Benefits that accrue to parties other than the firms that produce them are called Positive externalities.
When a benefit multiplies, a positive externality happens. Therefore, externalities happen when a transaction's costs or benefits are shared by parties other than the producer or the consumer. Imagine your town has a plant that manufactures widgets, a product that is useful to buyers everywhere.
Market outcomes that are inefficient are also a result of positive externalities. Positive externality-affected items, however, offer people in society greater value than is recognized by those who produce them. When a benefit accrues to a third person, there is a positive externality. By taxing products and services that result in spillover costs, the government can deter negative externalities. By providing subsidies for products and services that have positive spillover effects, the government can promote positive externalities.
