Definition
A positive externality occurs when a third party benefits from an economic transaction they are not directly involved in. This often leads to benefits that are not reflected in the market price.
Summary
Positive externalities are beneficial effects experienced by third parties who are not directly involved in an economic transaction. These externalities can lead to significant societal benefits, such as improved education, public health, and environmental conservation. Understanding positive externalities helps us recognize the broader impacts of economic activities beyond immediate transactions. For example, when individuals invest in their education, they not only enhance their own skills but also contribute to a more knowledgeable workforce, which benefits society. Governments often play a role in promoting positive externalities through policies and subsidies, ensuring that these societal benefits are realized and sustained over time.
