Question

What is the condition that must hold for an efficient level of pollution control in an economy? What is the condition that must hold for a cost-effective pollution control policy for a given pollution reduction target?

Answer 1

An efficient level of pollution is a concept where total benefits we get outnumber the total costs by a huge margin i.e .When we pollute some area for some benefits the effect of benefits is usually higher than the impact of pollution hence the economy neglects pollution control there since it's beneficial to people. So the condition that holds for an economy to reduce efficient level of pollution is that "the marginal costs of pollution should be higher than the benefits of pollution " then only restrictions on pollution will be possible in a state.

The condition to hold a cost effective pollution control policy is that " polluters who do it at least cost must reduce most of the pollution (here general public must take the responsibility to abate the pollution ) in an economy.
