Quizplus · Accepted Answer

A public good is nonrival, meaning one person's consumption of it does not diminish the availability for others, and nonexcludable, meaning it is difficult or impossible to prevent someone from using it. A common resource, on the other hand, is rival but nonexcludable. Public goods are typically not purchased individually and provide benefits to society as a whole, rather than just those who decide to buy it.
