Sagot :

A) Current total pollution is 200 units. It must reduce pollution by 80 units.

What does "tradeable pollution permit" mean?

The term "cap and trade" refers to trading in pollution permits. They grant businesses the authority to pollute for a set period of time and in a specified amount. Then, companies that pollute less can sell their unused pollution permits to companies that pollute more. The main benefit of a system with tradable permits is that it allows for efficient exchange, allowing one potential polluter to purchase permits from another while maintaining the same level of pollution overall.

Firms with a higher cost of reducing the pollution will buy permits rather than reduce their pollution

Firms that are able to sell their permits for more than it costs to reduce their pollution will,

Here, Firm B is the most desperate and the net buyer

Firm B buys 40 units from firm C because they offer the cheapest alternative, → has 80 pp in total so doesn't reduce pollution at all

Firm C sells its 40 pp to firm B → now has 10 pp

Firm A keeps its 70 and neither buys nor sells

The total cost of pollution reduction

= [((70-40) x $20) + (80-80) x $25) + (50-10) x $10)]

= $1000

The total cost of pollution reduction

= [((70-40) x $20) + (80-40) x $25) + (50-40) x $10)]

= $1700

Pollution reduction would cost $1000 if the permits couldn't be traded
