DIFFERENT TYPES OF
MARKET STRUCTURES
        What Are Markets?
A market is where buyers and sellers:
 –meet to exchange goods and services.
 –are affected by some level of competition.



    The market may be in one specific place
                        or
        It does not exist physically at all
             (IT IS JUST A THEORY!!)

                    SWS 2006                   2
        What Are Markets?
 Markets are classified by 4 structures

    1. Pure (perfect) Competition

    2. Monopolistic Competition

    3. Oligopoly

    4. Monopoly
                     SWS 2006              3
  1. Perfect Competition
        BEFORE WE BEGIN!!


    This is a theoretical situation.
NO TRUE Perfectly Competitive Market
                 exists.

     IT IS ONLY A THEORY!

               SWS 2006                4
The 5 conditions of perfect competition
1)   LARGE number of SMALL firms.
     No single buyer or seller can influence the price.

2)   Buyers and sellers deal in identical products. No product
     differences. (EXAMPLES: Salt, Flour, Commodity, Corn)

3)   Unlimited Competition: so many firms, that suppliers lose
     the ability to set their own price.

4)   No Barriers to Entry. Sellers are free to enter the market,
     conduct business and free to leave the market. (Low
     cost to enter)
5)   Each firm is a PRICE-TAKER (more on this later)
 CONSUMERS HAVE THE LARGEST SELECTION OF BUYERS TO BUY GOODS
                           SWS MORE APPEALING THAN ANOTHER.

The 5 conditions of perfect competition
4)    No Barriers to entry. Sellers are free to enter the market,
      conduct business and free to leave the market.

        Perfect competition is the opposite of monopoly.
     Here, any firm can get into the market at very little cost.

 Suppose there was a market for dandelions.
  Growing dandelions requires little start-up cost.
 All you need are dandelion seeds, soil, water,
  and some sunlight.
 There is no difference between one dandelion
  and another, so the market has a similar
  product. The agricultural market is the best example
                     of a perfectly competitive market.
                                SWS 2006                        6
             Perfect Competition

 Each individual firm is too small to influence
  prices.
 Price becomes fixed to everyone in the industry.
 EXAMPLE: the price of a bushel of wheat is set
  only by the interaction of supply and demand.
   Generally speaking, wheat is the
  same per bushel in North Georgia
          as it is in Florida.




                          SWS 2006                 7
              Perfect Competition
 Firms in a perfectly competitive market are
 price takers. (they take the price they are given, they
 can’t change the price)

 Since they have no control over their own
                    NO MARKET POWER
 prices, they have _______________________.
        MARKET POWER = “the ability to set one’s OWN prices”



 In other words, no one will buy an overpriced
  dandelion. Why should they?
 A 4-cent dandelion is the same as the 3-cent one,
  so there is no reason to spend that extra penny.
                              SWS 2006                         8
        Monopolistic Competition
 The 5 conditions of Monopolistic Competition
1)   LARGE number of large companies (but fewer than perfect
     competition).
     Sellers can influence the price through creating a product identity
     (more on this later)

2)   Products are NOT exactly identical, BUT VERY SIMILAR,
     so companies use PRODUCT DIFFERENTIATION
3)   Heavy Competition: Firms must remain aware of their
     competitor’s actions, but they each have some ability to
     control their own prices.

4)   Low Barriers to Entry: harder to get started because of the
     amount of competition.
5)   Monopolistic competition takes its name and its structure
     from elements of monopoly and perfect competition. 9
                            SWS 2006
    Monopolistic Competitive Market
STUDY TIP:
 The key idea to understanding monopolistic competition is that
 firms sell products that are similar, but not exactly alike.

    EXAMPLE: Hand Soap

   Essentially, all hand soaps are the same. Yet firms
    can create a brand identity that separates their
    hand soap from their competitor’s.
   This brand identity can be formed through
    packaging, product support, and especially
    advertising.
   If effective, consumers will positively identify a
    certain brand and purchase it even if hand soap
    costs more.               SWS 2006                     10
Conditions of Monopolistic Competition
  The point is that firms in Monopolistic Competition must
  use Product Differentiation & Non-price Competition to
  sell their products.

 Product Differentiation:
 The real or imagined differences
  between competing products in the
  same industry.
 Differences may be real or imagined.

 Differentiation may be color, packaging, store
  location, store design, store decorations,
  delivery, service….. anything to make it stand
  out!                  SWS 2006                        11
Conditions of Monopolistic Competition
  The point is that firms in Monopolistic Competition must
  use Product Differentiation & Non-price Competition to
  sell their products.

 Non-Price Competition:
 Non-Price Competition involves the advertising of a
   product's appearance, quality, or design, rather than its
   price.
 Advertising to help the consumer believe that this product
   is different and worth more money.

                         Notice these
                      commercials never
                              VS
                        mention price.

                             SWS 2006                     12
Examples of Monopolistic Competition

    Auto, Steel, Gas, Fast Food, Airlines.




                     SWS 2006                13
            MERGERS OF LARGE COMPANIES
 Sometimes companies fall victim to market failure. However,
  not all businesses close their doors and empty their factories
  and stores.
 Many get “swallowed up” by another company. This “take-
  over” or acquisition of a company is known as a merger.

There are THREE types of mergers: HORIZONTAL, VERTICAL, and
CONGLOMERATE.
 1.) HORIZONTAL: involve firms in the SAME market, such as between two oil
 companies.
                      Reason: Diversification


 2.) VERTICAL: involve one firm buying a resource provider.
  EXAMPLE: steel company buys an automaker

 3.) CONGLOMERATE: a company buys a business in a
      UNRELATED industry.
                                    SWS 2006                            14
           What is an Oligopoly?
   A market in which a two-three large sellers control
  most of the production of a good or service and they
            work together on setting prices.
        Conditions of an Oligopoly
1) Very few Sellers that control the entire market.
2) Products may be differentiated or identical (but
   they are usually standardized)
3) Medium barriers to entry: Difficult to Enter the
   market because the competitors work together
   to control all the resources & prices.
4) The actions of one affects all the producers.
5) Collusion = an agreement to act together or
   behave in a cooperative manner.
                         SWS 2006                        15
              What is an Oligopoly?
     A market in which a two-three large sellers control
    most of the production of a good or service and they
              work together on setting prices.

             Conditions of Oligopoly
5) Collusion = an agreement to act together or
   behave in a cooperative manner.
    Collusion Agreements: usually illegal, among
   producers to fix prices, limit output, or divide markets.
   (hard to prove that a group of companies is doing this)
    It is also called Price Fixing: setting the same
      prices across the industry.
           THIS IS IN VIOLATION OF ANTI-TRUST LAWS. WHY?
         Basically, the companies are acting a one large monopoly.

                                SWS 2006                             16
         Price Behavior in Oligopoly
 Now, sometimes businesses do not agree with each other about the price,
                 and if that happens, a WAR will result.

Price Wars: Series of price cuts that competitors must
follow or lose business.
 it is a fierce price competition between sellers, sometimes
   the price is lower than the cost of production.
    Why is that bad???




 Oligopolists would like to be Independent Price setters:
   a firm sets prices based on demand, cost of input
     and other factors (not based on other companies prices).
                                SWS 2006                             17
2 Types of Price Behavior in an Oligopoly

 Price Leader: independent pricing decisions made by
   a dominate firm on a regular basis that results in
   generally uniform industry-wide prices.
   ADVANTAGE: you are the company leading the price.


 Independent Pricing: policy by a competitor that
   ignores other producer’s prices.

   DISADVANTAGE: other firms shut you down by
     agreeing to set lower prices than yours.
                         SWS 2006                      18
        Conditions of Monopoly
 Exact Opposite of Pure Competition.
   A price maker. (set their own price, without regard to
     supply and demand)


 There is a single seller

 No close substitute goods are available

 High Barriers to Entry: Other sellers
 cannot enter the Market.

                          SWS 2006                           19
                   Types of Monopolies
                4 Distinct Types of Monopolies:
1)   Natural Monopoly: Where costs are minimized by
     having a single producer of the product.
     Gas, water, electricity: government creates Natural
      Monopolies by Franchising some utilities.
           Franchise - the right to produce or do business in a certain
            area without competition.
           Government franchises come with government regulation.
            Georgia PSC (Public Service Commission)

               WHY WOULD GOVERNMENT DO THIS???

Economies of Scale: As natural monopolies grow larger, this reduces its
    production costs (economies of scale).
     Because normally companies become more efficient as
      the firm becomes larger.
           Example: It is cheaper for the Tennessee Valley Authority
            (TVA) to provide power in Georgia than two or three
            companies.
                                 SWS 2006                            20
               Types of Monopolies

2)   Geographic Monopoly: The only business in
     a location due to size of market.
      Decreasing in the U.S. because of mobility.


                                      EXAMPLE: Only
                                       person selling
                                        water in the
                                          desert.

                   Types of Monopolies

3)   Technological Monopoly: Firm has
     discovered a new process or product.
         Constitution gave government the right to grant
           technological monopolies.
        Patent: 17 years exclusive rights to a developed
         technology.
        Copyright: (Artists and writers) Life plus 50 years.

              Types of Monopolies

4)   Government Monopoly: Retained by the
     government.
      Liquor sales in some counties, uranium
       production, water, etc.

3 Conditions of Efficient & Successful
               Markets
Markets work best when four conditions are met:
  1) Adequate competition must exist in all
     markets.
  2) Buyers and sellers are reasonably well-
     informed about conditions and
     opportunities.
  3) Resources must be free to move from one
     industry to another.

 Market Failure occurs when any of the 3
       conditions alter significantly.
                     SWS 2006                24
       Types & Causes for Market Failure
1)     Inadequate Competition: Dangers to monopolies
          Monopolies may waste and misallocate scarce
           resources because there is no competition.
2) Inadequate Information: A free enterprise economy
     requires information.
          It is difficult to employ resources for the fullest benefit of
           society without adequate information.
3) Resource Immobility: The efficient allocation or resources
     require that land, labor, capital and entrepreneurs be free to move
     to markets where returns are the highest
4) Externalities / Side Effects: A side effect that benefits or harms
     a third party that was not directly involved in the activity.
           Negative Externality: People are harmed or inconvenienced
            by an economic decision.
                                    SWS 2006                                25
         The Role of Government

Government has the power to maintain competition,
 regulate monopolies, or to run government-owned
 monopolies.
  Since the late 1800s the US have passed laws to
   restrict and regulate monopolies and trusts.

     Trust: a legally formed combination of
      companies.




                        SWS 2006                  26
         The Role of Government

               Antitrust Legislation
 Interstate Commerce Act: Passed by Congress
   in 1887. It was aimed at the railroads.
   Charges of unfair pricing prompted Congress
   to act.

1887                                     PRESENT




                     SWS 2006               27
          The Role of Government

1890 - Sherman Antitrust Act - law against
  monopolies that hindered competition or made
  competition impossible because of the “restraint
  of trade” that is created by a monopoly.


1887                                        PRESENT




                       SWS 2006               28
           The Role of Government

 1914 - Clayton Antitrust Act - outlawed price
  discrimination - charging different customers different
  prices for the same product. Further defined Sherman.
  (preferred pricing)



1887                                              PRESENT




                          SWS 2006                   29
                 The Role of Government

 1914 - Federal Trade Commission Act - passed
       to enforce the Clayton Antitrust Act. It gave the
       authority to issue Cease and Desist order.
       Cease and Desist Order: FTC ruling requiring a company to stop an
       unfair business practice that reduces or limits competition.



1887                                                                       PRESENT
