Public good: A public good is similar to a common resource in terms of being non-excludable, but it is non-rivalrous, meaning one person's use does not diminish its availability for others.
Private good: In contrast to a common resource, a private good is both excludable and rivalrous. It can only be consumed by those who pay for or own it, and consumption by one person prevents others from using it.
Club good: A club good is excludable like a private good, but it is non-rivalrous like a public good. While access may be restricted to certain individuals or groups, consumption by one person does not reduce its availability for others within the group.
