Distinguish between positive and negative externalities in an economy

Draw a standard supply and demand diagram for televisions, and indicate the equilibrium price and output. a. Assuming that the production of televisions generates external costs, illustrate the effect of the producers being forced to pay a tax equal to the external costs generated, and indicate the equilibrium output. b. If instead of generating external costs, television production generates external benefits, illustrate the effect of the producers being given a subsidy equal to the external benefits generated, and indicate the equilibrium output.

Give an example of a positive externality and an example of a negative externality.
