid
Patent—legal registration of invention; gives inventor sole rights enables businesses to recover costs of development Monopoly lasts for time limit of patent or until substitute invented Patent let Polaroid keep Kodak out of instant-photography market simpler cameras, digital cameras, quick processing reduced its market

21 Types of Monopolies Example 4: Geographic Monopoly: Professional Sports Sports leagues tie teams to cities, regions; limit number of teams owners can charge high ticket prices, sell team merchandise Physical isolation—no other supplier in area—lets owner control prices Very small market may not support two businesses of same type

22 Profit Maximization by Monopolies
KEY CONCEPTS Monopoly cannot set prices too high faces downward-sloping demand curve raises equilibrium price by producing less than competitive market would Most countries have laws to prevent monopolies

23 Profit Maximization by Monopolies
EXAMPLE: Drug Manufacturer Drug companies maximize profits during patent period afterwards, others market cheaper generic versions Schering-Plough strongly marketed non-drowsy antihistamine Claritin made up to $3 billion per year worldwide with patent after patent ended sales dropped to about $1 billion per year

24 Reviewing Key Concepts
Explain the differences between the terms in each of these pairs: monopoly and cartel natural monopoly and geographic monopoly technological monopoly and government monopoly

25 Characteristics of Monopolistic Competition
Other Market Structures Characteristics of Monopolistic Competition KEY CONCEPTS Most real markets fall between perfect competition and monopoly Monopolistic competition—many sellers offer similar products one of most common market structures product differentiation—sellers try to distinguish their products from similar ones nonprice competition—use factors other than price to attract customers

26 Characteristics of Monopolistic Competition
Characteristic 1: Many Sellers and Many Buyers Many sellers and many buyers fewer sellers than perfect competition but enough for true competition Each seller chooses product to make, amount to make, price to charge examples include T-shirts, batteries, hamburger restaurants

27 Characteristics of Monopolistic Competition
Characteristic 2: Similar but Differentiated Products Consumer loyalty gained with unique product or apparent difference Sellers use market research to decide how to differentiate product Chains use sophisticated techniques—learn consumer lifestyles, tastes focus groups—moderated discussions with small groups of consumers survey large numbers of consumers

28 Characteristics of Monopolistic Competition
Characteristic 3: Limited Control of Prices Differentiation gives producers limited control of prices low price distinguishes some products name brands or better quality priced higher Consumers pay extra if they perceive important enough difference will switch to substitute if price goes too high

29 Characteristics of Monopolistic Competition
Characteristic 4: Freedom to Enter or Exit Market No great barriers to entry in monopolistically competitive markets when firms earn profit, other firms enter and increase competition competition can be difficult for small businesses against large ones Some firms start to take losses signal that it is time to exit the market

30 Characteristics of an Oligopoly
KEY CONCEPTS Oligopoly—market structure with only a few sellers offering similar product Less competitive than monopolistic competition each firm has large market share—percent of total sales in the market Few firms due to high start-up costs—expenses of entering market

31 Characteristics of an Oligopoly
Characteristic 1: Few Sellers and Many Buyers A few firms dominate market industry is oligopoly if four firms control 40 percent of market About half of manufacturing industries in United States are oligopolies include breakfast cereals, soft drinks, movies, industrial products

32 Characteristics of an Oligopoly
Characteristic 2: Standardized or Differentiated Products Many industrial products standardized such as flat glass, aluminum firms differentiate by brand name, service, location Many consumer goods are differentiated use marketing strategies, such as focus groups, surveys create brand-name products that can be marketed widely

33 Characteristics of an Oligopoly
Characteristic 3: More Control of Prices Each firm’s decisions about supply and price affect entire market If one firm lowers prices, others probably will too no firm gains market share from price drop; all risk losing profits If one raises prices, others may not in order to gain market share Anticipate competitors’ response to price, output, marketing changes

34 Characteristics of an Oligopoly
Characteristic 4: Little Freedom to Enter or Exit Market High start-up costs—such as factories, warehouses—make entry hard new firm may sell on small scale; hard to compete with established ones Established firms have resources, patents, economies of scale High investment by firms in oligopoly make exit difficult operations too vast, complex to sell and reinvest easily

35 Comparing Market Structures
KEY CONCEPTS Each market structure has benefits, problems each creates different balance of power between producers and consumers Consumer has most influence, little choice in perfect competition Consumer has some influence, most choice in monopolistic competition Consumer has limited influence, some choice in oligopolies Producers have the most control in a monopoly

36 Joan Robinson: Challenging Established Ideas
Explaining Real-World Competition In 1933, Robinson published The Economics of Imperfect Competition Described oligopoly, monopsony (market with many sellers, one buyer) Her theory reflected modern market economies in which firms compete through product differentiation and advertising many industries are controlled by oligopolies

37 Reviewing Key Concepts
Explain the relationship between the terms in each of these pairs: product differentiation and nonprice competition focus group and market share oligopoly and start-up costs

38 Promoting Competition
Regulation and Deregulation Today Promoting Competition KEY CONCEPTS Government regulation—rules or laws that control business behavior promotes competition and protects consumers Antitrust legislation—define monopolies, allow government to control or break them up Trust—group of firms combined to reduce competition Merger—joining of firms or purchase of one firm by another

39 Promoting Competition
Origins of Antitrust Legislation Late 1800s, trusts dominated oil, steel, railroad industries 1890 Sherman Antitrust Act enabled government to control monopolies regulate practices that might reduce competition Standard Oil Company had 90 percent of industry; set output, prices forced to give up control of 33 companies

40 Promoting Competition
Antitrust Legislation Today Federal Trade Commission, Justice Department enforce antitrust legislation tend to support mergers that benefit consumers tend to block mergers that concentrate market in hands of few firms To evaluate potential merger, look at how market is defined market share before and after merger; if competitors get eliminated

41 Ensuring a Level Playing Field
KEY CONCEPTS Government ensures business practices do not reduce competition with less competition, prices go up, supply goes down In United States, laws prohibit most of these practices

42 Ensuring a Level Playing Field
Prohibiting Unfair Business Practices Price fixing—competing businesses collaborate to set prices alternatively, they might agree to restrict output to drive up prices Market allocation—businesses divide up market, control own territory Predatory pricing—set prices below cost to drive out small producers used by cartels or large producers

43 Protecting Consumers KEY CONCEPTS
Cease and desist order—requires firm to stop unfair business practice issued when business behavior is unfair to competitors or consumers Public disclosure—requires businesses to reveal product information enables consumers to make informed buying decisions

44 Protecting Consumers Consumer Protection Agencies
Government protects consumers by regulating different aspects of business Federal Trade Commission promotes competition, prevents unfair practices Other agencies regulate specific industries, protect consumers

45 Deregulating Industries
KEY CONCEPTS 20th century regulation focused on public service industries Deregulation—reduces or removes government oversight and control Deregulation may lead to fewer consumer protections Usually results in lower prices since markets become more competitive with regulated prices, firms have no incentive to reduce costs

46 Deregulating Industries
Deregulating the Airlines Airline Deregulation Act of 1978 removed control of routes and rates Benefits New carriers entered market: greater efficiency, lower prices More people chose plane travel Problems Quality of service declined; airports became crowded Multiple bankruptcies resulted: layoffs, lower wages, lost pensions

47 Reviewing Key Concepts
Explain the differences between the terms in each of these pairs: trust and merger price fixing and predatory pricing regulation and deregulation

48 Competition in Gadgets and Gizmos
