Mel's House of Cars is an automobile dealership that sells both new and used cars. Two
other dealerships located near Mel's pay their salespeople a straight salary - they receive
no commission for each car they sell. Mel has decided to pay all of his salespeople a
commission on all car sales. Which of the following is most likely to occur as a result of
Mel's decision?
A) Mel will have difficulty finding salespeople. Research by labor economists has
found that most employees prefer the security of a salary to the uncertainty of being
paid based on how much revenue they generate for their employers.
B) Mel will experience a principal-agent problem. Some of his salespeople will tend to
shirk because they will not be paid if they sell no cars, regardless of how hard they
work.
C) Mel will be able to hire some of the most productive salespeople who work for the
other two dealerships.
D) Mel risks violation of federal law that regulates firms' compensation policies.

Scenario 1-2

$5,000 per week. The plant owner observes, "Although the last 300 hats we produced
and sold increased our revenue by $1,000 and our costs by $1,100, we are still making
an overall profit of $5,000 per week so I think we're on the right track. We are
producing the optimal number of hats."

the incremental cost of producing the last 300 hats is
