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 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 equation MPC = 0.5Q, where Q is again the number of hours
engaged in lawn upkeep.

Benefits. The community decides that given all the benefits of lawn upkeep, it is
important to maintain the socially optimal number of lawn upkeep hours. To achieve
this, the community will:

C) implement a Pigouvian lawn tax of $65.
D) provide no additional funds to lawn upkeep.
