A private good, as opposed to a public good, is a good that is both excludable and rivalrous. Excludability means that it is possible to prevent people from consuming the good if they do not pay for it. Rivalry means that one person’s consumption of the good reduces the amount available to others. Common examples of private goods include food, clothing, and housing.
What is a Private Good
In economics, a private good is a good that is both rivalrous and excludable. This means that it can only be consumed by one person at a time. For example, a slice of pizza is a private good because it can only be eaten by one person at a time, and once it is eaten, it is gone. In contrast, a public good is non-rivalrous and non-excludable, meaning that it can be consumed by many people at the same time and no one can be prevented from consuming it. For example, clean air is a public good, because everyone can breathe it at the same time and no one can be prevented from doing so.
Here is a table summarizing the key characteristics of private and public goods:
| Characteristic | Private Good | Public Good |
|---|---|---|
| Rivalrous | Yes | No |
