What describes excludable goods in economic terms?

Excludable goods are defined as those resources or goods that can be restricted or limited in availability to potential users. This means that the owner of the good has the ability to prevent individuals from using it unless they pay for access or meet certain conditions. This characteristic is crucial in the context of markets and economic transactions, as excludability impacts how goods are priced and allocated.

For instance, a private park that charges an entry fee is an example of an excludable good because access can be restricted to paying customers only. The ability to exclude non-payers reinforces the economic value and marketability of such goods, as it allows the owner to generate revenue from them.

In contrast, other options suggest concepts that do not align with the definition of excludable goods. Goods available to everyone without restriction refer to non-excludable goods, which are accessible to all individuals regardless of payment. Free resources that cannot be owned align more closely with common goods, while goods that increase in value as more people use them describe positive externalities, typically seen in public goods. Hence, the focus on the ability to restrict access is what distinguishes excludable goods in economic terms.
