3. Consider the market for paper. The process of producing paper creates pollution. Assume that
the marginal damage function for pollution is given by:
MDF = 3E
where damages are measured in dollars and E is the level of emissions. Assume further that the
function describing the marginal abatement cost of emissions is given by
MAC 120-E
where benefits are measured in dollars and E is the level of emissions.
a. Graph the marginal damage function (MDF) and the marginal abatement cost function
(MAC).
b. What is the unregulated level of emissions Eu? What is the social welfare of this emissions
level?
c. Assume an existing emission quota limits emissions to E = 60. Show on the graph why this
policy is inefficient. What is the deadweight loss caused by this policy?

2. If a stock is expected to pay an annual dividend of $20 forever, what is the approximate
present value of the stock, given that the discount rate is 8%?
3. If a stock is expected to pay an annual dividend of $20 this year, what is the approximate
