This teaching powerpoint covers Positive and Negative Externalities

A positive externality is an external benefit, while a negative externality is an external cost. So, positive externalities are situations where the actions of one person or firm benefit others, while negative externalities are situations where the actions of one person or firm harm others. For example, building a new school would be an example of a positive externality, because it benefits the whole community by improving education. On the other hand, building a landfill would be an example of a negative externality, because it harms the community by causing pollution and lowering property values.
