So here we have to think about different types of goods, right? and these goods are classified based on whether they're rival or non -rival.
00:11
And excludable versus excludable.
00:13
Rival means that can more than one person consume it at a time.
00:16
So for a hamburger, only one person can eat the hamburger, but for a sunset, multiple people can look at the sunset at the same time.
00:23
Excludable means can you be forced, can you be forcibly barred from it, right? you cannot go and take someone's private property.
00:33
You can't force the car dealership to give you a car.
00:36
But if you try to appreciate the sunset, nobody can block you from appreciating the sunset.
00:42
If something is rival and excludable, we call it private.
00:46
That is it's totally private to you.
00:48
If it is excludable but rival, we call it club.
00:51
Think of netflix, right? many people can watch the same netflix show at once, but netflix controls the gate about who gets in.
00:58
If it's not excludable, but rival, we call it a commons good.
01:04
Think of a fishery, right? a fishery says that, you know, if one person takes the fish out of the ocean, the other person can't, but everyone can get on the ocean.
01:13
There's no way to block people from fishing.
01:15
And then if it is both non -rival and non -excutable, like our sunset, it's public, right? so we have a number of goods here, right? a toll roads.
01:30
These are a club good, right? the toll road is excludable, right? the toll prevents people from getting on and off, so the toll operating company can block you.
01:44
And at the same time, it's non -rival.
01:46
Many, many people can use the club good at the same time, right? thousands and thousands of people can get on the toll road at the same time.
01:53
So this is a club good, which makes it non -rival but excludable, right? for b, we have a fishery, right? and the fishery, i actually used an example of a commons good.
02:08
The fishery is the classic economic example of a commons good where it is rival, because if you take the fish out of the sea, i cannot also take the fish out of the sea, but it's not excludable.
02:18
Anyone with a boat can go on to the ocean and sort of engage in fishing.
02:26
Absent law, this is maybe the clarification.
02:30
Increasingly, governments around the world are turning this into a private good, right? where they do block people from fishing, right? so if the fish are rival and the government controls who is fishing, then it becomes a sort of the fishery becomes a private good, but the classic fishery where anyone who owns a boat can go fish is a commons good.
02:50
C, ice cream, ice cream is private, right? and that's very simple.
02:55
It is rival...
