Question

What type of good is the San Francisco Golden Gate Bridge? Distinguish if it is rival or non-rival, and excludable or non-excludable.

Answer 1

It is a public good because every one can use the bridge.

Public good have two main characteristics that is Non-rival and Non excludable.

Non-rival means use by one person does not affect the use of other person. use of bridge by one does not affect the use by other. So it is non-rival.

Non-excludable means no one could be prevented to use the good. Entry to bridge is free so no one is denied the entry, it is non-excludable.

So bridge have both the characteristics of public good. So it is a public good.
