Answer to Question 1

An externality is a cost or benefit of an economic activity that is borne by third parties. A good generating a positive externality is underproduced and underconsumed. A good generating a negative externality is overproduced and overconsumed. The government can correct a positive externality by either producing the good itself or by providing a subsidy equal to the external benefit, and can correct a negative externality by either imposing a tax equal to the external cost or by direct regulation.
