A public good is a product that one individual can consume without reducing its availability to another individual (non-rivalrous) and from which no one is excluded (non-excludable) (Investopedia
). Examples of public goods include roads and national defence.
This topic uses the concept of public goods and the "free rider problem" to explore why some goods are produced at less than socially optimal levels by markets.
Topic Learning Outcome: Appropriately utilize and interpret results of applying the principles of public goods and commons problems to the analysis of public policy and management problems.
Core Concepts associated with this Topic: Free Rider, Public Good, Tragedy of the Commons
