Question
A set of perfectly competitive companies
produce shoes. 1 pound of water pollution
(WP) is released into the ocean which has a
social cost of $c (per pound). The private cost
of pollution is $0 when unregulated.
i) Graph supply and demand curves and show
the output and price of the unregulated
market as well as the socially optimal output.
ii) Indicate on the graph the amount of tax
that would lead to the socially optimal level of
production.
iii) One of the companies produces Q shoes.
Say there are pollution-reducing machines, K,
which cost $1 each. When K = Ő machines,
WP = 1 pound. With higher K, WP is lower.
Give the cost-minimizing choice of WP and K
when pollution is unregulated? Please explain
with a diagram.
iv) What would be the optimal tax rate if the
government were to tax water pollution?
v) When output of shoes Q is held constant,
how do K and WP change when a pollution
tax is instated?
