An incumbent firm Pilly has a product that works well but has the possibility of causing
side-effects to users. Both Pilly and an upstart firm Smirck are having the opportunity to
develop a new product without the side effects. The following table shows the expected
net return (after considering R&D costs, probability of success in product development,
and future profits) for each firm under different scenarios.
Smirck Invest
Smirck Not Invest
Pilly: $2.4 m
Smirck: -$0.1 m.
Pilly Invest
Pilly: $4.9 m
Smirck: $0
Pilly Not Invest
Pilly: $3 m
Smirck: $0.4 m
Pilly: $5 m
Smirck: $0
Assume that the two firms simultaneously choose whether to invest or not. What is the
Nash Equilibrium of this game (that is, the action choices of the two firms in the Nash
Equilibrium)? Would your answer be different if Pilly is the first mover and commits to
its choice before Smirck makes its response (that is, a sequential-move game)?
