Reviewing advertisements for junior faculty positions, I noticed that it is a relatively frequent occurrence, when there is a requirement (or strong preference) for candidates to provide three working papers, along with other materials. Thinking about that aspect and considering the often lengthy process of reviewing papers in decent enough journals, I am considering a strategy of splitting my short-term future efforts (real efforts, not just on paper!) into three more or less related (perhaps, but not necessarily, adjacent) areas of study and preparing three working papers on topics from my research agenda simultaneously. I realize that due to parallel efforts the progress on each paper will be less than, if I would focus on a single topic, but, again, considering lengthy academic review process, following this strategy would allow me to have at some point three relatively developed working papers, which can be listed in CV, presented at conferences or workshops or to hiring committees and, ultimately, transformed into full-blown research papers.
Question: What do you think about such simultaneous working papers strategy? Please mention advantages, disadvantages as well as other potential considerations of my suggested approach.
