The concept of public good plays a crucial role in understanding economics, governance, and social responsibility. It refers to resources or services that are made available to all members of a society, regardless of their individual contributions. This article will explore the definition, characteristics, and significance of public goods.
Defining Public Good
A public good is defined by two main characteristics: non-excludability and non-rivalry. Non-excludability means that it is not possible to prevent individuals from accessing the good, while non-rivalry indicates that one person’s use of the good does not reduce its availability to others.
- Examples of public goods include clean air, national defense, and public parks.
- These goods are essential for the overall well-being of society.

The Importance of Public Goods
Public goods are vital for several reasons:
- Social Welfare: They contribute to the overall quality of life in a community.
