Public vs. Private Goods

  • Each good can be categorized as being either rival or nonrival
  • Each good is also categorized as being either excludable or nonexcludable.
  • Private goods are rival and excludable like pizza.
  • Public goods are nonrival and nonexcludable like national defense.
  • Common resources are rival and nonexcludable like a fish in a lake.
  • Artificially scarce resources are nonrival and excludable like pay-per-view television.
  • Generally, government gets involved in nonrival and nonexcludable goods whereas the free market works best in rival and excludable situations.
