a. Suppose A can consume at A's preferred quantity of Q, identify A's consumer
surplus in the figure.
b. Suppose now that A is forced to consume at point Q* where the aggregate marginal
social benefit equals the marginal cost. How has A's consumer surplus changed?
C. Similarly, what is the change in consumer surplus for B and C?
d. Once again, consider society consuming at Q. Would it make sense to expand
output to Q* using Pareto's rule and the Kaldor-Hicks rule?
(Hint: Area S = Net gains of B and C-loss to A)
