Here’s Kaamran Hafeez, who has been contributing to The New Yorker since 2010, on using gag writers and co-crediting their work. The link will take you to his website where you’ll find all sorts of other information (a bio, work for other publications, etc.).
Here’s the link to his work on The New Yorker‘s Cartoon Bank site.
