3. Consider two sources of pollution: Source 1 and Source 2. (Think of two countries
emitting greenhouse gases, or two neighboring electric power plants emitting sulfur.)
Both sources are currently emitting 10,000 tons of pollution.
The marginal abatement costs for each source are as follows:
MAC1 = 1/3 × A1
MAC2 = 2/3 × A2
Suppose we issue each plant permits of 9100 tons. Each would have to abate by 900 tons
to meet their allotted permits. But suppose we also allow them to buy and sell permits
from each other ("cap and trade").
In the efficient outcome, which source buys permits from the other?
a. Source 1 buys permits from Source 2.
b. Source 2 buys permits from Source 1.
c. Neither, they both emit 9100 tons.
4. In the scenario above, where the two sources trade permits, what is the marginal
abatement cost for Source 1? (MAC1 = ____?)
5. In the scenario above, what would be the deadweight loss from not allowing the firms to
trade permits, requiring each to abate by 900 tons?
6. Economists primary objection to monopolies is that....
a. monopoly profits go to rich people.
b. monopolies overproduce to maximize profits.
c. monopolies have no supply curve.
d. monopolies underproduce to maximize profits.
