In the latest of a series of interviews from the Royal Economic Society Conference 2007, Romesh Vaitilingam talks to Emma Tominey about the effect of smoking during pregnancy.http://www.intute.ac.uk/socialsciences/blog/wp-content/files/tominey128.mp3%5D
Mothers who smoke during pregnancy will have smaller babies. But much of the harm is due to unobservable traits of the mother. If mums stub it out by the time they are five months pregnant, the damage is as good as undone.
