Including article unrelated to my area in CV I have been teaching economics in a university for the past 5 years and, before that, working in the area of economics for the past 15 or so years. 20 years ago, before I studied economics, I studied French literature. Recently, I dug up my master's thesis in literature, updated and polished it, and then submitted. One of the top journals (generally considered top 5) in the subject area accepted it. I am wondering now whether I should include the article on my CV when I apply for economics teaching jobs, or even on my profile page of my current institution. I am worried it might look weird. I have some good economics articles too, so it's not that I am lacking good publications. Any thoughts? Thank you.
It’s your work, and you’ve published it, so on ethical and completeness grounds, you should include this publication on your CV.

If you wish to indicate that it’s not an active area of interest, you could always list it separately in your CV as “Other Publications,” “Publications from Master’s Degree Studies,” or something to similar effect.
