Joe is the owner of the 7-11 Mini Mart, Sam is the owner of the SuperAmerica Mini
Mart and together they are the only gas stations in town. At the current price of $3 per
gallon, both receive total revenues of $1,000. Joe is considering cutting his price to
$2.90, which would increase his total revenue to $1,350 if Sam continues to charge $3.
If Sam’s price remains $3 after Joe cuts his price, Sam will collect $500 in revenues. If
Sam cuts his price to $2.90, his total revenues would also rise to $1,350 if Joe continues
to charge $3. Joe will collect $500 in revenues if he keeps his price at $3 while Sam
lowers his to $2.90. Joe and Sam will receive $900 each in total revenue if they both
lower their price to $2.90. You may find it easier to answer the following question if
you fill in the payoff matrix below.
Refer to the information given above. In this situation the Nash Equilibrium yields a:
A. lower payoff than each would receive if each played his dominant strategy.
B. higher payoff than each would receive if each played his dominant strategy.
C. lower payoff than each would receive if each played his dominated strategy.
D. the same payoff that each would receive if each played his dominated strategy.
In Econoland in 2000, people with incomes between $20,000 and $30,000 paid 12% of
their income in taxes and people with incomes between $30,001 and $40,000 paid 15%.
In 2000, the CPI in Econoland equaled 1.20, and it increased to 1.26 in 2001. If the
government of Econoland wants to keep households with a given real income from
being pushed up into a higher tax bracket by inflation, the $20,000-to-$30,000 bracket
will be changed in 2001 to:
