- [Prof. Alex Tabarrok] 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.
