Public goods are commodities or services that are made available to all members of a society. They are typically characterized by two main features: non-excludability and non-rivalrous consumption. Non-excludability means that it is not possible to prevent anyone from accessing the good once it has been provided, while non-rivalrous consumption indicates that one person's use of the good does not reduce its availability to others. Classic examples of public goods include national defense, public parks, and street lighting. In economic terms, public goods are important because they often require government intervention or collective action to ensure they are provided, as private markets may underproduce them due to the free-rider problem, where individuals may benefit from the good without contributing to its cost. Understanding the principles of public goods is essential for technical professionals involved in public policy, economics, and resource management, as these goods play a crucial role in welfare and economic efficiency.
