Title: 7-1: WHAT IS PERFECT COMPETITION?


1
7-1 WHAT IS PERFECT COMPETITION?
2
Competition
  • Economists classify markets based on how
    competitive they are
  • Market structure an economic model of
    competition among businesses in the same industry

3
Perfect Competition
  • Definition ideal model of a market economy
  • Perfect competition is used as a basis to
    determine how competitive a market is

4
5 Characteristics of Perfect Competition
  • 1. Numerous buyers and sellers
  • This ensures that no single buyer or seller has
    the power to control the price in the market

5
5 Characteristics of Perfect Competition
(continued)
  • Buyers have lots of options
  • Sellers are able to sell their products at market
    price

6
  • 2. Standardized product
  • A product that consumers see as identical
    regardless of the producer
  • Example milk, eggs, etc.

7
Characteristics of Perfect Competition (continued)
  • 3. Freedom to enter and exit markets
  • Producers enter the market when it is profitable
    and exit when it is unprofitable

8
Characteristics of Perfect Competition (continued)
  • 4. Independent buyers and sellers
  • This allows supply and demand to set the
    equilibrium price

9
Characteristics of Perfect Competition (continued)
  • 5. Well-informed buyers and sellers
  • Buyers compare prices
  • Sellers know what consumers are willing to pay
    for goods

10
Price Taker
  • When these 5 conditions are met, sellers become
    price takersa business that accepts the market
    price determined by supply and demand

11
Imperfect Competition
  • Market structures that lack one of the conditions
    needed for perfect competition are examples of
    imperfect competition
  • This means there are only a few sellers and/or
    products are not standardized
  • Examples corn and beef markets

12
7-2 THE IMPACT OF MONOPOLY
13
Characteristics of a Monopoly
  • Monopoly a market structure in which only one
    seller sells a product for which there are no
    close substitutes
  • Pure monopolies are rare

14
Characteristics of a Monopoly (continued)
  • A cartel is close to a monopoly
  • Cartel a group of sellers that act together to
    set prices and limit output
  • Example OPEC11 nations hold more than 2/3 of
    the worlds oil reserves

15
Characteristics of a Monopoly (continued)
  • A monopoly is a price makera business that does
    not have to consider competitors when setting the
    price of its product
  • Consumers accept the price of the product

16
Characteristics of a Monopoly (continued)
  • Other firms struggle to enter the market due to a
    barrier to entrysomething that stops the
    business from entering a market

17
3 Characteristics of Monopolies
  • 1. Only One Seller
  • Supply of product has no close substitutes

18
3 Characteristics of Monopolies
  • 2. A Restricted, Regulated Market
  • In some cases, government regulations allow a
    single firm to control a market (think utilities)

19
3 Characteristics of Monopolies
  • 3. Control of Prices
  • Prices are controlled since there are no close
    substitutes

20
Types of Monopolies
  • First, not all monopolies are harmful
  • Natural monopoly occurs when the costs of
    production are lowest with only one producer

21
Types of Monopolies (continued)
  • Example of a natural monopoly public utilities.
    It would be inefficient to have more than one a
    water company competing for customers.
  • A single supplier would be most efficient
    according to economies of scale when the average
    cost of production falls as the producer grows
    larger

22
Types of Monopolies (continued)
  • Government monopoly exists because the
    government wither owns and runs the business or
    authorizes only one producer
  • Example (U.S. Postal Service), DMV

23
Types of Monopolies (continued)
  • Technological monopoly occurs when a firm
    controls a manufacturing method, an invention, or
    a type of technology
  • Example a patent, where an inventor has
    exclusive rights to that invention or process for
    a certain number of years

24
Types of Monopolies (continued)
  • Geographic monopoly exists when there are no
    other producers within a certain region
  • Example professional sports teams

25
Businesses like Monopolies or more Market power
  • Cartels
  • Mergers
  • Predatory Pricing price below costs until
    competitors go out of business
  • Require a store to stock all of its products

26
Government Promotes Competition
  • 1890 Sherman Anti-trust Act
  • Outlaws mergers and monopolies that limits trade
    between states
  • Companies broken up under the law
  • 1911 Standard Oil and Trust
  • 1982 ATT

27
Microsoft
  • 1997 accused of using near monopoly to take over
    operating system market
  • 1999 Judge ruled against Microsoft.
  • 2001 deal Microsoft can link Internet Explorer
    to their operating system, but cant force
    computer companies to only provide Microsoft on
    new computers.

28
Government Promotes Competition
  • By preventing mergers
  • AOL and Time Warner OK to merge
  • Libbey and Anchor Hocking not allowed to merge
  • Degregulation
  • Some regulations reduce competition
  • Airlines, banking, trucking
  • More competitors join

29

    to sell his wheat for 2.50 per bushel if the
    market price were 2.00 per bushel? Why?

31
