Two firms, A and B, each currently emit 100 tons of chemicals into the air. The government has
decided to reduce
the pollution and from now on will require a pollution permit for each ton of
pollution emitted into the air. The
government gives each firm 40 pollution permits, which it can
either use or sell to the other firm. It costs Firm A $200 for each ton of pollution that it eliminates
before it is emitted into the air, and it costs Firm B $100 for each ton
of pollution that it eliminates
before it is emitted into the air. After the two firms buy or sell pollution permits from
each other,
we would expect that Firm A will emit
a.
20 fewer tons of pollution into the air, and Firm B will emit 100 fewer tons of pollution into the
air.
b.
100 fewer tons of pollution into the air, and Firm B will emit 20 fewer tons of pollution into the
air.
c.
50 fewer tons of pollution into the air, and Firm B will emit 50 fewer tons of pollution into the
air.
d.
20 more tons of pollution into the air, and Firm B will emit 100 fewer tons of pollution into the
air.

before it is emitted into the air, and it costs Firm B $100 for each ton
of pollution that it eliminates
before it is emitted into the air. It is likely that
a.
Firm A will buy all of Firm B's pollution permits. Each one will cost between $100 and $200.
b.
Firm B will buy all of Firm A's pollution permits. Each one will cost between $100 and $200.
c.
Both firms will use their own pollution permits.
d.
Firm A will buy some of Firm B's pollution permits. Each one will cost less than $100.
76.
Two firms, A and B, each currently dump 50 tons of chemicals into the local river. The
government has decided to
reduce the pollution and from now on will require a pollution permit for
each ton of pollution dumped into the river.
It costs Firm A $100 for each ton of pollution that it
eliminates before it reaches the river, and it costs Firm B $50
for each ton of pollution that it
eliminates before it reaches the river. The government gives each firm 20 pollution
permits.
Government officials are not sure whether to allow the firms to buy or sell the pollution permits to
each
other. What is the total cost of reducing pollution if firms are not allowed to buy and sell
pollution permits from
each other? What is the total cost of reducing pollution if the firms are
allowed to buy and sell permits from each
other?
a. $3,000; $1,500
b. $4,500; $3,500
c. $4,500; $4,000
d. $4,500; $2,500
77.
Two firms, A and B, each currently dump 20 tons of chemicals into the local river. The
government has decided to
reduce the pollution and from now on will require a pollution permit for
each ton of pollution dumped into the river.
The government gives each firm 10 pollution permits,
which it can either use or sell to the other firm. It costs Firm
A $100 for each ton of pollution that
it eliminates before it reaches the river, and it costs Firm B $50 for each ton of
pollution that it
eliminates before it reaches the river. After the two firms buy or sell pollution permits from each
other, we would expect that
a.
Firm A will no longer pollute, and Firm B will not reduce its pollution at all.
b.
Firm B will no longer pollute, and Firm A will not reduce its pollution at all.
c.
Firm A will dump 10 tons of pollution into the river, and Firm B will dump 10 tons of pollution
into the river.
d.
Firm A will increase its pollution and Firm B will reduce its pollution.
78.
Two firms, A and B, each currently dump 50 tons of chemicals into the local river. The
government has decided to
reduce the pollution and from now on will require a pollution permit for
each ton of pollution dumped into the river.
The government will sell 40 pollution permits for $75
each. It costs Firm A $100 for each ton of pollution that it
eliminates before it reaches the river,
and it costs Firm B $50 for each ton of pollution that it eliminates before it
reaches the river.
Neither firm produces any less output, but they both conform to the law. It is likely that between
the cost of permits and the cost of additional pollution abatement,
a.
Firm B will spend $3,500.
b.
Firm A will spend $4,000.
c.
Firm A will spend $4,500.
d.
Firm B will spend $3,000.
