  • 00:01

    Now, cost curves are always going to look the same, but other elements, like price,

  • 00:07

    revenue, and demand, will differ depending on the market structure that the business

  • 00:12

    operates in.

  • 00:13

    Are there other lots of producers, or only a few?

  • 00:16

    Is my product just like everyone else’s, or is it unique?

  • 00:20

    The characteristics of a market will clue you in as to the type of market structure

  • 00:24

    you're dealing with.

  • 00:26

    Really there is a continuum of market structures.

  • 00:28

    Let's take a look.

  • 00:29

    At one extreme, we have perfect competition.

  • 00:33

    Well, if it's competitive, how many producers are we talking about?

  • 00:37

    A lot.

  • 00:39

    How many is “a lot,” or “a large number”?

  • 00:42

    Economists aren’t really specific about this, but a large number of producers means

  • 00:46

    that there are so many competitors that each one is too small to affect the market.

  • 00:52

    In my mind, I tend to think of maybe 100 or more, so that each competitor has 1% or less

  • 00:57

    of the market.

  • 00:58

    Since nothing you do affects the market, no one really cares what you do, and you are

  • 01:02

    free to make decisions without worrying about how the competition will react.

  • 01:07

    How else can recognize a perfectly competitive market?

  • 01:10

    Besides having a large number of sellers, each of those sellers will be producing exactly

  • 01:15

    the same thing.

  • 01:17

    In perfect competition, the product is identical -- or homogeneous, or non-differentiated -- no

  • 01:23

    matter who produces it.

  • 01:25

    One more characteristic: it’s easy for firms to come and go from the industry; that is,

  • 01:29

    there is free entry and exit.

  • 01:32

    Think about it.

  • 01:33

    This industry has lots of producers.

  • 01:35

    Why?

  • 01:36

    Because it's easy to get in and set up shop.

  • 01:38

    In an industry like this -- lots of producers, all producing exactly that the same thing

  • 01:44

    -- how much market power (where market power is defined as the ability to control the price)

  • 01:50

    does an individual firm have?

  • 01:52

    None.

  • 01:53

    You have no ability to drive the price, because 1) you're so small, and 2) everyone else produces

  • 02:00

    exactly what you do.

  • 02:02

    TIME TO THINK: what would happen if you tried to raise your price?

  • 02:07

    Now let's take a look at the opposite extreme of the market structure spectrum.

  • 02:11

    Instead of a huge number of producers, there's only one producer for the whole market, or

  • 02:17

    a monopoly (the prefix “mono” meaning “one”).

  • 02:20

    Furthermore, the monopolist’s product is unique; there really are no substitutes for

  • 02:25

    this product.

  • 02:26

    Lastly, in a monopolistic industry, entry by other firms it nearly impossible due to

  • 02:32

    the extremely high barriers to entry.

  • 02:34

    We’ll get into this more later, but a barrier to entry could be really high costs, or legal

  • 02:39

    protection like patents or copyrights.

  • 02:42

    Given all of these characteristics -- only one producer, a unique product, and no one

  • 02:46

    else can get into the industry to compete with you -- how much market power (ability

  • 02:50

    to control price) does the monopoly producer have?

  • 02:54

    The monopolist has complete control over the price, within the boundaries of what consumers

  • 02:59

    are willing to pay.

  • 03:00

    Are there other structures?

  • 03:02

    Sure -- in fact, most real-world industries will fall somewhere in the middle ground,

  • 03:06

    not at the theoretical extremes of perfect competition or monopoly.

  • 03:10

    Two of these midrange structures are monopolistic competition and oligopoly.

  • 03:15

    A monopolistically competitive structure is still competitive, so there are still a lot

  • 03:19

    of producers; given there are lots of producers, we can assume that entry into the industry

  • 03:24

    is easy.

  • 03:26

    Unlike perfect competition, however, the products are not exactly the same.

  • 03:31

    Highly similar, yes; highly substitutable, yes; but not identical.

  • 03:37

    Think about, oh, toothbrushes.

  • 03:39

    You go to the store, and there are toothbrushes with square heads, diamond heads, rubber-grip

  • 03:44

    handles, bi-level bristles, toothbrushes that play music, toothbrushes that glow in the

  • 03:48

    dark, even with color indicators that tell you when to buy a new toothbrush.

  • 03:52

    All toothbrushes, all highly similar and highly substitutable, but with slight differences.

  • 03:58

    If I believe, as a consumer, that having a rubber-grip handle helps clean my teeth better,

  • 04:03

    then this differentiation gives the producer a small amount of market power.

  • 04:08

    He/she could raise the price a little bit, and I would still buy that rubber-grip handle

  • 04:13

    toothbrush.

  • 04:14

    If they raise the price too much, though, I'll switch to some other type of toothbrush.

  • 04:19

    An oligopoly?

  • 04:21

    Well the prefix “oli” means “few,” so I'll have a few large producers making

  • 04:26

    up the market, each with a large amount of control, or market power.

  • 04:30

    There are some barriers to entry, so it's hard, but not impossible, to get in.

  • 04:35

    The product in an oligopolistic market can be identical, like the members of OPEC who

  • 04:40

    produce oil, or differentiated, like car manufacturers.

  • 04:44

    Also, the “small number” of producers could be just a handful, like cars, or a couple

  • 04:50

    dozen, like the oil producers.

  • 04:52

    The key is that there are few enough producers that each one has a fairly large chunk of

  • 04:58

    the market; large enough that any individual producer can affect what happens in the market.

  • 05:03

    Because everyone's actions matter, the producers become mutually interdependent; whatever one

  • 05:09

    does affects everyone else.

  • 05:12

    This mutual interdependence actually makes the oligopoly the most complicated type of

  • 05:16

    market structure to operate in.

  • 05:18

    Now that you know something about each market, I have an exercise for you: see if you can

  • 05:23

    come up with real-world examples for each type.

  • 05:26

    What kind of product, or products, would fit the perfectly competitive structure?

  • 05:32

    What about monopolistically competitive?

  • 05:35

    Oligopolistic?

  • 05:36

    What about monopolistic?

  • 05:38

    Have your answers ready, because I'll be asking for your responses in our next class.
