Evaluate proposals for reducing environmental air pollution by energy

taxation and emissions trading.

Pollution is created as a by-product of output in most industries. It

can be described as an external cost to the economy as its existence

causes a loss of welfare to the population as a whole, and, in a free

market, this loss of welfare will generally go uncompensated.

However, that does not mean that the optimal level of pollution is

zero, contrary to the environmentalist presumption, as this would mean

that economic activity would have to be zero and this is illogical.

Therefore, an optimal level of pollution and corresponding economic

activity has to be found. According to the Pareto efficient, the

ideal allocation of resources occurs when nobody can be made better

off without making someone else worse off. In the case of pollution

production, this can also be defined as the point of production where

the marginal net private benefit (MNPB) of the polluter is equal to

the marginal external cost (MEC) as a whole, as shown on diagram 1, at

the level of economic activity Q*. The polluter’s total net private

benefit from production is illustrated on diagram 1 as the area below

the MNPB curve and total external cost is the area below the MEC

curve. Using this analysis, we can see that ‘A’ is the largest area of

net benefit available, thus confirming that Q* is the optimal level of

activity. However, without regulation in this market it is likely the

polluter will continue to operate at Q to maximize their own private

benefits, although this will create an unacceptable level of external

costs. Therefore, the government faces several policy choices in order

to regulate pollution and keep it at an optimal l...

also effective in lowering emissions, but only if they are auctioned

off and tradable in the market. If there is grandfathering (giving

permits only to established firms in the industry) or output based

allocation present then this would incur a greater cost to the economy

than auctioning off permits, thus increasing the optimum level of

emissions.
