(3) Contiguous states often use tax policy to attract residents, firms, and economic activity. These "tax competitions" between states can be modeled with game theory. Suppose New Jersey currently has a state sales tax of 7 percent and Pennsylvania has a state sales tax of 6 percent. The game shown below models the effect of a reduction in each state's sales tax rate to 3 percent on each state's sales tax revenue. Assume the motivation of each state is to...
