For the operating systems game, let us now assume the intrinsic superiority of Mac is not as great and that network effects are stronger for Windows. These modifications are reflected in different payoffs. Now, the payoff from adopting windows is (50 x W) and from adopting Mac is (15+ 5 x M); n consumers are simultaneously deciding between Windows and Mac.
A. Find all nash equilibria.
B. With these new payoffs, let us now suppose that a third option exists, which is to not buy either operating system; it has a payoff of 1000. Consumers simultaneously decide among windows, mac, and no operating system. Find all nash equilibria.
