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.

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.
