Table 17-23
Two bottled beverage manufacturers (Firm A and Firm B) determine that they could lower their costs, and thus increase
their profits, if they reduced their advertising budgets. But for the plan to work, each firm must agree to refrain from
advertising. Each firm believes that advertising works by increasing the demand for the firm’s product, but each firm also
believes that if neither firm advertises, the costs savings will outweigh the lost sales. Listed in the table below are the
individual profits for each firm.

does not advertise
Firm B

Table 17-26
Two prescription drug manufacturers (Firm A and Firm B) are faced with lawsuits from states to recover the healthcare
related expenses associated with side-effects from its drugs. Each drug manufacturer has evidence that indicates that
taking its prescription drug causes liver failure. State prosecutors do not have access to the same data used by drug
manufacturers and thus will have difficulty recovering full costs without the help of at least one of the drug
manufacturer’s studies. Each firm has been presented with an opportunity to lower its liability in the suit if it cooperates
with attorneys representing the states.

Table 17-27
Each year the United States considers renewal of Most Favored Nation (MFN) trading status with Farland (a mythical
nation). Historically, legislators have made threats of not renewing MFN status because of human rights abuses in
Farland. The non-renewal of MFN trading status is likely to involve some retaliatory measures by Farland. The payoff

against U.S. firms and the United States may not renew MFN status with Farland. The table contains the dollar value of
all trade-flow benefits to the United States and Farland.
