Question

4.02b homework
provide three examples of public goods in your hometown. explain how each is nonrival and non-excludable.

Explanation:

1. City Public Park: Nonrival means one person's use doesn't reduce others' ability to use it (e.g., multiple people can picnic/walk there at once). Non-excludable means it's impractical to bar people from entering the park without extreme cost.
2. Local Street Lighting: Nonrival: One person benefiting from the light doesn't stop others on the same street from using it. Non-excludable: It's impossible to prevent a pedestrian or driver on the street from accessing the light.
3. Public Emergency Siren System: Nonrival: One person hearing the siren doesn't prevent others in the area from hearing it. Non-excludable: There's no way to block specific people from receiving the siren alert.

Answer:

1. City Public Park: Nonrival - simultaneous use by many is possible; Non-excludable - no practical way to bar entry.
2. Local Street Lighting: Nonrival - light serves multiple users at once; Non-excludable - cannot block access to the light.
3. Public Emergency Siren System: Nonrival - all in range hear it at once; Non-excludable - no way to exclude specific people from the alert.
