We cannot give anyone the option of polluting for a fee.
This comment by former Senator Edmund Muskie reflects the view of some
environmentalists. Clean air and clean water they argue are fundamental human
rights that should not be debased by considering them in economic terms. How
can you put price on clean air and clean water? The environment is so important
they claim that we should protect it as much as possible regardless of the
cost.
Economics have little sympathy with this type of argument. Certainly
clean air and clean water have value. But their value must be compared to their
opportunity cost that is to what one must give up to obtain them. Eliminating
all pollution is impossible trying to eliminate all pollution would reverse
many of the technological advanced that allow us to enjoy a high standard of
living. Few people would be willing to accept poor nutrition inadequate medical
care or shoddy housing to make the environment as clean as possible.
Economists argue that some environmental activists hurt
their cause by not thinking in economic terms. A clean environment is a good
like other goods. Like all normal goods
it has a positive income elasticity. Rich countries can afford a cleaner
environmental than poor ones and therefore usually have more rigorous
environmental protection.
