I went through all authors to heck for duplicates and homonyms. The current list of homonyms is at http://ideas.repec.org/homonyms.html. Librarians are often impressed by this list... I have sent emails to 57 pairs of possible duplicate entries. I do not think there are homonyms in there. Christian Zimmermann FIGUGEGL!
