A negative externality (also called external cost or external diseconomy) is an economic activity that imposes a negative effect on an unrelated third party. It can arise either during the production or the consumption of a good or service.
When negative externalities are present, it means that the producer does not bear all costs, resulting in excess production. With positive externalities, the buyer does not get all the benefits of the good, resulting in decreased production. An example of a negative externality is a factory that produces widgets but pollutes the environment in the process. The cost of the pollution is not borne by the factory but instead shared by society.
