Well it has a few, on special stories, but very few. In his media column in this Sunday's L.A. Times, David Shaw explores the Economist's success -- circulation is soaring in the U.S. post 9-11 -- and makes note of its unpredictable slant. While strongly for the Iraq war, its recent cover advised the Bush administration against the use of military tribunals: Unjust, Unwise, Un-American. On bylines, Economist editor Bill Emmott tells Shaw:
Journalists are egomaniacs and protective about their own territory and their own work, and not having bylines mitigates against that somewhat. With bylines, you worry more about your own story. With no bylines, you worry more about the whole paper because your reputation depends on the reputation of the whole paper.
