What is an intangible public good?

Answer 1

An intangible public good is a service or benefit that is not physically tangible and cannot be easily quantified, yet provides value to society as a whole. Examples include clean air, public safety, and national defense. Unlike tangible goods, intangible public goods are non-excludable and non-rivalrous, meaning that one person's consumption does not diminish availability for others, and it is difficult to prevent anyone from benefiting from them. Their provision often relies on government action or collective efforts, as private markets may underprovide these goods due to their nature.
