GOOD TYPES: We can identify four different types of goods based on two key characteristics -- rival consumption and excludability. Private that are rival in consumption and easily subject to the exclusion of nonpayers. Public goods that are nonrival in consumption and the exclusion of nonpayers is virtually impossible. Near-public goods that are nonrival in consumption and easily subject to the exclusion. Common-property goods that are rival in consumption and not easily subject to the exclusion.
