Final answer:
The result of the alternative approach to reducing pollution is that the reduction will take place where it is least expensive.
Step-by-step explanation:
The question is asking what will be the result of an alternative approach to reducing pollution if the government issues marketable permits for the current level of garbage, but the permits will shrink the weight of allowable garbage for each firm by one-fourth.
The answer is that the reduction in pollution will take place where it is least expensive.
This means that firms will reduce pollution in the most cost-effective way, which may include actions such as investing in cleaner technologies or outsourcing pollution reduction to another firm.
Therefore, the result of this alternative approach is that the overall reduction in pollution will still occur, but it will happen in a way that minimizes costs for the firms involved.
