In the previous video
-
we covered public goods,
-
which are nonexcludable,
and nonrival.
-
Let's now turn to club goods.
-
Club goods are also nonrival,
-
but unlike public goods,
they are excludable.
-
Let's take Wi-Fi as an example.
-
You might need a password
to connect to a Wi-Fi network.
-
That's what makes it excludable.
-
However, assuming that
there isn't much congestion,
-
there's no cost to allowing
more people onto the network.
-
Up to a point, therefore,
Wi-Fi is non-rival.
-
HBO -- that's another example
of a club good.
-
It's excludable --
you have to pay $15.99 a month
-
or something like that
to get into the HBO club.
-
But more viewers don't add to costs,
-
so HBO is also nonrival.
-
Markets can provide club goods,
-
but at the price
of some inefficiency.
-
Imagine for example
that someone is willing to pay
-
$8 per month
to watch Game of Thrones.
-
The marginal cost of HBO
-
providing that viewer
with Game of Thrones --
-
it's basically zero.
-
The potential viewer
is willing to pay $8,
-
which is more than the cost.
-
Yet they don't get to watch,
-
because the price
of HBO is even higher --
-
$15.99 per month.
-
This is unlike competitive markets
that we covered earlier,
-
where we saw trades get made
-
so long as the value
is greater than the cost.
-
For club goods, there's some
loss of efficiency in exclusion.
-
In excluding this
particular viewer, for example,
-
since the benefit to the viewer
is greater than the cost,
-
yet that trade is not made.
-
Now, the fact that HBO
charters for entry to it's club --
-
that means that HBO, however,
-
has an incentive to figure out
what viewers really want to watch.
-
That's an important benefit.
-
The diversity, creativity
and responsiveness of the market
-
probably outweighs
the loss of efficiency
-
in having the market
produce club goods.
-
As we covered in the last video,
-
public goods
tend to be under-provided,
-
because they cannot
be adequately charged for.
-
One solution to this problem
-
is figuring out how to turn
a public good into a club good.
-
And entrepreneurs
have created excludable goods,
-
like cable tv and satellite radio,
-
that are alternatives
to the public goods
-
of broadcast television and radio.
-
Other entrepreneurs
have even discovered ways
-
to profit from providing public goods
-
even without relying on exclusion.
-
How's that possible?
-
Radio and broadcast television --
they're public goods.
-
They're nonexcludable, and nonrival,
-
and yet they are
provided privately by markets.
-
In this case, the market overcame
the challenge through advertising.
-
Advertising -- it really works
quite well for TV and radio.
-
The marginal costs of providing
someone a radio or TV signal --
-
it's zero.
-
And the price -- it's zero as well.
-
Price equals marginal cost --
that's efficient.
-
Now, you do have to watch the ads,
-
and that's profitable
because they're selling the ad time.
-
Here's another familiar example,
-
maybe you've heard of it -- Google.
-
The search technology
and the database are nonrival.
-
Google could exclude
by adding a subscription cost.
-
But it chooses not to,
-
since it makes more money
by giving the product away for free
-
and selling advertising.
-
Now let's go back to Wi-Fi.
-
It's a very interesting case,
-
because we can see Wi-Fi provided
in almost all possible ways.
-
It's sold by private firms,
like Sprint,
-
who exclude non-payers.
-
It's offered free
to attract customers
-
at places like Starbucks.
-
It's free in other places
if you watch ads.
-
And it's even provided for free
by some local governments.
-
So we see all types
of provision methods for Wi-Fi,
-
and it's not clear
which is the best,
-
or even if there is a best method.
-
Okay, that's it for club goods.
-
Next we'll be looking at
nonexcludable,
-
but rival resources --
-
the common resources.
