Q. In a now-infamous 1991 memo, Larry Summers (then a vice president of the World Bank) argued which "the World Bank [should] be encouraging more migration of the dirty industries to the LDCs[Less Developed Countries]". One of the reasons he gave for this claim was which ‘demand for a clean environment for aesthetic also health reasons is likely to have very high income elasticity.' If summer's supposition is correct, then we should expect for wealthier countries to have cleaner environments other things equal.
