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. The clear outcome of this game is that:
A. Joe will cut his price and Sam won't.

C. Sam will cut his price and Joe won't.

Suppose that a government agency is trying to decide between two pollution reduction
policy options. Under the permit option, 100 pollution permits would be sold, each
allowing emission of one unit of pollution. Firms would be forced to shut down if they
produced any units of pollution for which they did not hold a permit. Under the
pollution tax option, firms would be taxed $250 for each unit of pollution produced.
The regulated firms all currently pollute and face varying costs of pollution reduction,
though all face increasing marginal costs of pollution reduction.
Because firms face increasing marginal costs to reduce pollution, demand for pollution
permits will be
A. upward sloping.
B. downward sloping.
C. perfectly inelastic.
D. perfectly elastic.
