“A Few Goodmen: Surname-Sharing Economist Coauthors”, 2014 (; backlinks; similar):
We explore the phenomenon of co-authorship by economists who share a surname. Prior research has included at most 3 economist coauthors who share a surname.
Ours is the first paper to have 4 economist coauthors who share a surname, as well as the first where such coauthors are unrelated by marriage, blood, or current campus.
