Just taking the main quote portions only from this interesting piece for the benefits of readers:
- In a confidential memorandum in December 1991, Lawrence Summers, World Bank Chief Economist, urged his colleagues: “‘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.”
- Mr Summers elaborates: “The measurement 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”.
- Second, he says, “The costs of pollution are likely to be non-linear as the initial increments of pollution probably have very low cost. I’ve always thought 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”. Put simply, he regrets it is not economically possible to transfer waste and pollution wholesale to the developing world.
- Finally, he asserts, “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 prostate cancer is obviously going to be much higher in a country where people survive to get prostate cancer than in a country where under-5 mortality 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”.
