(5) 1. One of the central ideas in economics is that informed individuals who can freely
negotiate the terms of an agreement to exchange goods and services will reach an
“efficient” allocation of resources. In the context of an agreement between a
worker and an employer, an efficient contract can be described as one where
a. further negotiations would make both the worker and the employer better off.
b. further negotiations would make both the worker and the employer worse off.
c. further negotiations would make, for example, the worker better off only by
making the employer worse off.
d. the agreement is ideal for both the worker and the employer.

Athens Landscaping hires full-time, entry-level workers to cut lawns, trim and
shape shrubs, and perform general landscaping chores at an annual salary of
$15,000. To help determine how many full-time workers it should hire, the owner
developed total-revenue projections for each of nine possible staffing levels.
a. How many workers should be hired to maximize profits? ____________
b. How did you arrive at your result?

(15) 3. Your company is considering hiring one of two applicants, Marianne or Ginger,
for a senior management position that pays $100,000 per year. If Marianne is
hired, she will reliably add $200,000 in (gross) value to your company each year.
However, there is a 50% probability that Ginger, if hired, will produce $500,000
in added value per year and a 50% chance that she will annually destroy
$100,000 of company value. Ginger’s true value to the firm (whether she is a
“star” or a “lemon”) will be known at the end of the one-year probationary
period, after which the position is considered to be “permanent.”
(10) 4.
a.
What are the expected values during the first year of hiring Marianne and
Ginger?
b.
Whom would you hire? Why?
Many consulting and law firms use lengthy probationary periods to determine
which associates will be offered partnerships, which typically come with a
permanent equity or ownership interest in the firm.
a. Why do these companies use such a costly screening process to evaluate new
hires rather than rely on more easily observable educational credentials like
college/university reputation, grade point average, or class rank?
b. Does self-selection by applicants increase or decrease the effectiveness of
using a lengthy probationary period as a screening device? Briefly explain.

(10) 5. An increasing number of persons with high-school diplomas obtained them by
passing the General Educational Development (GED) test rather than
completing twelve years of formal schooling. Several studies have shown that
GED recipients earn between 6% and 9% more than high-school dropouts who
do not obtain the GED diploma. However, when these same studies control for
innate ability (using scores on standardized tests), the return to obtaining a GED
is approximately zero.
Do these results suggest that the process of acquiring the GED is primarily a
human-capital investment that increases worker productivity or primarily a
signaling device? Explain your answer.
(10) 6. In companies where worker turnover is especially costly (for example, because
the skills learned through on-the-job training and work experience are highly
firm-specific), job tasks and the flow of work are often designed around teams to
minimize such costs. List two methods of task or work-flow design that serve
the purpose of minimizing turnover costs.
(10) 7. Other things equal, the optimal level of turnover will be [insert “higher” or
“lower” in the appropriate blank] if
a. the number of positions in the company declines dramatically as one moves
up the organizational hierarchy _____________.
b. the training undertaken in the company is largely firm-specific
_____________.

(10) 8. Describe two types of workers currently employed at other companies (”targets”)
who are least likely to cause a raiding firm to suffer the “winner’s curse” by
hiring them.
(10) 9. Asset-management firms and real estate companies often require their employees
to agree, in the event they quit, not to contact former clients for a period of at least
one year.
a. What type of “capital” (general or firm-specific) does a client list represents in
such a non-compete agreements?
b. Describe one other policy, besides a non-compete agreement, which a
business could use to deter its employees from quitting and taking a client list
or other form of intellectual property to another company.
(10) 10. In 2012, Federal Express (FedEx) offered a voluntary buyout plan to salaried
employees in its corporate, express, services, and IT divisions who had
