Mexico and the members of OPEC produce crude oil. Realizing that it would be in their
best interests to form an agreement on production goals, a meeting is arranged and an
informal, verbal agreement is reached. If both Mexico and OPEC stick to the
agreement, OPEC will earn profits of $200 million and Mexico will earn profits of $100
million. If both Mexico and OPEC cheat, then OPEC will earn $175 million and
Mexico will earn $80 million. If only OPEC cheats, then OPEC earns $185 million and
Mexico $60 million. If only Mexico cheats, then Mexico earns $110 million and OPEC
$150 million. You may find it helpful to fill in the following payoff matrix in order to
answer the question below.
Refer to the information given above. The outcome of this game is:
A. a Nash equilibrium with both Mexico and OPEC not cheating.
B. a Nash equilibrium with both Mexico and OPEC cheating.
C. a Nash equilibrium with Mexico cheating and OPEC not cheating.

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. To Joe, leaving his price at $3 is a:
