Public goods are defined through their lack of two distinct types of externalities

- rivalry
- excludability

They are NOT defined by exclusion of other externalities e.g.

- being beneficial to society
- being more morally good than morally bad
- being inclusive and/or universally accessible

I’m down with public goods, but I don’t see how these definitions are workable?

I feel like if I exclude nobody, for sure rivalries

Something that’s morally good, depends on time, place, and people’s perspectives within the time and place, witch burning was probably a moral good for a hot minute

can u expand this pls

It’s just what happens when you put humans in the same place or give them the same setup, someone wants to compete with someone else whether the other someone is or not

Put me on a public road, I’m driving faster than you, bigger the road, the more racing we can do

You made a big road? I’m making a bigger road
