Public Goods Theory
Public Goods Theory refers to goods that are made available to everyone, regardless of who pays for them. These goods are characterized by two main features: non-excludability, meaning no one can be prevented from using them, and non-rivalry, meaning one person's use doesn't diminish another's ability to use them. Examples include clean air and national defense. Because private companies may struggle to profit from these goods, governments often step in to provide them, ensuring that everyone benefits, regardless of their contribution. This theory highlights the importance of collective responsibility for resources that serve the common good.

Public goods theory focuses on goods that are non-excludable and non-rivalrous, meaning that once they are provided, no one can be excluded from using them, and one person's use does not reduce availability for others. Examples include clean air, national defense, and street lighting. Because people can benefit without paying, there's a tendency for individuals to "free ride," leading to underproduction of these goods. To ensure adequate supply, governments often step in to provide and fund public goods, recognizing their vital role in supporting society as a whole.

Public goods theory refers to goods that are non-excludable and non-rivalrous. This means that once they are provided, no one can be excluded from using them, and one person's use doesn't reduce their availability for others. Classic examples include clean air, national defense, and public parks. Because individuals can't be easily charged for their use, there's little incentive for private companies to produce these goods, often leading to under-provision. Therefore, governments typically step in to provide and manage public goods to ensure that society benefits as a whole.
