iv. Positive consumption externality

b. In the following diagram, AB is the demand for a good (or private marginal benefit curve) and CD is the supply curve (or private marginal cost curve).

i. Identify the private market equilibrium (is it 1,2,…8 or 9?)

ii. Identify Social Marginal Cost or Social Marginal Benefit (choose from AD, CD, EF, …. etc) and socially optimum equilibria in each of the cases of 1 (a). (Choose from 1 – 9)

2. The government imposes Pigouvian taxes to resolve adverse impact of externalities by driving the equilibrium from a private equilibrium to a socially optimum equilibrium. Identify the Pigouvian tax in the case of negative consumption externality.

3. List major developments in legal doctrine, business environment and government actions in the each of the following two periods.

a. Illustrate a recession

b. Illustrate a boom
