So this question asks us to determine the differences between public and private goods.
00:06
And there are two different characteristics that all public goods have.
00:09
The first is that they are non -exclusionary.
00:14
What this means is that it's impossible to exclude people from enjoying the good and the benefits of the good, even if they don't pay for it.
00:22
The second characteristic is that they are non -rivalrous.
00:29
What this means is that one person's consumption of this good doesn't reduce the utility or the usefulness.
00:35
That others can derive from that same good.
00:38
And so in order for a good to be public good, both these characteristics need to be intact.
00:45
So that answers the first two questions.
00:47
The free rider problem relates specifically to this first idea of non -exclusionary goods...
