Hi, everyone.
00:01
Today we will be solving problem five from chapter 11, which asks us about public goods.
00:07
So to solve this problem, we first need to define what a public good is.
00:12
And it is by definition a good that is not excludable and that is not rival in consumption.
00:18
And we want to focus on the first aspect.
00:20
So the fact that public goods are not excludable.
00:23
What happens is because public goods are not excludable, anyone can be, no one can be prevented from using.
00:30
The good, anyone has access to it.
00:33
And because of this, it creates a free rider problem where essentially some people in the economy are paying for the good, but other people are not paying for the good and are still able to enjoy and use the good.
00:46
For example, if we take the case of fireworks, which are a public good, and if someone in a small town, this is an example from the textbook, if someone from a small town wants to put on some fireworks and they get all their supplies together and they're already, they might end up not wanting to put on the fireworks because they'll soon realize that not everyone is going to buy a ticket to their fireworks show because people in the town will realize that they can just see the fireworks without having to pay for it...
