19) Figure 17-2. Two companies, Acme and Pinnacle, each decide whether to produce
a good quality product or a poor quality product. In the figure, the dollar amounts are
payoffs and they represent annual profits for the two companies.
Refer to Figure 17-2. Which of the following statements is correct?
a.Acme can potentially earn its highest possible profit if it produces a good quality
product, and for that reason it is a dominant strategy for Acme to produce a good
quality product.

poor quality product, and for that reason producing a poor quality product is a dominant
strategy for both firms.

good quality product,
and for that reason producing a good quality product is a dominant strategy for
Pinnacle.
