Hi guys, I might be silly to ask this question. Here is the situation I am facing and any suggestion would be appreciated.
I am writing my first serious research paper in economics. At the beginning, I simply wanted to replicate a similar study using Chinese data set (as a way to get familiar with my data set). During this process, I realize that I can do something more than a replication but that would mean a change of research direction. I have already devoted a lot to the current topic and got all the statistical tests done by now. My tutor thinks it is better to finish this one and get a publication first (although a replication would not be published in a good journal).
However, I am now in my first year of Ph.D study and do not have too much pressure about publication. So I kind of think that keeping on with the current topic would be a waste of time (especially because I have already got familiar with the data set).
I do not worry much about my situation now, since either way would work for me. But this affair alarms me that similar situations can happen in the future. I would be gratitude if you guys can share some experience or advice about the following two questions:
1. When I find another topic more worthwhile, when should I stop the current study and change a direction, and when should I continue on the current topic?
2. If I hold different views about the above question with my coauthor, what should we do?
Thanks in advance.
