Write down a two to three (2-3) page paper in which you:
1. Find out and discuss three externalities, which can either be positive or negative.
2. Conclude why an externality might exist in the situation that you described, and calculate the solutions to mitigate these particular externalities.
3. Examine the different stakeholders (i.e., government, three (3) affected parties) that are involved in the externality, and find out what their roles are with regard to the externality.
