'Dirty' Industries: Just between you and me,
shouldn't the World Bank be encouraging MORE migration
of the dirty industries to the LDCs [Less Developed
Countries]? I can think of three reasons:
1) The measurements of the costs of health impairing
pollution depends on the foregone earnings from
increased morbidity and mortality. From this point of
view a given amount of health impairing pollution should
be done in the country with the lowest cost, which will
be the country with the lowest wages. I think the
economic logic behind dumping a load of toxic waste in
the lowest wage country is impeccable and we should face
up to that.
2) The costs of pollution are likely to be non-linear
as the initial increments of pollution probably have
very low cost. I've always though that under-populated
countries in Africa are vastly UNDER-polluted, their air
quality is probably vastly inefficiently low compared to
Los Angeles or Mexico City. Only the lamentable facts
that so much pollution is generated by non-tradable
industries (transport, electrical generation) and that
the unit transport costs of solid waste are so high
prevent world welfare enhancing trade in air pollution
and waste.
3) The demand for a clean environment for aesthetic
and health reasons is likely to have very high income
elasticity. The concern over an agent that causes a one
in a million change in the odds of prostrate cancer is
obviously going to be much higher in a country where
people survive to get prostrate cancer than in a country
where under 5 mortality is is 200 per thousand. Also,
much of the concern over industrial atmosphere discharge
is about visibility impairing particulates. These
discharges may have very little direct health impact.
Clearly trade in goods that embody aesthetic pollution
concerns could be welfare enhancing. While production is
mobile the consumption of pretty air is a non-tradable.
The problem with the arguments against all of these
proposals for more pollution in LDCs (intrinsic rights
to certain goods, moral reasons, social concerns, lack
of adequate markets, etc.) could be turned around and
used more or less effectively against every Bank
proposal for liberalization.
