I am using the aer bibliography style with BibTeX. I am wanting to write out citations in the text with three or more coauthors. An easy way to do this is to use \citet*, \citep*, etc. as opposed to \citet, \citep, etc. However, there is no Oxford comma. How can I get it to include a comma before the and?
Note that this has been asked, but not answered, in a comment by @user67403 (the last comment on the question) here: Revise the AER bibliography style to write out all names if a piece has three authors
