Some economists seem to believe that all behaviour is controlled by economic priciples.
I'm starting this column where last weeks left off. I think this a little too mechanistic. People often respond to other motivations. If the cheapest way to get rid of a waste product is to spill it in the river, then that is what they will do with it. If future profits can best be enhanced by peddling cigarettes to kids, then that they will do and increase the addictive content and lie as much as they can get away with.
