Suppose that there are two workers, i = 1, 2, and each can “work” (si = 1) or “shirk” (si = 0). The total output of the team is 4(s1+s2) and is shared equally between the two workers. Each worker incurs private cost 3 while working and 0 while shirking. Write down this as a normal-form game. Check whether there is any dominated strategy or not. Does iterated elimination of strictly dominated strategy give us any solution?
