I am currently doing my PhD (my third year just started). My field is empirical finance. My PhD consists of writing three papers and is set to last four years.
My supervisor does basically nothing. In the beginning a friend of mine who started his PhD with me and I started working on a (in my eyes) pretty meaningless research idea that my supervisor came up with. We are now nearly finished with the project and I consider it a rather bad project. The results are not interesting, methodologically it is not interesting.
It would probably suffice as one of three PhD papers, especially because I have another really good one finished already. But it stresses me out just thinking about the paper - I don’t like it at all. However, my coauthor definitely wants to finish the project. I am now thinking of dropping coauthorship. Is this the reasonable thing to do here? Is it bad to be coauthor on a bad paper, or use it as a PhD paper, respectively? Or does it not really matter as long my supervisor says it’s okay?
