Answers to Questions and Problems

1. This situation best represents producer-producer rivalry. Here, Southwest is a
producer attempting to steal customers away from other producers in the form of
lower prices.

2. The maximum you would be willing to pay for this asset is the present value,
which is




3.
a. Net benefits are N(Q) = 20 + 24Q – 4Q2.
b. Net benefits when Q = 1 are N(1) = 20 + 24 – 4 = 40 and when Q = 5 they are
N(5) = 20 + 24(5) – 4(5)2 = 40.
c. Marginal net benefits are MNB(Q) = 24 – 8Q.
d. Marginal net benefits when Q 1 are MNB(1) = 24 – 8(1) = 16 and when Q 5
they are MNB(5) = 24 – 8(5) = -16.
e. Setting MNB(Q) = 24 – 8Q = 0 and solving for Q, we see that net benefits are
maximized when Q = 3.

, f. When net benefits are maximized at Q = 3, marginal net benefits are zero. That is,
MNB(3) = 24 – 8(3) = 0.

, a. Net benefits are maximized at Q = 107.
b. Marginal cost is slightly smaller than marginal benefit (MC = 130 and MB = 140).
This is due to the discrete nature of the control variable.

7.
a. The net present value of attending school is the present value of the benefits
derived from attending school (including the stream of higher earnings and the
value to you of the work environment and prestige that your education provides),
minus the opportunity cost of attending school. As noted in the text, the
opportunity cost of attending school is generally greater than the cost of books
and tuition. It is rational for an individual to enroll in graduate school when his or
her net present value is greater than zero.
b. Since this decreases the opportunity cost of getting an M.B.A., one would expect
more students to apply for admission into M.B.A. Programs.

8.
a. Her accounting profits are $170,000. These are computed as the difference
between revenues ($200,000) and explicit costs ($30,000).
b. By working as a painter, Jaynet gives up the $110,000 she could have earned
under her next best alternative. This implicit cost of $110,000 is in addition to the
$30,000 in explicit costs. Since her economic costs are $140,000, her economic
profits are $200,000 - $140,000 = $60,000.
9.
a. Total benefit when Q = 2 is B(2) = 20(2) – 2*22 = 32. When Q = 10, B(10) =
20(10) – 2*102 = 0.
b. Marginal benefit when Q = 2 is MB(2) = 20 – 4(2) = 12. When Q = 10, it is
MB(10) = 20 – 4(10) = -20.
c. The level of Q that maximizes total benefits satisfies MB(Q) = 20 – 4Q = 0, so Q
= 5.
d. Total cost when Q = 2 is C(2) = 4 + 2*22 = 12. When Q = 10 C(Q) = 4 + 2*102 =
204.
e. Marginal cost when Q = 2 is MC(Q) = 4(2) = 8. When Q = 10 MC(Q) = 4(10) =
40.
f. The level of Q that minimizes total cost is MC(Q) = 4Q = 0, or Q = 0.
g. Net benefits are maximized when MNB(Q) = MB(Q) - MC(Q) = 0, or 20 – 4Q –
4Q = 0. Some algebra leads to Q = 20/8 = 2.5 as the level of output that
maximizes net benefits.
