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. How many hours of lawn upkeep will occur in this community, and what will
be the marginal private benefit of such upkeep?
A) 50 hours; $50
B) 45 hours; $20
C) 50 hours; $25
D) 100 hours; $50
