An externality is an effect of a decision on a third party not taken into account by the decision maker. One example that comes to mind is a new business opening in an area. The decision of where to place a new Wal-Mart is an important decision for the company. But in the course of making that decision, they will not consider every alternative. For example, some of the other businesses in the area may experience larger sales because Wal-Mart will bring more people to the area. An externality can be positive or negative. A negative externality is negative when the decision is detrimental to those outside the decision. A positive externality occurs when the effect of a decision is beneficial to others outside the decision.

Positive externality, firms are underproducing a good with a social benefit and thus the optimal equilibrium occurs at increased production.
