In public goods, what does non-excludable mean?

• A. People can be easily excluded from using it.
• B. It is non-excludable and rival.
• C. It is excludable and non-rival.
• D. It is non-excludable; people cannot be easily excluded from using it.

Answer: (D)

Non-excludable means you can’t easily prevent people from using the good, even if they don’t pay. Once the good is provided, access isn’t practically restricted to paying users. That’s why public goods like national defense or clean air are available to everyone in the area; it’s not feasible to exclude non-payers. Because access can’t be shut off easily, the burden of paying often falls on others, leading to free-rider problems. The statement that matches this idea is that people cannot be easily excluded from using it. The other descriptions describe situations where exclusion is possible or introduce rivalry, which aren’t part of the non-excludable idea.
