Answer to Question 1

The purpose of a tax on externalities is to force decision makers to consider real costs that they otherwise would ignore. In the case of pollution, for example, the distortion caused by a tax is desirable. Instead of causing an excess burden, it results in an efficiency gain.

Answer to Question 2

For a good with network externalities, the value of the good to any particular consumer increases as more customers begin to use it. For example, the value to you of being on Facebook is higher the more people who use Facebook. Therefore by acquiring a large customer base, a particular firm may acquire market power.
