To find optimal level of output
Your firm must decide whether or not to introduce a new product. If you introduce the
new product, your rival will have to decide whether or not to clone the new product. If
you don’t introduce the new product, you and your rival will earn $1 million each. If
you introduce the new product and your rival clones it, you will lose $5 million and
your rival will earn $20 million (you have spent a lot on research and development,
and your rival doesn’t have to make this investment to compete with its clone). If you
introduce the new product and your rival does not clone, you will make $100 million
and your rival will make $0.
a. Set up the extensive form (the decision tree and the outcomes) of this game.
b. Should you introduce the new product?
c. How would your answer change if your rival has “promised” not to clone your
product?
d. What would you do if patent law prevented your rival from cloning your product?
Suppose Toyota and Honda must decide whether to make a new breed of side
impact airbags standard equipment on all models. Side-impact airbags raise the price
of each automobile by $500. If both firms make side-impact airbags standard
equipment, each company will earn profits of $1.5 billion. If neither company adopts
the side-impact airbag technology, each company will earn $0.5 billion (due to lost
sales to other automakers). If one company adopts the technology as standard
equipment and the other does not, the adopting company will earn a profit of $2
billion and the other company will lose $1 billion. If you were a decision maker at
Honda, would you make side-impact airbags standard equipment? Explain.
