Market activities provide many benefits to society. However, in some instances, there are unintended side effects from otherwise beneficial market activity. Those side effects are called externalities. Because they are outside of the market, these external costs and benefits are an example of how a market did not work.
An externality can be positive or negative. One example of a positive externality is when your neighbor paints and makes other improvements to his or her house. This increases the value of your house as well.
•In what ways is this an example of a positive externality?
•How could this be an example of a negative externality?
