Economist Arik Levinson tries to answer the question: does international trade mean more pollution? Specifically:Since the 1970s, US manufacturing output has risen by 70% but air pollution has fallen by 58%. Was this due to improved abatement technology or shifting dirty production abroad?
His answer:
The analyses here suggest that most the pollution reductions have come from improved technology, that the environmental concerns of antiglobalization protesters have been overblown, and that the pollution reduction achieved by US manufacturing will replicable by other countries in the future.
This morning's post is an FYI more than anything. Furthermore, I don't know that I'll have time today to think much about this or anything else. So, in lieu of analysis, I'm including a picture of a flying pig. Ponder Mr. Levinson's argument. Enjoy the pig.
PS. Please note also that the pig does not secretly represent any opinion of mine as to the quality of Mr. Levinson argument. It really is just a pig (in flight).
