Question Scenario: Private and External Benefits
A small community finds that tidy lawns and neighborhoods provide both private and external benefits.
They determine that the marginal private benefit (MPB) of lawns can be represented by the following
equation: MPB = 50 – 0.5Q, where Q is the number of hours spent on keeping lawns tidy. The marginal
private cost (MPC) of such lawn upkeep is represented by the following equation: MPC = 0.5Q, where Q
is again the number of hours engaged in lawn upkeep.
Reference: Ref 16-19
(Scenario: Private and External Benefits) Based on the information provided in the scenario Private and
External Benefits, how many hours of lawn upkeep will occur in this community, and what will be the
marginal private benefit of such upkeep?
Answer 50 hours; $50

Question Brad and Angelina are neighbors. Brad never mows his yard, rakes his leaves, or trims his hedges. His
overgrown yard is not only an eyesore, it is pulling down the value of Angelina's house. How could the
Coase theorem be used to remedy this negative externality? Does it matter whether Brad has the right to
ignore his yard or whether Angelina has the right to force him to clean it up?

Reference: Ref 16-17
(Table: Pollution and Marginal Cost of Reduction) Look at the table Pollution and Marginal Cost of
Reduction. There are two large firms in your community, Big Chemical and Mega Manufacturing, and
each is a significant source of pollution. Combined, they are producing 500 tons of pollution, and the EPA
has determined that pollution levels should be much lower, 250 tons. The table shows the current
pollution levels for each firm and the marginal cost of reducing pollution for each firm. The marginal cost is
constant.
a) If the EPA dictated that each firm must emit only 125 tons of pollution, how much total cost would the
firms incur to meet this environmental standard?
b) If the EPA distributed 125 pollution permits to each firm, each giving the firm the right to emit one ton
of pollution, which firm will sell pollution permits, and which firm will buy pollution permits?
c) Under this system of pollution permits, what is the total cost to the firms of reducing pollution to the
limit of 250 total tons?
