Explain how positive externalities cause a wedge between private marginal costs and social marginal costs. Give an example of a positive externality and explain why it is, in fact, a positive externality. Draw a supply/demand diagram and add a social marginal cost curve that represents the presence of the positive externality. Explain the relationship between the equilibrium quantity and that which is socially efficient.
